Convert women's clothing sizes from US letter sizes to EU and UK equivalents.
Formula
Conversion is performed via a lookup table keyed on US letter size:
{ EU size range, UK size range, US numeric range } = table[US letter size]
Example: US M → EU 40–42 → UK 12–14 → US numeric 8–10.
How it works
Women's clothing sizes across regions each use different numeric bases with no single arithmetic formula linking them; the converter uses an industry-standard lookup table covering XS through XXL. EU sizes correspond to European chest/bust measurements in centimetres, UK sizes follow a legacy scale roughly 8 below the EU number, and US numeric sizes run 6–8 below UK sizes. All conversions produce size ranges because each letter size spans approximately two numeric steps.
Common mistake: Clothing sizing is not standardised across brands or countries — a brand's EU 42 may fit differently from another brand's EU 42. These conversions give the conventional mapping, but actual fit depends on the brand's specific size chart, the garment's cut, and the wearer's individual measurements (bust, waist, hip). Always check a brand's own size guide before purchasing internationally.
Worked example
Convert women's US size Medium (M) to EU, UK, and US numeric
- Input: US letter size M.
- Look up M in the women's clothing size table.
- Read off: EU = 40–42, UK = 12–14, US numeric = 8–10.
Women's US M = EU 40–42, UK 12–14, US numeric 8–10.
Common mistakes to avoid
- Assuming EU numeric sizes map one-to-one to US numeric sizes -- a US women's size 8 corresponds roughly to EU 38-40, not EU 8.
- Ignoring that size ranges differ by country and brand -- a UK size 12 is roughly a US size 8, but vanity sizing means the same garment can be labelled differently across brands.
- Using a men's clothing size chart for women's clothing -- men's and women's sizing systems use completely different scales and measurements.
Key terms
- US letter size (women's clothing)
- A categorical sizing system (XS, S, M, L, XL, XXL) used predominantly in North America. Each letter corresponds to a range of body measurements rather than a single dimension.
- EU clothing size
- A numeric system based loosely on bust circumference in centimetres. A EU 40 corresponds roughly to an 84 cm bust, with each 2-unit increment representing about 4 cm of additional measurement.
- UK clothing size
- A numeric system where sizes run approximately 8 below the equivalent EU number. A UK 12 corresponds to roughly EU 40. Like EU sizing, it is not fully standardised across all UK retailers.
- US numeric size (women's)
- A numeric counterpart to the US letter system; sizes 0–22 (even numbers) are common for women's apparel. Each numeric size step of 2 represents approximately 1 inch of additional bust/waist/hip measurement.
