Fit Guide

Compression Fit

Designed to feel tight and supportive. If you prefer a less compressive feel, size up.

Performance

True to Size

Most Gymshark leggings and tops are designed to fit true to size for a body-fit silhouette.

Standard Fit

Seamless Technology

Seamless styles adapt to your shape. If you are between sizes, choose the larger size for comfort.

Flexibility

How to Measure

Chest / Bust

Measure around the fullest part of your chest or bust, keeping the tape level under your arms and across your back.

Waist

Measure around the narrowest part of your waist, usually just above your belly button.

Hips

Stand with your feet together and measure around the fullest part of your hips and seat.

Inseam

Measure from the crotch down to your ankle bone, or use a pair of leggings that fit you well.

Fit Note: Gymshark activewear is designed for a performance fit. Compression styles will feel tighter than relaxed styles. If you are between sizes, we recommend sizing up unless you prefer a very snug fit.

All measurements are in centimeters. For best results, measure yourself over lightweight clothing or underwear. Keep the tape snug but not tight.
