Kite & Kiteboarding Tools & Calculators
Free, practical tools for kite flyers and kiteboarders — convert wind speed and read the Beaufort scale, size a kiteboarding kite, estimate line pull and kite altitude, and learn the wind window.
Wind Speed Converter
Convert wind speed between knots, mph, km/h, and m/s, map it to the Beaufort scale, and get kite-flying guidance — from too light to fly through the ideal sport-kite window to too strong and dangerous
Kiteboarding Kite Size Calculator
Estimate the right kiteboarding kite size in square metres from your weight and the wind, with a recommended range, a riding-style tweak, and a full weight-by-wind size chart — a starting point, not a rule
Kite Line Tension Calculator
Estimate the pull on your lines from kite area, wind speed, and lift coefficient using F = ½·ρ·v²·A·C_L — in newtons, kgf, and lbf — plus a suggested line strength with a safety factor
Wind Window Calculator
An educational tool: pick an angle within the wind window and see which zone you are in — power, intermediate, edge, or neutral — and the relative pull, with power falling off from the centre to the edge
Kite Altitude Calculator
Estimate how high your single-line kite is flying from the line let out and its angle above the horizon — altitude and ground distance, in metres and feet, with a note on line sag
Beaufort Wind Scale Guide
The full Beaufort scale, force 0 to 12, with wind ranges in knots, mph, and km/h, land and sea descriptions, and a 'what can I fly?' column for kite flyers — filterable and searchable
