| Expense [Heading] | rr_ExpenseHeading | Fees and Expenses | ||||||||||||||||||||||||||||
| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. You may also incur brokerage commissions and other charges when buying or selling shares of the fund, which are not reflected in the table or example below. |
||||||||||||||||||||||||||||
| Shareholder Fees Caption [Text] | rr_ShareholderFeesCaption | Shareholder fees (fees paid directly from your investment) | ||||||||||||||||||||||||||||

| Portfolio Turnover [Heading] | rr_PortfolioTurnoverHeading | Portfolio Turnover | ||||||||||||||||||||||||||||
| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | Portfolio Turnover 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 the fund’s 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 performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 38.2% of the average value of its portfolio. |

| Expense Example [Heading] | rr_ExpenseExampleHeading | Example | ||||||||||||||||||||||||||||
| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. The example also assumes that any current expense limitation arrangement remains in place for the period noted in the previous table; therefore, the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for which the expense limitation arrangement is expected to continue. Although your actual costs may be higher or lower, based on these assumptions your costs would be: | ||||||||||||||||||||||||||||
| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies with growth characteristics. For purposes of the fund’s 80% investment policy, the fund considers a company to have growth characteristics if the company’s securities are represented in an appropriate third-party growth-oriented index. Any derivatives that provide exposure to the investment focus suggested by the fund’s name, or to one or more market risk factors associated with the investment focus suggested by the fund’s name, are counted (as applicable) toward compliance with the fund’s 80% investment policy. While the fund may invest in companies of any market capitalization, the fund generally seeks investments in stocks of large-cap companies with one or more of the following characteristics: strong cash flow and an above-average rate of earnings growth; the ability to sustain earnings momentum during economic downturns; and occupation of a lucrative niche in the economy and the ability to expand even during times of slow economic growth. The fund’s growth-oriented investment approach to stock selection reflects the belief that when a company increases its earnings faster than both inflation and the overall growth rate of the economy, it may result in a higher stock price. At times, the fund may have a significant portion of its assets invested in the same economic sector, such as the information technology sector. The fund’s investments may include holdings in privately held companies and companies that only recently began to trade publicly. The fund is nondiversified, which means it may invest a greater percentage of its assets in a particular issuer than is permissible for a diversified fund. |

| Risk [Text Block] | rr_RiskTextBlock | The fund’s share price fluctuates, which means you could lose money by investing in the fund. | ||||||||||||||||||||||||||||
| T. Rowe Price Growth Stock Fund, Inc. | Stock investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Stock investing: Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of stocks held by the fund may decline due to general weakness or volatility in the stock markets in which the fund invests or because of factors that affect a particular company or industry. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth Stock Fund, Inc. | Growth investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Growth investing: The fund’s growth approach to investing could cause it to underperform other stock funds that employ a different investment style. Growth stocks tend to be more volatile than certain other types of stocks and their prices may fluctuate more dramatically than the overall stock market. A stock with growth characteristics can have sharp price declines due to decreases in current or expected earnings and may lack dividends that can help cushion its share price in a declining market. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth Stock Fund, Inc. | Market conditions | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Market conditions: The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including economic, political, or regulatory developments, recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as the coronavirus pandemic) and related governmental and public responses (including sanctions). Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns. |

| T. Rowe Price Growth Stock Fund, Inc. | Large-cap stocks | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Large-cap stocks: Securities issued by large-cap companies tend to be less volatile than securities issued by small- and mid-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful small- and mid-cap companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth Stock Fund, Inc. | Sector exposure | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Sector exposure: Issuers in the same economic sector may be similarly affected by economic or market events, making the fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth Stock Fund, Inc. | Information technology sector | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Information technology sector: Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources, or personnel. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth Stock Fund, Inc. | Private placements and IPOs | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Private placements and IPOs: Investments in the stocks of privately held companies and in companies that only recently began to publicly trade, such as initial public offerings or IPOs, involve greater risks than investments in stocks of companies that have traded publicly on an exchange for extended time periods. There is significantly less information available about these companies’ business models, quality of management, earnings growth potential, and other criteria that are normally considered when evaluating the investment prospects of a company. Private placements and other restricted securities held by the fund are typically considered to be illiquid and tend to be difficult to value since there are no market prices and less overall financial information available. The adviser evaluates a variety of factors when assigning a value to these holdings, but the determination involves some degree of subjectivity and the value assigned for the fund may differ from the value assigned by other mutual funds holding the same security. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth Stock Fund, Inc. | Liquidity | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity: A particular investment or an entire market segment may become less liquid or even illiquid, sometimes abruptly, which could limit the fund’s ability to purchase or sell holdings in a timely manner at a desired price. An inability to sell a portfolio holding can adversely affect the fund’s overall value or prevent the fund from being able to take advantage of other investment opportunities. Liquidity risk may be magnified during periods of substantial market volatility and unexpected episodes of illiquidity may limit the fund’s ability to pay redemption proceeds without selling holdings at an unfavorable time or at a suitable price. Large redemptions may also have a negative impact on the fund’s overall liquidity. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth Stock Fund, Inc. | Risk Nondiversified Status [Member] | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Nondiversification: As a nondiversified fund, the fund has the ability to invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. As a result, 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 fund’s share price can be expected to fluctuate more than that of a similar fund that is more broadly diversified. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth Stock Fund, Inc. | Active management | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Active management: The fund’s overall investment program and holdings selected by the fund’s investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies. |
||||||||||||||||||||||||||||
| T. Rowe Price Growth Stock Fund, Inc. | Cybersecurity breaches | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund’s assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund’s service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality. |
