Wing size chart by weight and wind

Wing size by rider weight, wind speed, foil setup, and progression level.

The Quiver / Guides / Wing Size Guide

Wing size is the difference between slogging on your knees and lifting cleanly onto foil. This guide gives a practical starting point for inflatable wing sizes by rider weight and wind, then shows how board volume, front foil area, and skill level move the final choice.

Wing Size Guide chart

The table is tuned for normal freeride wing foiling with a mid-size front foil. Riders using large beginner foils can often go a half meter smaller once they are efficient, while small high-speed foils usually need more wing to take off.

Match the wing to the foil

A large, high-lift front foil reduces takeoff speed, so the wing does not need to drag you through the water as aggressively. A smaller high-aspect foil needs more board speed before it flies, which often means a larger wing or stronger wind. Beginners should size the whole system together: stable board, forgiving foil, and a wing that gives steady pull rather than twitchy power.

Beginner sizing

Most learners progress fastest in moderate wind on a wing that is large enough to water-start without frantic pumping, but not so large that the tips catch or the handles become hard to control. A 75 kg beginner commonly starts around 5 to 6 m in 14-20 knots, with lessons and local spot advice deciding the final size.

Two-wing quiver

A useful first quiver for a 65-80 kg rider is often a 5 m main wing and a 4 m strong-wind wing, then a 6 m or 6.5 m light-wind wing later. Heavier riders shift that quiver up. Lighter riders shift it down. Buy the main wing for your most common clean wind, not the rare extreme days.

Common wing sizing mistakes

The biggest wing-sizing mistake is going too small in hopes of "growing into it." An undersized wing makes water starts impossible — you cannot generate the power to get the board out of the water. Many wing foilers who quit in their first month were on a wing 0.5 to 1 m too small for their weight and local wind.

The second mistake is owning only one wing and skipping sessions outside its window. Wing foiling has a wide wind range across a single season. Most riders need at least two wings (a light-wind 5.5 to 6 m and a strong-wind 4 to 4.5 m) to cover most of their typical conditions.

The third mistake is sizing for the forecast average instead of the gusts. A 15 kt forecast often means 12 to 18 kt with 22 kt gusts. Size your wing for the average, not the peak. An overpowered wing in a gust is dangerous, especially on the water start.

Wing buying checklist

How to use this wing guide

Find your weight band in the chart, then pick the wing for your typical wind. A 75 kg rider in 18 kt gets a 5 m as a sweet spot. Beginners should size up half a meter. Extra power makes water starts easier and reduces the time spent dragging through chop.

Your foil setup changes effective wing size. A high-aspect, high-area front foil generates more lift at the same speed, so you can ride a smaller wing than the chart suggests. A small, low-aspect surf foil needs more wing power to maintain takeoff speed.

Run the calculator twice when in doubt. Once for your typical wind, once for the gust forecast. If the recommendations are more than 1 m apart, you probably need a two-wing quiver for that day rather than one compromise size.

Tuning for your local wind

Coastal spots with gusty, thermal-driven wind reward smaller wings. Sizing down half a meter gives you more handling margin in the peaks. Steady lake or open-ocean wind lets you ride larger because gust spikes are predictable and rare.

Side-offshore wind is the highest-risk direction for wing foiling because depowering means drifting out to sea. Size down on offshore days so you can stay in control through gusts, and never go bigger than your reliable self-rescue size. Onshore wind forgives over-sizing; offshore wind does not.

Frequently asked questions

What size wing should a 75 kg rider use?

A 75 kg freeride rider commonly uses a 5 m wing in 15-18 knots, a 4.5 m around 19-23 knots, and a 6 m or larger wing in lighter wind.

Is a bigger wing better for learning?

A slightly larger wing helps in steady moderate wind, but an oversized wing is harder to handle and can overpower beginners in gusts.
