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.
  1. Weight - Be brave, strip off and 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.
