Avoid buying skis to grow into: skis that are too long make learning harder. Junior lease programs and swaps are a good way to keep up with growth.
How the ski size calculator works
SkiSizeCalc converts your height to centimetres and starts from it. For alpine skis it subtracts 15 cm for beginners (skis to about the chin), 8 cm for intermediates (about the nose), 3 cm for advanced skiers and adds 2 cm for experts. Carving skis are 5 cm shorter, park skis 3 cm shorter and freeride or powder skis 5 cm longer than all-mountain. If you are at least 10 kg (22 lb) lighter or heavier than a typical weight for your height, the length moves 5 cm. Cross-country classic skis are height + 20 cm and skate skis height + 10 cm. Poles are height × 0.68 for alpine, × 0.84 for classic and × 0.89 for skate, rounded to the nearest 5 cm.

Cross-country ski and pole lengths
| Height | Classic skis | Classic poles | Skate skis | Skate poles |
|---|---|---|---|---|
| 150 cm (4′11″) | 170 cm | 125 cm | 160 cm | 135 cm |
| 160 cm (5′3″) | 180 cm | 135 cm | 170 cm | 140 cm |
| 170 cm (5′7″) | 190 cm | 145 cm | 180 cm | 150 cm |
| 180 cm (5′11″) | 200 cm | 150 cm | 190 cm | 160 cm |
| 190 cm (6′3″) | 210 cm | 160 cm | 200 cm | 170 cm |
Lengths are a starting point. Ski shape (rocker, sidecut, waist width), the maker’s size chart and your terrain all matter; a ski shop or demo day is the best final check. Bindings must be adjusted (DIN setting) by a qualified technician.
Frequently asked questions
What size skis for a 7 year old?
Most 7 year olds are about 120 cm tall, so roughly 100–110 cm skis for a beginner.
Should kids skis be chin or nose height?
Chin height for beginners and cautious skiers, nose height for confident kids who ski the whole mountain.
Do young kids need poles?
Usually not until they can turn and stop well, often around age 6 to 8.
Is SkiSizeCalc free?
Yes, with no sign-up or ads, and your numbers stay in your browser.
Are the results exact?
No. They are a starting point. Check the maker’s size chart and, if you can, demo skis before you buy.
