Wetsuit size guide

Size charts can be tricky. An M from ION won't necessarily fit like an M from Mystic or Sooruz. Plus, not all brands offer short (S) or tall (T) sizes.

We've gathered the official size charts for the nine wetsuit and neoprene accessory brands we carry: ION, Manera, O'Neill, Prolimit, Mystic, Ride Engine, Billabong, Rip Curl, and Sooruz. Each chart was re-checked on September 25, 2026, directly on the brand's website. Any discrepancies found since the previous version have been corrected.

Measure Yourself Before Checking the Chart

Measure yourself in your underwear, barefoot, using a tailor's tape measure. For most charts, four values are enough:

• Body Size: Stand with your back against a wall, heels together. Measure from the soles of your feet to the top of your head.
• Weight: Weigh yourself in the morning on a reliable scale.
• Chest Measurement: Measure under your armpits at the widest part, keeping the tape measure horizontal.
• Waist Measurement: Measure at your navel level, without holding your breath.

For ION boots, the brand provides the insole length, with a tolerance of plus or minus 5 mm. Place your heel against a wall and measure to the tip of your longest toe. For ION gloves, measure your hand circumference at the knuckles.

Men's Wetsuits

ION men's sizes

The EU code appears on the label and in the ION product code: 94 for an S Tall, 25 for an M Small. This code helps avoid confusing two sizes that share the same letter.

Manera men's sizes

Manera doesn't publish chest or waist measurements. Their body size ranges are broad, so your weight is the deciding factor.

O'Neill men's sizes

Prolimit men's sizes

Mystic men's sizes

Mystic doesn't provide weight, and their current chart no longer includes ST. If you're tall and slender, the MT will only fit if your chest measurement reaches 94 cm.

Ride Engine Men's Sizes (RE_X Range)

Ride Engine publishes its chart in feet, inches, and pounds only. The values above are our conversion to the nearest centimeter and kilogram. If you're in doubt about a size limit, please call us.

Billabong men's sizes

Rip Curl men's sizes

Rip Curl's European size chart doesn't provide weight. Leg and torso lengths primarily help you choose between a regular and a tall size.

Sooruz men's sizes

Women's Wetsuits

ION women's sizes

Manera Women's Sizes

O'Neill women's sizes

Prolimit women's sizes

For XS, the Prolimit chart indicates a chest circumference of 60 to 81 cm, which appears to be a typo. We've kept the only reliable reference: a maximum of 81 cm.

Mystic women's sizes

Ride Engine Women's Sizes (RE_X Range)

GlissEvolution's conversion from the Ride Engine chart in inches and pounds, rounded to the nearest centimeter and kilogram.

Billabong women's sizes

The Billabong France guide lists a waist circumference of 71-76 cm for XXS, which is more than for XL. This is a data entry error. We display the value from the American Billabong guide, 58-63 cm, which is consistent with the inch column in the French guide.

Rip Curl women's sizes

Sooruz women's sizes

Kids' Wetsuits

For children, body size matters more than age. A fast-growing child can go up a size for the season, provided the collar and cuffs aren't gaping. Otherwise, water will constantly circulate, and they'll quickly get cold.

ION children's sizes

Manera children's sizes (Groms and Toddler)

O'Neill children's sizes

Wetsuit accessories: boots and gloves

ION boots

Insole length, with a tolerance of plus or minus 5 mm according to ION.

Prolimit boots

ION, gloves

Prolimit straight-finger gloves

Prolimit measured these on the Long Finger HS Utility. This same chart applies to the Short and Long Finger HS Mesh, Short Finger HS Utility, Elasto Sealed and Elasto Sealed Skin, Q-Glove X-Stretch, Glove Sealed, and summer gloves (Lycra, H2O, Summer Glove Long Finger).

Prolimit pre-curved finger gloves and mittens

These measurements were taken from the Curved Finger Utility. The same chart applies to Curved Finger and Curved Finger Mesh, Polar 2-Layer, Hydrogen, and mittens (Closed Palm / Direct Grip, Open Palm Xtreme, Cold Water).

Limitations of these charts

• A sizing chart applies to the entire brand, not to each specific model. Even with the same size, a more fitted cut or thicker neoprene will change the feel.
• Mystic and Rip Curl do not publish weight recommendations. Manera doesn't provide chest or waist circumference. For these brands, your height is the primary factor.
• The Ride Engine values are our conversions from inches and pounds.
• Two official charts contain a typo (Prolimit XS women, Billabong XXS women). The note below each table indicates the correct value we used.
