BESTDIVE Wetsuit Size Guide

Wetsuit sizing varies greatly by body type and fit. Use the charts below to find your ideal size.

How to Measure

Chest

Measure horizontally around the highest/fullest part of your chest.

Waist

Measure horizontally 2 cm above your navel.

Hip

Measure horizontally around the highest/widest part of your hips.

How to Select Your Size

Match circumference measurements to your actual body size. If the circumference runs small, wearing a thicker inner layer is recommended.
Top and bottom do not need to be the same size.
Suits are designed as unified top-bottom sizes — always base your selection on circumference first.
If unsure between two sizes, wearing a thinner or no inner layer is the better approach for a slightly smaller size. Avoid choosing a size that is too small.
All measurements are in cm and kg.

Size Selection Priority

Height: If your height is at the upper limit of a size range, go up one size. (e.g., for 170–177 cm, if you are 177 cm, choose the next size up.)
Circumference over weight: When both circumference and weight apply, always prioritize circumference.
If circumference fits but weight exceeds the upper limit, go up one size.
