How to Choose Surfboard Volume
Surfboard volume (measured in liters) determines how much float a board has. Getting the volume right for your weight and skill level is one of the most important decisions in surfing equipment. Too little volume and you'll struggle to paddle and catch waves; too much and the board feels sluggish and hard to maneuver.
A common guideline: beginners need 100–120% of their body weight in liters. A 150 lb (68 kg) beginner needs 68–82 L. Intermediates use 70–90% (about 48–61 L at 150 lb). Advanced surfers prefer 40–65%, prioritizing maneuverability over buoyancy.
Wave size also matters. Mushy, small waves reward high volume — you need the extra float to generate speed. Steep, powerful waves suit lower-volume boards that pivot quickly and fit into the pocket more precisely.
Frequently Asked Questions
A fish is a wide, twin-fin board with extra width that excels in small, weak waves. A funboard (or mid-length) is 7–8 ft with moderate volume — a great step-down from a longboard. A shortboard is typically under 6'6", thin, narrow, and high-performance, built for powerful surf and aggressive surfing.
A used foam (soft-top) board or a used longboard is ideal for beginners. Beginners ding boards frequently during learning, so starting with an inexpensive board protects your budget. Once you're consistently catching waves and standing, invest in a better board that matches your progression.
Yes. A fit, athletic surfer with strong paddling and good balance can often handle less volume than someone of the same weight who is less active. If you're fit and athletic, you may be comfortable at the lower end of the recommended volume range or even slightly below it.
