A size 40 shoe in China corresponds to a foot length of 25.0 cm (9.84 inches) – which matches a US men’s 7 or EU size 40. But here’s the catch: Chinese sizes can vary between brands and even between factory batches. If you’re sourcing from wholesale market stalls, you need to understand these nuances to avoid costly returns.
Chinese Shoe Sizing Basics
Chinese shoe sizes are typically based on foot length in centimeters. Unlike US or UK sizes, there’s no complicated conversion – just measure your foot in cm and find the closest Chinese size. The most common range for adults is 34 (22.0 cm) to 48 (30.0 cm).
Size 40 in China vs. International Sizes
Here’s a quick conversion for men’s and unisex shoes:
- China 40 = Foot length 25.0 cm
- US men’s 7 = China 40 (but US 7.5 might be China 41)
- EU 40 = China 40 (closest match)
- UK 6.5 ≈ China 40
For women, a China size 40 is rare – it’s equivalent to US women’s 9.5–10. Most Chinese women wear sizes 36–39. If you need women’s size 40, look for unisex styles or men’s options.
Why You Need to Be Careful at Market Stalls
When buying from wholesale market stalls, sizing inconsistencies are common. Here’s what to look for:
- Check the insole length – Always ask to measure the insole in cm. A size 40 shoe should have a 25 cm insole, but some may be 24.5 or 25.5.
- Feel the fabric – Stretchy materials like knit can accommodate half sizes; rigid leather may not.
- Examine stitching – Poor stitching often leads to sizing variance. Look for tight, even seams.

Tips for Buying Size 40 at Wholesale
When sourcing from Chinese wholesale markets, prioritize stalls that show actual product samples. Ask for the exact insole length and material specs. If you’re dealing with leather shoes, note that they may stretch over time. For synthetic materials, what you see is what you get.
