Measurements from Gymshark’s official women’s size guide, updated August 2026. The same chart covers leggings and shorts.
How to measure
- Waist — around the narrowest part of your waist, usually just above your belly button. Snug, not tight.
- Hips — around the fullest part of your hips and bum. This is where leggings stretch the most, so if your waist and hip sizes differ, go by your hip.
- Inside leg — from the crotch to your ankle. Use this to choose between short, regular and long lengths.
Leg lengths
| Leg length | Inside leg | Gymshark suggests it for heights of |
| Short | 72.5cm | about 4′2″ – 5′5″ |
| Regular | 77.75cm | about 5′5″ – 5′9″ |
| Long | 82.5cm | about 5′9″ – 6′5″ |
Sizing pre-owned Gymshark
Every pre-owned piece is sold by the size on its label. Two things are worth knowing:
- Grade AB pieces can show minor fabric relaxation, so if the fit matters to you, ask us for the measurements of the exact pair before you pay.
- Buying for resale or in bundles? Tell us your size breakdown — for example, mostly S and M — and we’ll match it as closely as stock allows.
Lululemon uses different (US numeric) sizing — see our Lululemon size guide if you’re buying both.
