US to UK Size Conversion Chart — Clothes & Shoes (2026)

US, UK and EU clothing sizes differ by fixed offsets — once you know them, shopping internationally stops being guesswork.

Women's clothing

US 0 = UK 4 = EU 32 · US 2 = UK 6 = EU 34 · US 4 = UK 8 = EU 36 · US 6 = UK 10 = EU 38 · US 8 = UK 12 = EU 40 · US 10 = UK 14 = EU 42 · US 12 = UK 16 = EU 44. Rule: UK = US + 4, EU = US + 32.

Men's clothing

Men's US and UK sizes are the same for suits and shirts (chest in inches). EU = US + 10: US 38 = EU 48, US 40 = EU 50, US 42 = EU 52.

Women's shoes

US 6 = UK 4 = EU 36.5 · US 7 = UK 5 = EU 37.5 · US 8 = UK 6 = EU 38.5 · US 9 = UK 7 = EU 40 · US 10 = UK 8 = EU 41. Rule: UK = US − 2.

Men's shoes

US 8 = UK 7 = EU 41 · US 9 = UK 8 = EU 42 · US 10 = UK 9 = EU 43 · US 11 = UK 10 = EU 44.5 · US 12 = UK 11 = EU 46. Rule: UK = US − 1.

Measure instead of guessing

Bust, waist and hip in cm beat any size label. Women's UK 12 ≈ 91 cm bust, 74 cm waist, 99 cm hip; sizing charts vary between brands by a full size.

Vanity sizing warning

The same nominal size has grown 3–5 cm in the waist since the 1990s at many retailers. Always check the brand's own centimetre chart before ordering.

How this guide is researched and fact-checked

This article is produced by the ToolKit Pro Measurement Desk using ai-assisted research with human editorial verification against primary sources, and is checked by a human editor at the ToolKit Pro editorial desk before publication. Every number, formula and threshold quoted here is traced back to a primary standards body or health authority rather than to another blog, and each figure is re-computed with our own calculators so the worked examples and the live tools on this site always agree. When a definition changes — as with the 2019 SI redefinitions — the affected articles are re-checked and the “updated” date above is bumped.
