Find your perfect setup based on your weight, skill level, and wind conditions.
How It Works
Getting the right wing foiling gear makes all the difference between frustration and flow. This calculator takes the guesswork out of equipment selection by recommending the optimal board volume, wing size, and foil area for your specific conditions.

Find your perfect setup
Simply enter your weight, select your experience level, and adjust the wind conditions slider to get instant recommendations for:
- Board Volume – The right flotation for your weight and skill level
- Wing Size – Matched to current wind strength for optimal power
- Foil Size – Tailored to get you flying efficiently
Understanding Your Results
Board Volume (Litres) Your board volume determines how stable and floatable your setup feels. Beginners need more volume for easier water starts and stability, while advanced riders can handle lower volumes for better maneuverability. The calculator factors in your weight and experience to find your sweet spot.
Wing Size (m²) Wing size directly correlates with wind strength. Lighter winds require larger wings to generate enough power, while stronger winds need smaller wings to stay in control. As you progress, you’ll develop a quiver of wings to cover different conditions.
Foil Size (cm²) Foil area affects how early you get up on foil and how much speed you need to maintain flight. Larger foils generate more lift at lower speeds (great for learning and light winds), while smaller foils offer better top-end speed and maneuverability for experienced riders in stronger conditions.
Tips for Using This Calculator
- Be honest about your experience level – It’s better to have slightly more board volume than struggle to get on foil
- Wind conditions matter – Strong winds (22+ knots) change everything; you’ll want smaller gear across the board
- These are starting recommendations – Personal preference, local conditions, and your progression will all influence your ideal setup
- Consider building a quiver – Most riders end up with 2-3 wing sizes and potentially multiple foils as they progress

Frequently asked questions
What size wing foil board do I need for my weight?
Start from your body weight in kilograms and add a buffer for skill level. Beginners add about 40 litres, intermediates about 10, and advanced riders take about 10 off. An 80kg beginner lands near 120L, the same rider at intermediate near 90L. The calculator rounds to the nearest 5 litres and never goes below 30L.
How do I calculate wing foil board volume?
One litre of board volume floats roughly one kilogram, so your body weight in kilos is the baseline in litres. That baseline alone floats you but gives nothing spare for a clumsy water start, which is why the skill buffer matters: plenty of extra volume while you are learning, progressively less as your technique improves.
What size wing do I need for wing foiling?
A rider around 75kg starts at roughly 5.0m². Add about 1m² in light wind and take about 1m² off in strong wind, then add another 0.5m² while you are still learning, since a beginner needs more power to get going. The calculator keeps results between 2.5 and 8.0m² and rounds to the nearest half metre.
What size foil do I need for wing foiling?
Front wing area tracks skill more than anything else: around 2000cm² for beginners, 1500cm² for intermediates and 1000cm² for advanced riders. From there it shifts by roughly 10cm² for every kilo you are above or below 75kg, goes up in light wind and down in strong wind. Bigger foils lift earlier, smaller foils carry more speed.
Is the wing foil calculator free?
Yes. It runs in your browser, needs no sign-up or email address, and updates instantly as you change your weight, skill level or wind conditions. Treat the numbers as a starting point for demoing gear rather than a final answer, since board shape and wing design vary between brands.
