If you don't already know your measurements, follow our  wetsuit measuring guide.

Not all brands use the same sizing, so once you've chosen your wetsuit and know the brand, it's important to cross-reference your measurements with the relevant wetsuit size guide, which is available on each wetsuit product page. You can also compare sizes from some of our most popular wetsuit brands.

Not sure how tight your wetsuit should be? When your wetsuit arrives and you try it on, it should fit you like a second skin. You should be able to bend down and touch your toes (or as far as you can normally reach!) and have a full range of motion through your arms and shoulders. However, you also don't want your suit to be baggy anywhere, as it will allow cold water to continuously run through the suit (this is generally referred to as flushing).
