There are three types of volleyballs:

 

Standard indoor volleyball

Youth indoor volleyball

Beach volleyball

All volleyballs are round and consist of eighteen panels of leather (synthetic or genuine) wrapped around a bladder. Each section consists of three panels or rows. A standard (adult, indoor) volleyball may be solid white or a combination of three different easily distinguishable colors. A youth indoor volleyball is slightly smaller than a standard volleyball to accommodate children's use. Contrary to popular belief, indoor balls and beach volleyballs weigh the same. Balls used in beach volleyball are slightly softer (lower internal pressure) and a bit larger than indoor volleyballs, and are brightly colored.

 

 

There are several brands of competitive volleyballs in use, including, but not limited to:

 

Tachikara

Molten

Wilson

Mikasa

Baden

Spalding

Most of these brands also make cheaper variations for recreational (non-competitive) use.

 

 

Mikasa makes the official balls of FIVB (beach and indoor).

Molten makes the official ball of USA Volleyball (indoor).
