Wing Foil Size Chart: What Size Wing Do You Need by Weight and Wind?

Hand wings are sized in square meters, and the decision that matters most is driven by two numbers: your weight and your local wind. For a typical 15–20 knot coastal breeze, the starting points are tight now across published guides — under 70kg → 4–5m, 70–90kg → 5–6m, over 90kg → 6–7m. Most adults end up starting on a 5m or 6m.

Wind shifts everything. Learning in light, gusty inland air pushes you a size or two up — an 8m wing for sub-15 knot sessions is a legit tool for lake riders. A steady coastal sea breeze lets you hold a smaller wing that's easier to keep out of the water during transitions. The golden rule for a first wing: size up rather than down, because a slightly bigger wing gets you on foil sooner and the extra power window protects your early progression.

Most riders don't end up with one wing — they end up with three or four spaced about 1–1.5m apart, covering their condition range. The practical approach is to start with the wing sized for your most common wind, then add a second wing for the days you currently skip: bigger for light wind, smaller for strong. You're not collecting gear; you're filling the gaps in your local forecast.

If you're buying for windsurf or kite equipment you already own, check compatibility — but for most people a mid-size wing, a big board and a large foil is the complete beginner package. At outlet prices, a sensible two-wing quiver is one of the better-value upgrades in the sport.
