Both of these answer a question people otherwise guess at in a shop: what volume, what size. Each result links straight through to the guide that explains it.
Ideal volume in litres from your weight, level and the waves you actually surf.

Open the Kitesurf tool arrow_forwardEvery calculator on this site is a starting point, not a verdict. They work from the figures published in our own buying guides, so a tool and a guide never tell you two different things — a problem that is genuinely common elsewhere, where the same site will give you three different formulas on three pages.
Where a physical check exists, trust it over the arithmetic. The wrist check beats any paddle-length chart. Standing on a demo board beats any volume table. Use the number to walk into the conversation knowing roughly what you need, then let the water confirm it.
Paddle board volume, SUP paddle length, wetsuit thickness, windsurf sail size and wing foil size all have calculators of their own on our US tools page. They default to Fahrenheit, pounds and miles per hour, but every one of them takes metric from the same dropdown, so they work perfectly well from here.
