A tennis ball is a hollow, pressurized ball used in the sport of tennis. It is designed to bounce off the ground evenly and consistently, allowing players to hit it back and forth over a net.
The first tennis balls were made of wool or cloth and filled with feathers or horsehair. Modern tennis balls are made of pressurized rubber with a felt covering. The pressurized air inside the ball gives it its bounce, and the felt covering provides grip for players’ rackets.
In the next section, we’ll take a closer look at the different parts of a tennis ball and discuss the materials used in its construction.

- Felt covering
- Designed for bounce
- Used in the sport of tennis
Tennis balls are an essential part of the game of tennis, and their unique construction allows them to perform as intended.
Pressurized rubber core
The pressurized rubber core is the heart of a tennis ball. It is made of a durable rubber compound that is inflated to a high pressure, typically between 12 and 14 pounds per square inch (psi). The pressurized air gives the ball its bounce and liveliness.
The rubber core is also responsible for the ball’s durability. It is designed to withstand the repeated impacts of being hit by a tennis racket, and it can last for several matches before needing to be replaced.
The size and weight of the rubber core are strictly regulated by the International Tennis Federation (ITF). The core must be between 6.54 and 6.86 centimeters (2.575 and 2.700 inches) in diameter, and it must weigh between 56.0 and 59.4 grams (1.975 and 2.115 ounces).
The pressurized rubber core is an essential part of a tennis ball. It gives the ball its bounce, durability, and performance characteristics.
In the next section, we’ll take a closer look at the felt covering of a tennis ball.
Felt covering
The felt covering of a tennis ball is made of a durable woven fabric, typically wool or nylon. It is glued to the rubber core and serves several important functions.
First, the felt covering provides grip for players’ rackets. This allows players to hit the ball with control and accuracy.
Second, the felt covering protects the rubber core from wear and tear. It also helps to keep the ball clean and free of debris.
Third, the felt covering gives the ball its characteristic yellow color. The color of the felt is regulated by the ITF, and it must be a shade of yellow that is easily visible against different court surfaces.
The felt covering is an essential part of a tennis ball. It provides grip, protection, and visibility.
Designed for bounce
Tennis balls are designed to bounce evenly and consistently, allowing players to hit the ball back and forth over a net.
- Pressurized core
The pressurized rubber core gives the ball its bounce. The air inside the core is compressed, and when the ball is hit, the air expands, propelling the ball forward.
- Felt covering
The felt covering helps to control the bounce of the ball. The nap of the felt creates friction with the court surface, which slows the ball down and prevents it from bouncing too high.
- Size and weight
The size and weight of the ball also affect its bounce. Larger balls bounce higher than smaller balls, and heavier balls bounce lower than lighter balls.
- Court surface
The type of court surface also affects the bounce of the ball. Balls bounce higher on hard courts than on clay courts.
The bounce of a tennis ball is an important factor in the game. Players need to be able to control the bounce of the ball in order to hit it successfully.
Used in the sport of tennis
Tenis balls are an essential part of the sport of tennis. They are used in all levels of play, from recreational to professional. Tennis balls are hit back and forth over a net between two or four players. The game is played on a rectangular court, and the ball must bounce within the court boundaries in order to remain in play.
There are different types of tennis balls available, each designed for a specific type of play. For example, pressureless tennis balls are used for recreational play, while pressurized tennis balls are used for professional play. Press pressurized balls have a longer life and are more consistent in their bounce than pressureless balls.
Choosing the right tennis ball is important for playing the game safely and effectively. Players should choose a ball that is appropriate for their skill level and the type of court they are playing on.

Tips
Here are a few tips for choosing and using tennis balls:
Tip 1: Choose the right type of tennis ball for your skill level and the type of court you are playing on.
Pressureless tennis balls are best for recreational players and beginners, while pressurized tennis balls are best for experienced players and competitive matches. Hard courts require a ball with a higher bounce, while clay courts require a ball with a lower bounce.
Tip 2: Store your tennis balls in a cool, dry place away from direct sunlight.
Tennis balls should be stored in a pressurized container to maintain their bounce. Extreme temperatures and humidity can damage tennis balls and shorten their lifespan.
Tip 3: Hit the ball in the center of the racket face.
This will give you the most control and power over your shots. Aim to hit the ball at the 7 o’clock position on the racket face for a topspin shot, and at the 1 o’clock position for a backspin shot.
Tip 4: Keep your eye on the ball.
This will help you to track the ball and make solid contact. Focus on the point where the ball will bounce and swing your racket through the ball with a smooth, fluid motion.
