When the tournaments for the most prestigious championship on earth are heating up at Wimbledon, many best tennis players in the world take to the courts. The top seeds, including Djokovic, Murray, and Federer, as well as Williams, Sharapova, and Ivanovic, usually fight tooth and nail to win. Over the course of the two-week Championship, an average of 2,000 Slazenger tennis balls were utilised per day, making up no less than 54,000 in total.

But, why are there so many tennis balls in UK needed, then? In addition to the 660 total matches played during Wimbledon, the balls also begin to lose their bounce as the competition progresses.


All depends on the air
Nothing compares to the feel of a new tennis ball with plenty of bounce. The air injected into the ball is what gives it this bounce. Pressure is produced as a result of the air pressing up against the ball's inside. The air that is trapped inside the ball is driven inward as it lands on the ground. The bounce is caused when the inner air pushes back and launches the ball off the ground.

Greater internal pressure than external pressure

Tennis balls, in contrast to other types of balls, have more air pressure inside than outside. Around 27 pounds per square inch of force is acting on the interior of the ball. In contrast, just 13.7 pounds per square inch of force are produced by the air pressure outside.

Why are the containers under pressure? Ever ponder the pressurisation of tennis ball containers?

Because the can has been pressured to ensure that the equal amount of air is pushing on both the inside and outside of the balls, you will hear a "pop" when you open the can. This keeps them lively and fresh.

More air begins to push against the inside of the balls when the container is opened and they are placed in play. Small amounts of air begin to leak out of the balls as they age, reducing internal pressure.

By lessening the quantity of air that the ball experiences as it hits the ground, bounce is decreased. Tennis balls without pressure are an alternative to pressurised tennis balls. But do they compare? What are the variations? Which choice is superior, then?

Pressureless tennis balls

In a nutshell, pressureless tennis balls have:

● More bounce: When balls are initially removed from the container, they seem more "lively." To match the internal pressure of the tennis balls, the container is pressured to 14 psi. To stop the pressurised gas from leaking, the can has been vacuum sealed.

● More spin response - These tennis balls can generate more spin because they are lighter than pressureless tennis balls.

● Greater speed - Pressurized balls move more quickly than pressureless balls because they are lighter in mass.

However, these advantages are just temporary. These balls will lose their original bounce two to four weeks (or less) after being opened, making them all but unplayable for the dedicated tennis player. These balls lose their bounce when the pressurised gas inside them escapes, giving them a "dead" or "wooden" sensation.

Tennis balls without pressure

Conversely, pressureless balls have a tendency to feel a touch "dead" right away. However, as the ball's felt fabric cover ages and the rubber inside deteriorates, these balls become bouncy.

While that may sound advantageous, the larger weight of these balls means that they will hit your racquet harder. Additionally, you must hit them with more force overall, using both your arm and the rest of your body. Injury rates may rise as a result. Additionally, while the balls may get bouncy over time, their ability to spin gets weaker. A definite drawback in today's world as so many players want to add spin to their serves and ground strokes.


Thus, the only true alternative if you want to play any kind of competitive tennis is to use pressurised balls. Again, only pressurised balls will give you the proper bounce and spin qualities when you practise with another player to enhance your game. However, pressureless tennis balls are a fantastic choice because they won't lose their bounce over time if you want to use balls for rebound or machine practice.


Tennis players can enjoy playing with properly pressurised tennis balls by utilising PressureBalls, eliminating the need to replace or put up with soft tennis balls. Instead, until the felt is fully worn down, the balls continue to bounce like new balls! It is by far the most affordable option for tennis fans.
