Accurate answers to the most common international clothing size questions.
Shopping from overseas retailers like ASOS (UK), Zara (Spain), H&M (Sweden), Uniqlo (Japan) or Amazon Fashion is easier than ever — but getting the right size remains the biggest source of returns and frustration. A US size 6 is not the same as a European size 6, and a UK 12 is not the same as a US 12.
To convert a US size to EU for women, add 32 to the US size: US 4 = EU 36, US 6 = EU 38, US 8 = EU 40, US 10 = EU 42, US 12 = EU 44. This is a general guide — vanity sizing means actual fit varies between brands. Always check the brand's size chart alongside the conversion.
UK women's sizes are 4 higher than US sizes: UK 8 = US 4, UK 10 = US 6, UK 12 = US 8, UK 14 = US 10, UK 16 = US 12. For men's clothing, UK and US sizes are the same. For women's shoes, US sizes are 2 higher than UK (US 8 = UK 6).
Japanese women's clothing sizes use a numeric scale from 5 to 25. Japanese size 9 is roughly equivalent to US 4, UK 8 and EU 36. Japanese sizing runs smaller than Western sizing — sizing up by one is the standard recommendation for brands like Uniqlo, MUJI, Comme des Garçons and other Japanese labels.
Men's suit sizes are based on chest circumference. US and UK chest sizes are identical (40-inch chest = size 40 in both). European suit sizes are approximately 10 higher than US (US 40 = EU 50). Italian sizes align with EU. Japanese suit sizes use S/M/L/XL labels rather than numbers.
French women's clothing sizes are 4 higher than standard EU: EU 36 = FR 40, EU 38 = FR 42. This is a common source of confusion when shopping from French brands like A.P.C., Sandro or Rouje. Italian sizes use a different scale again — EU 36 = IT 40. SizeConverter lists French and Italian sizes as separate columns in every chart.
