Free surfboard volume calculator
Stop guessing your board volume.
Setwave runs a documented, rule-based calculation — the same Guild Factor methodology shapers use — and shows you exactly why it landed on your range. From there you can match curated boards to that range with the same kind of rules, not a black box.
Find the right board
Quick answers
- What volume surfboard should I ride?
- Starting volume is your weight in kilograms times a Guild Factor. At 160 lb (72.6 kg), surfers in the absolute beginner band start at 58–72.5 liters, before wave, frequency, age, and board adjustments.
- How much volume does a beginner need?
- Absolute beginner surfers use Guild Factor 0.8–1, which is 58–72.5 liters at 160 lb (72.6 kg). Improver surfers use Guild Factor 0.5–0.65, which is 36.5–47 liters at the same weight.
How it works
Answer a few questions
Weight, ability, how you surf, and the waves you ride most. Under two minutes — no account needed.
Get an explained range
A recommended volume range in liters, with every adjustment shown and why it was applied. Never a single number pretending to be exact.
See boards that actually fit
From your results, match a curated set of boards scored against your profile with a rule-based engine — not a black box.
A range, never a guarantee
Every result comes from a documented formula, versioned so we can improve it openly over time — not an AI deciding your board size on the fly. We show our full methodology and every source it's built from directly on the calculator page. Board matches use that range plus the filters you add; they are scored by rules, not guessed.
