Size & inseam guide
Waist, chest and head measurements, and what 5, 7 and 9 inches of inseam actually look like.
Last updated: 28 September 2026
Inseam
The inseam is the seam on the inside of the leg, from the crotch to the hem. Every swim short comes in three: the shorter the inseam, the more thigh you show. Our photos show the 7-inch.
| Inseam | Length | Where it sits (average height) |
|---|---|---|
| 5″ | 12.7 cm | Well above the knee |
| 7″ | 17.8 cm | Mid-thigh |
| 9″ | 22.9 cm | Just above the knee |
How to measure
- Waist: measure around your natural waist, where you wear your shorts, keeping the tape level and relaxed.
- Chest: measure around the fullest part of your chest, under your arms.
- Head: measure around your head just above the ears and eyebrows.
- Inseam of shorts you already own: lay them flat and measure the inside leg seam from the crotch to the hem.
