China (CN) to US Shoe Size Converter
Easily convert China (CN) shoe sizes to US sizes for men, women, and kids. Our tool uses standard charts and includes foot measurement guides (CM/MM) for better accuracy when converting between CN and US shoe sizing systems.
China (CN) to US Shoe Size Conversion Tool
Select shoe type, then enter your China (CN) shoe size or US size. For the most accurate conversion, use your foot length in Millimeters (MM) or Centimeters (CM), as Chinese sizing can be inconsistent.
Results use standard conversions. Brand sizing varies significantly! For converting CN sizes, using MM or CM foot length provides the most reliable US size estimate, as CN sizes can be based on Millimeters (like KR/Mondopoint) or resemble EU numbers.
How to Measure Feet Accurately (+ Printable Tool)
Precise foot length (CM/IN/MM) is crucial for accurate shoe size conversion, especially when converting Chinese (CN) sizes to US or comparing brands.
Measurement Steps:
- Gather Supplies: Find a hard floor, a wall, a piece of paper larger than your foot, a pen or pencil, and a ruler or tape measure (with CM & IN).
- Position Foot: Place the paper on the floor against the wall. Stand on the paper with your heel firmly against the wall. Wear the type of socks you'd normally wear with the shoes. Ensure your weight is evenly distributed.
- Trace Outline: Have someone else trace the outline of your foot, keeping the pen held vertically (at a 90° angle) to the paper. If alone, trace carefully, ensuring the pen stays snug against your foot.
- Measure Length: Remove your foot. Draw a straight line from the back of the heel mark to the tip of the mark for your longest toe. Measure this line using your ruler in both **Centimeters (CM)** and **Inches (IN)**. Note the Millimeters (MM) too (CM * 10).
- Repeat for Other Foot: Feet are often slightly different sizes. Repeat steps 2-4 for your other foot.
- Use the Longer Measurement: Always use the measurement from your *longer* foot for conversion. Enter this CM, IN, or MM value into the converter tool above. This is especially important for CN sizes which might be MM-based.
- Consider Comfort Room: Most size charts account for *shoe* length, not exact foot length. Unless a brand guide says otherwise, add about 1cm (approx. ⅜ inch) to your foot measurement *before* comparing to size charts to allow for necessary wiggle room.

Brand-Specific Shoe Sizing Guides (for US sizes)
After converting your CN size to an estimated US size, remember that US sizing can vary significantly between brands! Always check the brand's official size chart before making a purchase.
-
Nike Sizing: Generally true-to-size for many models, but some styles might run slightly small (~0.5 US size). Check their CM/MM measurements if available.
-
Adidas Sizing: Often fits true-to-US-size. Compare their UK, EU, and JP (which usually corresponds to CM/Mondopoint) sizing on their charts.
-
New Balance Sizing: Known for offering multiple widths. Generally true-to-US-size in length. CM/MM charts are helpful.
Shoe Fit Tips & Common Considerations for US Sizing
Achieving the perfect shoe fit involves more than just converting numbers. Consider these tips when selecting US shoe sizes:
- Time of Day Matters: Measure your feet at the end of the day when they are likely to be slightly swollen for the most accurate sizing.
- Consider Socks: Always measure your feet wearing the type of socks you intend to wear with the shoes.
- Check Both Feet: Most people have one foot slightly larger than the other. Always size based on the larger foot.
- Allow Wiggle Room: Ensure there's about a thumb's width (approx. ½ inch or 1-1.5cm) of space between your longest toe and the end of the shoe.
- Width is Important: Standard US widths vary (Men's D/M, Women's B/M). If converting from CN, be aware width might not directly translate.
China (CN) to US Shoe Size Converter FAQ
What's the best way to convert my CN shoe size to US?
The most reliable method is to measure your foot in Millimeters (MM) or Centimeters (CM). Enter this measurement into the "MM (Foot/Mondo)" or "CM (Foot)" field in our converter. Chinese (CN) shoe sizes are inconsistent; some directly use MM (e.g., CN 245 = 245mm), while others resemble EU sizing. Relying on your foot length is more accurate than just a CN number for US conversion.
How do CN (Chinese) shoe sizes generally convert to US?
There's no single rule due to CN sizing inconsistency.
- If the CN size is a 3-digit number (e.g., 240, 255), it's likely Millimeters (MM). Use this in the "MM (Foot/Mondo)" field.
- If the CN size is a 2-digit number (e.g., 38, 42), it often aligns with EU sizing. You can try entering it as "CN Size" in our tool, which considers this possibility.
- Always prioritize foot measurement (CM/MM) for the best US conversion.
How accurate is this CN to US shoe size converter?
This tool uses standard international conversion data. It's a good guideline, especially if you input your CM/MM foot length. However, because CN sizing itself varies and US brand sizing also differs, always verify with the specific brand's US size chart after getting an estimate.
How does the Men's to Women's shoe size conversion work for US sizes?
The standard rule of thumb for US sizes is: **US Women's Size = US Men's Size + 1.5**. Conversely, US Men's Size = US Women's Size - 1.5. Use the dedicated Men's↔Women's converter section above for quick US conversions once you have an initial US size.
What is Mondopoint sizing and how does it relate to CN sizes?
Mondopoint is an international standard based on **foot length in Millimeters (MM)**. Some Chinese (CN) shoe sizes, particularly for athletic or specialized footwear, use this system directly (e.g., CN 265 = 265mm foot length). Our "MM (Foot/Mondo)" input field is for this.
Final Sizing Disclaimer (CN to US)
This China (CN) to US shoe size converter, charts, and guides are provided as reference tools only. Sizing standards vary significantly for CN sizes and also between US brands.
Always prioritize measuring your foot accurately (CM/MM) and consulting the specific brand's official US size chart and fit recommendations before purchasing footwear. Relying solely on number conversion may lead to an incorrect fit.
