This post is all about Complete Shoe Size Conversion Chart, the most common US to UK, EU, and other International Sizes.
Shopping for shoes from international brands can feel confusing when size numbers don’t match what you’re used to.
A US size 8 doesn’t equal a UK size 8, and European sizing uses a completely different numbering system.
This comprehensive shoe size conversion guide helps you translate between US, UK, European, and other international sizing systems so you can shop confidently from any country.
Whether you’re buying from a British retailer, browsing European fashion sites, Understanding size conversions prevents costly ordering mistakes and frustrating returns. I also have such experiences!

Why Shoe Sizes Differ Between Countries
Different countries developed their shoe sizing systems independently, leading to the confusing variety we see today.
The United States uses one measurement system, the United Kingdom uses another, and Europe uses yet another based on centimeters.
US sizing is based on the length of the shoe last (the mold used to make shoes) measured in barleycorns—an old unit equal to 1/3 inch.
UK sizing follows a similar barleycorn system but starts at a different point. European sizing uses the Paris point system, where each size equals 2/3 of a centimeter.
Asian countries like Japan and China have their own systems, often based on foot length in centimeters.
This explains why a shoe that fits perfectly in one country’s size might not match a different country’s equivalent.
Understanding these differences helps you order the right size every time, no matter where you’re shopping.

Japanese and Chinese Shoe Sizes
Asian sizing typically uses actual foot length in centimeters, making it more straightforward once you know your foot measurement.
Japanese sizes directly correspond to foot length in centimeters. For example, size 25 means 25cm foot length.
Chinese sizes also use centimeters but sometimes vary slightly by manufacturer. Always check the specific brand’s size chart.
Quick conversion: Measure your foot in centimeters and use that number as your Asian shoe size, but verify with the retailer’s specific chart.
How to Use This Conversion Chart
Follow these steps for accurate size conversion
Step 1: Measure your feet following the guide in our foot measuring article. Write down your foot length in both inches and centimeters.
Step 2: Find your usual US shoe size in the conversion chart above.
Step 3: Look across the row to see the equivalent UK, EU, or other international size.
Step 4: Cross-reference with your actual foot length measurement to confirm the size is correct for your feet.
Step 5: Check the specific brand’s sizing chart, as some brands run large or small compared to standard sizing.
Important Conversion Tips from an Expert!
Half sizes matter: European sizing doesn’t always have exact half-size equivalents. When converting, you may need to round up for comfort.
Width isn’t universal: These charts show length only. Shoe width (narrow, medium, wide) varies by brand and isn’t standardized internationally.
Athletic shoes often differ: Running shoes and athletic footwear sometimes use different sizing than dress shoes, even within the same country.
Always check brand charts: Use this guide as a starting point, but check each brand’s specific size chart since manufacturers vary.
When in doubt, size up: If you’re between sizes after conversion, going up a half size usually provides better comfort than sizing down.
Brand-Specific Sizing Notes
Different brands fit differently even when using the same size numbers. Here are general guidelines:
Nike: Tends to run small; many people size up a half size
Adidas: Usually true to size but varies by style
New Balance: Known for running true to size with good width options
European brands (Clarks, Ecco): Often run large; consider sizing down
Asian brands: Typically run smaller; size up one full size from US sizing
Always read customer reviews that says “true to size,” “runs small,” or “runs large” when shopping online.
Converting Athletic vs Dress Shoe Sizes
Your athletic shoe size might differ from your dress shoe size even within the same country. Athletic shoes are designed with more room for foot movement during activity, while dress shoes fit more snugly.
If you wear a US 9 in running shoes, you might wear a US 8.5 in dress shoes. When converting international sizes, account for this style difference.
What If Sizes Don’t Match Exactly?
Sometimes your foot measurements fall between standard sizes. Here’s what to do:
Round up for comfort: Shoes slightly too big can be adjusted with insoles; shoes too small cause pain.
Consider width: If length is correct but shoes feel tight, you may need a wider width rather than a larger size.
Check return policies: When shopping internationally, ensure you can return or exchange if the conversion doesn’t work perfectly.
Read reviews: Other customers often mention whether to size up or down for specific shoes.
Shopping International Brands with Confidence
Now that you understand size conversions, you can confidently shop from any country. I Request you to make a note of these things.
Measure your feet first using our measurement guide for the most accurate starting point. Use your actual foot length in centimeters when shopping Asian brands.
Check each brand’s specific size chart rather than relying only on general conversions.
When in doubt, contact customer service—most international retailers help with sizing questions. Save this conversion chart for future reference when exploring global shoe shopping.
Thanks and have a great day.
