Buying shoes across borders can feel like a gamble. A “size 40” in China doesn’t line up perfectly with a “size 9” in the US or a “size 6” in the UK, and that’s before you factor in European sizes that follow a completely different system. For international shoppers, one wrong number often means shoes that pinch, slip, or end up sitting in the back of the closet.
That’s why understanding shoe size conversion is so important. Whether you’re ordering sneakers from the US, dress shoes from Europe, or casual flats from China, knowing how to translate between China, US, UK, and EU sizes can save you time, money, and frustration. This guide breaks down the differences between sizing systems, shares practical conversion tips, and includes easy-to-read charts so you can find the right fit every time.
Understanding Different Shoe Size Systems
When it comes to buying shoes internationally, the numbers on the label can be confusing. A Chinese shoe size, a US size, and a UK size might all look similar, but they are based on different measurement systems. Understanding these differences is the first step toward making sense of shoe size conversion.
China Shoe Size (CN)
China uses a system based mainly on foot length, usually measured in millimeters. For example, a common men’s size 42 in China represents a foot length of around 260 mm. This makes it easy to match the shoe to your actual measurement, but when you look for china shoe size to US comparisons, you’ll notice the conversion is not always straightforward. That’s because US sizes are built on a different scale.
US Shoe Sizes (US)
The US system is one of the most widely used worldwide, especially for sports shoes and sneakers. Men’s and women’s shoes follow separate charts. For example, a US men’s 9 equals about 42 in EU sizes, while a women’s 9 is closer to 40 EU. Many shoppers also search for US to EU shoe size conversions because brands like Nike, Adidas, and New Balance often list both systems on their labels
UK Shoe Sizes (UK)
The UK system looks similar to the US, but it runs about half a size smaller. A men’s UK 8 is roughly the same as a US 8.5. This difference may seem small, but it matters when you’re ordering online. Many buyers look up UK to US shoe size charts to avoid confusion. In children’s shoes, the gap can feel even larger, so checking a conversion chart is essential.
EU Shoe Sizes (EU)
European shoe sizes, or “Paris points,” increase in steps of about 6.67 mm. This makes the EU system more linear, but it can still cause trouble when you’re switching between regions. For example, a US men’s 10 is usually EU 43 or 44, depending on the brand. That half-size gap explains why some shoes feel just a little too tight or too loose.
Each system has its own logic. Chinese shoe sizes are based on foot length. US and UK sizes use a unit scale that doesn’t directly reflect centimeters. EU sizes are based on increments of Paris points. That’s why no single formula works for all shoes. A reliable chart and a basic understanding of these systems can make a big difference when shopping across borders.
Tips for Converting Shoe Sizes Across China, US, UK, and EU
Converting shoe sizes between China, US, UK, and EU can feel tricky at first. Each region follows its own system, and the numbers don’t always match directly. But with the right approach, you can avoid confusion and find the best fit no matter where you shop.
- Always Use a Conversion Chart: The simplest way to convert is by checking a reliable conversion chart. For example, a Chinese shoe size 39 usually equals a US men’s 7 or a US women’s 8. In the UK system, that would be a size 6, and in EU terms, still a 39. Charts make these connections clear at a glance.
- Watch Out for Gender Differences: Shoe sizes differ for men and women. A US women’s size 8 does not equal a US men’s size 8. In fact, it’s closer to a men’s 6.5. The same applies when converting from UK to US shoe size or US to EU shoe size. Always double-check whether the chart separates men’s and women’s categories.
- Consider Brand and Style Variations: Not every brand follows the standard rules. Some Chinese shoe size charts run slightly smaller, especially for fashion brands. Sports brands may fit larger. Reading reviews or asking sellers about the fit can save you from ordering the wrong size.
- Measure Your Feet for Accuracy: Numbers on a label don’t tell the whole story. The best way to reduce mistakes is to measure your feet. Use a tape measure to check the length in centimeters. Most conversion charts are based on foot length, so this gives you the most accurate result. For example, a foot length of 25 cm often equals China 40, US men’s 7.5, or EU 40.
- Pay Attention to Half Sizes: Not every region uses half sizes. US shoe sizes often include halves, like 8.5 or 9.5, while many China and EU charts skip them. If you’re between sizes, round up when converting from china shoe size to us, and consider adding an insole for a better fit.
- Use Digital Tools: Many online stores now offer interactive converters. Simply enter your current size, and the system suggests the matching size in another region. These tools are especially useful when switching between uk to us shoe size or us to eu shoe size.

Common Problems & Misconceptions About Shoe Sizes
Even with charts and guides, many people still face confusion about shoe sizes. The problem is not only the numbers but also the myths around them. Let’s look at the most common mistakes and misconceptions.
1. Believing All Brands Follow the Same Standard
One major misconception is that all shoes of the same size will fit the same. This is rarely true. A China shoe size 39 may match a US men’s 7 on paper, but some brands run smaller or larger. Always check the specific brand’s chart.
2. Ignoring Foot Width
Most conversion charts only focus on length. But width matters just as much. A perfect UK to US shoe size conversion may still feel tight if your feet are wider than average. Some brands offer wide or narrow options, so don’t forget to consider width.
4. Relying Only on Your “Usual Size”
People often order shoes online using the size they always wear. But sizing can change between regions. A US women’s 8 is not the same as an EU 39, and it’s definitely not equal to a Chinese 39. Your usual size is only a starting point, not a guarantee.
5. Overlooking Kids’ Growth
Parents often buy shoes that fit “just right.” But kids’ feet grow fast. A China kids’ shoe size that fits today might be too small in two months. When shopping internationally, it’s better to size up slightly for children.
7. Misreading Half Sizes or Unisex Sizing
Some people confuse men’s and women’s charts. A US 8 in men’s is not the same as a US 8 in women’s. And unisex sizes often follow men’s sizing, which can mislead buyers if they don’t check carefully.
Shoe Size Conversion for Popular Brands
Even when you know the basics of shoe size conversion, things can get tricky with popular brands. Each brand may follow slightly different sizing standards. A China shoe size to US conversion might look perfect on paper, but the actual fit can still vary depending on the brand’s design, style, and target market.
That’s why it helps to check brand-specific guidelines. Below are some quick references for well-known global brands.
Nike Shoe Size Conversion (Men & Women)
| Foot Length (cm) | China (CN) | US Men | US Women | UK | EU |
| 24.0 | 38 | 6 | 7.5 | 5.5 | 38 |
| 25.0 | 40 | 7 | 8.5 | 6.5 | 40 |
| 26.0 | 42 | 8 | 9.5 | 7.5 | 42 |
| 27.0 | 44 | 9 | 10.5 | 8.5 | 44 |
Nike often runs slightly smaller, so if you are between sizes, it’s safer to go up half a size.
Adidas Shoe Size Conversion (Men & Women)
| Foot Length (cm) | China (CN) | US Men | US Women | UK | EU |
| 24.0 | 38 | 6 | 7 | 5.5 | 38 |
| 25.0 | 40 | 7 | 8 | 6.5 | 40 |
| 26.0 | 42 | 8 | 9 | 7.5 | 42 |
| 27.0 | 44 | 9 | 10 | 8.5 | 44 |
Adidas shoes tend to have a roomier fit compared to Nike. Many buyers say they feel more true to size.
Converse Shoe Size Conversion (Unisex)
| Foot Length (cm) | China (CN) | US Men | US Women | UK | EU |
| 24.0 | 38 | 6 | 8 | 5.5 | 38 |
| 25.0 | 40 | 7 | 9 | 6.5 | 40 |
| 26.0 | 42 | 8 | 10 | 7.5 | 42 |
| 27.0 | 44 | 9 | 11 | 8.5 | 44 |
Converse uses unisex sizing. This often causes confusion because a US 8 in men’s is not the same as a US 8 in women’s. Always check which column the size belongs to.
Shopping Online: Practical Advice for International Buyers
Buying shoes online from another country can be exciting. You get access to more brands, styles, and prices. But it also comes with challenges, especially when it comes to shoe size conversion. A small mistake can lead to uncomfortable shoes or costly returns. Here are some practical tips to shop smarter.
Always Check the Store’s Size Guide: Don’t rely only on general charts. Many brands publish their own conversion tables.
Read Customer Reviews: Reviews often reveal how a shoe really fits. Some buyers will mention if the shoe runs large, small, or true to size. This is especially useful when comparing UK to US shoe size or US to EU shoe size, since differences are common across regions.
Measure and Compare: Your foot length in centimeters is the most accurate guide. Write it down and use it when browsing charts. A 25 cm foot length usually equals China 40, US men’s 7, US women’s 8.5, or EU 40. Matching by centimeters reduces mistakes.
Understand Return and Exchange Policies: Before placing an order, check if the store accepts international returns. Some retailers make buyers pay for shipping back, which can be expensive. Others offer free exchanges. Knowing this helps you decide if the risk is worth it.
Order from Trusted Platforms: Stick to well-known marketplaces or official brand stores. They usually provide reliable shoe size conversion charts and better customer support. Unknown sellers may list wrong sizes or use inconsistent charts.
Consider Regional Differences: Remember that shoes made for the Asian market may be narrower. In contrast, European shoes may feel wider. Adjust your choice accordingly, especially if you know your feet are wide or narrow.
Buy One Pair First: If you are unsure, don’t order multiple pairs at once. Test one pair first. Once you confirm the right fit, you can shop with more confidence.
Conclusion
Understanding shoe size conversion makes international shopping simple and stress-free. By knowing how China, US, UK, and EU sizes relate, measuring your feet accurately, and checking brand-specific charts, you can find the perfect fit every time.
Don’t rely on guesswork. Use charts, read reviews, and consider foot width and style. With these steps, ordering shoes across borders becomes easier, safer, and more confident. Your next pair will fit just right—no surprises.
