Surfboard volume FAQ
What is surfboard volume measured in?
Surfboard volume is measured in liters (L). It tells you how much foam is in the board, and more liters means more float, so the board paddles easier and catches more waves.
How do you calculate a surfboard's volume?
A surfboard's volume comes from its length, width, and thickness, adjusted for how full the board's shape is. A soft-top holds more foam than a thin hard board of the same size, so shape matters too. Enter your board's dimensions above and the calculator estimates the volume in liters.
Where do I find my surfboard's volume?
Many surfboards have the volume stamped on the deck near the tail or the stringer. If yours doesn't, enter its length, width, and thickness above and the calculator will estimate the volume for you.
How accurate is estimating volume from dimensions?
Estimating volume from dimensions lands within a liter or two of a board's real volume. The exact figure also depends on the board's rocker and rail shape, so if the volume is printed on your board, use that number instead.
How much volume do I need?
The volume you need depends on your weight and your ability, not just the board itself. Use the surfboard size calculator to find the volume you should be riding.
