Find the right ski length based on your height, weight, and skiing ability level.
When standing, ski tips should reach between your chin and forehead.
Ski length recommendations start with your height as a baseline, then adjust based on ability level, weight, terrain preferences, and ski type. The calculator uses industry-standard formulas that ski shops and manufacturers rely on.
The starting point is a percentage of your height:
These percentages translate to physical landmarks on your body—chin level for beginners, nose for intermediates, and forehead to above-head for experts.
Body weight significantly affects how skis perform. The calculator adjusts length based on your weight relative to average for your height:
Different terrain demands different ski characteristics:
| Terrain | Adjustment | Reason |
|---|---|---|
| Groomed/Carving | -5 to -10 cm | Quick edge-to-edge transitions |
| All-Mountain | No change | Balanced performance |
| Powder/Big Mountain | +5 to +10 cm | Surface area for flotation |
| Park/Freestyle | -5 to -10 cm | Easier spins, switch landings |
| Moguls | -5 to -10 cm | Tight turn radius needed |
Designed for groomed runs with a narrow waist (65-80mm) and pronounced sidecut. The hourglass shape creates a natural arc when the ski is edged. Shorter lengths (relative to height) allow quicker turn initiation.
Best for: Resort skiing, hard-packed snow, speed on groomers
The versatile middle ground with moderate waist widths (80-100mm). Can handle groomers, light powder, and variable conditions. Standard length recommendations apply.
Best for: Skiers who want one pair for everything
Wide underfoot (100-120mm+) with early rise tips and often tails. The extra surface area keeps you floating on soft snow. Go 5-10cm longer than your all-mountain length.
Best for: Deep days, backcountry, soft snow conditions
Twin-tip design for landing switch. Softer flex for pressing and buttering. Shorter lengths make rotations easier and reduce swing weight.
Best for: Terrain parks, jumps, rails, halfpipe
Stiff construction for maximum power transfer. Giant slalom skis run longer (185-195cm for men), slalom skis much shorter (155-165cm). Specific regulations govern competition lengths.
Best for: Racing, high-speed carving, aggressive skiing

Weight affects ski performance more than many people realize:
Heavier Skiers Need Longer Skis Because:
Lighter Skiers Benefit From Shorter Skis Because:
Your personal style affects ideal length:
Waist width (the narrowest point under your boot) interacts with length:
A 180cm ski with 100mm waist has more surface area than a 180cm ski with 70mm waist. This means wide skis provide flotation at shorter lengths. Many powder ski manufacturers specifically recommend sizing down from your all-mountain length.
Modern skis use different bend patterns that affect effective length:
The ski arcs upward in the middle, touching snow at tip and tail when unweighted. Full edge contact when pressured. These skis perform closest to their measured length.
The tip curves up earlier than traditional skis. Reduces effective edge contact by 5-10cm. Makes turn initiation easier and improves float. Size these normally or slightly longer.
Both tip and tail curve up, with a flat or slightly raised middle section. Significantly reduced effective edge. Great for powder but can feel shorter on groomers. Often sized longer to compensate.
Hybrid profile with camber underfoot and rocker at both ends. Popular for all-mountain skis. Size normally—the camber provides grip while rocker aids turn entry/exit.

Women's skis typically run 5-10cm shorter than men's for the same height due to differences in center of mass and typical weight distributions.

Kids' ski sizing follows different rules than adults:
| Age | Typical Height | Ski Length Range |
|---|---|---|
| 3-4 | 95-105cm | 70-90cm |
| 5-6 | 105-120cm | 90-110cm |
| 7-8 | 120-135cm | 100-125cm |
| 9-10 | 135-145cm | 115-135cm |
| 11-12 | 145-160cm | 125-150cm |
| 13+ | 155cm+ | Transition to adult sizing |
Go Shorter: Children should generally ski shorter relative to height than adults. Shorter skis are easier to control and build confidence.
Size for Current Ability: Don't buy skis to "grow into"—oversized skis are dangerous and frustrating. Replace skis as skills and size develop.
The Chin-to-Nose Rule: For most kids, skis should reach between chin and nose when stood upright. Only advancing young racers should go longer.
Weight Matters More: Light children should go shorter. A small 7-year-old might need skis suited for a 5-6 year old.
The biggest error, especially among men. Longer isn't better—it's just harder to ski. Unless you're an expert charging steep terrain at high speed, err toward the shorter end of recommendations.
Two people who are 5'10" might need very different ski lengths if one weighs 140 lbs and the other 200 lbs. Always factor in weight.
Skiing advanced-length skis when you're intermediate doesn't make you a better skier—it makes you a worse one. Proper-sized equipment helps skills develop faster.
If you ski varied terrain, consider a quiver. Your 100mm all-mountain ski won't perform like a dedicated carver or pow ski. Different tools for different jobs.
A 175cm powder ski does not ski like a 175cm carving ski. Factor in waist width, rocker profile, and intended use when sizing.
Children grow fast, so parents buy long skis to save money. This is counterproductive and potentially dangerous. Kids on proper-sized skis progress faster and have more fun.
If you're between two sizes:
Generally yes, by about 5-10cm. Women typically have a lower center of mass and less upper body mass. Women's skis are also designed with different flex patterns and binding mount points. However, athletic women who ski aggressively may prefer unisex or men's lengths.
You can, but you'll make compromises. A mid-length all-mountain ski works for everything but excels at nothing. Serious skiers often own 2-3 pairs sized differently for specific purposes.
Consider new lengths when:
Directly, no. However, boot sole length affects binding position, which can impact ski balance. This is set when the bindings are mounted and doesn't change your ski length needs.
Ski manufacturers make skis in fixed increments (usually 3-7cm apart). Round to the nearest available size. If exactly between options, see the "sizing up or down" guidance above.
At elite levels, yes—race skis are longer for maximum speed. For recreational skiers, properly sized skis allow better technique, which is more important than length for speed. An intermediate on proper 170cm skis will likely outperform the same skier struggling on 185cm skis.
The best way to find your ideal ski length is to demo different options. Many ski shops and resorts offer demo programs where you can try multiple skis in real conditions.
Benefits of demoing:
Most demo fees apply toward purchase if you buy the skis you tested. It's worth the investment to ensure you get skis that match your abilities and style.
Modern skis are more forgiving and versatile than ever. Advances in rocker profiles, lightweight materials, and construction have made it easier to ski a slightly "wrong" length without major performance penalties.
That said, properly sized skis still make a noticeable difference. You'll progress faster, have more fun, and ski more safely on equipment matched to your body and abilities. Use this calculator as a starting point, adjust based on your personal factors, and demo when possible.
