Find Your Volume.
Board volume (measured in liters) is the single biggest factor in how easily a board paddles and catches waves. Answer three quick questions for a starting point.

How it works
Surfers often estimate volume as body weight (kg) × a “skill factor.” Beginners need more float (around 1 liter per kg or more); advanced surfers ride far less. Fitness nudges it up or down.
More is better, early on
Too little volume is the number one thing that slows beginners down. A bigger board catches more waves, and more waves means faster progress.
Talk to a local shop
This is a starting point, not a rule. Your local surf shop knows your waves and can help you find the right board, new or used. Read our first-board guide.
