The playing court is a rectangle measuring 18m X 9m surrounded by a rectangular free zone of maximum of 2m and with a space free from any obstructions to a height of a minimum surface. The surface must be flat, horizontal and uniform. For international competitions, only wooden or synthetic surface is allowed. The court shall be bounded by lines of 5cm width. A line 5cm wide shall be drawn across the center of the playing surface. The axis of the center line divides the playing court into two equal courts measuring 9m X 9m each. This line extends beneath the net from side line to side line. On each court the front zone is limited by the attack line, 3m parallel to the middle of the center line. Beyond the side line both attack lines and front zones are considered to be extended indefinitely. Two lines each 15cm long mark indefinitely the side limits of the service zone at the end of each court. They shall be drawn inside the service zone, 20cm behind and perpendicular to the end line. One is drawn as an extension of each right side line and the other is 3m to the left.
