This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Shareholder Fees Caption [Optional Text] oef_ShareholderFeesCaption Shareholder fees (fees paid directly from your investment)
Operating Expenses Caption [Optional Text] oef_OperatingExpensesCaption Annual fund operating expenses1 (expenses that you pay each year as a percentage of the value of your investment)

Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then sell all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. No fees are charged by the fund upon the sale of fund shares, so you would incur these hypothetical costs whether or not you were to sell your shares at the end of the given period.

Expense Example by, Year, Caption [Text] oef_ExpenseExampleByYearCaption Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Portfolio Turnover [Heading] oef_PortfolioTurnoverHeading Portfolio turnover
Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s investment results. Because the fund has not completed its first fiscal year of operations, information regarding the fund's portfolio turnover rate is not shown.

Strategy [Heading] oef_StrategyHeading Principal investment strategies
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

Under normal market conditions, the fund invests at least 80% of its net assets in common stocks and other equity-type securities (including preferred stock, convertible securities and hybrid securities) of large, growth companies in the United States. The investment adviser currently defines “large companies” to be companies whose market capitalizations typically fall within the range of the Russell 1000 Index. As of July 1, 2025, the smallest company for the Russell 1000 Index had a market capitalization of approximately $823.2 million and the largest company for the Russell 1000 Index had a market capitalization of approximately $3.8 trillion. The market capitalization of the companies included in the Russell 1000 Index will change with market conditions. The investment adviser currently defines “growth companies” to be companies that are included in the Russell 1000 Growth Index or exhibit the potential for growth based on historical or projected revenue or earnings, or if the investment adviser expects the company to contribute to the fund’s long-term growth of capital based on factors such as whether the company is attractively valued or is positioned to benefit from innovation, economic growth, or increasing consumer demand. The fund strives to maintain a fully invested portfolio.

The fund is nondiversified, which means it may invest a greater portion of its assets in fewer issuers than would otherwise be the case.

The investment adviser uses a system of multiple portfolio managers in managing assets. Under this approach, a portfolio is divided into segments managed by individual managers. For more information regarding the investment process of the fund, see the “Management and organization” section of this prospectus.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

Market conditions — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Events (including public health emergencies, such as the spread of infectious disease), bank failures and other circumstances in one country or region could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund’s investments may be negatively affected by developments in other countries and regions.

Issuer risks — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer’s goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer’s financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

Risk [Text Block] oef_RiskTextBlock

Market trading — The fund shares are listed for trading on an exchange and are bought and sold on the secondary market at market prices. The market prices of fund shares are expected to fluctuate, in some cases materially, in response to changes in the fund’s net asset value (“NAV”), the intraday value of the fund’s holdings, and supply and demand for the fund shares. The existence of significant market volatility, disruptions to creations and redemptions, or potential lack of an active trading market for fund shares and/or for the holdings of the fund (including through a trading halt), among other factors, may result in the shares trading significantly above (at a premium) or below (at a discount) to NAV and bid-ask spreads may widen. A bid-ask spread is the “spread” or difference between what investors are willing to pay for fund shares (the “bid” price) and the price at which they are willing to sell fund shares (the “ask” price). If you buy fund shares when their market price is at a premium or sell the fund shares when their market price is at a discount, you may pay more than, or receive less than, NAV, respectively.

Risk [Text Block] oef_RiskTextBlock

Authorized Participant concentration — Only Authorized Participants (as defined in the “Shareholder information” section below) may engage in creation or redemption transactions directly with the fund, and none of them is obligated to do so. The fund has a limited number of institutions that may act as Authorized Participants. In addition, to the extent that securities held by the fund are traded outside a collateralized settlement system, Authorized Participants may be required to post collateral on certain trades on an agency basis (on behalf of other market participants), which only a limited number of Authorized Participants may be able to do. If Authorized Participants exit the business or are unable to or elect not to engage in creation or redemption transactions, and no other Authorized Participant engages in such function, fund shares may trade at a premium or discount to the fund’s net asset value and/or at wider intraday bid-ask spreads and possibly face trading halts or delisting.

Capital Group U.S. Large Growth ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Nondiversification — As a nondiversified fund, the fund may invest a greater percentage of its assets in fewer issuers than a diversified fund. A fund that invests in a relatively smaller number of issuers is more susceptible to risks associated with a single economic, political, geographic or regulatory occurrence than a diversified fund might be. In addition, poor performance by a single issuer could adversely affect fund performance more than if the fund were invested in a larger number of issuers. The value of the fund’s shares can be expected to fluctuate more than might be the case if the fund were more broadly diversified.

Management — The investment adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.
