| Pacer Swan SOS Moderate (February) ETF | Buffered Loss Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Buffered Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to buffer against Underlying ETF losses. Despite the intended Buffer, a shareholder could lose their entire investment. The Fund’s strategy seeks to deliver returns that match the share price return of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are bought on the day on which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of each Investment Period. In the event an investor purchases Shares after the date on which the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the Buffer that the Fund seeks to provide may not be available and the investor may not get the full benefit of the Buffer. The Fund might not achieve its objective in certain circumstances. The Fund does not provide principal protection and an investor may experience significant losses on its investment, including loss of its entire investment. |
| Pacer Swan SOS Moderate (February) ETF | Cap Change Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cap Change Risk. A new Cap is established at the beginning of each Investment Period and is dependent on prevailing market conditions. As a result, the Cap may rise or fall from one Investment Period to the next and is unlikely to remain the same for consecutive Investment Periods. |
| Pacer Swan SOS Moderate (February) ETF | Capped Upside Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Capped Upside Risk. The Fund’s strategy seeks to provide returns that match those of the Underlying ETF for Shares purchased on the first day of an Investment Period and held for the entire Investment Period, subject to a pre-determined upside Cap. If an investor does not hold its Shares for an entire Investment Period, the returns realized by that investor may not match those the Fund seeks to achieve. If the Underlying ETF experiences gains during an Investment Period, the Fund will not participate in those gains beyond the Cap. In the event an investor purchases Shares after the first day of an Investment Period and the Fund has risen in value to a level near to the Cap, there may be little or no ability for that investor to experience an investment gain on their Shares. |
| Pacer Swan SOS Moderate (February) ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The OCC acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. |
| Pacer Swan SOS Moderate (February) ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks: ◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market. ◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments. ◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices. ◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund.

| Pacer Swan SOS Moderate (February) ETF | ETF Risks, Authorized Participants ("APs"), Market Makers, And Liquidity Providers Concentration Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Pacer Swan SOS Moderate (February) ETF | ETF Risks, Cash Redemption Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market. |
| Pacer Swan SOS Moderate (February) ETF | ETF Risks, Costs Of Buying Or Selling Shares Of The Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments. |
| Pacer Swan SOS Moderate (February) ETF | ETF Risks, Shares Of The Fund May Trade At Prices Other Than NAV Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount).

Shares of the Fund will be bought and sold in the secondary market at market prices. |
| Pacer Swan SOS Moderate (February) ETF | ETF Risks, Trading Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund. |
| Pacer Swan SOS Moderate (February) ETF | FLEX Options Correlation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | •FLEX Options Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. Factors that may influence the value of the FLEX Options, other than changes in the value of the Underlying ETF, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the Underlying ETF. |
| Pacer Swan SOS Moderate (February) ETF | FLEX Options Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |
| Pacer Swan SOS Moderate (February) ETF | FLEX Options Valuation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser or sub-adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. |
| Pacer Swan SOS Moderate (February) ETF | Investment Period Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Period Risk. The Fund’s investment strategy is designed to deliver returns that match the share price return of the Underlying ETF if Shares are bought on the day on which the Fund enters into the FLEX Options (i.e., the first day of an Investment Period) and held until those FLEX Options expire at the end of the Investment Period. In the event an investor purchases Shares after the first day of an Investment Period or sells Shares prior to the expiration of the Investment Period, the value of that investor’s investment in Shares may not be buffered against a decline in the value of the Underlying ETF and may not participate in a gain in the value of the Underlying ETF up to the Cap for the investor’s investment period. |
| Pacer Swan SOS Moderate (February) ETF | Large-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. |
| Pacer Swan SOS Moderate (February) ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio manager will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective. |
| Pacer Swan SOS Moderate (February) ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Market risk is the risk that a particular security, or Shares in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates, and perceived trends in securities prices. Shares could decline in value or underperform other investments. In addition, local, regional, or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Pacer Swan SOS Moderate (February) ETF | New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it could ultimately liquidate. The Fund’s distributor does not maintain a secondary market in Fund shares. |
| Pacer Swan SOS Moderate (February) ETF | Special Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Special Tax Risk. The Fund intends to qualify as a “regulated Investment company” (“RIC”), however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, its hedging strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended. If, in any year, the Fund fails to qualify as a regulated investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation. Certain options on an ETF may not qualify as “Section 1256 contracts” under Section 1256 of the Code, and disposition of such options will likely result in short-term or long-term capital gains or losses depending on the holding period. In the event that a shareholder purchases Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.
|
| Pacer Swan SOS Moderate (February) ETF | Suitability Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Suitability Risk. The Fund’s unique characteristics (i.e., the imperative of holding Shares for the entire Investment Period, the Cap and Buffer) distinguish it from other investment products and may make it an unsuitable investment for some investors. |
| Pacer Swan SOS Moderate (February) ETF | Underlying ETF Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Underlying ETF Risk. The Fund invests in FLEX Options that reference an ETF, which subjects the Fund to certain of the risks of owning shares of an ETF, as well as the types of instruments in which the Underlying ETF invests. The value of an ETF will fluctuate over time based on fluctuations in the values of the securities held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, ETFs are subject to authorized participant concentration risk, market maker risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses, and other factors. |
| Pacer Swan SOS Moderate (February) ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | You can lose money on your investment in the Fund. |
| Pacer Swan SOS Moderate (February) ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
| Pacer Swan SOS Moderate (March) ETF | Buffered Loss Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Buffered Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to buffer against Underlying ETF losses. Despite the intended Buffer, a shareholder could lose their entire investment. The Fund’s strategy seeks to deliver returns that match the share price return of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are bought on the day on which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of each Investment Period.

The Fund might not achieve its objective in certain circumstances. The Fund does not provide principal protection and an investor may experience significant losses on its investment, including loss of its entire investment. |
| Pacer Swan SOS Moderate (March) ETF | Cap Change Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cap Change Risk. A new Cap is established at the beginning of each Investment Period and is dependent on prevailing market conditions. As a result, the Cap may rise or fall from one Investment Period to the next and is unlikely to remain the same for consecutive Investment Periods. |
| Pacer Swan SOS Moderate (March) ETF | Capped Upside Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Capped Upside Risk. The Fund’s strategy seeks to provide returns that match those of the Underlying ETF for Shares purchased on the first day of an Investment Period and held for the entire Investment Period, subject to a pre-determined upside Cap. If an investor does not hold its Shares for an entire Investment Period, the returns realized by that investor may not match those the Fund seeks to achieve. If the Underlying ETF experiences gains during an Investment Period, the Fund will not participate in those gains beyond the Cap. In the event an investor purchases Shares after the first day of an Investment Period and the Fund has risen in value to a level near to the Cap, there may be little or no ability for that investor to experience an investment gain on their Shares. |
| Pacer Swan SOS Moderate (March) ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The OCC acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Market risk is the risk that a particular security, or Shares in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates, and perceived trends in securities prices. Shares could decline in value or underperform other investments. In addition, local, regional, or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Pacer Swan SOS Moderate (March) ETF | New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it could ultimately liquidate. The Fund’s distributor does not maintain a secondary market in Fund shares. |
| Pacer Swan SOS Moderate (March) ETF | Special Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Special Tax Risk. The Fund intends to qualify as a “regulated Investment company” (“RIC”), however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, its hedging strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended. If, in any year, the Fund fails to qualify as a regulated investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation. Certain options on an ETF may not qualify as “Section 1256 contracts” under Section 1256 of the Code, and disposition of such options will likely result in short-term or long-term capital gains or losses depending on the holding period. In the event that a shareholder purchases Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

| Prospectus [Line Items] | |
| Risk [Text Block] | Suitability Risk. The Fund’s unique characteristics (i.e., the imperative of holding Shares for the entire Investment Period, the Cap and Buffer) distinguish it from other investment products and may make it an unsuitable investment for some investors. |
| Pacer Swan SOS Moderate (March) ETF | Underlying ETF Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Underlying ETF Risk. The Fund invests in FLEX Options that reference an ETF, which subjects the Fund to certain of the risks of owning shares of an ETF, as well as the types of instruments in which the Underlying ETF invests. The value of an ETF will fluctuate over time based on fluctuations in the values of the securities held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, ETFs are subject to authorized participant concentration risk, market maker risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses, and other factors. |

| Pacer Swan SOS Moderate (March) ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
| Pacer Swan SOS Moderate (May) ETF | Buffered Loss Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Buffered Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to buffer against Underlying ETF losses. Despite the intended Buffer, a shareholder could lose their entire investment. The Fund’s strategy seeks to deliver returns that match the share price return of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are bought on the day on which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of each Investment Period. In the event an investor purchases Shares after the date on which the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the Buffer that the Fund seeks to provide may not be available and the investor may not get the full benefit of the Buffer. The Fund might not achieve its objective in certain circumstances. The Fund does not provide principal protection and an investor may experience significant losses on its investment, including loss of its entire investment. |
| Pacer Swan SOS Moderate (May) ETF | Cap Change Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cap Change Risk. A new Cap is established at the beginning of each Investment Period and is dependent on prevailing market conditions. As a result, the Cap may rise or fall from one Investment Period to the next and is unlikely to remain the same for consecutive Investment Periods. |
| Pacer Swan SOS Moderate (May) ETF | Capped Upside Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Capped Upside Risk. The Fund’s strategy seeks to provide returns that match those of the Underlying ETF for Shares purchased on the first day of an Investment Period and held for the entire Investment Period, subject to a pre-determined upside Cap. If an investor does not hold its Shares for an entire Investment Period, the returns realized by that investor may not match those the Fund seeks to achieve. If the Underlying ETF experiences gains during an Investment Period, the Fund will not participate in those gains beyond the Cap. In the event an investor purchases Shares after the first day of an Investment Period and the Fund has risen in value to a level near to the Cap, there may be little or no ability for that investor to experience an investment gain on their Shares. |
| Pacer Swan SOS Moderate (May) ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The OCC acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. |
| Pacer Swan SOS Moderate (May) ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks: ◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market. ◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments. ◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices. ◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund.

| Pacer Swan SOS Moderate (May) ETF | FLEX Options Correlation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. Factors that may influence the value of the FLEX Options, other than changes in the value of the Underlying ETF, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the Underlying ETF. |
| Pacer Swan SOS Moderate (May) ETF | FLEX Options Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |
| Pacer Swan SOS Moderate (May) ETF | FLEX Options Valuation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser or sub-adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. |
| Pacer Swan SOS Moderate (May) ETF | Investment Period Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Period Risk. The Fund’s investment strategy is designed to deliver returns that match the share price return of the Underlying ETF if Shares are bought on the day on which the Fund enters into the FLEX Options (i.e., the first day of an Investment Period) and held until those FLEX Options expire at the end of the Investment Period. In the event an investor purchases Shares after the first day of an Investment Period or sells Shares prior to the expiration of the Investment Period, the value of that investor’s investment in Shares may not be buffered against a decline in the value of the Underlying ETF and may not participate in a gain in the value of the Underlying ETF up to the Cap for the investor’s investment period. |
| Pacer Swan SOS Moderate (May) ETF | Large-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. |
| Pacer Swan SOS Moderate (May) ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio.

Shares could decline in value or underperform other investments. In addition, local, regional, or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors, and industries more significantly than others.

The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. Factors that may influence the value of the FLEX Options, other than changes in the value of the Underlying ETF, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the Underlying ETF. |
| Pacer Swan SOS Moderate (June) ETF | FLEX Options Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser or sub-adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. |
| Pacer Swan SOS Moderate (June) ETF | Investment Period Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Period Risk. The Fund’s investment strategy is designed to deliver returns that match the share price return of the Underlying ETF if Shares are bought on the day on which the Fund enters into the FLEX Options (i.e., the first day of an Investment Period) and held until those FLEX Options expire at the end of the Investment Period. In the event an investor purchases Shares after the first day of an Investment Period or sells Shares prior to the expiration of the Investment Period, the value of that investor’s investment in Shares may not be buffered against a decline in the value of the Underlying ETF and may not participate in a gain in the value of the Underlying ETF up to the Cap for the investor’s investment period. |
| Pacer Swan SOS Moderate (June) ETF | Large-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. |
| Pacer Swan SOS Moderate (June) ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio manager will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective. |
| Pacer Swan SOS Moderate (June) ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Market risk is the risk that a particular security, or Shares in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates, and perceived trends in securities prices. Shares could decline in value or underperform other investments. In addition, local, regional, or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Pacer Swan SOS Moderate (June) ETF | New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it could ultimately liquidate. The Fund’s distributor does not maintain a secondary market in Fund shares. |
| Pacer Swan SOS Moderate (June) ETF | Special Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Special Tax Risk. The Fund intends to qualify as a “regulated Investment company” (“RIC”), however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, its hedging strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended. If, in any year, the Fund fails to qualify as a regulated investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation. Certain options on an ETF may not qualify as “Section 1256 contracts” under Section 1256 of the Code, and disposition of such options will likely result in short-term or long-term capital gains or losses depending on the holding period. In the event that a shareholder purchases Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.
|
| Pacer Swan SOS Moderate (June) ETF | Suitability Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Suitability Risk. The Fund’s unique characteristics (i.e., the imperative of holding Shares for the entire Investment Period, the Cap and Buffer) distinguish it from other investment products and may make it an unsuitable investment for some investors. |
| Pacer Swan SOS Moderate (June) ETF | Underlying ETF Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Underlying ETF Risk. The Fund invests in FLEX Options that reference an ETF, which subjects the Fund to certain of the risks of owning shares of an ETF, as well as the types of instruments in which the Underlying ETF invests. The value of an ETF will fluctuate over time based on fluctuations in the values of the securities held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, ETFs are subject to authorized participant concentration risk, market maker risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses, and other factors. |

| Pacer Swan SOS Moderate (June) ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
| Pacer Swan SOS Moderate (August) ETF | Buffered Loss Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Buffered Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to buffer against Underlying ETF losses. Despite the intended Buffer, a shareholder could lose their entire investment. The Fund’s strategy seeks to deliver returns that match the share price return of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are bought on the day on which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of each Investment Period. In the event an investor purchases Shares after the date on which the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the Buffer that the Fund seeks to provide may not be available and the investor may not get the full benefit of the Buffer. The Fund might not achieve its objective in certain circumstances. The Fund does not provide principal protection and an investor may experience significant losses on its investment, including loss of its entire investment. |
| Pacer Swan SOS Moderate (August) ETF | Cap Change Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cap Change Risk. A new Cap is established at the beginning of each Investment Period and is dependent on prevailing market conditions. As a result, the Cap may rise or fall from one Investment Period to the next and is unlikely to remain the same for consecutive Investment Periods. |
| Pacer Swan SOS Moderate (August) ETF | Capped Upside Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Capped Upside Risk. The Fund’s strategy seeks to provide returns that match those of the Underlying ETF for Shares purchased on the first day of an Investment Period and held for the entire Investment Period, subject to a pre-determined upside Cap. If an investor does not hold its Shares for an entire Investment Period, the returns realized by that investor may not match those the Fund seeks to achieve. If the Underlying ETF experiences gains during an Investment Period, the Fund will not participate in those gains beyond the Cap. In the event an investor purchases Shares after the first day of an Investment Period and the Fund has risen in value to a level near to the Cap, there may be little or no ability for that investor to experience an investment gain on their Shares. |
| Pacer Swan SOS Moderate (August) ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The OCC acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. |
| Pacer Swan SOS Moderate (August) ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | •ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks: ◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market. ◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments. ◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices. ◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund.

(the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund.

| Pacer Swan SOS Moderate (September) ETF | ETF Risks, Authorized Participants ("APs"), Market Makers, And Liquidity Providers Concentration Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Pacer Swan SOS Moderate (September) ETF | ETF Risks, Cash Redemption Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market. |
| Pacer Swan SOS Moderate (September) ETF | ETF Risks, Costs Of Buying Or Selling Shares Of The Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments. |
| Pacer Swan SOS Moderate (September) ETF | ETF Risks, Shares Of The Fund May Trade At Prices Other Than NAV Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices. |

| Pacer Swan SOS Moderate (September) ETF | FLEX Options Correlation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. Factors that may influence the value of the FLEX Options, other than changes in the value of the Underlying ETF, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the Underlying ETF. |
| Pacer Swan SOS Moderate (September) ETF | FLEX Options Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |
| Pacer Swan SOS Moderate (September) ETF | FLEX Options Valuation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser or sub-adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data.
|
| Pacer Swan SOS Moderate (September) ETF | Investment Period Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Period Risk. The Fund’s investment strategy is designed to deliver returns that match the share price return of the Underlying ETF if Shares are bought on the day on which the Fund enters into the FLEX Options (i.e., the first day of an Investment Period) and held until those FLEX Options expire at the end of the Investment Period. In the event an investor purchases Shares after the first day of an Investment Period or sells Shares prior to the expiration of the Investment Period, the value of that investor’s investment in Shares may not be buffered against a decline in the value of the Underlying ETF and may not participate in a gain in the value of the Underlying ETF up to the Cap for the investor’s investment period. |
| Pacer Swan SOS Moderate (September) ETF | Large-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. |
| Pacer Swan SOS Moderate (September) ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio manager will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective. |
| Pacer Swan SOS Moderate (September) ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Market risk is the risk that a particular security, or Shares in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates, and perceived trends in securities prices. Shares could decline in value or underperform other investments. In addition, local, regional, or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Pacer Swan SOS Moderate (September) ETF | New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it could ultimately liquidate. The Fund’s distributor does not maintain a secondary market in Fund shares. |
| Pacer Swan SOS Moderate (September) ETF | Special Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Special Tax Risk. The Fund intends to qualify as a “regulated Investment company” (“RIC”), however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, its hedging strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended. If, in any year, the Fund fails to qualify as a regulated investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation. Certain options on an ETF may not qualify as “Section 1256 contracts” under Section 1256 of the Code, and disposition of such options will likely result in short-term or long-term capital gains or losses depending on the holding period.In the event that a shareholder purchases Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price. |
| Pacer Swan SOS Moderate (September) ETF | Suitability Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Suitability Risk. The Fund’s unique characteristics (i.e., the imperative of holding Shares for the entire Investment Period, the Cap and Buffer) distinguish it from other investment products and may make it an unsuitable investment for some investors. |
| Pacer Swan SOS Moderate (September) ETF | Underlying ETF Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Underlying ETF Risk. The Fund invests in FLEX Options that reference an ETF, which subjects the Fund to certain of the risks of owning shares of an ETF, as well as the types of instruments in which the Underlying ETF invests. The value of an ETF will fluctuate over time based on fluctuations in the values of the securities held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, ETFs are subject to authorized participant concentration risk, market maker risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses, and other factors. |
| Pacer Swan SOS Moderate (September) ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | You can lose money on your investment in the Fund. |
| Pacer Swan SOS Moderate (September) ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
| Pacer Swan SOS Moderate (November) ETF | Buffered Loss Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Buffered Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to buffer against Underlying ETF losses. Despite the intended Buffer, a shareholder could lose their entire investment. The Fund’s strategy seeks to deliver returns that match the share price return of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are bought on the day on which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of each Investment Period. In the event an investor purchases Shares after the date on which the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the Buffer that the Fund seeks to provide may not be available and the investor may not get the full benefit of the Buffer. The Fund might not achieve its objective in certain circumstances. The Fund does not provide principal protection and an investor may experience significant losses on its investment, including loss of its entire investment. |
| Pacer Swan SOS Moderate (November) ETF | Cap Change Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cap Change Risk. A new Cap is established at the beginning of each Investment Period and is dependent on prevailing market conditions. As a result, the Cap may rise or fall from one Investment Period to the next and is unlikely to remain the same for consecutive Investment Periods. |
| Pacer Swan SOS Moderate (November) ETF | Capped Upside Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Capped Upside Risk. The Fund’s strategy seeks to provide returns that match those of the Underlying ETF for Shares purchased on the first day of an Investment Period and held for the entire Investment Period, subject to a pre-determined upside Cap. If an investor does not hold its Shares for an entire Investment Period, the returns realized by that investor may not match those the Fund seeks to achieve. If the Underlying ETF experiences gains during an Investment Period, the Fund will not participate in those gains beyond the Cap. In the event an investor purchases Shares after the first day of an Investment Period and the Fund has risen in value to a level near to the Cap, there may be little or no ability for that investor to experience an investment gain on their Shares. |
| Pacer Swan SOS Moderate (November) ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The OCC acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. |
| Pacer Swan SOS Moderate (November) ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks: ◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Cash Redemption Risk.

In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund.

The Fund’s strategy seeks to provide returns that match those of the Underlying ETF for Shares purchased on the first day of an Investment Period and held for the entire Investment Period, subject to a pre-determined upside Cap. If an investor does not hold its Shares for an entire Investment Period, the returns realized by that investor may not match those the Fund seeks to achieve. If the Underlying ETF experiences gains during an Investment Period, the Fund will not participate in those gains beyond the Cap. In the event an investor purchases Shares after the first day of an Investment Period and the Fund has risen in value to a level near to the Cap, there may be little or no ability for that investor to experience an investment gain on their Shares. |
| Pacer Swan SOS Moderate (December) ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The OCC acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. |
| Pacer Swan SOS Moderate (December) ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | •ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks: ◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market. ◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments. ◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices. ◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund.

| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. Factors that may influence the value of the FLEX Options, other than changes in the value of the Underlying ETF, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the Underlying ETF. |
| Pacer Swan SOS Moderate (December) ETF | FLEX Options Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser or sub-adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data.
|
| Pacer Swan SOS Moderate (December) ETF | Investment Period Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Period Risk. The Fund’s investment strategy is designed to deliver returns that match the share price return of the Underlying ETF if Shares are bought on the day on which the Fund enters into the FLEX Options (i.e., the first day of an Investment Period) and held until those FLEX Options expire at the end of the Investment Period. In the event an investor purchases Shares after the first day of an Investment Period or sells Shares prior to the expiration of the Investment Period, the value of that investor’s investment in Shares may not be buffered against a decline in the value of the Underlying ETF and may not participate in a gain in the value of the Underlying ETF up to the Cap for the investor’s investment period. |
| Pacer Swan SOS Moderate (December) ETF | Large-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. |
| Pacer Swan SOS Moderate (December) ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio.

There can be no guarantee that the Fund will meet its investment objective. |
| Pacer Swan SOS Moderate (December) ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Market risk is the risk that a particular security, or Shares in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates, and perceived trends in securities prices. Shares could decline in value or underperform other investments. In addition, local, regional, or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Pacer Swan SOS Moderate (December) ETF | New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it could ultimately liquidate.

| Pacer Swan SOS Moderate (December) ETF | Special Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Special Tax Risk. The Fund intends to qualify as a “regulated Investment company” (“RIC”), however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, its hedging strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended. If, in any year, the Fund fails to qualify as a regulated investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation. Certain options on an ETF may not qualify as “Section 1256 contracts” under Section 1256 of the Code, and disposition of such options will likely result in short-term or long-term capital gains or losses depending on the holding period.In the event that a shareholder purchases Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price. |

| Pacer Swan SOS Moderate (December) ETF | Underlying ETF Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Underlying ETF Risk. The Fund invests in FLEX Options that reference an ETF, which subjects the Fund to certain of the risks of owning shares of an ETF, as well as the types of instruments in which the Underlying ETF invests. The value of an ETF will fluctuate over time based on fluctuations in the values of the securities held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, ETFs are subject to authorized participant concentration risk, market maker risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses, and other factors. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
| Pacer Swan SOS Laddered Moderate ETF | Buffered Loss Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Buffered Loss Risk. There can be no guarantee that the Underlying Swan Moderate ETF will be successful in its strategy to buffer against reference asset losses. Despite the intended buffer, a shareholder (such as the Fund) could lose its entire investment. The Underlying Swan Moderate ETF’s strategy seeks to deliver returns that match the reference asset (up to the cap), while limiting downside losses, if shares are bought on the day on which the Underlying Swan Moderate ETF enters into the options and held until those options expire at the end of each Investment Period. In the event the Fund purchases Underlying Swam ETF shares after the date on which the options were entered into or sells shares prior to the expiration of the options, the buffer that the Underlying Swan Moderate ETF seeks to provide may not be available and the Fund may not get the full benefit of the buffer. The Underlying Swan Moderate ETF might not achieve its objective in certain circumstances. The Underlying Swan Moderate ETF does not provide principal protection and the Fund may experience significant losses on its investment, including loss of its entire investment. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Cap Change Risk.

Underlying Swan Moderate ETF transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Underlying Swan Moderate ETF. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Underlying Swan Moderate ETF and, in turn, the Fund. An Underlying Swan Moderate ETF may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The OCC acts as guarantor and central counterparty with respect to the FLEX Options. As a result, the ability of an Underlying Swan Moderate ETF to meet its objective depends on the OCC being able to meet its obligations.

|
| Pacer Swan SOS Laddered Moderate ETF | Fixed Income Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed Income Risk. The Fund’s investments may expose the Fund to risks related to fixed income securities. Fixed income securities will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by a fund. On the other hand, if rates fall, the value of the fixed income securities generally increases. The current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives may increase the risk of rising interest rates. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. The value of direct or indirect investments in fixed income securities may be affected by the inability of issuers to repay principal and interest or illiquidity in debt securities markets. |

| Prospectus [Line Items] | |
| Risk [Text Block] | High Portfolio Turnover Risk. At times, the Fund may have a portfolio turnover rate substantially greater than 100%. A high portfolio turnover rate would result in correspondingly greater transaction expenses, including brokerage commissions, dealer mark ups and other transaction costs, on the sale of securities and on reinvestment in other securities and may result in reduced performance and the distribution to shareholders of additional capital gains for tax purposes. These factors may negatively affect the Fund’s performance. |

FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist.

This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
