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.
Piste
Redster G
Advanced and expert skiers as well as heavier people will find the right ski length by adding 5 to 10 centimeters to the measurement to the top of the head.
Shorter and lighter skiers may go for a ski length that equals their height.
Redster S
The length of a slalom ski should be well below the top of your head. Common lengths are between 165 and 170 centimeters for men, and between 150 and 165 centimeters for women.
Redster X & Q, all Cloud skis
Advanced and expert skiers should go for a ski length that equals their height; those of more than average weight and aggressive skiers may want to add up to 5 centimeters.
Less experienced and lightweight skiers should subtract 5 to 10 centimeters from the measurement to the top of the head.
