What are Tennis Balls Made Of?

Are you curious in what is inside of a tennis ball? From a spherical sewn envelope of leather or linen pack with rags, horsehair, or similar material we make real tennis balls. But was it always like that?

Clover-Leaf Balls

India rubber, derived from a vulcanization process created by Charles Goodyear in the 1850s, was used to make lawn tennis balls from the commencement of the sport in the 1870s.

They were originally manufactured entirely of rubber, but the wear and playability of them were enhanced by stitching flannel around the rubber ‘core’. Making the core hollow and pressurizing it with gas allowed the ball to be created fast.

Originally, cores were made using the ‘clover-leaf’ technique, in which an uncured rubber sheet was pressed into the shape of a three-leaf clover and then joined into an approximately spherical area using specially designed machinery. Chemicals that produce pressurizing gas were introduced before the assembly was closed, and they were triggered when the core was molded into a spherical form in heated cavities.

The Ball of Yellow

Historically, they were either black or white, depending on the color of the court’s background. However, the International Tennis Federation (ITF) incorporated yellow tennis balls into the rules of tennis in 1972 (and it is also in 2022), after studies showed that this color was more visible to television viewers. Meanwhile, Wimbledon maintained to utilize the original white ball until 1986, when it switched to yellow ones.

How Many Tennis Balls do I Need for a Tournament?

Matches usually begin with six fresh balls for the server. You need to change them every nine games, according to the regulations. However, after seven games, the initial set of balls is replaced because it is also used for the pre-match warm-up.

We use new ones every nine games for the duration of the match. As a result, the number of them used in a game is defined by the number of games played.

We can calculate how many of them there are in sets by following:

  • Add up all of the games you’ve played.
  • Take 7 out of the total.
  • Multiply the remaining by nine. If it is an integer, you’re fine to go; if it’s not, choose the lowest integer closest to it.
  • Increase the integral number by one. And there you have it!!! You know how many sets of them they need in a match.

What to Do With Old Tennis Balls?

When they lose their bounce, what do you do? If you don’t have a dog and find yourself with an abundance of an unplayable tennis ball, check out this list of things you can do with them.


  1. Cleaners for the floors. Clean cobwebs from hard-to-reach places or your ceiling with them on the end of a broom. They are also useful for removing scuffs from hardwood flooring. Make an X in the top of the ball and insert a broom handle or long dowel. This is a quick and easy solution to erase black spots or scuff marks without scrubbing!
  2. Protective floor coverings. This is a simple task. Cut an X in the top of each one and place it on the bottoms of your chair legs. They may also be useful on the bottoms of walkers, making it much easier for residents to maneuver them about. You may not be concerned about safeguarding your floor if you spend a lot of time outside on a deck. On the other hand, your chair legs may become trapped between the slats. Tennis balls, you guessed it, will prevent this from happening.
  3. Lantern. One tennis ball is all you need. Put your one ball in the trash container. Place a tiny LED touch light towards the top of the container. Simply shake the container to switch it on or off. It will make contact with the light and perform the task for you.
  4. The chair is quite comfortable. We can slice them in half and glue to the back of a wooden chair, or we can make holes in the chair and we can insert them through. It’s considerably more comfortable to move your back over a group of tennis balls than it is to sit in a hard-backed wooden chair. Consider it a massage chair for artsy people!

The best approach to maintain them is to be pressurized to keep them unopened. They lose pressure as soon as they are opened. Instead, keep used ones in a pressurized storage container at ambient temperature to keep them pressurized.

Why do tennis players take 3 balls?

Tennis players may inspect three or more balls before serving in order to choose one smooth and one fluffy. The first serve is made with a smooth ball. The smooth one travels quicker than an older because the hairs have been flattened, making it more difficult to make contact and return.
