What is the standard size of a volleyball?

The standard size of a volleyball is defined by its circumference, which must be within the range of 65-67 cm. This specification ensures uniformity across competitive play, allowing players to have a consistent experience in matches and training.

A volleyball within this size range provides the appropriate balance of weight and grip for players, which is essential for skills such as serving, passing, and spiking. The design and materials of the ball, combined with the standard circumference, directly impact its performance, durability, and feel during play. Maintaining these standards is crucial for official competitions governed by organizations like the FIVB (Fédération Internationale de Volleyball) and USAV (USA Volleyball).
