How to measure
Two minutes and a tape measure.
- Grab a soft tapeNo tape? Use a phone charger cable or string, then lay it against a ruler.
- Find where your shorts sitThat's usually just below your belly button, not your hip bones.
- Measure flat and snugWrap it level all the way round. Snug, not tight. Breathe normally.
- Match it to the chartBetween two sizes, or right on the line? Go up. They're cut snug.
How they should fit
Snug, flat and staying put.
Waistband
Sits flat with no rolling or digging in. The drawcord is there to fine tune, not to hold up a size that's too big.
Legs and seat
Leg openings sit snug without cutting in. Full seat coverage. If you can pinch spare fabric at the back, size down next time.
Built in
Every pair of men's swim briefs has a full front liner. Our model is 183 cm and wears a 34/L.
Women's one pieces and bikinis come in S (AU 8), M (AU 10) and L (AU 12). Measure bust, waist and hip, and go with the size that fits your largest measurement. Between sizes, go up.
Women's size finder
Fill in any or all three. More measurements, better answer.
| Size | Bust | Waist | Hip | Body loop |
|---|---|---|---|---|
| S / AU 8 | 79 to 83 | 61 to 65 | 87 to 91 | 142 to 152 |
| M / AU 10 | 82 to 88 | 66 to 70 | 92 to 96 | 147 to 152 |
| L / AU 12 | 89 to 93 | 71 to 75 | 97 to 101 | 150 to 155 |
Same chart for one pieces, bikini tops (use bust) and bikini bottoms (use hip and waist). Body loop matters most if you have a long torso.
How to measure
Four measurements, two minutes.
- BustAround the fullest part of your bust, tape level across your back. Wear a non padded bra or nothing.
- WaistAround the narrowest part of your natural waist, usually just above the belly button.
- HipAround the fullest part of your hips and bottom, feet together.
- Body loopFrom the top of one shoulder, down the front, through your legs and up your back to the same shoulder.
Style notes
Thin strap, wide strap or bikini.
Thin vs wide strap
Thin strap one pieces come up a little smaller than our wide strap styles. If you're between sizes in a thin strap, go up.
Bikinis, mix and match
Sold as a set, but you choose the top and bottom size separately. Tops: go with your bra band size, then fine tune with the neck and back ties. Bottoms: your usual undies size; the side ties give room either way.
Built in
Every one piece has removable padding. For laps, a one piece holds better than a bikini. Our one piece model is 157 cm and wears S (AU 8).

Sizing questions
Size guide FAQs
Do Salty Johnson swimmers run small?
They're cut snug for swimming, so they sit closer than shorts or undies. Nearly every fit question we get is from someone who went too small, so if you're between sizes, go up.
Should I order my jeans size in men's swim briefs?
No. Jeans sizes vary a lot between brands. Measure your waist where your shorts sit and use the chart: 28/XS is 70 to 75 cm, up to 36/XL at 90 to 95 cm.
Do thin strap and wide strap one pieces fit the same?
Not quite. Thin strap styles come up a little smaller than wide strap styles, so if you're between sizes in a thin strap, go up.
Can I get a different size bikini top and bottom?
Yes. Bikinis are sold as a set, but you pick the top size and the bottom size separately, for example a S top with a M bottom.
Do you make men's 38 or women's AU 6, 14 and 16?
Not yet. Men's briefs run 28 to 36 and women's styles run AU 8 to 12. For women's sizes, join the size waitlist on any women's product page.
Are the briefs lined, and do the one pieces have padding?
Yes. Every pair of men's swim briefs has a full front liner, and every women's one piece has removable padding.
What if my size is wrong?
Contact us within 30 days of delivery and swap it for another size, subject to stock. For Australian orders we cover standard delivery of the first replacement. Black Friday sale items can be swapped or exchanged for store credit, and Vault items are final sale. Full details are in our returns policy.
