Uniqlo Sizing & Fit Guide
Uniqlo uses Japanese sizing, which runs one full size smaller than US sizing. A Japan M = US S. Japan-market garments also have slightly shorter sleeves and hems. Most US shoppers should size up one size when buying from Uniqlo Japan.
View Uniqlo's official size guideDoes Uniqlo Run Small?
Yes — Uniqlo uses Japanese sizing, which runs one full size smaller than standard US sizing. If you wear a US Medium in brands like Gap or Old Navy, you'll likely need a Uniqlo Large. This applies to both men's and women's clothing. The size shift exists because Uniqlo's sizing originates from Japan's JIS standard, where the average body frame is smaller than in the US. In Uniqlo's US stores, they've already adjusted labels (their US Medium is a Japan Large), but if you're ordering from Uniqlo Japan or comparing sizes internationally, always size up one.
How Japan Clothing Sizes Work
Japan uses two sizing systems. Women's clothing uses the 号 (gō) number system: 5, 7, 9, 11, 13, 15, 17 — where 9号 roughly equals a US Small. Men's clothing uses letter sizes similar to the US, but with LL instead of XXL (and 3L, 4L for extended sizes). The key conversion: Japan S = US XS, Japan M = US S, Japan L = US M. Japan sizes are based on JIS (Japanese Industrial Standards) body measurements, which use centimeters. Knowing your chest and waist in cm gives you the most accurate Japan size.
Uniqlo Japan vs. Uniqlo US Store Sizing
Uniqlo adjusts their size labels by market. The same physical garment labeled 'M' in Japan is labeled 'S' in US stores. However, there are also cut differences: Japan-market garments have slightly shorter sleeves (roughly 0.5–1 inch) and shorter hems, designed for the Japanese market. If you're buying directly from Uniqlo Japan (via their Japanese website), size up one from your US Uniqlo size. If you're buying from a US Uniqlo store, the labels are already adjusted — your regular US size should work.
Uniqlo Sizing Tips by Category
T-shirts and basics: the one-size-up rule applies consistently. Outerwear: Uniqlo recommends sizing up one additional size for coats bought from Japan, since they're designed for lighter layering. Jeans and pants: Uniqlo Japan uses waist measurements in cm — a 76cm waist is roughly a US 30. Knitwear: oversized styles are intentionally roomy and may not need the size-up adjustment. Extended sizes (XXL/3XL): only available online in Japan, not in physical stores.
