The sport of lacrosse is governed by US Lacrosse. The US Lacrosse rules regulate the materials allowed and the size and shape of the lacrosse sticks. Different levels of the sport have slightly different regulations, and many of the rules are based on the NCAA collegiate rules. Men's and women's lacrosse have similar stick requirements, with slight variations in size and shape.
The rules state that the stick must be made of rubber, wood, gut, leather, fiberglass, nylon, plastic and any other synthetic material. Only the handle can be made of a composite, metal alloy. Recessed metal screws may be used to affix the head to the handle. The stick also must not have sharp parts or edges.
Head Shape and Size
The head of the stick is roughly triangular and is attached to the handle. The size of the head varies by the level being played, with a 6.5-inch scoop and a 3-inch head being legal in all levels of men's play. The head of a woman's stick varies from 7 to 10 inches wide. Both genders have goalie sticks in which the head is wider than the heads used by the field players.
The pocket of a woman's stick must be strung with leather and/or synthetic strings. Nylon mesh stringing is permitted in men's sticks. The goalie in the women's game is allowed to have a nylon mesh pocket.
NCAA rules require that men's lacrosse sticks (including the head) be from 40 to 42 inches long for offensive players, 52 to 72 inches long for defensive players and 40 to 72 inches long for goalies. For women, the sticks can be 35.5 to 43.25 inches long.
