Tennis balls are essential equipment for playing tennis. They are generally made from rubber and covered with felt to ensure a good grip and optimal bounce on playing surfaces. Here are some key characteristics of tennis balls:
- Size and weight : A standard tennis ball measures approximately 6.3 cm in diameter and weighs between 56.0 and 59.4 grams.
- Color : Tennis balls are traditionally yellow or white, with yellow being the most common color to improve visibility.
- Bounce : The quality of a tennis ball's bounce depends on its internal pressure. Balls are generally pressurized, but there are also "non-pressurized" balls that maintain consistency for longer.
- Durability : Tennis balls have a limited lifespan, as their felt wears out over time. Professional quality balls are often used in tournaments, while training balls are offered for a longer lifespan.
- Types : There are specific balls for different types of surfaces (clay, grass, hard), and for different levels of play (professional, recreational, junior).
