CN Shoe Size Conversion

Why You Need a CN Shoe Size Converter

Shopping for shoes on Chinese e-commerce platforms like AliExpress, Taobao, Tmall, and Shein can be frustrating without understanding CN (Chinese) shoe sizing. Unlike US, UK, or EU sizing systems that use arbitrary numbering, CN sizes are based on direct millimeter measurements of foot length. Our free CN shoe size converter eliminates the confusion by instantly translating Chinese sizes to all major international systems.

The CN sizing system is actually more accurate than Western sizing because it directly measures foot length in millimeters. When you see CN 260, it means the shoe is designed for a foot that measures 260mm (26 centimeters) long. This precision reduces sizing errors and makes it easier to find your perfect fit when shopping internationally.

Understanding Chinese (CN) Shoe Sizing

Chinese shoe sizing is remarkably straightforward once you understand the millimeter-based measurement system. CN sizes typically range from 220-330mm, with women's sizes generally between 220-290mm and men's sizes between 240-330mm. Kids' sizes range from 120-230mm depending on age. CN sizes usually increase in 5mm increments (250, 255, 260, etc.), making it easy to find half sizes.

One major advantage of CN sizing is that it's unisex in terms of measurement—CN 260 represents the same foot length for both men and women. However, when converting to US sizing, you'll get different results: CN 260 equals US Men's 8 but US Women's 9-10, because men's and women's US sizing use different scales.

How to Use This CN Shoe Size Converter

Using our CN shoe size converter is simple and accurate. First, select your gender (men's, women's, or kids'). For kids, choose the appropriate age group as sizing differs for toddlers, little kids, and big kids. Next, select your Chinese (CN) shoe size from the dropdown—these are displayed in millimeters. The converter instantly shows your equivalent sizes in US, UK, EU, AU, and Japanese (JP) systems.

For the most accurate results, measure your foot length before shopping. Stand on a piece of paper against a wall, mark the longest point of your foot, and measure from the wall to the mark in millimeters. This measurement IS your CN size. For example, if your foot measures 255mm, you need CN 255 shoes. Always round up if you're between sizes.

Common CN Shoe Size Conversions

Some of the most frequently searched CN shoe size conversions include: CN 250 = US Men's 7 / Women's 8 = UK 6.5 / 6 = EU 40 / 38.5. CN 260 = US Men's 8 / Women's 9 = UK 7.5 / 7 = EU 41 / 39.5. CN 270 = US Men's 9 / Women's 10 = UK 8.5 / 8 = EU 42.5 / 40.5. CN 280 = US Men's 10 / Women's 11 = UK 9.5 / 9 = EU 44 / 42.

These are standard industry conversions based on foot length measurements. However, individual brands—especially on Chinese marketplaces—may vary slightly. Always check the seller's size chart when available, and read customer reviews about sizing accuracy. Many AliExpress and Taobao sellers include detailed measurement charts in centimeters to help you choose the right size.

Shopping on Chinese Marketplaces with Confidence

When shopping on AliExpress, Taobao, Tmall, or other Chinese platforms, understanding CN sizing is essential. Most sellers list sizes in CN first, with US/EU conversions as secondary information. These conversions aren't always accurate, which is why using a dedicated converter like ours ensures you get the right size.

Pro tips for Chinese marketplace shopping: (1) Always check the seller's specific size chart—some brands run smaller or larger. (2) Read reviews from customers in your country about sizing accuracy. (3) When in doubt, contact the seller and provide your exact foot measurement in centimeters. (4) Consider ordering one size up if you have wide feet, as Chinese shoes sometimes run narrower. (5) Use FitSwapr's virtual try-on to visualize how shoes will look before committing to a purchase.
