Size Guide

Longer boards paddle faster, catch waves more easily, and offer more stability underfoot — ideal for beginners, noseriding, and small rolling surf. Shorter boards are more responsive and suited to steeper, faster waves with precise footwork.

As a starting point: add 2–3 feet to your height for a longboard, or match your height for a performance shortboard. Every surfer is different — wave type and style matter as much as body size.

Width determines stability and paddle power. A wider board sits higher in the water and is easier to balance on. Narrower boards allow for rail-to-rail transitions and tighter turns.

Most longboards range from 22" to 24" wide. Performance shortboards typically run 18" to 20". For noseriding, a wide, flat nose (16"–18") gives you a stable platform.

Thickness drives volume and float. More float means easier paddling — critical for heavier riders or beginners still building paddle fitness. Less thickness gives you a lower center of gravity and more feel through the water.

A general rule: 2.5" to 3" for longboards, 2.25" to 2.75" for mid-lengths, and 2" to 2.5" for performance shapes. Bum will dial this in based on your weight and target wave conditions.

Rocker is the curve running from nose to tail along the bottom of the board. More rocker makes a board looser and suited to steep, hollow waves. Less rocker gives speed and drive in small, mushy surf.

Our single-fin longboards are shaped with a flat-to-minimal rocker for noseriding speed. Performance single-fins carry a bit more entry rocker for responsiveness without sacrificing glide.
