The Federation of International Lacrosse (FIL) publishes the official indoor lacrosse rulebook. The first indoor edition was published in 2015 and is based on the National Lacrosse League rulebook. There are some variations between the two rule sets. The Canadian Lacrosse Association publishes its own rules for box lacrosse, which provide a third variation of the rules. For fields without boards, US Lacrosse offers a small-sided, small-size field variation of field lacrosse rules.
A typical indoor lacrosse field is 200 feet long by 85 feet wide, the same size as a hockey rink or arena soccer field. The goals are 4'9" wide and 4' tall; the goal line is 12 feet from the ends of the field. Dasher boards are between 3'6" and 4' tall with safety glass on top.
The Federation of International Lacrosse (FIL) publishes official rules for men's and women's field lacrosse. US Lacrosse, in conjunction with the NCAA and NFHS, also publishes outdoor rules for men, women, boys, and girls at the youth, high school, collegiate, and post-collegiate club levels.
An outdoor lacrosse field is 120 yards long by 65 yards wide, the same length as a regulation football field and slightly wider. While the field size is the same in both men's and women's lacrosse, field markings differ slightly. The FIL also publishes diagrams for alternate-sized fields and for a shared lacrosse/field hockey field.
