A quick reference for shopping international brands — sizing still varies by label, so treat this as a starting point.

Result

Converted size: UK 12 / EU 40

A US women's size 8 is roughly a UK 12, EU 40, or M — sizing varies by brand, so treat this as a starting point, not an exact fit guarantee.

Women's clothing sizes across US, UK and EU

US sizes run four numbers below UK, and EU sizes are the US number plus 32.

US	UK	EU	International
0	4	32	XXS
2	6	34	XS
4	8	36	S
6	10	38	S
8	12	40	M
10	14	42	M
12	16	44	L
14	18	46	L
16	20	48	XL

The relationships are arithmetic and easy to remember - UK is US plus 4, EU is US plus 32 - but the sizes themselves are not standardised in any meaningful way. Vanity sizing means a US 8 from one brand can fit like a 6 or a 12 from another, and the drift over decades has been substantial: a modern US 8 is roughly a 1960s US 14. Treat this table as a starting point for ordering internationally, then check the brand's own measurements in centimetres, which is the only figure that means anything consistent.

Sizing isn't standardized across brands

Unlike shoe sizes, clothing size charts vary meaningfully brand to brand and even style to style — always check a specific retailer's own size chart when possible rather than relying purely on a generic conversion.

Vanity sizing shifts over time

Clothing size numbers have drifted smaller over decades (a modern size 8 fits looser than a size 8 from the 1980s) — conversions like this reflect current common charts, not historical ones.

Frequently asked questions

I wear a US size 8 — what's my UK and EU size?

A US women's size 8 is typically a UK 12 and an EU 38. These are approximate — brands like Zara, H&M, and Nike can differ by a size in either direction, so always check the specific retailer's chart.

How is this different from the Shoe Size Converter?

This converts clothing sizes (dresses, tops, pants) between US, UK, and EU systems. The Shoe Size Converter handles footwear sizes, which use completely different numbering scales and have a more standardized measurement (foot length in cm) as a reference point.

Why don't clothing sizes match consistently across brands?

There's no legally enforced standard. Brands set their own size charts based on their target demographic — a size 10 at one retailer may fit like an 8 at another. 'Vanity sizing' (labeling clothes with a smaller number than they'd historically carry) adds more inconsistency.
