China uses its own shoe sizing system, often labeled as ‘CN’ or simply a number (e.g., 39, 40). Unlike US or UK sizes, Chinese sizes are typically based on foot length in millimeters. For example, CN 39 corresponds to a foot length of about 245mm.
How Chinese Shoe Sizes Work
In Chinese wholesale markets, you’ll mostly see numbers like 39, 40, 41, etc. These are roughly equivalent to European (EU) sizes, but there are nuances. Chinese sizing is generally more aligned with EU, but it can run slightly smaller or narrower. Always check the foot length (in mm) on the insole or ask the supplier.
Conversion Chart: China vs US, UK, EU
| CN Size | Foot Length (mm) | US Men | US Women | UK | EU |
|---|---|---|---|---|---|
| 38 | 240 | 6.5 | 7.5 | 5.5 | 38 |
| 39 | 245 | 7 | 8 | 6 | 39 |
| 40 | 250 | 7.5 | 8.5 | 6.5 | 40 |
| 41 | 255 | 8 | 9 | 7 | 41 |
| 42 | 260 | 8.5 | 9.5 | 7.5 | 42 |
| 43 | 265 | 9 | 10 | 8 | 43 |
| 44 | 270 | 9.5 | 10.5 | 8.5 | 44 |
Tips for Wholesale Buyers in China
When sourcing from Chinese wholesale markets, always request size charts directly from suppliers. Many factories produce shoes in standard CN sizes but can adjust for overseas orders. Here are some practical tips:
- Check the insole: Remove the insole and measure its length in mm. That’s the most reliable sizing.
- Ask about width: Chinese shoes tend to be narrow. If your market needs wide sizes, confirm with the supplier.
- Order samples: Before bulk orders, get sample pairs to test fit.
- Know your market: For US buyers, typically add 1-1.5 sizes to US women’s and 0.5-1 sizes to US men’s.

Real Talk: What Soudangkou Buyers Know
From my experience walking the aisles at Soudangkou, the best tip is to talk to the stall owner directly. They handle thousands of pairs and know exactly how their sizes fit. A knowledgeable supplier will tell you: “This style runs big, order one size down.” Trust that street smarts.
Why Foot Length Matters More Than Size Number
Every reputable Chinese shoe factory stamps the foot length in mm on the box. That 245mm (CN 39) is your universal truth. When comparing with US sizes, remember that US men’s and women’s sizing are different; a US women’s 8 is CN 39, while a US men’s 8 is CN 41. Always convert using foot length, not just label.
Quality Check: Sole and Stitching
In wholesale markets, you’ll see shoes at various price points. High-quality Chinese shoes have clean, even stitching and thick, odor-free soles. If the insole is removable, check the glue quality. A good indicator: press down on the heel – no squeaks or gaps. This matters more than size numbers.
For a reliable sourcing experience, platforms like Soudangkou connect you with verified wholesalers. Many will provide size charts in both CN and your target market’s sizing. The key is to communicate clearly: specify foot length in mm, not just “size 8”.
Final Checklist for Importers
- Always request a size chart in mm.
- Order samples in 2-3 sizes covering your range.
- Ask about half sizes – not all Chinese factories offer them.
- Convert sizes for your market using foot length, not assumptions.
China’s shoe sizing is logical and consistent once you understand the millimeter system. Whether you’re buying from Soudangkou or elsewhere, this knowledge will save you returns and keep your customers happy.
