What size am I in a wetsuit?Updated 14 days ago

Choosing the right wetsuit size is essential for getting the best possible comfort, flexibility and performance in the water. Unlike everyday clothing, a wetsuit needs to fit snugly against your body to work effectively. However, finding the right fit can sometimes be confusing, particularly if your measurements fall between two sizes or you’re new to wearing a wetsuit.

At ZONE3, we offer a range of wetsuits designed for different swimming needs and performance levels. While your body measurements provide a useful starting point, the fit of the individual wetsuit and your personal preferences should also be considered.



The best place to start is by checking the size guide on the product page for the wetsuit you’re interested in. Our sizing can vary between models, so it’s important not to assume that the same size will fit you across our entire range.

Our size guides consider several measurements to help you find the best fit. If your measurements fall across different size categories, we recommend using the following order of importance when deciding which size to choose: weight first, followed by chest measurement and then height. When measuring your chest, take the measurement on a full inhale. This will help you identify the most suitable size when your measurements don't all align with a single size category.

If you find that your measurements suggest two possible sizes, don't worry. Many swimmers can achieve an acceptable fit in more than one size, and the best choice will depend on the wetsuit model, your body shape and the type of fit you prefer.


It's important to remember that a wetsuit should feel snug when you first put it on, as this helps it work effectively in the water. It may feel tighter than you’re used to with everyday clothing, but it should not restrict your breathing or significantly limit your movement. Getting the right fit is just as important as choosing the right size, so for more advice on how your wetsuit should feel and what to look for when trying it on, take a look at our How Do I Fit My Wetsuit? article.
