Uniqlo size chart & fit
Uniqlo uses Japanese sizing which runs slim. US shoppers typically size up one full letter (US M → Uniqlo L).
Sizing philosophy
Japanese basics — minimal, precise, engineered fabric. Sizes are consistent across the catalogue but shifted one letter smaller than US expectations.
How Uniqlo shoes fit
Uniqlo shoes are limited (canvas slip-ons); true to size.
How Uniqlo clothing fits
Women's: US size + 1 letter. US S → Uniqlo M. Men's: US S → Uniqlo M for regular fit; oversized styles run true. HEATTECH and AIRism base layers fit tight — size up.
Width & last
Slim standard across the line.
