Squash Balls

Squash balls are between 29.5 and 40.5 mm in diameter, with a mass of 23 – 25 g.  They are made with 2 pieces of rubber compound, glued together to form a hollow sphere. 

Different balls are provided for varying temperature and atmospheric conditions, and standards of player.  Small coloured dots on the ball indicate its dynamic level ( bouciness ).  “Double-yellow-dot” balls are for competition standard.  For areas of high altitude such as Mexico City, Calgary, Denver and Johannesburg, “orange-dot” ball are used.

Squash balls heat up upon hitting.  As a result, the air inside the ball pressurized, and the rubber compound becomes more resilient, thus bounce higher.   This is why balls are warm up prior to competition.
