Wetsuit Size Chart & Fit Guide: How to Find Your Perfect Wetsuit Size

It's May at Bells Beach. The car park at Southside is filling up before the sun's properly over the Otways, and the sets are running clean — 13°C water, a southerly swell lifting the back of every wave into something worth paddling for. The Torquay locals are already pulling on their steamers before the lids come off the flasks. No one's reading a size guide. They already know.

But getting to that point — knowing your suit, trusting it, not thinking about it in the water — starts with getting the right one. We've been building wetsuits for Australian conditions since Brian Singer and Doug Warbrick set up in a Torquay garage in 1969. Not wetsuits adapted from Northern Hemisphere patterns. Suits built for Bells in July, for Margaret River's reefs, for Snapper Rocks in a January cyclone swell, for the cold upwelling at Cactus that catches visitors off guard.
This guide gives you two things: the size charts and the context that makes them useful. Because in Australia, knowing your measurements is only half the job. The other half is knowing your water. Head straight to our size guides page if you already have your measurements. If you're starting from scratch, our beginner's guide to how wetsuits work is a good first stop.

Australian Waters — Know Before You Size

Australia's coastline runs from 10°C Bass Strait swells in a Victorian winter to warm, tropical water off the Queensland coast. Before you open a size chart, you need to know what your local break demands, because thickness changes the fit equation. A 4/3 steamer and a QLD springy are not the same garment in any meaningful sense, and they don't size identically on your body.
Here's a state-by-state breakdown of what Australian water actually looks like, and what you'll need to surf it comfortably.

The Fit Philosophy — What Rip Curl Believes About a Wetsuit

Brian Singer and Doug Warbrick didn't build the first Rip Curl wetsuit because they wanted to sell wetsuits. They built it because they wanted to surf better in cold water. Every design decision since has served the same purpose: build a suit that disappears on your body so the only thing you're thinking about is the wave.

Here's how a wetsuit works. It traps a thin layer of water between the neoprene and your skin. Your body heats that layer, and the suit holds it there. The word that matters is thin. Too much water circulating inside — caused by a loose seal at the neck, wrists, or ankles — and you'll be cold no matter how good the neoprene is.

Too loose: cold water flushes in on every duck dive. Too tight: you're fighting restricted breathing and shoulder fatigue before you've cleared the break. The sweet spot is snug; a second skin that moves with you, not against you.

That engineering goal is what's behind Fusion Dry Seam Technology and E7 neoprene. The Flashbomb Fusion bonds 96% of the suit without a stitch, and the result shows in Bass Strait in July. These features are the reason a well-fitted Rip Curl suit stays warm where other suits don't.

One more thing: wetsuit sizing runs completely differently from clothing sizing. Your boardshorts medium means nothing here. Measure first, then check the chart.

How to Measure for Your Wetsuit

Your measurements are the foundation of everything that follows. Take them seriously. Use a soft fabric tape (not the metal retractable from the garage) and have someone help you if you can. Measure in your underwear for accuracy.

1. Height (cm): Stand straight against a wall, heels together. Measure from the floor to the top of your head. This and chest are the two most important measurements.
2. Weight (kg): Helps narrow options when chest and height point toward different sizes.
   
3. Chest (cm): Wrap the tape around the widest part of your chest, arms relaxed at your sides. Don't flex, don't hold your breath.
4. Waist (cm): Measure at your natural waistline, roughly at belly button level. The tape should feel snug, not tight.
5. Hips (cm, women): Measure around the widest point of your hips, feet together.

Between sizes? Prioritise chest and height over waist and weight. Every time. These determine how the suit seals at the neck, which is the point where water flushing costs you the most warmth.

Write your measurements down before you look at a chart. You'll come back to them.

Rip Curl Wetsuit Size Charts

The charts below are based on Rip Curl's official wetsuit sizing. For the most current measurements and model-specific details, always reference our size guides page before ordering.

Men's Wetsuit Size Chart

Rip Curl men's wetsuits come in standard and tall (T) variants: ST, MT, and LT. If you run long through the torso or legs within a size range, the tall cut gives you extra length so the suit seals correctly at the ankles and wrists. Don't default to the next size up when a tall variant solves the problem.

For model-specific sizing across thickness variants, visit our Men's Wetsuit Guide.

Women's Wetsuit Size Chart

Rip Curl women's wetsuits are engineered for the female form, not adapted from men's patterns. Bust and hip panels align where they need to, and shoulder width is proportionate. Sizing into a men's suit means panels that don't sit right, which translates directly to heat loss and restricted paddling.

For model-specific fit notes and thickness options, see our Women's Wetsuit Guide.

Kids' & Youth Wetsuit Size Chart

For growing groms, sizing up slightly is fine, but the neck seal still needs to close. A gap at the collar loses warmth faster than extra leg length causes problems. Browse Rip Curl's full collection of Kids' and Teens Wetsuits.

Reading the Rails — Is Your Suit a Good Fit?

Reading the rails is how you judge a wave. It's also how you judge a suit. Run through this five-point check in the change room before you commit.

1. Neck seal: Should sit snug with no gap when you lean forward. You can fit two fingers under the collar comfortably. Any more, and water will flush on every duck dive.
2. Shoulder movement: Arms overhead, full rotation. No binding, no pulling across the back. Your paddle stroke depends on this.
3. Wrist and ankle seal: Sleeves should end at or just above the wrist bone. Legs should fall just above the ankle. No excess material pooling.
4. Torso pull: No neoprene bunching at the lower back or behind the knees. The suit should lie flat against your body.
5. The squat test: Squat down fully. If the suit binds across the lower back or pulls tight at the knees to the point of discomfort, size up.
   

If all five pass, you've found your suit.

Between Sizes?

Chest and height over waist and weight. Every time.

The chest and neck seal determine warmth. If your chest measurement puts you at a medium but your waist is pushing toward large, go medium. E7 neoprene has give. A snug waist relaxes after a few sessions. A loose neck seal flushes cold water from the first paddle, and no amount of good neoprene fixes that.

Running long through the torso and legs? Check the ST, MT, and LT tall variants before defaulting to the next size up. They're cut for that body proportion, and the difference in seal at the extremities is real. See the full breakdown at our size guides page.

Still not sure? Come into a Rip Curl store. Our crew knows these suits, and they'll have you sorted before the arvo sesh.

Look After Your Wetty

A suit that's looked after keeps its shape and its fit. A few things that matter:

• Rinse inside and out with fresh water after every session. Salt and sand break down neoprene faster than anything else.
• Store flat or on a wide hanger, never folded on a crease. A sharp fold in neoprene becomes permanent.
• Avoid direct sunlight for storage. UV degrades neoprene faster

Wetsuit Sizing FAQ

What thickness wetsuit do I need for Australian winter?
It depends entirely on your state. Vic and Tas surfers are looking at a 4/3 or 5/4/3 steamer from May through September — Bass Strait in July is not a situation for half-measures. SA surfers typically need a 3/2 or 4/3. WA surfers at exposed south coast breaks like Margaret River should lean toward a 4/3 in winter; the cold bottom-end of 15°C and heavy water movement make a 3/2 a marginal call. NSW crews in Sydney can manage with a 3/2 for most of winter. QLD surfers rarely need more than a springy year-round, though the far south can get cool enough for a light steamer in June and July.

What's the difference between a steamer and a springy?
A steamer is a full-length wetsuit with long arms and long legs. It's what you need for cold water, exposed breaks, and any session where staying warm matters more than unrestricted movement. A springy has short arms or short legs (or both), works well in mild to warm water, and gives you more freedom of movement through the shoulders.

Do I need a different size for a thicker suit?
No — your measurements don't change. But a thicker suit feels more restrictive in the same size, because there's more neoprene to compress. This is why we say snug becomes more important as you move up in thickness. The suit that felt right in a 2/2 springy should feel a bit firmer in a 4/3 steamer. That's normal. Don't size up to get comfortable; the snugness is the point.

My grom grew since last season, should I size up?
Yes, and prioritise height and chest when you do. A little extra room in the body is manageable. A neck seal that doesn't seal, is not. If you're sizing up a full size, make sure the collar still sits snug, even if the legs run a bit long. The warmth loss from a gapping collar will ruin a session faster than extra material anywhere else.

Can I use the same wetsuit year-round in Australia?
Depends entirely on where you surf. Vic surfers almost always need two suits: a summer springy or shorty and a winter steamer. The roughly 8°C swing between Vic's summer and winter water temps isn't something one suit bridges well. QLD surfers may genuinely only need one springy for the whole year. NSW sits somewhere in between; you can get by with a versatile 3/2 steamer for much of the year if you're in Sydney, though some surfers prefer a lighter suit in the summer months.
