How to Size Race Skis

FIS Race Ski Sizing Guidelines

FIS regulations change frequently, so it is best to consult with your coach or local ski expert before making a final purchase. Please see the current FIS Specifications for Competition Equipment and USSA/FIS Equipment Rules for specific age and circuit rules.

NON-FIS Race Ski Sizing Guidelines

There are varying opinions on how to best size skis, but the most accurate method to size race skis is based on the athlete's weight. The chart below recommends what size should work best for young athletes using one pair of skis for both events and athletes using Slalom (SL) and Giant Slalom (GS) specific skis. If an older athlete is using one pair for both events, it is best to choose an SL ski that is one size longer than the ideal SL length. A long SL ski will still work for SL and be very serviceable for GS. These are loose guidelines, and you should consult your local coach or ski expert for more specific recommendations.

Sizing Considerations:

  1. Consult FIS, USSA, and other level appropriate regulations.

  2. Racer's ability level and preference - more advanced skiers can generally handle longer length skis which can be more stable at higher speeds.
  3. Growth of the athlete - you may want to consider sizing up a little if you want to get multiple years out of a younger racer's skis, although most coaches agree that skiing on a slightly shorter ski the second year is preferable to skiing on a ski that is too long.
  4. Coach's recommendations.
