The rubber is about 3 mm thick and the cover is also about 3 mm thick. If the cloth cover wears down to say 2 mm thickness, the ball will become softer. The ball will also become softer if some of the compressed air leaks out (but this doesn’t happen with pressureless balls).

What are the layers of a tennis ball?

How do I choose the right tennis ball thickness?

The choice you make largely depends on the court’s surface, with a different thickness offering a potential advantage to your play. In essence, extra duty balls tend to be better for harder, faster surfaces, whereas regular duty balls give more of an advantage on slower courts.

What is a type 1 tennis ball?

A slightly harder, fast-speed ball (Type 1) which is intended for use on ‘slower’ court surfaces, and a larger, slow-speed ball (Type 3) for faster courts. The rules require ball diameters to hover between 2.57 and 2.70 inches but each manufacturer can choose their own felt makeup and weaves (often a nylon-wool blend).

What is the difference between Clay and regular duty tennis balls?

The idea is that the clay court will absorb more of the impact of the ball, so regular duty balls require less felt. The felt on a regular duty ball is also designed to remain compact for a longer duration, which helps speed the ball up, balancing out the slower court surface.
