It depends if we are talking about Indoor Volleyball or Beach Volleyball. Indoor/ court Volleyball: 6 players each side Beach Volleyball: 2 players per team/ sode
As this goes without saying, the main difference between beach volleyball and indoor volleyball are the locations in which the games are played; beach volleyball being played on a beach court, and indoor volleyball being played on an indoor court. While indoor volleyball requires 6 athletes with fixed positions from each team on the court at one time, beach volleyball only requires 2, in most instances of competitive play. Other differences occur in areas such as the court. For example, a regulation indoor court is 30 feet by 30 feet on each side, while a beach court is 26.3 by 26.3 on each side. Also, a beach court lacks an attack line, or a ten foot line. Hope this helps!
In traditional indoor volleyball, six players are on the court at once.
