Clothing Size Converter — US / UK / EU / CN / S–XXL for Men & Women

Real-world use cases

• Order from ASOS or Zara without a returns roulette

  You wear a US women's 8 at home and want a dress from a UK retailer that only lists UK and EU sizes. Pick Women's → Dress, set the input system to US, type 8 — the tool returns UK 12 and EU 38, and tells you that size is cut for an ~88 cm bust and ~96 cm hip. Now you measure your own bust at 90 cm and realise you're between the M and L, so you size up for the dress's fitted bodice. That five-second check is the difference between a keeper and a £6 return-shipping fee plus a two-week wait for the refund.

• Buy on Taobao or brief a daigou agent

  A seller lists a men's jacket only as 175/96A and "L". You know your own size as a US 40 suit. Pick Men's → Suit jacket, set input to US, type 40 — you get EU 50, CN 180/100, and the chest range (~102 cm). Compare to the listing's 96A (96 cm chest) and you can see the listing's L runs a touch slim for you, so you message the agent to size up. Copying the CN code straight into the chat means no screenshots, no back-and-forth about which standard you mean.

• Buy clothing as a gift without asking their size outright

  You want to gift a shirt but asking "what's your size?" spoils the surprise. You know they wear a EU 50 in shirts from a label you've seen on them. Pick Men's → Top, input EU, type 50 — you get US/UK L, CN 180/96A, and a ~102 cm chest. Now you can shop any store in any region and match the chest number, even if that store uses a totally different letter scale, instead of gambling on a letter that means something different at every brand.

• Write an international size chart into your product listing

  You're a small brand or a content creator selling merch and your customers are global. Rather than copy a generic chart, run each of your real garment measurements through here and build a listing table that shows US/UK/EU/CN side by side with the chest or waist in cm. Buyers in five regions then self-select correctly, which is the single biggest lever on apparel return rates. Pair it with the unit-converter for any stray inch-to-cm spots in your spec sheet.

• Reconcile a vintage or thrifted label

  A vintage jacket is tagged "EU 48" but vintage European sizing ran smaller than today's. Don't trust the tag — measure the garment's flat chest, double it, and compare to the body columns here. If the EU 48 row says ~97 cm chest but the actual garment measures 88 cm around, you know it'll fit like a modern S, not an M, before you ever try it on.

Common pitfalls

• Reading a letter code across categories. A women's "M" top (~88 cm bust) and a women's "M" trousers (~72 cm waist) are not the same body measurement — the letter only makes sense within one garment type. Always pick the right garment tab before you trust the result.

• Trusting the tag instead of your tape. Because of vanity sizing, the printed number drifts between brands and over the years. Match the chest/waist/hip in centimetres that this tool shows, not the label, especially when mixing a US brand with an EU one.

• Assuming men's and women's numeric systems line up. A men's US 40 (suit, inches of chest) and a women's US 40 do not exist on the same scale — women's US is an even dress-size number. Set the gender first; the whole table changes underneath it.
