How to choose the volume of a surfboard?

The choice of volume for a surfboard is directly linked to the weight and level of the rider.

The greater the volume, the more the surf will float, and the easier it will be to paddle... less effort when taking off, but more effort when maneuvering, as you'll have to press down harder to engage the turns. The surfboard will be tolerant and adapted to small waves and average conditions. 

On the contrary, a surfboard with a more contained volume will have more grip in the water, will be more reactive in maneuvers but will require more effort in the take-off. Once you've started out with a small-volume surf, there's no time to get bored: you'll have to keep up your maneuvers and optimize your placement in the wave to compensate for the lower buoyancy.

How do you calculate the ideal volume of a surfboard?

There are tables to estimate this volume, taking into account your weight and level:

Today, it's possible to gauge your ideal board volume using a mobile application called Boardline. I invite you to read this excellent Surf Session article on the subject.

Here's a summary of the volumes in the PRISM SURFBOARDS range. Do you find what you're looking for?
