Value in knots. 1 knot = 1.85 km/h (about 1.15 mph). Ideal kitesurfing wind: 12–25 knots.
| Wind (knots) | Wind (km/h) | 60 kg | 75 kg | 90 kg |
|---|---|---|---|---|
| 10–12 | 18–22 | 14–16 m² | 16–18 m² | 18–21 m² |
| 12–15 | 22–28 | 12–14 m² | 14–16 m² | 16–18 m² |
| 15–20 | 28–37 | 10–12 m² | 11–13 m² | 13–15 m² |
| 20–25 | 37–46 | 8–10 m² | 9–11 m² | 11–13 m² |
| 25–30 | 46–56 | 7–9 m² | 8–10 m² | 9–11 m² |
| 30+ | 56+ | 5–7 m² | 6–8 m² | 7–9 m² |
These figures are for an intermediate level. Beginners should go one size up, experts one size down, depending on style.
A kite's size (measured in m²) determines how much power it generates. The larger the surface area, the harder it pulls: great in light wind, dangerous in strong wind. Two main factors guide the choice: your weight and the wind strength.
For a 75 kg kiter in 18 knots of wind, a kite of 12 to 14 m² is generally a good fit. Every extra 10 kg of bodyweight needs roughly 1–2 m² more. Every extra 5 knots of wind lets you drop about 2 m².
Beginners are better off with a slightly larger kite, giving more power in reserve for lighter wind. Experts often prefer smaller kites for sharper feel and less physical effort.
