What Is A Tennis Ball?

tennis ball is a ball designed for the sport of tennis, a racquet sport.

Tennis balls are fluorescent yellow at major sporting events, but in recreational play can be virtually any color.

Tennis balls are covered in a fibrous felt covering a rubber compound which modifies their aerodynamic properties, and each has a white curvilinear oval covering it.

Modern tennis balls must conform to certain criteria for size, weight, deformation, and bounce criteria to be approved for regulation play.

The International Tennis Federation (ITF) defines the official diameter as 6.54–6.86 cm (2.57–2.70 inches). Balls must have masses in the range 56.0–59.4 g (1.98–2.10 ounces).

Decaying Bounce?

Tennis balls begin to lose their bounce as soon as the tennis ball can is opened. Modern regulation tennis balls are kept under pressure until they need to be used.

Balls intended for use at high altitudes have lower initial pressure, and inexpensive practice balls are made without any internal pressure at all.

A tennis ball can be tested for bounce by dropping it from a height of 254 cm (100 inches) onto concrete such as some tennis courts. A bounce between 135 and 147 cm (53-58 inches) is acceptable – if the game is taking place at sea-level and 20 degrees Celcius (68 degrees Fahrenheit) with a relative humidity of 60%.

High-altitude balls have different results when tested at sea-level.


Pre-1925, tennis balls were packed in wrapped paper and paperboard boxes, but then Wilson introduced cardboard tubes.

In 1926, the Pennsylvania Rubber Company released a hermetically sealed pressurized metal tube that held three balls with a churchkey to open the top.

Nearing the 1980s, plastic cans with a full-top pull-tab seal plastic lid that could fit three to four balls per can.

Pressureless balls (aka practice balls) often come in net bags or buckets since they don’t require a pressurized seal.

What Are The Different Types Of Tennis Balls?

With the different playing levels of tennis, there come certain types of balls that are suitable for the level of the game you’re playing in. Using the correct ball is very important and can help overall performance and improve your game.

There are three types of tennis balls:

  3. Beginner Level

Professional Level Tennis Balls

Once you reach the highest level of this sport, finding the right ball is essential and can greatly affect the outcome of the match. Victory at the top level often lies in the smallest margins and players need every advantage they can get on their opponent.

Professional level balls are designed to last longer and not as easily worn. They also operate better at different altitudes and offer peak consistency.

Penn ATP and Wilson Regular Duty are two types that are used at major tournaments.

Intermediate Level Tennis Balls

Intermediate level balls still offer great quality, but they’re marketed toward the regular player who is experienced but not exactly a professional. They can bring a great playing experience to the course, but they’re not the same as professional level balls.

They won’t last as long and aren’t durable, but will do the job if you’re an enthusiastic tennis player who likes to get out on the course a couple times each week.

Babolat Championship and Dunlop Absorber are two types of intermediate tennis balls you can get your hands on easily.

Beginner Level Tennis Balls

Beginner balls are perfect for any new player to the game. They are durable, often come in large packages (bigger than 3-4), and are cheaper than every other ball out there.

Beginner balls are designed specifically with beginners in mind, which means they bounce slower – making them easier to hit and practice with.

Using beginner balls are a great way to get a base level of skill quickly. Whether you’re brand new or it’s been a few years – beginner balls are the place to start.
