How big is a tennis ball?

The International Tennis Federation (ITF) establishes the regulations governing a tennis ball’s measurements. A tennis ball’s diameter must be between 2.575 inches (6.5 cm) and 2.700 inches (6.85 cm) in order to adhere to these rules.

The circumference of the majority of regulation tennis balls is 8.25 inches (20.96 cm). However, depending on the brand and model, a tennis ball’s circumference can vary slightly, ranging from 8.09 inches (20.6 cm) to 8.48 inches (21.5 cm).


It’s interesting to note that the ITF also stipulates that logos on tennis balls are limited in size. The logo’s maximum height and width are 1.26 inches (32mm) and 2.05 inches (52mm), respectively.

The size of children’s and junior tennis balls varies based on their age group. intended for.

How much does a tennis ball weigh?

To comply with ITF regulations, a tennis ball’s mass must be between 1.98 and 2.10 oz (56.0 and 59.4 g).

What is the volume of a tennis ball?

A tennis ball has a volume of about 9.15 cubic inches (150 cm³). Remember that a tennis ball’s overall volume can fluctuate slightly along with its diameter.




What are tennis balls made of and how are they made?

The materials used to make modern tennis balls are glue, rubber, and synthetic felt. A tennis ball dropped from a height of 100 inches onto a concrete surface must bounce between 53 and 58 inches in order to comply with ITF regulations. Tennis balls typically have a PSI of 25–27 in order to achieve this bounce.

In order to give a tennis ball a firmer texture, a soft rubber is first ground between two heavy rollers. After that, this rubber is formed into plug-shaped discs, which are then reshaped to take on the shape of half-shells, which make up the interior structure of the balls.

The two halves are “vulcanized,” or fused together, by applying a layer of adhesive and applying high heat and pressure. Just prior to the two halves being joined together, a high-pressure air jet is injected into the balls during this process.

The exterior is smoothed after the ball is formed and the two halves are joined. The inner shell of the ball is then filled with adhesive before felt is added. After that, the balls undergo one more vulcanizing procedure to ensure that the felt and rubber shell are securely attached. The balls are finally dried, which creates their fuzzy exterior.

What color is a tennis ball?

The question of whether a tennis ball is green or yellow is one that causes a lot of confusion. Tennis balls used in professional competitions are required by the International Tennis Federation (ITF) to be either white or yellow, more precisely “optic yellow.” For design purposes, this shade—which is sometimes referred to as “fluorescent yellow”—is represented by the hex code #ccff00. In conclusion, the ITF’s official documentation indicates that tennis balls used in grand slam competitions are actually yellow in color, not green!

Children’s tennis balls are clearly marked in red, orange, or green for simple identification. These balls are frequently bigger than those used by adults, in addition to being lighter.

When did tennis balls become yellow?

The use of yellow tennis balls dates back to the early 1970s. Tennis balls were primarily black or white until 1972. Tennis balls are now yellow because of the need for improved visibility during matches that are televised on color TVs, which gained popularity in the 1970s. The ITF declared in 1972 that:

“The ball shall be white or yellow in color, with a uniform outer surface composed of a fabric cover.”

Why are tennis balls fuzzy?

Tennis balls have a synthetic felt exterior covering, which makes them fuzzy. The felt has a big impact on the ball’s characteristics because it creates drag when the ball travels through the air, greatly slowing it down. The ball moves so quickly that many serves from professional players would probably be impossible to return if it weren’t for the felt layer and the fuzziness of the ball. For this reason, before serving, players frequently examine multiple balls to find the smoothest one.When struck with a racket’s strings, the fuzz not only moderates speed but also adds grip and traction, giving players more control over their shots and increased spin potential. The fuzz also increases the ball’s lifespan and helps it bounce consistently.

Do the numbers on tennis balls mean anything?

There are various reasons why tennis balls might have numbers on them. For instance, it can be simple to forget which balls belong to which player when playing tennis at a club or facility with several courts, particularly if the balls are the same make and model.

Junior tennis balls frequently feature numbers as well. This is done to make the age range of the “stage” of development they are intended for very evident. For instance, Vermont Stage 2 Balls have the word “Stage 2” printed on them and are intended for players between the ages of 8 and 9.
Lastly, to identify the kind of court surface that their tennis balls are intended for, some manufacturers imprint numbers on them. Number 1 balls are typically meant for slower-paced courts, like clay courts; number 2 balls are meant for medium-paced courts, like asphalt hard courts; and number 3 balls are meant for use on fast-paced courts, like grass courts.


What are pressurized tennis balls?

Tennis balls that have been pressurized are those that have had air pumped into them under extreme pressure. The air increases the internal pressure of the balls, improving their bounce.

When compared to pressureless tennis balls, pressureless tennis balls are more durable, but pressure-filled tennis balls perform better and are typically packaged and sold in cans. Professional matches and tournaments use pressurized tennis balls, but they are changed out frequently because they lose their bounce and turn “dead” rather quickly.

Why are tennis balls pressurized?

When hit with a tennis racket, the extra air inside a pressurized tennis ball improves the ball’s bounce and responsiveness. Compared to a pressureless tennis ball, a pressurized ball will typically bounce higher, move through the air more quickly, and be more responsive to spin. Professional tennis tournaments always use inflated tennis balls.

Why are pressurized tennis balls sealed in a can?

Cans help to provide an air-tight seal that prevents air from escaping from the tennis balls’ cores, ensuring they maintain their internal pressure. If air escaped from the balls, then the performance and bounce would be compromised before the can was opened.

What are pressureless tennis balls?

Cans help to provide an air-tight seal that prevents air from escaping from the tennis balls’ cores, ensuring they maintain their internal pressure. If air escaped from the balls, then the performance and bounce would be compromised before the can was opened.

Comparing the performance of pressurized and pressureless tennis balls

There is a slight difference in performance between pressured and pressureless balls. For instance, pressurized tennis balls typically lend themselves more easily to spin application. Because of this, practicing with pressurized tennis balls can help you translate your practiced skills more effectively into a controlled match if you’re a serious player hoping to compete in tournaments.

Because they are more affordable and have superior durability, recreational players will frequently choose the pressureless tennis balls because they don’t really care about the performance differences.


Although the dimensions, weight, and color of tennis balls used in senior competitive matches and tournaments are standardized, there are numerous varieties and categories of tennis balls that can be purchased. We’ll examine some of the traits and attributes of each kind of tennis ball in this section.

Tour/Tournament Tennis Balls

Tour or tournament tennis balls are what you should buy if you’re searching for the best tennis balls money can buy. Tennis balls used on the tour are pressurized and closely resemble the balls used in Grand Slam competitions like Wimbledon. Unlike training balls, they are made with a better felt that does not fray as quickly. A more consistent amount of air resistance is made possible by the felt’s durability, which results in a more predictable flight, trajectory, and bounce. Tour tennis balls are mostly meant to be used in competitions, but serious tennis players and coaches also use them for drills.

Practicing with tour tennis balls facilitates the transference of training skills to competition, as they closely resemble the properties of balls used in a tournament or regulation match. Because of their unique DuraCore center, our Vermont Classic Tour tennis balls offer exceptional shape and air retention and are approved by the ITF. For anyone searching for the best tennis balls available, these are the ideal option.

Practice Tennis Balls

In comparison to professional or tour tennis balls used in official competitions, practice balls are more affordable, have a higher level of durability, and usually last longer. The bounce of practice tennis balls comes from an inner rubber shell rather than from air pressure, giving them a pressureless design. Tennis balls that are pressurized lose air over time, but balls that are pressureless and have a thick rubber shell tend to bounce for a lot longer. Vermont Training Tennis Balls are the ideal option for both amateur and educational settings. They provide an unmatched degree of durability and can endure for several months, contingent upon usage frequency. The practice tennis balls are appropriate for all court surfaces and come in packs of 60.

Kids’ Tennis Balls

Most small children cannot use standard senior tennis balls because they are too heavy and bounce too high. When introducing kids to tennis in the 1980s and 90s, instructors and coaches would frequently use old tennis balls that had a lower bounce. These days, tennis balls that are standardized for children’s varying heights and strengths can be purchased by coaches.

Junior tennis balls bounce significantly lower and are lighter and larger than senior tennis balls. Children can hit and return the balls with greater ease because the balls also move through the air more slowly.

The following table lists the tennis balls that are suggested for kids of various ages: For young children, using a regular tennis ball can be very frustrating because it bounces too high and too quickly for them to catch up to. Children can play tennis with greater success and enjoyment when they use balls that are appropriate for their age.

The Mini Red Tennis balls from Vermont are especially made for kids in stages 3 and 4 of mini tennis. Compared to regular senior tennis balls, the red balls are larger, lighter, and fly through the air much more slowly. Additionally, because the balls bounce much lower, groundstrokes are much easier to perform and proper technique is encouraged.

Foam Tennis Balls

Foam tennis balls are an excellent option for introducing young children to the game of tennis. The larger, lighter foam balls are an excellent substitute for regular tennis balls because kids might not have the strength or size to return them. The foam tennis balls are incredibly light and travel through the air more slowly, which makes it simpler for kids to track and react to them as they improve their hand-eye coordination. Standard tennis balls don’t usually result in any serious injuries, but foam tennis balls completely remove the possibility of impact injuries, making the game safe and entertaining for kids. With their lower bounce and versatility, foam tennis balls are easier to hit when using proper body alignment and technique. Both indoors and outdoors are suitable uses for them.

Because the foam balls move slower and bounce lower, it makes them easier to hit, which also reduces the likelihood of children losing motivation and getting frustrated. The Vermont Foam Tennis Balls are intended for kids under the age of eight. They come in packs of three, twelve, or seventy-two balls and in two sizes, 80 mm and 90 mm. The 90mm foam tennis balls are bigger and move through the air more slowly than the 80mm balls because of their size. The junior tennis balls are compliant with LTA and ITF regulations and are appropriate for short and mini-tennis matches due to their high-density foam construction.


When should you replace tennis balls?

New balls are introduced following the first seven games and then every ninth game at major tournaments like the US Open and Wimbledon. This guarantees that the balls are maintained in almost perfect condition throughout the matches, since minute variations in placement and speed frequently mean the difference between winning and losing.

Amateur tennis players will replace their balls less frequently because they typically do not have the large budget of a grand slam tournament. Tennis players frequently test their balls to see if they need to be replaced by listening to how they bounce, how easy they are to squeeze, and how they sound. In order to look for fraying, some players will also visually examine the balls’ exteriors.

Tennis balls without pressure will have a much longer lifespan than pressurized balls because their bounce is generated by a rubber shell rather than internal air pressure. Whether or not pressureless tennis balls need to be replaced usually depends on personal preference or if there is a noticeable change in the balls’ characteristics, like noticeable felt exterior fraying or decreased bounce. The type of tennis ball you use, the kind of court you play on, the force with which players hit the ball, and the frequency of play all affect how long a tennis ball lasts.

What tennis ball accessories can you buy?

Regardless of the kind of tennis balls you use, you might want to spend money on accessories to make your matches run more smoothly and your practice sessions more productive.

Tennis ball machines are ideal for solitary practice sessions, but tennis ball pick-up tubes, ball mowers, and ball carts/hoppers are very popular because they keep the courts neat and orderly.

You can up the ante on your practice sessions with tennis ball launchers and machines. With its adjustable trajectory that allows you to serve the balls at different heights and angles, the Baseliner Slam Tennis Ball Machine can serve balls at up to 40 mph.

Coaches and owners of tennis courts love our tennis ball mowers and hoppers because they make it easy for them to gather and serve tennis balls, keeping the court and games operating smoothly.

Can you recycle tennis balls?

An estimated 70,000 tennis balls are used at the US Open alone, out of the 300 million tennis balls produced worldwide annually. There are a lot of tennis balls there! Many tennis balls wind up in landfills because pressurized tennis balls only last a few matches at most.

Tennis ball recycling is possible through local non-profit organizations (NGOs) or specialized recycling companies. While there are NGOs dedicated to recycling tennis balls, as of this writing there were only a few in the United States.

Tennis balls can be repurposed or given to kennels or dog charities if you are unable to find a recycling solution.

Can you wash tennis balls?

Occasionally, amateur tennis players will wash their balls if they become muddy or covered in dirt. It is advisable to consult the manufacturer’s instructions or get in touch with them to make sure that cleaning procedures won’t harm the balls.

If you do decide to wash a tennis ball, it is recommended to rinse it with lukewarm water and use a sponge to remove any mud or dirt. Take care not to puncture the ball’s exterior felt. When you are done cleaning, leave the ball to dry out of direct sunlight.
