For a wetsuit, we find that your weight is usually the most important measurement to follow. Height is less critical as a wetsuit will still function well if the legs are a little too long or short. We also suggest going for the smaller size if you are tossing up between two sizes.. most women's returns come back because the wetsuit fitted 'Too large'.
  1. Weight - Jump on the scales to weigh yourself.
  2. Height - Your full body height, measured from the floor to the top if your head.
  3. Bust - Keeping the tape level, measure under your arms around the fullest part of the bust.
  4. Waist - Measure at the narrowest part of the natural waistline with no tension around the tape.
