| Objective, Primary [Text Block] | rr_ObjectivePrimaryTextBlock | The Fund seeks to track the performance of a market-weighted corporate bond index that measures the investment return of investment-grade U.S. dollar-denominated bonds and is screened for certain environmental, social, and corporate governance criteria. | ||

| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | The following table describes the fees and expenses 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. | ||

| Portfolio Turnover [Text Block] | rr_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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 34% of the average value of its portfolio. | ||

| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | The following example is intended to help you compare the cost of investing in the Funds' ETF Shares with the cost of investing in other funds. It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Fund's shares. This example assumes that the shares provide a return of 5% each year and that total annual fund operating expenses remain as stated in the preceding table. You would incur these hypothetical expenses whether or not you were to sell your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be: | ||

| Strategy [Heading] | rr_StrategyHeading | <span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Principal Investment Strategies</span> | ||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund employs an indexing investment approach designed to track the performance of the Bloomberg MSCI US Corporate SRI Select Index (the “Index”). The Index is a subset of the Bloomberg U.S. Corporate Bond Index (the “Parent Index”), which serves as the universe of eligible bonds for use in constructing the Index and represents U.S. dollar-denominated, taxable, investment-grade corporate bonds. The Index excludes bonds with maturities of less than 1 year and with less than $750 million outstanding, and is screened for certain environmental, social, and governance (ESG) criteria by the Index sponsor, which is independent of Vanguard. The Index excludes the bonds of companies that the Index sponsor determines engage in (which may include manufacturing, owning, and operating), have a specified level of involvement in, and/or derive threshold amounts of revenue from certain activities or business segments related to the following: adult entertainment, alcohol, gambling, tobacco, nuclear weapons, controversial weapons, conventional weapons, civilian firearms, nuclear power, and thermal coal, oil, or gas. The level or type of involvement in, or amount of revenue earned from, certain activities or business segments that lead to exclusion by the Index sponsor can vary from one activity or business segment to another. The Index also excludes the bonds of any company that, as determined by the Index sponsor, does not meet certain standards defined by the Index sponsor with respect to an ESG controversies assessment, which measures a company’s involvement in major ESG controversies and how well they adhere to international norms and principles, or does not have an ESG controversy assessment score. Additionally, the Index excludes bonds of companies that fail to have at least one woman on their board of directors and companies for which the Index sponsor does not have board diversity data. The screens for ESG criteria described above do not apply to government-issued bonds (e.g., U.S. Treasury securities), asset-backed securities, mortgage-backed securities, and commercial mortgage-backed securities, nor do they apply to bonds issued by companies that are not researched by the Index sponsor.See the Security Selection section for more information regarding the Index exclusions. The components of the Index are likely to change over time.The Fund invests by sampling the Index, meaning that it holds a range of securities that, in the aggregate, approximates the full Index in terms of key risk factors and other characteristics. All of the Fund’s investments will be selected through the sampling process, and under normal circumstances, at least 80% of the Fund’s assets will be invested in bonds included in the Index. The Fund seeks to maintain a dollar-weighted average maturity consistent with that of the Index. | ||
| Risk [Heading] | rr_RiskHeading | <span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Principal Risks</span> | ||
| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | An investment in the Fund could lose money over short or long periods of time.You should expect the Fund's share price and total return to fluctuate within a wide range. The Fund is subject to the following risks, which could affect the Fund's performance, and the level of risk may vary based on market conditions:• Credit risk, which is the chance that a bond issuer will fail to pay interest or principal in a timely manner or that negative perceptions of the issuer’s ability to make such payments will cause the price of that bond to decline.• Interest rate risk, which is the chance that bond prices will decline because of rising interest rates. Interest rate risk should be low for short-term bond funds, moderate for intermediate-term bond funds, and high for long-term bond funds.• Income risk, which is the chance that the Fund's income will decline because of falling interest rates. Income risk is generally higher for short-term bond funds and lower for long-term bond funds.• Liquidity risk, which is the chance that a Fund may not be able to sell a security in a timely manner at a desired price.• Index sampling risk, which is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund's target index.• ESG investing risk, which is the chance that the bonds selected by the index provider for inclusion in the index based on its disclosed ESG criteria generally will underperform the market as a whole or that the particular bonds selected for the index will, in the aggregate, trail returns of other ESG funds. There are significant differences in interpretations of what it means for a company to meet ESG criteria. The index provider’s assessment of a company or of ESG criteriamay differ from an investor’s assessment. As a result, bonds selected by the index provider for inclusion in the index may not reflect the beliefs and values of any particular investor and may not exhibit positive or favorable ESG characteristics. The index provider is dependent on the availability of timely and accurate ESG data used to evaluate their ESG criteria. The ESG criteria assessed by the index provider may change over time. In addition, the Fund’s target index may, at times, become focused in bonds of a particular market sector, which would subject the Fund to proportionately higher exposure to the risks of thatsector. The index provider may evaluate security-level ESG data and, if applicable, ESG criteria that are relevant to the index only at index reviews or rebalances. Securities included in the index may cease to meet the relevant ESG criteria but may nevertheless remain in the index and the Fund until a future review or rebalance by the index provider. As a result, certain securities in the index, or the index as a whole, may not meet the relevant ESG criteria at all times.Because the Fund is an exchange-traded fund (ETF) and the Fund's shares are traded on an exchange, the Fund is subject to additional risks:• The Fund’s ETF Shares are listed for trading on Cboe BZX Exchange, Inc. and are bought and sold on the secondary market at market prices. Although it is expected that the market price of an ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.• Although the Fund’s ETF Shares are listed for trading on Cboe BZX Exchange, Inc., it is possible that an active trading market may not be maintained.• Trading of the Fund’s ETF Shares may be halted by the activation of individual or marketwide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of the Fund’s ETF Shares may also be halted if (1) the shares are delisted from Cboe BZX Exchange, Inc. without first being listed on another exchange or (2) Cboe BZX Exchange, Inc. officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. | ||
