Quick answer
To find your correct swim brief size, measure your natural waist at the narrowest point and your hips at the widest point, then compare both to the brand's size chart. Always prioritize the larger measurement if you fall between sizes.
Why sizing matters for swim briefs
Swim briefs rely on a snug, supportive fit to stay secure in the water. A size too large can sag or slip, while a size too small may dig in or feel restrictive. Unlike casual underwear, swim briefs are designed to hold their shape when wet, so getting the right measurement is essential for comfort and confidence.
Brand variation and size charts
Each brand may use slightly different sizing standards. For example, the JOR 2193 Mystic Swim Briefs and the Clever Moda 2066 Malpelo Swim Briefs both recommend referring to their specific size chart before ordering. Always check the chart for the exact product you're buying rather than assuming your usual pant size translates directly.
Step-by-step swim brief sizing guide
- Measure your waist: Use a soft measuring tape around your natural waist — the narrowest part of your torso, usually just above your belly button. Keep the tape snug but not tight. Write down the measurement in inches. A common mistake is measuring over clothing or at the pants waistline, which can add an inch or more.
- Measure your hips: Stand with your feet together and measure around the fullest part of your hips and buttocks. This is especially important for swim briefs because the seat needs enough room to move comfortably. If your hip measurement is larger than your waist, use the hip size as your primary reference for choosing the brief size.
- Compare with the size chart: Find the size chart for the specific swim brief you want. Match your waist and hip measurements to the listed ranges. If you fall between two sizes, choose the larger one — you can always tighten the drawstring for a more secure fit. Never assume your jeans size equals your swim brief size; swimwear is cut closer to the body.
- Check the fit before wearing: Once your briefs arrive, try them on briefly without tags. The waistband should sit flat without rolling, and the leg openings should grip without leaving deep marks. Raise your arms and squat — the briefs should stay in place without shifting. If the fabric wrinkles or sags at the back, the size is too large. If the leg elastic digs in or the front feels compressed, size up.
