A tennis ball is a small, spherical object made of rubber, felt, and other materials. It is often used in tennis and other racquet sports. The International Tennis Federation (ITF) and the United States Tennis Association (USTA) govern the size of a standard tennis ball.
A tennis ball’s normal diameter is 6.54-6.86 cm (2.57-2.7 inches). This size is just slightly larger than a golf ball, which is usually about 1.68 inches in diameter. A tennis ball’s weight is generally between 56.0-58.5 grams, or 2.0-2.1 ounces. The temperature inside a tennis ball is also controlled. Pressures of 2.7-3.3 kg/cm2 (38-48 psi) are recommended by the ITF and USTA.
The size and weight of a tennis ball is crucial to the game because it affects how it moves and bounces. A tennis ball’s larger size and weight means it will travel further and have a higher bounce. The pressure inside the ball also influences its performance, as a ball with greater pressure will be harder and travel faster.
Tennis balls are available in a wide variety of colors, including yellow, white, green, and orange. The color of the ball does not influence its ability to play, but it does make it more difficult to spot.
In summary, the typical size of a tennis ball is 6.54-6.86 cm (2.57-2.7 inches) in diameter, with a weight of 56.0-58.5 grams and a pressure of 2.7-3.3 kg/cm2 (38-48 psi). The size and weight of a tennis ball are crucial to its performance, while the color of the ball does not influence its performance but can make it more difficult to spot.
