Convert clothing sizes between US, UK and EU for men\
What Is Clothing Size Converter?
Clothing sizes vary enormously between countries and even between brands within the same country. A UK size 12 corresponds roughly to a US size 8 and an EU size 40, but the exact measurements differ. Adding to the confusion, different brands interpret sizes differently — one brand's "medium" may be another's "large". This inconsistency makes international shopping, especially online, a frustrating guessing game.
This converter maps between UK, US and EU sizing for men's and women's tops and bottoms, and provides the nearest equivalent sizes across systems to help you choose the right size when shopping from international retailers.
Premium adds general measurement-taking tips, and a kids' sizing reference — UK/EU children's clothing is standardly labelled by age with a height range, so instead of guessing a specific numeric conversion, it maps age directly to the height range you should check your child against.

Tips & Best Practices
Size charts are more reliable than size labels — check the chest, waist and hip measurements in centimetres.
US women's sizes are typically 4 numbers smaller than UK sizes (UK 12 ≈ US 8).
EU sizes use a different numbering system entirely — a UK 10 is roughly an EU 38.
Asian sizing (Japan, Korea, China) tends to run smaller than Western sizing — size up by 1–2 sizes.
