Loss of Pressure
Tennis balls are pressurized, and this pressure naturally decreases over time. After several hours of play, the ball loses its ability to bounce correctly and becomes more difficult to control. A ball that no longer bounces like it did at the beginning is a clear sign that it needs to be replaced.
Felt Wear
The felt covering the ball plays an essential role in its flight and bounce behavior. When this felt starts to degrade and fray, the ball loses precision and speed. A ball with worn felt also tends to offer less control during shots.
Average Lifespan of a Tennis Ball
For Recreational Play
For a recreational player who plays occasionally, a tennis ball can last between 6 and 9 hours of active play. However, even after this period, it can be reused, but will have a less consistent bounce and will be much slower.
For Competitive Players
This varies depending on the level of play, but the ball will have an acceptable lifespan of between 1 and 3 hours of active play. After this period, the ball's felt and bounce will be of poorer quality. The bounce will be lower and the ball slower, while also losing a certain level of control.
For Professionals
In professional tournaments, balls are changed very frequently, usually after 7 to 9 games, which is approximately 30 to 60 minutes of play, due to the intensity of rallies. Professionals cannot afford to play with worn balls, as this would affect their performance.
