Kids grow fast, but resist buying a wetsuit to “grow into.” An oversized suit flushes cold water and will put a child off surfing. Buy to fit now, or rent until they stop growing.
The chart gave you a number. Here’s what it can’t tell you.
A chart is good at exactly one thing: the number. It won’t tell you that most surf schools hand you the board, the wetsuit and the leash with the lesson — so the gear you just looked up may not be the first thing you need to buy at all. The free Beginner’s Surf Guide covers the rest:
- What your school already provides, and the short list worth packing yourself
- The five questions to ask before you book — and the red flags hiding in the answers
- How lesson one actually runs, from dry-sand pop-ups to your first green wave
- The lineup rules nobody explains until you’ve broken one

How a wetsuit should fit
- TorsoFlat against your chest and back with no air gaps. The lower back is the #1 place loose suits flush cold water.
- Shoulders & armsSnug but able to rotate freely. If you can’t paddle comfortably on land, it’s too small.
- CrotchPulled all the way up. Any sagging here means the whole suit is too big.
- Wrists & anklesClose-fitting seals to limit water entry. Cuffs should sit at the joint, not past it.
- NeckClose but not choking. Too tight chafes; too loose lets water pour in.
Quick test: once zipped, reach both arms overhead and take a deep breath. If you can do both without strain and there are no loose folds, the fit is right.
A note on brand sizing
Wetsuit sizing is not standardized. A medium in one brand can fit like a large in another, and cuts vary between a brand's budget and premium lines. Use the chart above to find your starting size, then always cross-check the manufacturer's own chart — they list the exact height, weight, and chest ranges for each suit. If you're buying online, read recent reviews for “runs small/large” notes.

Frequently asked questions
How should a wetsuit fit?
A wetsuit should fit like a second skin — snug everywhere with no loose folds, gaps, or air pockets, especially in the lower back. It will feel tight on land; neoprene loosens slightly once wet. You should still be able to raise both arms fully overhead and breathe normally. Any sagging in the crotch or pooling at the lower back means it’s too big and will flush cold water.
What size wetsuit am I if I’m between sizes?
Weight is the single most important measurement, so size to your weight first and then sanity-check against your height. If you fall between two sizes, look for a tall (T) or short (S) variant of your weight size before jumping a full size. When truly stuck, size down — a slightly snug suit keeps you far warmer than a loose one.
Are wetsuit sizes the same across brands?
No. O’Neill, Rip Curl, Billabong, Xcel, and Patagonia each cut slightly differently, and every brand publishes its own chart. This chart is a reliable starting point, but always check the specific brand’s size chart before buying — especially online.
What do MT, MS, and LT mean?
They are height variants of a standard size. M is medium, MT is medium-tall (same chest as M but a longer torso and limbs), and MS is medium-short. These variants let taller or shorter surfers match their weight size to their build for a proper fit.
Should I size up for a thicker winter wetsuit?
No — use the same size. A 5/4mm winter suit should fit just as snugly as a 3/2mm summer suit. Thicker neoprene is warmer because it seals out water, and a loose winter suit defeats the purpose by letting cold water flush through.
Try a wetsuit before you buy
Not sure of your size? Many surf shops rent wetsuits so you can test the fit and thickness before committing to a purchase.
