Wing size calculator: rig right, fly early.
Weight, wind, level — and out comes the wing that gets you on foil instead of taxiing in circles. The rule of thumb brand charts are built around, running live.

How wing sizing actually works
Winging has a split personality: you need real power to taxi and pop onto foil, then almost none once the mast is flying. That's why level matters as much as weight. Learners live in the power-hungry phase, so the calculator adds ~15%; advanced riders pump onto foil early and shave 10% off. The core rule — 1.05 × weight (kg) ÷ wind (knots) — assumes you're somewhere in between.
Two things the formula can't see: your board and your foil. A board at weight-plus-30-litres floats you through the clumsy phase and flatters a smaller wing; a sinker demands more canopy while you're underwater building speed. Likewise a big low-aspect front wing lifts at lower speed and forgives an undersized hand wing. When your setup changes, re-run the number. Threshold-by-threshold guidance lives in how much wind you need to wing foil, and the wing foiling alarm page covers the 12–22 kt sweet spot most wingers chase.
