A volleyball court is 18 m (59 ft) long and 9 m (29.5 ft) wide, divided into 9 m ◊ 9 m halves by a one-meter (40-inch) wide net. The top of the net is 2.43 m (7 ft 11 5/8 in) above the center of the court for men''s competition, and 2.24 m (7 ft 4 1/8 in) for women''s competition, varied for veterans and junior competitions.
A line 3 m (9.84 ft) from and parallel to the net is considered the "attack line". This "3 meter" (or "10 foot") line divides the court into "back row" and "front row" areas (also back court and front court). These are in turn divided into 3 areas each: these are numbered as follows, starting from area "1", which is the position of the serving player:
After a team gains the serve (also known as siding out), its members must rotate in a clockwise direction, with the player previously in area "2" moving to area "1" and so on, with the player from area "1" moving to area "6".
The team courts are surrounded by an area called the free zone which is a minimum of 3 meters wide and which the players may enter and play within after the service of the ball. All lines denoting the boundaries of the team court and the attack zone are drawn or painted within the dimensions of the area and are therefore a part of the court or zone. If a ball comes in contact with the line, the ball is considered to be "in". An antenna is placed on each side of the net perpendicular to the sideline and is a vertical extension of the side boundary of the court. A ball passing over the net must pass completely between the antennae (or their theoretical extensions to the ceiling) without contacting them.
