A size chart · 60 kite surfboards in the atlas

A 75 kg rider wants 24⁠–⁠30 L to learn, 21⁠–⁠25.5 L once riding, 18.8⁠–⁠22.5 L once confident and 16.5⁠–⁠20.3 L as an expert. Litres are a share of your weight in kilos, a ratio that falls as you progress: a fixed margin would go negative for a light rider on boards this small.

These are rules of thumb, the ones shops and sizing guides quote, not any brand’s chart. Where a brand publishes its own rider weights they are below, and they should win.

The rule at each level

  • First sessions: 0.32 to 0.4 L per kg you weigh.
  • Getting there: 0.28 to 0.34 L per kg you weigh.
  • Confident: 0.25 to 0.3 L per kg you weigh.
  • Expert: 0.22 to 0.27 L per kg you weigh.

Your level

  • First sessions: still learning to get up and stay up.
  • Getting there: riding, working on turns and transitions.
  • Confident: linking runs in most conditions.
  • Expert: the smallest board that still gets you going.

Your weight

With your wetsuit on, if you ride in one. Lighter than 50 kg or heavier than 110 kg? The finder works the range out from 35 to 140 kg.

What Fits at 75 kg

Across the 139 sizes listed for kite surfboards in the atlas, the middle 80 % run from 19 to 27 L, and half are under 23 L.

What the Brands Say

13 kite surf sizes from Duotone come with the brand’s own rider-weight range. At the middle of each range, the chart above puts 8 at First sessions, 4 at Getting there and 1 outside every level. A brand knows its own rails and thickness: when its range and the rule disagree, go with the brand.

Beyond the Litres

Kite surfboards look like small surfboards, about 5'4" to 6'4" long with 20–30 L of volume, with a pointed or squashed nose, rails and three or four fins for grip on a wave face. Two outlines appear in the drawings: compact 'noseless' boards, shorter, wider and thicker, which are easy for beginners in waves up to about 1–2 m, and classic surfboard shapes, which hold better in bigger surf. Flat rocker gives speed and planing; more rocker gives tighter turns. They are built stronger than paddle surfboards, with harder foam and reinforced stand zones, because a normal surfboard's deck caves in under kite loads. Rule of thumb: take the higher end of 20–30 L as a beginner, longer for light wind and big waves, shorter for tighter handling.

At the same volume, a wider board is steadier and easier to start on, a narrower one quicker rail to rail; a long board for its width glides and lifts earlier, a short one turns tighter. The finder’s cards say which is which among the boards at your size.

Questions

What size kite surfboard for a beginner?

0.32 to 0.4 L per kg you weigh: 19.2⁠–⁠24 L at 60 kg, 24⁠–⁠30 L at 75 kg and 28.8⁠–⁠36 L at 90 kg. The ranges shrink level by level, so most riders move down a size as they progress.

What size kite surfboard for a 60 kg rider?

19.2⁠–⁠24 L to learn, 16.8⁠–⁠20.4 L once riding, 15⁠–⁠18 L once confident and 13.2⁠–⁠16.2 L as an expert.

What size kite surfboard for a 90 kg rider?

28.8⁠–⁠36 L to learn, 25.2⁠–⁠30.6 L once riding, 22.5⁠–⁠27 L once confident and 19.8⁠–⁠24.3 L as an expert.

Should I go by the brand’s size chart?

When it has one, yes: it knows its own rails and thickness. 13 kite surf sizes in the atlas come with one, listed above.

Is volume the only number that matters?

No: width and length change how a board rides at the same volume (above), and thickness and rails change how it floats. Start from the volume, then pick the shape.
