The simple rule: For US to China shoe size, just add 1 to 2 sizes for men and women. Men: US size 9 = China size 43. Women: US size 7 = China size 38. For kids, it’s a bit different. But here’s the thing – Chinese sizes are based on foot length in millimeters, not inches. So a China size 43 is roughly 265mm or 10.4 inches. Many Chinese factories actually use EUR sizing, but labeled as ‘China’ on boxes. At places like Soudangkou, we see both.
Why the conversion matters for wholesale buyers
Walking through a wholesale market like Soudangkou, you’ll notice most stalls stock shoes in Chinese sizes. If you’re buying for a US market, you need to convert accurately. But here’s a secret: Chinese sizes often run small. In a Guangzhou market, I’ve seen US size 9 men’s shoes tagged as China size 42 – that’s a full size smaller than the standard conversion. Always ask for foot length in mm and check the insole.
Conversion tables by category
Below are the standard conversions based on Chinese standard GB/T 3293.1-1998. But remember, always try on or measure the insole. Stalls in Soudangkou might have different sizing.
Men’s shoes
| US Size | China Size (mm) | China Size (labeled) | Foot Length |
|---|---|---|---|
| 6 | 245 | 39 | 9.6 in |
| 7 | 250 | 40 | 9.8 in |
| 8 | 255 | 41 | 10.0 in |
| 9 | 260 | 42 | 10.2 in |
| 10 | 265 | 43 | 10.4 in |
| 11 | 270 | 44 | 10.6 in |
Women’s shoes
| US Size | China Size (mm) | China Size (labeled) | Foot Length |
|---|---|---|---|
| 5 | 225 | 35 | 8.9 in |
| 6 | 230 | 36 | 9.1 in |
| 7 | 235 | 37 | 9.3 in |
| 8 | 240 | 38 | 9.4 in |
| 9 | 245 | 39 | 9.6 in |
| 10 | 250 | 40 | 9.8 in |
Kids’ shoes
Kids sizes are trickier. For toddlers, US size 6 = China size 140mm (about 5.5 in). For older kids, US size 3 = China size 215mm (8.5 in). Check the child’s foot length and compare to the mm chart.
How to check fit in a wholesale stall
When you’re in a market like Soudangkou, you can’t rely on labels. Here’s what experienced buyers do: measure the insole – take the shoe’s insole out and measure its length in centimeters. Compare that to the customer’s foot length plus 0.5-1 cm for comfort. Also, feel the materials – cheap shoes will have stiff lining that makes the fit feel smaller. Quality shoes from Soudangkou stalls often use soft cotton lining that molds to the foot.
Expert tips for buying wholesale
- Ask for the ‘mm’ size – Most factories use mm, not US or EU. This removes ambiguity.
- Sample first – Always order one pair in each size to check fit before bulk order.
- Watch for batch variation – Even the same style can vary between production runs. Check each batch.
- Know your market – If you’re selling in the US, consider offering half-size insoles to adjust fit.
FAQ
| Question | Answer |
|---|---|
| Is China shoe size same as EU? | Often yes for labeled sizes, but Chinese standard uses mm internally. A China 43 is usually same as EU 43, but check foot length in mm. |
| Do Chinese shoes run small? | Many do, by about half to a full size. Order up if in doubt. |
| Can I return shoes from Soudangkou if size is wrong? | Depends on the stall. Most will exchange if you catch it quickly, but it’s better to measure before buying. |
| What’s the conversion for women’s US 9? | Usually China 39 or 245mm. But always check the insole. |
Bottom line: When in doubt, measure. Chinese sizing can be inconsistent, especially in wholesale markets. Stick with stalls that provide clear mm measurements and have good return policies. And if you’re ever at Soudangkou, ask the old-timers – they’ve seen it all and can spot a size issue from across the aisle.
