Work out your ideal volume from your weight and your level in a couple of seconds

What to buy once you know the volume

Volume narrows the board down. These are the three things that decide whether the session is actually any good.

  • A board at this volumeLitres are the spec that matters, not length. Two boards of the same length can be 15 L apart, and the thinner one is the reason a beginner never catches anything.
  • A wetsuit for your water temperatureCold is what ends sessions early and stops people going back. Work out the thickness before you shop — it changes the price bracket entirely.
  • A session on a demo board first, if you can get oneStanding on the volume beats reading it. A number gets you to the right shelf; ten minutes of paddling tells you whether the board floats you the way you expected.

Reference table: volume by level

LevelMultiplierExample at 75 kgBoard type
Beginner× 1.075 LLongboard / soft-top
Intermediate× 0.645 LFunboard / fish
Advanced× 0.4534 LShortboard
Expert× 0.3526 LPerformance shortboard

These figures are a starting point. In hollow, powerful waves, drop 5–10 L. In soft waves, add 5–10 L.

Why does volume matter so much?

A surfboard's volume (measured in litres) determines its buoyancy. The higher the volume, the more the board floats, the easier it paddles, and the more forgiving it is of mistakes, which is exactly what a beginner needs. A lower volume, on the other hand, offers more responsiveness in hollow waves, but demands more experience.

The basic rule

As a beginner, aim for at least the equivalent of your bodyweight in litres (75 kg → 75 L minimum). Intermediates sit around 60% of their bodyweight, advanced surfers around 45%.

Conditions and volume

In soft summer waves, bump up the volume to paddle faster into slow-moving swell. In hollow, powerful waves (autumn at Thurso or Watergate Bay), a lower volume gives you more control in the barrel.
