⛷️ Ski Size Calculator
Find the right ski length with adjustments for ability, terrain, and ski style—whether you’re carving groomers or floating through powder.
Convert from feet/inches: multiply by 2.54.
For pounds, divide by 2.205.

How to Use This Calculator
Enter height and weight
Body dimensions set the baseline length range. Height strongly influences ski choice.
Select ability level
Beginner skiers benefit from shorter skis; advanced riders can size up for stability.
Choose terrain and ski style
Powder and freeride skis run longer for float; park and carving skis are shorter for maneuverability.
Review recommended length
Use the range to test skis in-store or demo days. Fine-tune based on stiffness and rocker profile.
Formula
Recommended Length = (Height × 0.94) + Ability Adjustment + Terrain Adjustment + Style Adjustment + Weight Adjustment
Adjustments vary ±3–8 cm depending on the factors selected. Final range adds ±5 cm to accommodate personal preference and specific ski designs (rocker vs. camber).
This heuristic mirrors common shop fitting practices. Always test skis when possible—flex, rocker profile, and specific model design can influence effective length.
Ski Selection Tips
Ski length works alongside width, flex, and rocker profile. Match the recommendation with the specific ski model’s manufacturer guidance.
Adjust for ski design
- Full rocker skis feel shorter—size up 3–5 cm compared to cambered skis.
- Stiffer skis provide more stability; softer skis feel more forgiving at slightly longer lengths.
- Mounting position (center vs. traditional) influences effective length in park skis.
When to size down
- Narrow tree runs or teaching situations requiring tight control.
- Skiers still developing confidence linking turns on steeper pitches.
When to size up
- High-speed groomer skiing or racing focus.
- Regular deep powder days requiring extra float.
- Taller/heavier riders seeking stability in chopped snow.
Frequently Asked Questions
How do rocker and camber affect length choice?
Rockered tips shorten the effective edge—size 3–5 cm longer to maintain edge grip compared to cambered skis.
Should beginners always choose shorter skis?
Yes, within reason. Aim for chin height with forgiving flex; upgrade length as confidence grows.
Do rental shops use similar formulas?
Rental and specialty shops rely on body dimensions, ability, and terrain—this calculator mirrors those heuristics.
Can I convert to inches?
Divide centimeter recommendations by 2.54 to get inches, or rely on ski manufacturer size charts.
Does boot size matter?
Boot size affects stance width and leverage but has minimal impact on ski length selection.
