Board Type Guide

🏄

Longboard

65–120L+

9'0"+ length. Maximum stability and paddle power. Ideal for beginners and nose-riding. Great in small, mellow waves.

🌊

Funboard / Malibu

50–75L

7'0"–8'6". The middle ground. Easier to paddle than a shortboard, more versatile than a longboard. Great for progression.

🐟

Fish / Hybrid

35–55L

Wide, thick and short. Excellent in small to medium mushy waves. Fast and fun with good paddle power for its length.

⚡

Shortboard

24–38L

High-performance shape for experienced surfers. Responsive and manoeuvrable in good waves. Requires strong paddling fitness.

🎯

Gun

30–50L

Long, narrow and pointed. Designed for big, powerful, fast waves. Provides speed and control when it matters most.

🏖️

Mid-length

40–65L

7'0"–8'6". Relaxed, flowing style. Great for intermediate surfers or experienced surfers wanting a versatile daily driver.

How Surfboard Volume is Calculated

Volume in litres (L) is the most reliable way to size a surfboard for your body weight and ability. The industry-standard multipliers are: Beginner: 0.6–0.7× body weight in kg, Intermediate: 0.35–0.5×, Advanced: 0.25–0.35×, and Pro: 0.20–0.28×.

Wave type and fitness adjust the result — mushy small waves reward extra volume for paddle power, while hollow powerful waves reward lower volume for performance. Fitness level affects how easily you can paddle and catch waves on lower volume.

These are starting points. Personal preference, surf style, and conditions all play a role. Many surfers ride a range of boards for different conditions.
