Understanding International Clothing Sizes
International clothing sizes can be confusing because there is no universal standard. The US uses numerical sizes for women (0-20+) and letter or numerical sizes for men. The UK has its own numbering system. European sizes use a centimeter-based system, while Japanese sizes tend to run smaller than Western equivalents.
This converter covers tops, shirts, pants, trousers, and dresses across five major sizing systems: US, UK, EU, Japan (JP), and Australia (AU). For women, US and UK sizes differ by about 4 (US 8 = UK 12), while EU sizes differ by about 30 (US 8 = EU 38). Australian women's sizes are the same as UK sizes.
Keep in mind that sizing varies between brands, and even within the same brand, different styles may fit differently. Always check brand-specific size charts when shopping online. Taking your body measurements (bust, waist, hips, inseam) and comparing them to the brand's measurement guide will give you the most accurate fit.
Frequently Asked Questions
How do I convert between US and European clothing sizes?
For women, subtract 30 from the EU size to approximate the US size (EU 38 = US 8). For men's suits/shirts, EU sizes are typically about 10 higher than US sizes (US 40 = EU 50). These are approximate conversions that can vary by brand.
Are UK and US clothing sizes the same?
No. For women, UK sizes are typically 4 less than US sizes (US 8 = UK 12). For men, UK and US shirt letter sizes (S/M/L) are generally the same, but numeric sizes for suits differ.
What does S, M, L, XL mean in different countries?
Letter sizes (S, M, L, XL) are widely used globally but the actual measurements vary between brands and countries. A US Medium may fit like a European Large. Asian sizes tend to run smaller than Western sizes.
How do Japanese clothing sizes compare to US sizes?
Japanese sizes tend to run 1-2 sizes smaller than US sizes. A US Medium is approximately a Japanese L or LL. For numbered sizes, a JP 9 in women's clothing is roughly a US 4-6.
