Tennis ball is specifically designed for tennis game. Occasional tournaments/ games adopt any colour of ball but in standard or international matches fluorescent yellow (Which some people call as green or may be fluorescent green as well). It’s made from pressurised core rubber material covered by high quality cloth i.e. fibrous felt. Cloth is mixed up by wool and nylon.
Ball could be yellow or white and size for green ranges form 2.5 – 2.70” (Inches), 56 – 59.4 Grams (1.97 – 2.09 Ounces). Complete ball specification table is given below as defined by ITF.

Balls are changed during game depending on different court surfaces or terms agreed by officials.
Balls have numbers printed to differentiate from one group of balls from other .
New / Beginner Player
A lot of peoples like and play tennis. So if someone is new then he must choose ball wisely. Because it’s not only court that matters of your performance but ball is as well. Ball is manufactured by many popular brands of Europe, USA, Thailand, Philippines, Indonesia and China.
It’s good for newbie’s to take a fairly slow, non-pressurised & soft ball which will won’t make you surprise in bounce ( i.e. spin, speed, Height). ITF recommends balls in Stage 3 (red) ball & it’s two sub-categories balls for beginners.
When it comes to experienced players or for tough, rough and long training sessions, ball with different and professional properties needed such as playing capacity remains intact for max. For this purpose no-pressurised having thick rubber & felt layer with hard core is more resistant in almost all common conditions.
Slower Ball Vs. Fast Balls
Balls are manufactured in different categories by manufacturers, due to different court surfaces, temperature & altitude conditions. Other conditions are applied on balls such as size, weight, Diameter & Rebound. Categories are enlisted as below. Balls are divided into following categories.
Type 1: For fast courts like Grass
Type 2: For Medium Surface courts as Hard Courts
Type 3: For Slow Surfaces like Clay Courts
High Altitude: For faster speed and high bounce
ITF uses all types of balls in international matches manufactured from different regions.
Ball for Younger Players
Most talked about balls are usually for Professional & mature players. But to invoke game in young blood and to have new energetic players, Its need of hour to encourage younger players. For this ITF started campaign “Play & Stay”.
For this slower balls with different colours have been introduced for different age groups of younger players. You may read our article for age group details.
- Stage 3 (Red) Foam Ball – Marked by Half Red felt, Un-pressurised
- Stage 3 (Red) Standard Ball – Slowest One
- Stage 2 (Orange) Standard Ball – Normal Size & Un-pressurised ball
- Stage 1 (Green) Standard Ball – Normal Size have half Pressure.
Pressurised Vs. Non Pressurised Ball
In pressurised ball is made from soft rubber and air has been injected in core. It makes ball easy to play, control and felts cover imparts spin properly. If this ball is used on rough space it’ll deform it quickly and spin is deteriorated quickly. Hard courts are good for it but bounces high and difficult to control ball.
Clay courts’s surface is softer and it make it spin but humidity is absorbed which makes ball bigger & Heavier. Pressurised balls are not low cost but expensive & less durable. It’s not suitable for intensive practice or game.
Non-Pressurised Balls are also called pressure less ball is good for practice because it retains it’s bounce. It’s hard to hit this ball as obvious no pressure is there. It’s good to use with machines as it lasts long, saves lot of money and time. These are not sold in sealed containers but in bags.
