How do I know what length skate ski I need?

Skate ski length is determined primarily by your weight, not your height. Each manufacturer provides a weight-to-length chart—follow it closely. Heavier skiers need longer skis for sufficient camber stiffness. As a rough guide: under 60kg typically uses 170–175cm, 60–75kg uses 175–185cm, and over 75kg uses 185–195cm. When between sizes, skilled skiers can go longer for better glide, while newer skaters should choose the shorter option for easier control.
