Laws of the Game:The Court
The playing area includes the court and space surrounding it. Areas include: Free zone, boundary lines (sidelines and end lines which make up the dimensions of the court), centerline, attack line, front zone, service zone, and substitution zone. Indoor and outdoor courts are 59' x 29' 6", or 18 x 9 meters.Lines and Zones
The centerline, the line that divides the court in half, runs the length of the net from one sideline to the other. Lines on the court are 2 inches wide, or 5 cm. The indoor court includes an attack area. The attack area line lies on either side of the court and extends from one sideline to the other and is placed 9 feet 10 inches, or 3 meters, from the centerline. All lines are two inches wide. The front zone lies between the centerline and the attack line and beyond the sidelines to the end of the free zone. The area behind the end line that extends from one sideline to the other designates the service zone, which is 29 feet 6 inches wide, or 9 meters, and extends to the end of the free zone. The substitution zone runs from attack lines up to the scorer's table.The Net
The USAV acceptable height of the indoor/outdoor net for men or co-ed mixed sizes is 7'11-5/8", or 2.43 meters. For women, the net height is 7'4-1/8". For players 14 years old and younger, the net height should be 7'4-1/8" or 2.24 meters. The height of the volleyball net is measured at the center, and should be exactly the same measurement as the two sidelines and cannot be more than 2 cm higher than the official measurement.The Ball
An official volleyball weighs between 9 and 10 ounces, with air pressure being anywhere from 4.5 to 6 pounds.The Game
Before a match begins, the referee calls a short meeting in which he goes over any rules, including substitution and timeout procedures, and conducts a coin toss to determine the first server.The Serve
The server is the player in the right back position and who must be standing behind the end line while executing the serve. Servers are allowed only one toss or release of the ball, many of which like to bounce or toss the ball a few times before serving. However a toss or release doesn't count until it is done with intent to serve.
