The Playing Court: The court measures 20 meters (65' 7") by 40 meters (131' 3"). The goal area line, or 6-meter line (19' 8"), is the most important line. No one except the goalie is allowed to stand in the goal area. The goal opening is 2 meters by 3 meters. Players may jump into the area if the ball is released before landing in the area.
The Ball: Team handball is played with a 32-panel leather ball. For women, the ball is 54 to 56 centimeters and 325 to 400 grams (ball size 2). For men, it is 58 to 60 centimeters and 425 to 475 grams (ball size 3).
Number of Players: There are seven players on each team (six court players and one goalie). A maximum of 12 players may dress and participate in a game for each team. Substitutes may enter the game at any time through own substitution area as long as the player they are replacing has left the court.
Uniform of the Players: Uniform shirts and shorts are the same color. The goalkeeper must wear a different color shirt from teammates and opponents. No jewelry is allowed.
Referees: There are two referees, a court referee and a goal line referee. Referees have complete authority: Their decisions are final. The referees are assisted by a timer and a scorer.
Duration of the Game: For players 18 years and over, the game consists of 2, 30-minute halves with 10-minute half-time. This is running time except for injury or one team time-out per half. The teams change benches at half-time. The game ends in a tie unless the game demands a winner. (Tournament rules dictate that a winner must be determined.) Overtime consists of 2, 5-minute periods.
Passive Play: It is illegal to keep the ball in a team's possession without making a recognizable attempt to attack and to try to score. In other words, a team cannot stall (free-throw awarded to the other team). Throw-Off: A throw-off is taken by the team that wins the coin toss and chooses to start the game with the ball. Each team must be in its own half of the court with the defense 3 meters away from the ball. Following a whistle, the ball is passed from center court to a teammate and play begins. Throw-off is repeated after every goal scored and after half-time.
Scoring: A goal is scored when the entire ball crosses the goal line inside the goal. A goal may be scored from any throw (free-throw, throw-in, throw-off, goal-throw).
