Last updated: 2026-10-30

> The kiteboarding calculator recommends a kite size from your weight, the wind speed, kite type and board – or the wind range for a kite you already own.

## Inputs

- Find
- Rider weight (kg, lb)
- Wind speed (kn, km/h, mph, m/s)
- Kite size (m²)
- Board
- Kite type

## Results

- Wind (knots)
- Recommended kite size
- Ideal wind for your kite
- Usable from about
- up to about

## Formula

```
Kite size (m²) = weight (kg) × 2.2 ÷ wind (knots) × board factor · Ideal wind = weight × 2.2 ÷ size
```

## Explanation

Choosing the right kite keeps you safe and having fun: too big and you're overpowered; too small and you sink. Heavier riders need bigger kites, stronger wind smaller ones.

### How to use the Kiteboarding Kite Size Calculator

- **Find**
- **Rider weight**
- **Wind speed**
- **Kite size (m²)**
- **Board**
- **Kite type**

Always take lessons and check local conditions; these are rough guidelines. Everything is calculated in your browser.

### How it works

Choose what to find, enter your weight and the wind speed or kite size, and your board type.

### Tips

- Check local conditions and safety rules before going out.
- Start with conservative equipment choices and adjust with experience.
- Every field has its own unit menu.
- Everything is calculated in your browser.

### Common mistakes to avoid

- Using estimates instead of a proper check in the water.
- Mixing feet and metres, or knots and km/h.
- Overestimating your skill in strong wind.

### Inputs explained

### What each result means

- **Wind (knots)** = [Wind speed]÷0.514444
- **Recommended kite size** = [Rider weight]×2.2÷([Wind speed]÷0.514444)×[Board]×[Kite type]
- **Ideal wind for your kite** = [Rider weight]×2.2×[Board]×[Kite type]÷[Kite size (m²)]
- **Usable from about** = [Rider weight]×2.2×[Board]×[Kite type]÷[Kite size (m²)]×0.8
- **up to about** = [Rider weight]×2.2×[Board]×[Kite type]÷[Kite size (m²)]×1.3

### Example values

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

## Worked example

Inputs — Find: Kite size for the wind; Rider weight: 75 kg; Wind speed: 18 kn; Board: Twin-tip; Kite type: Inflatable (LEI / bow / C).

Results — Wind (knots) = 18 kn; **Recommended kite size = 9.2 m²**.

## Key terms

- **LEI**: Leading-edge inflatable kite.

## FAQ

**What size kite for a beginner?**
Usually 9–12 m² for an average adult in 15–20 knots.

**How much wind do I need?**
Most riders need at least 12 knots; hydrofoils work in 8–10.

**Should I buy a bigger kite?**
Start with a mid-size kite for your local average wind.

**Is kiteboarding dangerous?**
It can be – take lessons from a certified school.
