How to Measure for Gymshark
Take measurements over lightweight underwear. Use a soft, flat tape measure — not elastic — and keep it level and snug but not tight.
- →Bust / Chest: Measure around the fullest part of your chest, keeping the tape parallel to the floor. For men, include the widest point across the shoulder blades.
- →Waist: Measure around your natural waist, approximately 2–3 cm above the navel. Stand relaxed — do not suck in.
- →Hips: Measure around the fullest part of your hips, approximately 20 cm below the natural waist. Essential for getting leggings and shorts right.
- →Tip for leggings: For Gymshark leggings, use your hip measurement as the primary guide. Their leggings are cut narrow through the hip — if in doubt, size up.
Gymshark vs Other Activewear Brands
Gymshark S = Nike M = Adidas M = Lululemon S (EU). If you wear M in Nike, order L in Gymshark. Here is a quick comparison for women's activewear:
| EU size | Gymshark | Nike | Adidas | Lululemon | H&M Sport |
|---|---|---|---|---|---|
| EU 34 | XS | XS | XS | XS | XS |
| EU 36 | S | XS–S | XS–S | S | S |
| EU 38 | M | S | S | S | S |
| EU 40 | L | M | M | M | M |
| EU 42 | XL | L | L | L | L |
| EU 44 | XXL | XL | XL | XL | XL |
Nike and Adidas follow EU sizing closely, so their S corresponds to EU 36–38. Gymshark's S corresponds to EU 36 only — meaning you need to size up one step from any of these brands when switching to Gymshark.
