All About BALLs

The official colour used for tennis balls is yellow or white. Yellow is the most often used as this colour stands out, making it easy to follow the ball againts the colour of the court or a blue sky.

A tennis ball must be between 6.25-6.5 cm in diameter and weigh between 56.6-58.3 g to be acceptable for tournament play.

• Over-used balls lose their covering or go flat, which is bad for control and can place undue stress on your wirst and arm, so it is important to buy new balls regularly.
• If the fibres have become worn and fluffed up it will slow the ball down. When players inspect a ball prior to serving, there are looking to see if it shows any signs of wear and tear.
• Pressureless balls last for several months and maintain a uniform bounce, but bear in mind that they are less responsive and place more stress on the arm than regular pressurized balls.
• Tennis balls have to undergo rigorous testing procedures before they are approved for tournament play. However, if you are practising with your partner or using a ball machine, secong-grade balls are perfectly acceptable.
