Volleyball Size Chart

The origins of volleyball are debatable, with some dating it back to late 1800's designed from the concept of combining basketball and tennis. Created with inclusion at its core, the ball itself has proven to play a key role in the sports success and now global appeal. Unlike other sports balls, volleyball does not have a numeric based 'standard size' system. Instead, volleyball outlines the standards and specifications, down to the inside pressure range. The volleyball national governing body, USA Volleyball, volleyball size rules include:

	Circumference	Weight	Internal Pressure
12+	65 - 67 cm (35.6-26.4")	260 - 280 g (9-10 oz.)	0.30 - 0.325 kg/cm2 (4.26-4.61 psi)
u12	65 - 67 cm (35.6-26.4")	198 - 227 g (7-8 oz.)	0.30 - 0.325 kg/cm2 (4.26-4.61 psi)

 * For younger ages, many suggest to adjust internal pressure to a level the participants are comfortable

These standard are designed to ensure the ball is age appropriate for all levels of competition. For additional information on volleyball standards and regulations, see the USAV Indoor Rules Book.
