How to Use the Surfboard Volume & Thickness Guide
Volume (in liters) is one of the most important specs when choosing a surfboard — get it wrong and you'll either struggle to paddle or feel like turns are sluggish. This guide takes your body weight, skill level, and the typical wave height you surf, then recommends a board volume and thickness tendency.
Beginners still getting comfortable with take-offs and paddling do best with volume around 0.65 times their body weight in kg for stability. Intermediate surfers who can already paddle and catch waves comfortably can drop to around 0.45x, and advanced surfers doing turns and maneuvers benefit from dropping further to around 0.32x for sharper control and speed. Higher-volume boards also tend to run thicker.
Wave height matters too. Small, weak waves from knee-to-waist height need a bit more volume to help with paddle power, while big, overhead-plus waves already carry plenty of power on their own, so slightly less volume lets you turn faster and sharper. These results reflect general tendencies, so test-riding a board at your local shop before buying is always a good idea.
Frequently Asked Questions
Higher-volume boards float easily and paddle comfortably, which helps beginners, but that same buoyancy makes turning sluggish and fine control harder. As skill improves, surfers typically move to lower-volume boards for sharper handling and speed.
Bigger waves already supply plenty of power, so you need less paddle assist from the board, and lower volume lets you turn and maneuver more sharply in a fast-moving face. In small, weak surf, extra volume helps compensate for the lack of wave power.
