The Special Olympics Volleyball Rules lists several standards, such as the size of the ball and the size of courts.
According to section 3.3 of the rules, the ball should be no larger than 81 centimeters (32 inches) in circumference and weigh no more than 226 grams (8 oz). A lighter weight, leather, modified volleyball may be used, but it should be as close as possible to the regulation-size volleyball.
