The United States Tennis Association said: “Men and women use the same ball in terms of size, pressure and design. The sole difference is that the men compete with an extra-duty felt ball while the women compete using a regular-duty felt ball.”
The purpose of using two different tennis balls is simple: To make the women’s game a little faster.
This difference is important, because the density of the yellow felt coating has a huge impact on the speed and action of the ball.
How are the balls without compression compared to regular and compressed balls?
Non-compression balls are generally stiffer than compression balls, except for one brand called Tretorn. However, unlike compression balls, uncompressed balls are more durable, with better bounce retention. When the outer felt is lost, balls without compression fly faster, bounce and spin more. But then, the ball was not suitable for a tennis match.
