Billabong Size Guide

Billabong is a legendary action sports brand renowned for its innovative wetsuits, swimwear, and lifestyle apparel. Since 1973, the brand has been crafting products for surfers, swimmers, and action sports enthusiasts who demand both performance and style. Billabong's sizing reflects the brand's commitment to freedom of movement and comfort in and out of the water.

The brand is known for offering an extensive range of sizes across multiple product categories, from children's ranges through to generous plus-size offerings for adults. Whether you're shopping for wetsuits designed with precision water sports engineering, swimwear that combines style with functionality, or casual outerwear, Billabong caters to diverse body types and preferences.

Important note: Women's swimwear at Billabong runs slightly smaller than other categories. If you're between sizes, consider sizing up for a more comfortable fit. The brand's sizing is consistent across most product lines, though wetsuits have their own specialised charts accounting for height and weight proportions.

How to Measure

Accurate measurements are essential for finding your perfect Billabong size. Follow these steps carefully, and use a soft measuring tape pulled snug — but not tight — against your body:

1. Chest: Wrap the tape measure horizontally around your chest at the fullest point, directly beneath your armpits. Keep the tape parallel to the ground and ensure it's not too tight.
2. Bust (Women's): Measure underneath your arms around the fullest part of your bust. This is typically 2–3 inches below your shoulder bone.
3. Waist: Find your natural waistline (the smallest part of your torso, typically just above your hip bones). Measure horizontally around this point. The tape should feel comfortable without constricting your breathing.
4. Hips: Measure around the fullest part of your hips and buttocks, approximately 7–9 inches below your waist. Stand with your feet together and keep the tape level.
5. Inseam (Trousers & Snowwear): Wear shoes you'll typically wear with the item. Measure from your inner thigh down to your ankle, or have someone measure from your crotch to the top of your shoe.
6. Height (Wetsuits & Snowwear): Stand barefoot against a wall with a book on your head. Mark the wall at the top of the book and measure from the floor to this mark.
7. Shoe Size: Measure your foot from heel to toe while standing. Use this measurement to cross-reference the shoe size chart below.
