5 Simple Tips to Convert CN Shoe Size to US Sizes

Shopping for shoes online from international retailers can be tricky, especially when it comes to sizing. If you’ve ever wondered how to convert CN shoe size to US, you’re not alone. With shoe sizes varying between regions, it’s essential to understand how the Chinese sizing system compares to the US standard.

In this article, we’ll break down the differences and provide easy conversion tips, so you can confidently find the right fit when purchasing shoes from China or other regions that use CN sizes.

How to Convert CN Shoe Sizes to US

Converting CN shoe sizes to US sizes can seem daunting at first, but once you understand the basic principles, it becomes a simple process. Since CN (China) shoe sizes are based on foot length in millimeters, and US shoe sizes follow a different scale, you’ll need a conversion chart or formula to ensure you’re selecting the right size. Here’s a step-by-step guide on how to convert CN sizes to US for men, women, and children, along with practical tips to get an accurate fit.

1. Understanding the Differences Between CN and US Shoe Sizes

The primary difference between the CN and US shoe sizing systems lies in their measurement basis. CN sizes are based on the length of the foot in millimeters, while US sizes are based on an arbitrary number system that corresponds to certain foot lengths. Therefore, direct conversion is not intuitive without a reference chart or specific formula.

For example:

• A CN size 240 corresponds to approximately a US size 6.5 for men or a US size 7.5 for women.
• A CN size 260 would convert to a US size 8.5 for men or US size 9.5 for women.

Since the numbers don’t match up directly between the two systems, understanding the conversion process is critical for ensuring a proper fit when shopping for shoes.

2. Conversion Charts for Men’s, Women’s, and Kids’ Shoes

Using a conversion chart is the simplest and most effective way to convert CN shoe sizes to US sizes. Below are typical conversion examples for men, women, and children:

• Men’s CN to US Conversion Chart:
  • CN 240 = US 6.5
  • CN 250 = US 7.5
  • CN 260 = US 8.5
  • CN 270 = US 9.5
  • CN 280 = US 10.5
• Women’s CN to US Conversion Chart:
  • CN 220 = US 5
  • CN 230 = US 6
  • CN 240 = US 7.5
  • CN 250 = US 8.5
  • CN 260 = US 9.5
• Kids’ CN to US Conversion Chart:
  • CN 120 = US Toddler 5
  • CN 130 = US Toddler 6
  • CN 140 = US Toddler 7
  • CN 150 = US Toddler 8
  • CN 160 = US Kid 9

These charts provide a basic guide for converting CN shoe sizes to US sizes. However, it’s always important to check with specific brands or retailers for any deviations from the standard conversion, as some shoes may vary slightly in sizing.

3. Step-by-Step Guide to Converting CN Sizes to US Sizes

Converting CN shoe sizes to US sizes can be done manually if you know your foot length in millimeters. Here’s a simple process to follow:

1. Measure Your Foot Length: Start by measuring your foot length in millimeters. You can do this by standing on a piece of paper, tracing the outline of your foot, and measuring the distance from the tip of your longest toe to the back of your heel. Use a ruler or tape measure to find the exact length in millimeters.
2. Compare to CN Size Chart: Once you know your foot length, use the CN shoe size system, which is directly based on foot length in millimeters. For example, if your foot is 250 mm, you would be a CN size 250.
3. Convert to US Size: After identifying your CN shoe size, you can then convert it to US sizes using a conversion chart. For example, a CN size 250 typically converts to a US men’s size 7.5 or a women’s size 8.5.

4. Converting Widths and Half-Sizes

One important note is that CN shoe sizes may not account for half-sizes or varying widths as commonly as US sizes do. This means that if you require a specific width (like wide or narrow) or a half-size, you may need to size up or down when converting from CN to US sizes.

• Half-Size Conversions: If you’re between sizes in the US system, rounding up or down to the closest full CN size is typically recommended. For example, if you wear a US men’s size 9.5, a CN size 270 (US 9.5) would be your best match.
• Width Conversions: CN shoe sizing generally doesn’t differentiate between wide and narrow widths, so if you have particularly wide or narrow feet, consider sizing up or down accordingly, or consult the retailer for specific guidance on width.

5. Brand-Specific Sizing Considerations

While the CN shoe size system is relatively standardized, individual brands may have slight variations in sizing. Some brands may run smaller or larger than the standard size charts suggest, so it’s important to check any brand-specific size guides before purchasing.

• Consult Size Guides: Most online retailers will offer a size guide for each specific shoe model, making it easier to find your exact fit. If the brand is known for running small or large, take that into account when converting your CN size to US size.
• Reviews and Feedback: When in doubt, customer reviews can provide valuable insights into how a shoe fits. Look for feedback on whether the shoe runs true to size or if others recommend sizing up or down.

Tools for Accurate Shoe Size Conversion

Converting CN shoe sizes to US sizes is easy with the right tools. Here’s a guide to ensure accurate sizing:
