What Size Surfboard Do I Need?

Wondering what size surfboard you need? You're not alone. Many people have the same question when they first start surfing.

We’ve put together this handy guide with a Surfboard Volume Calculator to help you decide. That way, you’ll know how to choose the right surfboard for you.

Our Surfboard Volume Calculator

Volume is one of the most important factors to consider when choosing a surfboard. Your body weight, fitness, skill level as well as the type of waves you want to ride will ultimately determine how much, or how little volume you need.

Surfboard volume is a measure of how much water your board displaces and is usually expressed in liters. The bigger the volume, the bigger the waves the board can catch.

  • Higher volume boards paddle easier, are more buoyant and stable, and therefore are better for beginners and older surfers.
  • Lower volume boards turn faster and with less effort, however they’re not as stable and require more effort to catch waves. For these reasons they’re better for more experienced surfers.

As a general rule, a beginner should be riding the equivalent of 100% of their body weight in volume. i.e. A beginner weighing 176 lbs / 80kg should be riding a surfboard around 80 litres in volume. Alternatively, an experienced surfer can ride a board that’s around 40% of their body weight. A pro might ride 30% of their body weight. This formula varies depending on wave conditions, age and how often you surf.

To find out what size surfboard you need, select your skill level and enter your weight. NB: These volumes should be used as a guide only.

The Volume of a Surfboard

There are a few different measurements that go into understanding the volume of a surfboard.

  • Length: The first and most important measurement is the length of the surfboard. This determines how much water the board can displace.
  • Width: How wide the board is will determine how stable it is.
  • Thickness: The thickness of the board will determine how buoyant it is.

Determining the Volume of a Surfboard

To calculate the volume of your surfboard, simply measure the length, width, and thickness of your board and multiply those numbers together.

For example, a 6'0" x 20.5" x 2.5" board would have a volume of 36 liters. Once you know the volume, you can use that number to help you choose the right size for the waves you'll be riding.

As a general rule of thumb, a board with a higher volume will be more stable and easier to paddle, while a surfboard with a lower volume will be more steerable. Check out our super handy Surfboard Volume Calculator by entering your skill level, weight, and budget.
