> The ski size calculator recommends a ski length from your height, adjusted for your build (weight), ability, skiing style and the type of skiing you do, with a ±3 cm range.

## Inputs

- Height (cm, m, ft, in)
- Weight (kg, lb)
- Ability
- Style
- Type of skiing

## Results

- Build adjustment
- Recommended ski length
- Range from
- Range to

## Formula

```
Length (cm) = height − ability (beginner 17, intermediate 13, advanced 9) + style (−2, 0, +2) + use (park −3.5 … racing +7.5) + build ((BMI − 22) cm, max ±5)
```

## Explanation

Shorter skis turn easily and suit beginners; longer skis are more stable at speed and float in powder. Most adults ride skis somewhere between chin and the top of the head.

### What each result means

- **Build adjustment** = max(-5, min(5, [Weight]÷[Height]^2 - 22))
- **Recommended ski length** = [Height]×100 - [Ability] + [Style] + [Type of skiing] + [Build adjustment]
- **Range from** = [Height]×100 - [Ability] + [Style] + [Type of skiing] + [Build adjustment] - 3
- **Range to** = [Height]×100 - [Ability] + [Style] + [Type of skiing] + [Build adjustment] + 3

### Example values

How the main result changes when **Height** changes and everything else stays at the example values above:

## Worked example

Inputs — Height: 175 cm; Weight: 75 kg; Ability: Intermediate; Style: Normal; Type of skiing: All-mountain.

Results — Build adjustment = 2.5 cm; **Recommended ski length = 166 cm**; Range from = 163 cm; Range to = 169 cm.

## Key terms

- **Rocker**: Ski tip/tail that rises early, making the ski feel shorter.

## FAQ

**How long should beginner skis be?**
Roughly chin height.

**Do heavier skiers need longer skis?**
Slightly – longer skis spread the load and are more stable.

**Are rocker skis different?**
Rockered skis ski shorter, so you can go 5 cm longer.

**What about kids?**
Children's skis are usually chest to nose height.
