The old NCAA specifications are:
- 140g - 147g
- 62.7 mm - 64.7 mm
- From 1,800 height 1,092 – 1292 mm (70% rebound from falling point)
- Rubber content
The new NCAA year 2000 specs states: "Section 17. The ball shall be white, yellow or orange solid rubber between 7 3/4 and 8 inches in circumference, between 5 and 5 1/2 ounces in weight and when dropped from a height of 72 inches upon concrete floor, shall bounce 43 to 51 inches at a temperature of 65 degrees fahrenheit."
Beginning with the 2014 season, all three governing bodies for lacrosse in the United States (US Lacrosse, NFHS, NCAA) have mandated that only balls meeting the NOCSAE ball standard may be used for competition. Balls must be emblazoned with the words "Meets NOCSAE Standard" in order to be deemed legal for play by game officials.
The four main manufacturers of lacrosse balls are East Coast Dyes, Warrior, STX, Brine and Signature Lacrosse. Warrior is the exclusive supplier of lacrosse balls to Major League Lacrosse with their orange "justin diamond" ball, Brine is the official supplier of lacrosse balls to the NCAA and STX is commonly used in high school and Jr (little league) lacrosse. The National Lacrosse League uses Under Armour balls meeting NCAA standards. In Canadian box lacrosse all balls must be CLA approved. The main brand in which Canadian box lacrosse balls are used is Gait. East Coast Dyes provides the Mint, a lacrosse ball that does not become hard and slippery over time and also meets the NOCSAE standards calling for a softer ball, which will go into effect no early than June 2017.
