This table describes the fees and expenses you may pay if you buy, hold or sell shares of the Portfolio. The expenses in the table do not include any fees or charges imposed by the variable insurance contract. If such fees and charges were included, the expenses would be higher.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

A fund generally pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs. The Portfolio does not pay transaction costs when buying and selling shares of other funds managed by the Advisor (the “Underlying Funds”); however, the Underlying Funds pay transaction costs when buying and selling securities for their portfolio. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio's portfolio turnover rate was 11% of the average value of its investment portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

This Example is meant to help you compare the cost of investing in the Portfolio with the cost of investing in other funds. The Example does not include any fees or charges imposed by the variable insurance contract and if such fees were included, expenses would be higher. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. The costs for the Portfolio reflect the net expenses of the Portfolio that result from the contractual expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions your costs whether you redeem or hold your shares would be:

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The VA Equity Allocation Portfolio is a “fund of funds,” which means the Portfolio generally allocates its assets among other funds managed by the Advisor (the “Underlying Funds”), although it has the ability to invest directly in securities and derivatives. The Portfolio seeks to provide investors with exposure to a diversified portfolio of global equity securities. To achieve the Portfolio’s and the Underlying Funds’ investment objectives, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s and the Underlying Funds’ designs emphasize long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.

The Portfolio seeks to provide investors with exposure to a diversified portfolio of global equity securities. The Portfolio is designed to invest substantially all of its assets in the following Underlying Funds: VA U.S. Large Value Portfolio, VA U.S. Targeted Value Portfolio, U.S. Core Equity 1 Portfolio, VA International Value Portfolio, VA International Small Portfolio, International Core Equity 2 Portfolio, Emerging Markets Core Equity 2 Portfolio, DFA International Real Estate Securities Portfolio, DFA Real Estate Securities Portfolio (each a series of DFA Investment Dimensions Group Inc.) and U.S. Large Company Portfolio (a series of Dimensional Investment Group Inc.).

Generally, the VA Equity Allocation Portfolio invests its assets in the Underlying Funds to gain exposure to equity securities with an allocation of approximately 55% to 75% of the Portfolio’s assets in U.S. equity securities, 0-15% in real estate securities, 10-35% in international developed markets equity securities, and 0-20% in emerging markets equity securities. Periodically, the Advisor will review the allocations for the Portfolio in each Underlying Fund and may adjust allocations to the Underlying Funds or may add or remove Underlying Funds in the Portfolio without notice to shareholders.

As a non-fundamental policy, under normal circumstances, the VA Equity Allocation Portfolio, through its investments in the Underlying Funds, will invest at least 80% of its net assets in equity securities. Certain Underlying Funds may invest with a moderate to meaningful emphasis on securities of smaller, lower relative price, and higher profitability companies. The Portfolio may have exposure to companies in all market capitalization ranges. The Portfolio and each Underlying Fund may invest in affiliated and unaffiliated registered and unregistered money market funds to manage its cash pending investment in other securities or to maintain liquidity for the payment of redemptions or other purposes. Investments in money market funds may involve a duplication of certain fees and expenses.

The Advisor may also increase or reduce the VA Equity Allocation Portfolio’s and/or Underlying Funds’ exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.

The VA Equity Allocation Portfolio and each Underlying Fund may gain exposure to companies associated with approved markets by purchasing equity securities in the form of depositary receipts, which may be listed or traded outside the issuer’s domicile country. The Portfolio and each Underlying Fund may use derivatives, such as futures contracts and options on futures contracts for equity securities and indices of its approved markets or other equity market securities or indices, including those of the United States, to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Portfolio or Underlying Fund.

Certain Underlying Funds may enter into foreign currency exchange transactions, including foreign currency forward contracts, in connection with the settlement of foreign securities or to transfer balances from one currency to another.

The VA Equity Allocation Portfolio and Underlying Funds may lend their portfolio securities to generate additional income.

Certain of the Underlying Funds are available for investment only by insurance company separate accounts that fund variable life and variable annuity contracts.

A summary of the investment strategies and policies of the Underlying Funds in which the VA Equity Allocation Portfolio invests as of the date of this Prospectus is described in the Portfolio’s Prospectus in the section entitled “ADDITIONAL INFORMATION ON INVESTMENT OBJECTIVES AND POLICIES—Investments in Underlying Funds.”

Principal Risks

Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a description of principal risks of investing in the Portfolio.

Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Fund of Funds Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Fund of Funds Risk: The investment performance of a fund of funds is affected by the investment performance of the underlying funds in which the fund of funds invests. The ability of a fund of funds to achieve its investment objective depends on the ability of the underlying funds to meet their investment objectives and on the Advisor’s decisions regarding the allocation of a fund of funds’ assets among the underlying funds. A fund of funds may allocate assets to an underlying fund or asset class that underperforms other funds or asset classes. There can be no assurance that the investment objective of a fund of funds or any underlying fund will be achieved. Through its investments in the underlying funds, a fund of funds is subject to the risks of the underlying funds’ investments. When a fund of funds invests in underlying funds, investors are exposed to a proportionate share of the expenses of those underlying funds in addition to the expenses of a fund of funds. Certain risks of the Underlying Funds’ investments that are principal risks of investing in the Portfolio are described below.
Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Equity Market Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Equity Market Risk: Even a long-term investment approach cannot guarantee a profit. Economic, market, political, and issuer-specific conditions and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices and periods of falling prices.
Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Foreign Securities and Currencies Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Foreign Securities and Currencies Risk: Foreign securities prices may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be forced to convert, its currency to another currency, changing its value against the U.S. dollar). The Underlying Funds do not hedge foreign currency risk.

Foreign issuers may not be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable and publicly available financial and other information about such issuers, as compared to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect to domestic issuers in U.S. courts.

Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily available public information about the issuer.
Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Emerging Markets Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Emerging Markets Risk: Securities of issuers associated with emerging market countries may be subject to higher and additional risks than securities of issuers in developed foreign markets. Numerous emerging market countries have a history of, and continue to experience serious, and potentially continuing, economic and political problems. Stock markets in many emerging market countries are relatively small, expensive to trade in and generally have higher risks than those in developed markets. Securities in emerging markets also may be less liquid than those in developed markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally have

smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.
Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Small and Mid-Cap Company Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Small and Mid-Cap Company Risk: Securities of small and mid-cap companies are often less liquid than those of large companies and this could make it difficult to sell a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are also more vulnerable than larger companies to adverse business or economic developments and they may have more limited resources.
Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Profitability Investment Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Profitability Investment Risk: High relative profitability stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause a fund to at times underperform equity funds that use other investment strategies.
Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Value Investment Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Value Investment Risk: Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause a fund to at times underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic, and industry developments than the market as a whole and other types of stocks. Value stocks also may underperform the market for long periods of time.
Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Derivatives Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.

Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Securities Lending Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Securities Lending Risk: Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover the securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences.
Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Operational Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Operational Risk: Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes. Various operational events or circumstances are outside a fund’s or its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce these operational risks through controls and procedures. However, measures that seek to reduce these operational risks through controls and procedures may not address every possible risk and may be inadequate to address these risks.
Prospectus Summary | Dimensional VA Equity Allocation Portfolio | Cyber Security Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Cyber Security Risk: A fund and its service providers’ use of internet, technology and information systems may expose the fund to potential risks linked to cyber security breaches of those technological or information systems. Cyber security breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information, customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational functionality.
