Shoe Size Converter
Conversion Result
Most brands have slight variations in sizing. If between sizes, size up for a roomier fit or down for a snug fit.
💡 Tip: Sizes may vary slightly by brand, always check retailer size charts when possible.
How to Use This Tool
Follow these simple steps to convert your shoe size instantly:

- Select your target region and gender for the converted size.

Formula and Logic
This converter uses standardized international shoe size conversion charts for men, women, and kids. The logic works in two steps:
- First, your current size is converted to its equivalent foot length in centimeters (CM), which is the universal standard for shoe sizing.
- Second, the CM foot length is converted to the target region and gender's corresponding shoe size using verified conversion tables.
No complex math is required, as the tool references fixed industry-standard mappings for accuracy. Conversions account for regional differences between US, UK, and EU sizing, as well as gender-specific size variations.
Practical Notes
Keep these lifestyle-specific tips in mind when using your converted size:
- Online retailers may have brand-specific sizing variations, so always check the retailer's size chart before purchasing.
- CM sizing is the most accurate option for international shopping, as it measures actual foot length rather than regional size labels.
- Kids' shoe sizes change quickly, so measure their foot length in CM every 2-3 months for the best fit.
- For athletic shoes, consider sizing up half a size to accommodate thicker socks or foot swelling during activity.
- Vintage or secondhand footwear may follow older sizing standards, so conversions may be less accurate for older items.
Why This Tool Is Useful
Shoe size conversions are essential for everyday lifestyle needs, whether you're shopping online, traveling abroad, or buying gifts for friends in other regions.
This tool eliminates guesswork when purchasing footwear from international brands, reduces the risk of ordering the wrong size, and saves time comparing multiple size charts. It's perfect for frequent travelers, online shoppers, and parents buying kids' shoes across regions.
Frequently Asked Questions
Why does my converted size not match a specific brand's chart?
This tool uses industry-standard average conversions. Individual brands may adjust sizing for style, material, or fit, so always verify with the retailer's official size guide when possible.
Can I convert kids' sizes to adult sizes?
Yes, but note that kids' sizes stop at EU 38 (approx CM 25), which aligns with adult women's US 10 / EU 40.5. For larger adult sizes, use the men's or women's conversion options directly.
Is CM sizing the same for all genders?
Yes, CM measures actual foot length, so it is unisex. A 25 CM foot length will convert to the corresponding men's, women's, or kids' size based on regional standards.
Additional Guidance
For the most accurate conversion, measure your foot length in CM at home: stand on a piece of paper, mark the heel and longest toe, then measure the distance between the marks.
If you are between two sizes in your target region, refer to the brand's fit notes—some recommend sizing up for wide feet, others for narrow feet.
Keep a note of your CM foot length in your phone for quick reference when shopping across regions or brands.
