Ski Length Calculator
Seven ski-fitting tools in one: this ski length calculator by height and weight sizes adult skis from height, weight, skill and ski type; a ski-type adjuster; a kids ski size calculator; a ski pole length calculator; a mondo size calculator and ski boot size converter; a din calculator built on the ski binding DIN chart; and an effective edge vs ski length explainer. 100% client-side — nothing leaves your browser.
Ski length from height, weight & skill
The chin-to-nose rule, refined: beginners size toward the chin (height − 10 cm), intermediates toward the nose (height − 5 cm), advanced skiers up to full height — then ±5 cm for weight.
Ski-type adjuster
Know your all-mountain length? Convert it: powder runs about 5 cm longer for float, carving about 5 cm shorter for quick turns, touring stays close to all-mountain.
Kids ski size calculator
Junior skis should reach between your child's chest and nose. Beginners start 20 cm under height; experienced young skiers 10 cm under — adjusted for weight.
Ski pole length calculator
The alpine rule of thumb: pole length = height × 0.70, rounded to the nearest 5 cm. Park and mogul skiers often go 5 cm shorter; powder and touring skiers 5 cm longer.
Boot mondo converter
Mondo point is your foot length in centimeters — the one size that means the same thing on every brand. This mondo size calculator works as a ski boot size converter: enter any system to convert mondo to US size, UK or EU, and see the full row.
Binding DIN reference
This din calculator follows the ski binding DIN chart in ISO 11088, turning your weight, height, age, skier type and boot sole length into one release number. This is an explainer, not a setting.
Rocker, camber & effective edge
Stated length is measured tip to tail, but only the snow-contact patch — the effective edge — actually grips. Rocker lifts the ends off the snow and shortens it.
How the numbers are computed
- Ski length: all-mountain baseline of height − 10 / − 5 / + 0 cm for beginner / intermediate / advanced (retailer size-chart method), ±5 cm when your weight is 10+ kg off the reference for your height, +5 powder / −5 carving / −5 touring, rounded to sold 5 cm sizes.
- Kids: height − 20 cm (beginner) or − 10 cm (experienced), ±5 cm for weight, clamped to the 70–150 cm junior range.
- Poles: height × 0.70, rounded to 5 cm (−5 park, +5 powder).
- Mondo: exact chart lookup; US women's runs one size above men's on the same shell; EU varies slightly by brand.
- DIN: ISO 11088 reference table (skier code from weight/height, type and age adjustments, boot-sole column). Reference only — a certified shop sets and tests bindings.
- Effective edge: rough estimate from rocker profile (full camber ≈ 85%, tip rocker ≈ 80%, tip+tail ≈ 75%, full rocker ≈ 65% of stated length).
Frequently asked questions
What size skis do I need?
Stand a ski upright next to you: the classic rule is it should reach somewhere between your chin and your nose. This ski length calculator by height and weight refines the classic ski size chart with your skill level. Example: a 178 cm, 80 kg intermediate skier on all-mountain skis gets 175 cm (a sensible range is 170–180 cm). Beginners go shorter toward the chin; advanced skiers go longer toward the nose. This ski sizing guide covers all seven modes below.
What is the right ski length for beginners?
Yes. Shorter skis are easier to turn and less tiring, which is why beginners size toward the chin (about height minus 10 cm). For example, a 178 cm tall beginner lands around 170 cm, while the same skier as an intermediate lands around 175 cm. As your technique improves you can size up for more stability at speed.
How does weight affect ski length?
Heavier skiers need more ski to stay stable; lighter skiers turn easier on shorter skis. This calculator adds 5 cm if you are 10 kg or more above the reference weight for your height, and subtracts 5 cm if you are 10 kg or more below it. For example, a 178 cm skier at 80 kg gets no adjustment, but at 95 kg the recommendation moves up to 180 cm. The adjustment sits on top of the ski length by height baseline.
What ski length works for powder versus carving skis?
Powder skis run longer for float (about 5 cm above your all-mountain length), while carving skis run shorter for quick edge-to-edge turns (about 5 cm below). Using the 178 cm intermediate example: all-mountain 175 cm, powder 180 cm, carving 170 cm. So powder ski length lands about 5 cm above all-mountain, carving ski length about 5 cm below, and touring ski length stays close to all-mountain. Rockered skis also ski shorter than their stated length, so sizing up compensates.
What size skis for kids?
Junior skis should reach between your child's chest and nose — never taller than they are. Weight matters more than age: heavier kids size up. The junior ski size chart logic here starts beginners 20 cm under height (experienced 10 cm under), then adjusts for weight. Example: a 130 cm, 28 kg beginner gets 110 cm skis. If the result falls outside the 70–150 cm junior range, a shop should confirm the fit in person.
How long should my ski poles be?
The ski pole length rule for alpine skiing is your height times 0.70, rounded to the nearest 5 cm — the same basis as a classic ski pole size chart. A 178 cm skier needs 125 cm poles (about 49 inches). Check the fit with the upside-down test: flip the pole, grip below the basket, and your elbow should form a 90-degree angle.
What is mondo sizing for ski boots?
Mondo point is simply your foot length in centimeters, and it is the same across every brand — which is why boot fitters trust it more than US, UK, or EU sizes. The ski boot mondo chart above converts mondo to US size and back: for example, a US men's 9 converts to mondo 27.0 (UK 8, EU about 42). Note that EU conversions vary slightly between brands; the mondo number is the exact one.
What DIN should I use?
This din calculator follows the ski binding DIN chart in ISO 11088, using your weight, height, age, skier type, and boot sole length — not guesswork. Example: an 80 kg, 178 cm, 30-year-old Type 2 skier with 315 mm boots charts at DIN 6.5 (reference range 6–7). This is a reference only: a certified shop must set and test your bindings on a calibrated jig. Never set bindings yourself from a chart.
Effective edge vs ski length — what is the difference?
Stated length is measured tip to tail, but only the cambered middle touches snow — that contact patch is the effective edge, and it is what actually grips. Rocker lifts the tips (and tails) off the snow, shortening the edge. Estimate: a 175 cm ski with tip-and-tail rocker has roughly 131 cm of effective edge. These are rough estimates; manufacturers rarely publish edge length.
Ski rocker vs camber explained: do rockered skis need to be longer?
Usually yes. Because rocker shortens the effective edge, a heavily rockered ski skis shorter than its stated length — so sizing up about 5 cm keeps stability comparable to a cambered ski. That is also why powder skis, which are almost always rockered, are sized longer: float comes from the full length, grip from the shorter edge. When learning how to choose ski length, treat rocker as a five-centimeter nudge above the chart result.
