Convert clothing sizes: EU ↔ US ↔ UK for women, men & shoes
Shopping internationally has never been more popular, but figuring out the right clothing size across different systems can be a real headache. Our free Clothing Size Converter instantly translates sizes between EU, US, and UK standards for women, men, and shoes — no more guesswork, no more expensive returns.
Clothing size systems evolved independently in different countries, based on varying body measurement standards and manufacturing traditions. A EU size 40 for women is not the same as a US size 40 — in fact, it corresponds to a US size 10 and a UK size 12. This disconnect causes confusion for millions of online shoppers every day.
The problem is compounded by the fact that even within a single country, brands may size their garments slightly differently. However, standardized conversion tables provide an excellent starting point that dramatically reduces the risk of ordering the wrong size.
Using our tool is straightforward:
Results appear in real time, making it perfect whether you're browsing an American fashion website, ordering from a British retailer, or shopping on a European platform. No registration required.
Women's sizing is one of the most inconsistent areas in fashion. European sizes for women typically start at EU 32 (XS) and go upward in increments of 2. US sizes begin at 0 or 2, while UK sizes generally run 4 numbers lower than EU sizes.
Real-world example: A woman who wears a size 38 in Germany is shopping on an American website. Our converter immediately tells her she should be looking for US size 8 and would wear a UK size 10 in British stores.
Men's sizing works differently depending on the garment type. Dress shirts are sized by collar circumference — centimetres in EU, inches in US/UK. Trousers are measured by waist and inseam length, with American jeans typically labelled in inches.
Example: A man with a EU collar size 41cm needs a US/UK collar size of 16 inches. Our converter handles jackets, suits, casual tops, and trousers with equal ease, giving you confidence when shopping across borders.
Shoe sizing is arguably the trickiest area of all. Not only do EU, US, and UK systems differ, but within the US system, women's and men's shoe sizes are calibrated differently. A EU shoe size 38 equals a women's US 7.5 and a UK 5, yet the same EU size maps differently for men.
If you're hunting for the latest sneaker release on an international website, always convert your shoe size first. Our tool accounts for gender-specific differences automatically, saving you time and money.
Even with accurate size conversions, keep these tips in mind:
Our Clothing Size Converter on Simple Calculator is completely free to use, works on any device — mobile, tablet, or desktop — and requires no login or app download. It's regularly updated to reflect current international sizing standards, giving you reliable results every time.
The converter supports EU, US, and UK sizing for women's clothing, men's clothing, and shoes — covering the most widely used systems worldwide.
Conversions are based on internationally recognized standard tables. Since individual brands may cut their garments differently, we recommend also checking the specific brand's measurement guide for the best fit.
Currently, the converter focuses on adult sizes for women, men, and shoes. A children's clothing size extension is planned for a future update.
The US developed separate sizing scales for men's and women's shoes historically. The difference is typically around 1.5 sizes, which is why our converter asks you to specify the category before converting.
