A standard tennis court occupies a rectangular area, considerably larger than the playing surface itself to allow for player movement and ball retrieval. This includes the court’s dimensions of 78 feet (23.77 meters) in length and 27 feet (8.23 meters) in width for singles matches, expanding to 36 feet (10.97 meters) for doubles. Additional space, known as the runback or out-of-bounds area, is essential surrounding the playing surface, typically adding several feet on each side and at the baselines.
Adequate court dimensions are crucial for unrestricted movement and fair gameplay. Providing sufficient space beyond the lines permits players to reach wide shots and execute volleys comfortably. This surrounding area also contributes to safety, reducing the risk of collisions with barriers or obstructions. Historically, the standardization of court dimensions has played a key role in the development and professionalization of the sport, ensuring consistency and comparability across venues worldwide.
