A wetsuit that fits well is a real asset when you're enjoying watersports - whether that's scuba diving or para-gliding. Sainsbury's has prepared this handy size guide to help you get the perfect size.

The wetsuit shouldn't be so tight that you have trouble breathing or your movements are overly restricted. You also don't want it to be too loose. This would let water flow freely through the suit, and you'd lose all the benefits of trapped water being warmed by your body.

For a correct wetsuit fit, your wrists and ankles should be snug. This is an area where water can easily seep in, so these should not have gaps. The neck should also be snug but remember, you need to breathe. Not too tight. There shouldn't be any large gaps in the underarm or crotch area. You will, however, probably have a gap at the small of the back. This is normal.
