How to determine your correct ski length
When choosing the right ski length, there are a couple of factors you need to take into consideration. The most important are your height, weight, ability level, and the type of skiing you plan to do.
As a general guideline, choose a ski that reaches somewhere between your chin and the top of your head (or, for some skis, slightly above your head). A shorter ski makes shorter turns and is typically easier to maneuver at lower speeds, while a longer ski will have a longer turn radius and generally offers greater stability and confidence at higher speeds.
Taller, heavier, and more advanced skiers often prefer slightly longer skis because they have more leverage over the ski. Shorter, lighter people and less-experienced skiers will usually feel more comfortable with the agility of a shorter ski.
The recommendations below provide a general starting point for choosing the right ski length within Atomic’s ski range. Individual preferences, ski models, and intended terrain may influence the ideal length.
Kids
For children aged 2 to 5 years, select skis that reach just below the child’s chin. For children aged 6 to 12 years, the ski tip should come to the center of the child’s forehead. Depending on the child’s height and skill level, a shorter or longer ski may be more suitable, with beginners typically benefiting from shorter skis.
