Hockey stick flex calculator

Stick flex starts from body weight: Start with a flex number a little less than half your body weight in pounds. A higher number is stiffer, a lower number is whippier. Source: Bauer stick buying guide

Start near half your weight in pounds, then adjust for your shot and strength. Kids need softer flexes. Source: Warrior stick buying guide

Cutting a stick makes it stiffer and an extension makes it softer, so pick the flex for the length you will actually play. Flex is partly preference: a player who shoots more wristers often goes softer.
