Wetsuit Size Guide — Rip Curl and O'Neill Size Charts
Getting the right wetsuit size is as important as choosing the right model. A wetsuit that's too loose flushes cold water constantly. One that's too tight restricts paddling and breathing. This page covers size charts for both brands we carry — Rip Curl and O'Neill — for men, women, and kids.

How to measure yourself
Height — stand straight against a wall, heels together, and measure from floor to the top of your head.
Weight — use your current weight, not your goal weight.
Chest — wrap a soft tape measure around the widest part of your chest, arms relaxed at your sides. Don't flex, don't hold your breath.
Waist — measure at your natural waistline, roughly at belly button level.
Key tip: If your measurements fall between two sizes, always prioritise the better fit for chest and height. These determine how the suit seals at the neck and wrists — the two main points where water flushing costs you warmth. Wetsuit sizing has nothing to do with clothing sizing. A medium in boardshorts does not mean a medium in a wetsuit.
Tall sizes: Rip Curl offers ST, MT, and LT (short-tall, medium-tall, large-tall) for surfers who run long through the torso or legs. If the suit feels short at the ankles or wrists within your normal size, try the tall version. O'Neill offers ST and MT options as well.

Kids' wetsuit sizing — Rip Curl and O'Neill
Kids' wetsuits are sized by height and weight rather than age, since body proportions vary so much. The most reliable method is to measure your child's height and weight and match to the size chart. Both Rip Curl and O'Neill run youth sizes from approximately 8 to 16 years, with toddler/small kid sizing available in select models.
| Size | Height | Weight | Age (guide only) |
|---|---|---|---|
| 8 | 48"–50" | 50–60 lbs | 7–8 years |
| 10 | 52"–54" | 63–75 lbs | 9–10 years |
| 12 | 56"–58" | 78–92 lbs | 11–12 years |
| 14 | 60"–62" | 95–110 lbs | 13–14 years |
| 16 | 63"–65" | 112–128 lbs | 15–16 years |
Use age only as a rough guide — always size by height and weight. Kids who run tall for their age should size up.
Tips on fit
A wetsuit should feel snug, not painful. Test by taking a deep breath and raising both arms overhead — if you can do both without restriction, the fit is correct. Neoprene stretches slightly after a few sessions and conforms to your body shape, so snug now means a good fit long-term. A suit that feels slightly loose new will only get looser.
If your measurements fall between sizes, size down if chest is the primary measurement, size up if height is the primary mismatch. When in doubt, come into the store — we fit wetsuits every day and can help you get it right the first time.
