Enter a CN shoe size to see US, UK and EU equivalents.
Key fact: CN size = EU size. CN 42 = EU 42. No separate formula — find your EU size and that is your Chinese size.
The Chinese shoe size converter converts CN shoe sizes to US, UK, and EU. The sizing used on AliExpress, Taobao, JD.com and by major Chinese brands follows EU numbering directly. There is no offset or formula: CN 42 = EU 42. The most common mistake when ordering from China is treating the CN number as a US size. CN 42 is not US 42 — it is US men's 9.
⚠ Critical: CN 42 ≠ US 42. CN 42 = EU 42 = US men's 9. Ordering CN 42 thinking it is a US 42 will result in a shoe far too small.

Tips for Ordering Shoes from China
- Always check the individual product's size chart — most listings show foot length in CM which is the most reliable reference.
- Read buyer reviews for fit notes — some budget Chinese brands run 0.5 to 1 size small in actual construction even though the CN number is correct.
- When between sizes, size up — returns from China can be slow and expensive.
Frequently Asked Questions
Is CN shoe size the same as EU?
For shopping purposes, yes. The sizes shown on Chinese shopping platforms follow EU numbering, so CN 42 = EU 42. The official Chinese standard (GB/T 3293.1) measures foot length in millimetres instead — for example 260 = 26 cm — and you will sometimes see it on the box.
What CN size should I order for US men's 10?
US men's 10 = EU 43 = CN 43. Do not order CN 10.
Why do some AliExpress listings show size ranges like 39-40?
Some sellers list a size range to indicate one last covers two adjacent sizes. Choose the pair where your size is the lower number for a snug fit, or the higher number for a relaxed fit.
Do Chinese kids' shoe sizes also equal EU?
Generally yes, but always verify using the foot length in CM on the product listing for children's shoes.
