The Secret to Better Surfing: Volume
In the world of modern surfing, Volume (measured in Liters) is the most important metric for choosing a board. It determines how well you can paddle, how easily you can catch waves, and how the board responds under your feet.
What is the Guild Factor?
The Guild Factor (GF) is a mathematical ratio used by pro shapers to calculate volume. It is simply your weight in kilograms multiplied by a skill-based constant.
- High GF (0.50+): More float, easier paddling. Best for beginners or weak waves.
- Low GF (0.34 - 0.36): Less float, more maneuverability. Best for pros or powerful waves.
Why Volume Matters
If you have too little volume, you will struggle to catch waves and the board will feel "sinky" during turns. If you have too much volume, the board will feel "corky" and difficult to duck-dive or put on rail. Our Advanced Surfboard Volume Calculator helps you find that "sweet spot."
Factoring in Construction and Fitness
- Epoxy vs PU: Epoxy (EPS) boards are naturally more buoyant than traditional Polyurethane (PU) boards. Most surfers subtract 1-3 liters from their PU volume when choosing an Epoxy board.
- Fitness: If you only surf once a month, you need more volume to help your paddling. If you are extremely fit and surf daily, you can get away with a lower volume for higher performance.
