How do I find the right size wetsuit?

December 21, 2022
Finding the right size wetsuit can be quite a challenge. It should fit like a second skin, tightly wrapped around your body. After all, a wetsuit only works when the fit is right. On the other hand, you don't want it to be too restrictive or tight, and want to avoid excess material in areas like your armpits, lower back and behind your knees. But don’t worry, we offer suits for every body type and gladly help you choose your correct wetsuit size. This makes wetsuit shopping a lot easier than before. Keep your measurements at hand, have a look at our wetsuit sizes guide and order the right size without having to try it on in a sandy fitting room!
How do I find the right size wetsuit?

How to size a wetsuit?

How should a wetsuit fit? As described above, it should fit tightly around the body. Only then, a thin layer of water can be trapped between the neoprene and your skin to keep your body warm. When the suit is too large and the material piles up in certain areas, cold water seeps in and runs through the suit (a phenomenon known as flushing). A wetsuit that is too small, however, is too tight and can restrict your freedom of movement in the water. This especially the case with winter wetsuits: the thicker the neoprene, the less flexible it is. When you try on your suit, you must be able to bend down and touch your toes, and move your arms and shoulders freely.

Tip: Remember that in addition to wetsuit sizes, wetsuit thicknesses are also very important! Check out our page about "what thickness wetsuit do i need at what water temperature?"


O’Neill wetsuit sizes explained

Rather than on height, O’Neill wetsuit sizes are based on body types. While some are tall and slim, others have broad shoulders and a big chest, and yet another one is a bit heavier. Therefore, we do not only offer small, medium, large and extra large wetsuits, but multiple variants of each. SS (small small) for example, is a great fit for shorter persons with a relatively big waist and chest, while ST (small tall) is suited for taller persons that have the same waist and chest circumference. The normal S is the best choice for people who fall in between.

Wetsuit sizing tips: how to measure

Height: stand right up and measure the length from the ground to the top of your head.

Weight: measure your weight on a time of day you would normally go surfing. In the morning, you are usually lighter so don’t cheat.

Chest: keep your arms relaxed by your side and measure the widest part of your chest.

Waist: breathe out and measure around your natural waistline.
