Ski Length Calculator

Ski length affects stability, maneuverability, and how the ski performs in different conditions. The right length depends on your height, weight, ability, and skiing style.

General starting point: For an average adult intermediate skier, the ski should reach somewhere between your nose and the top of your head when stood on end. This translates roughly to height minus 5-15 cm (2-6 inches).

You will see that rule written as chin to forehead, and the two do not describe the same ski. An adult head is about 23 cm from crown to chin, so your chin sits at your height minus 23, which is a good deal shorter than anything the numbers below produce. Whichever wording you have met, measure against the centimetres rather than the landmark: minus 5 to minus 15 is the range this page works in, and that lands around your nose at the short end and the top of your head at the long one.

Adjustments by ability:

• Beginner: Subtract 10-15 cm from height. Shorter skis are easier to turn and control.
• Intermediate: Subtract 5-10 cm from height. A balanced length for most conditions.
• Advanced/Expert: Subtract 0-5 cm from height (or go height-matched). Longer skis are more stable at speed.

Adjustments by style:

• All-mountain: Standard recommendations above
• Park/Freestyle: Subtract an additional 5 cm. Shorter skis are more maneuverable for tricks.
• Powder/Big Mountain: Add 5-10 cm. Longer skis float better in deep snow.
• Carving/Groomed runs: Subtract 5 cm. Shorter skis initiate turns more easily on hardpack.

Weight considerations:

• If you are heavier than average for your height, go 2-5 cm longer for added stability.
• If you are lighter than average, go 2-5 cm shorter for easier turn initiation.

Ski width (waist width) guidelines:

• Under 80mm: Groomed/carving focused
• 80-100mm: All-mountain versatile
• 100-120mm: Powder-oriented
• Over 120mm: Deep powder specific

For children: Skis should generally reach between the child’s chest and chin. Never size up too much for kids to “grow into”. Oversized skis are genuinely dangerous, not just awkward, because a child cannot pivot them out of a fall line.

Why this page asks for height and the snowboard one asks for weight. It is not an oversight on either. A ski is sized off height because it works as a lever against the snow along its length, and the two ends of that lever are set by how tall you are. A snowboard is sized off weight because it works by flexing underfoot, and what it flexes against is your mass, so the snowboard size calculator leads with weight and treats height only as a sanity check. Anyone who rides both will notice the two pages ask completely different questions, and that is the reason.
