Make paddling easier.
Volume describes the space a board occupies. More volume generally adds flotation, but length and shape also affect how a board paddles.

YOUR SUGGESTED RANGE

How to use your result
An estimate, not a guarantee. Length, width, rocker, and volume distribution matter too. Compare with a board you already enjoy.
02 / LOOK BEYOND THE NUMBER
Liters are just the beginning.
Match your local waves.
Small, soft waves often suit a fuller shape and extra float. Steeper waves call for a shape you can control, rather than simply fewer liters.
Choose room to progress.
New surfers benefit from stable, forgiving boards. A wide learner soft-top is usually a more useful starting point than a compact performance board.

Read the guide ↗A few common questions.
Can I calculate a board’s actual volume from its dimensions?
Length × width × thickness measures a rectangular box, not a shaped surfboard. Rails, nose, tail, and rocker change the result. Use the manufacturer’s listed volume when available.
Should fitness change my choice?
If paddling endurance is limited, consider the upper end of the range and a forgiving outline. A fitter surfer may manage less float, but fitness cannot replace technique.
Does a longboard need the same volume as a shortboard?
No. Longboards carry more volume by design. This tool uses separate, broad ranges for midlengths and longboards; use the maker’s rider-weight guidance and talk to a local shaper or surf shop before buying.
03 / TRANSPARENT BY DESIGN
How we estimate your range.
This first-version tool multiplies your weight in kilograms by a broad liters-per-kilogram range. Our editorial starting factors are 0.80–1.00 for beginners, 0.55–0.70 for progressing surfers, 0.40–0.50 for intermediates, and 0.32–0.40 for advanced surfers.
Fish and small-wave boards add 10%. For experienced surfers, midlengths use at least 0.60–0.80 and longboards at least 0.85–1.10. Beginner ranges are kept generous for every style. These are our provisional heuristics, not a manufacturer formula or a validated fitting system.
