The goals in box lacrosse are much smaller than field lacrosse, traditionally 4 feet (1.2 m) wide by 4 feet (1.2 m) tall in box, and 4.6 feet (1.4 m) wide by 4 feet (1.2 m) tall in the NLL. Also, the goaltender wears much more protective padding, including a massive chest protector and armguard combination known as “uppers”, large shin guards known as leg pads (both of which must follow strict measurement guidelines), and ice hockey-style masks or lacrosse helmets. Also, at the professional level, box lacrosse goaltenders often use traditional wooden sticks outside of the NLL, which does not allow wooden sticks. This makes Box Lacrosse faster and rougher than the traditional Field Lacrosse.
The style of the game is quick, accelerated by the close confines of the floor and a shot clock. The shot clock requires the attacking team to take a shot on goal within 30 seconds of gaining possession of the ball. In addition, players must advance the ball from their own defensive end to the offensive side of the floor within 10 seconds.
Box lacrosse is also a much more physical game. Since cross checking is legal in box lacrosse, players wear rib pads in addition to the shoulder and elbow pads that field lacrosse players wear. Box lacrosse players wear a different type of helmet as well, a hockey helmet with a box lacrosse cage.
For most penalties, the offending player is sent to the penalty box and his team has to play without him (thus lacking one player) for a short amount of time. Most penalties last for two minutes, unless a five-minute major penalty has been assessed. What separates box lacrosse (and ice hockey) from other sports is that at the top levels of professional and junior lacrosse, a five-minute major penalty is given and the players are not ejected for participating in a fight.
