About Clothing Size Conversions
Clothing sizes vary significantly across countries, and even within a country, sizes differ between brands. This converter uses widely cited average equivalencies — treat the results as a starting point, not a guarantee of fit. When shopping online internationally, always check the brand's own size chart and return policy before ordering.
Women's US numeric sizes follow an even-number progression (0, 2, 4, 6, 8, 10, 12...). EU women's sizes are approximately 30 numbers higher (32, 34, 36, 38, 40...). UK women's sizes sit about 4 numbers higher than US (4, 6, 8, 10, 12...). Japanese women's sizes use odd numbers (3, 5, 7, 9, 11, 13...) that are roughly 3 higher than US. Australian sizes match UK sizes.
Men's suit sizes in the US and UK use chest measurement in inches (34, 36, 38, 40, 42, 44). EU suit sizes are approximately 10 higher than US. Casual wear labels (XS, S, M, L, XL, XXL) are not standardized internationally and vary substantially between brands — for those, always refer to the garment's actual body measurements in inches or centimeters.
Frequently Asked Questions
Is a US size 8 the same as a UK size 8?
No. A US women's size 8 corresponds to approximately UK size 12. UK women's sizes run 4 numbers higher than equivalent US sizes: US 4 = UK 8, US 6 = UK 10, US 8 = UK 12, US 10 = UK 14. US and UK men's suit sizes use the same scale (both measure chest in inches), so US 40 = UK 40.
How do I convert US women's size to EU?
Add 30 to the US size number: US 6 = EU 36, US 8 = EU 38, US 10 = EU 40, US 12 = EU 42. This is a general approximation — actual fit varies by brand, and EU sizing also accounts for height and body proportions differently from US sizing.
What is a US size 8 in Japan?
US women's size 8 corresponds to approximately Japan size 11. Japanese women's sizes generally run 3 higher than US: US 2 = JP 5, US 4 = JP 7, US 6 = JP 9, US 8 = JP 11. Japanese sizes use odd numbers and some brands have their own charts.
Why do clothing sizes vary so much between brands?
Clothing sizes are not standardized by law in most countries — each brand sets its own size patterns according to its target market. A size 8 from one brand may be cut identically to a size 10 from another. 'Vanity sizing' (making numbers smaller over time) has also shifted average size numbers significantly since the 1950s. For international online shopping, always check the brand's actual body measurements.
What is the difference between US and EU men's suit sizes?
US and UK men's suit sizes use chest measurement in inches (34, 36, 38, 40, 42, 44). EU suit sizes are approximately 10 higher: EU 46 = US/UK 36, EU 48 = US 38, EU 50 = US 40, EU 52 = US 42. Drop size (the combination of jacket size and trouser waist) and cut still vary significantly by brand.
