Kiteboarding Calculator

Estimate the kite size for your weight and the wind.

Recommended kite size 12

Formula: size ≈ 12 × (18 ÷ wind) × (weight ÷ 75)

Step-by-step with your numbers:

1. Values used:

2. Rider weight = 75

3. Wind speed = 18 kn

5. Recommended kite size = 12

Did we solve your problem today?

Kite size scales up with rider weight and down with wind strength.

The math behind it

A practical guide: a 75 kg rider uses about a 12 m² kite in 18 knots, scaling with weight and inversely with wind.

75 kg in 18 knots → about 12 m².

Should I size up or down?

When unsure, size down — an over-powered kite is harder and riskier to control.
