What is a US Women's size Medium in EU?

A US Women's Medium (roughly US size 8–10) corresponds to approximately EU 38–40. Because sizing varies by brand and garment cut, it is always worth checking the brand's own size chart when available.

Are UK and AUS clothing sizes the same?

Not exactly. For women, Australian sizes typically run 2 numbers below their UK equivalent — so AUS 10 ≈ UK 12. For men, AUS and UK sizes are generally interchangeable for most categories.

Why do clothing sizes vary so much between countries?

Sizing systems evolved independently in each country, often based on different body measurement conventions and historical garment-trade practices. There is no international governing body that enforces a single standard.

How to Convert Clothing Size Between US, UK, EU — Free (2026)

By Rui Barreira · Last updated: 18 June 2026

Shopping for clothes internationally—or buying a gift for someone abroad—means navigating a maze of sizing systems that rarely agree with each other. The clothing size converter translates sizes instantly between US, UK, EU, AUS, IT, and FR systems for both men and women.

How to Use the Tool

Select your gender (Women's or Men's).
Choose your current sizing system (e.g. US) and enter your size label (e.g. Medium or 8).
The tool displays the equivalent size in every other system instantly.

How Clothing Size Systems Work

There is no universal clothing size standard. Each country developed its own system, and even within a single country, sizes can vary between brands. The major systems are:

US sizes use letter labels (XS, S, M, L, XL) or numeric labels that differ by gender. Women's US numeric sizes (2, 4, 6, 8…) are entirely different from men's (30, 32, 34… for waist-based sizing).
UK sizes use numeric labels for women (6, 8, 10, 12…) and tend to run roughly 4 numbers above EU for women's tops. A US Women's Medium is approximately UK 12–14 and EU 40–42.
EU sizes use higher numbers (32–46+ for women, 44–62+ for men). They are based on body measurements in centimetres and are used across most of continental Europe.
AUS sizes closely follow UK sizing for women but start 2 numbers lower (AUS 8 ≈ UK 10). Men's AUS sizing typically matches US.
IT and FR sizes are closely related to EU sizes with minor offsets. Italian women's sizes often run 4 higher than EU (EU 40 ≈ IT 44), while French sizing matches EU in most categories.

Use Cases

Ordering clothes from international online retailers (ASOS, Zara, H&M international).
Packing for a trip and needing to shop locally in another country.
Buying a clothing gift for a friend or family member who lives abroad.
Checking whether a secondhand item listed in a foreign size will fit you.
Decoding size labels on vintage or imported garments.
