How to Use This Shoe Size Converter
- Select your category: Men, Women, or Kids
- Choose the size system you know (US, UK, EU, or foot length in cm)
- Enter your size in the selected system
- Click 'Convert' to see your size in all other systems
- Note that conversions are approximations - sizing varies between brands
Example: A US Men's 10 converts to UK 9, EU 43-44, and approximately 28 cm foot length. When shopping European brands, look for size 43 or 44.
Tip: Measure your feet in the afternoon when they're slightly swollen. Stand while measuring, and measure both feet - use the larger measurement.
Why Use a Shoe Size Converter?
International shoe shopping requires understanding different sizing systems. A US 10 means nothing to a European retailer, and getting it wrong means costly returns.
- Buy shoes from international online retailers
- Shop while traveling in countries with different sizing
- Convert between men's and women's sizes for unisex styles
- Find children's shoes when only adult-system sizes are known
- Verify sizing when brands use different regional standards
- Match foot measurements to appropriate shoe sizes
Understanding Your Results
Conversions are based on standard foot length but vary between manufacturers.
| Result | Meaning | Action |
|---|---|---|
| Half-size difference | Normal variation between systems | Both sizes might fit - try if possible |
| Full-size difference | Systems don't align precisely | When in doubt, size up for comfort |
| Multiple options shown | Size falls between standard sizes | Check brand-specific charts; athletic brands often run small |
| Foot length in cm | Most universal measurement | Measure yourself and use this for most accurate conversion |

About Shoe Size Converter
Formula
EU = (Foot Length cm + 2) × 1.5 (approximately) The Paris point formula adds ~2 cm for toe room, then divides by 0.667 cm per size. Actual conversions vary, which is why using foot length in cm is most reliable.
Current Standards: ISO 9407 defines the Mondopoint system (foot length × width in mm) used in military and athletic footwear. Most consumer shoes use regional systems without formal standardization.
Frequently Asked Questions
Why don't my shoes match the converted size exactly?
Shoe sizing isn't standardized between brands. Nike often runs small, while New Balance tends to run true or large. Dress shoes typically fit differently than athletic shoes. Always check brand-specific size charts and reviews mentioning fit when buying online.
How do I measure my foot length correctly?
Stand on paper against a wall (heel touching wall). Mark the tip of your longest toe. Measure from the wall to the mark in cm. Do both feet - they're often different sizes. Measure in the afternoon when feet are largest. Add 0.5-1 cm for breathing room.
What's the difference between US men's and women's sizes?
US women's sizes are about 1.5 sizes larger numerically for the same foot length. A woman with a foot length requiring US Men's 8 would wear US Women's 9.5. UK sizes are more consistent between genders, and EU sizes are unisex.
Should I size up or down when between sizes?
Generally size up. Your feet swell during the day and during activity. Shoes that are too small cause blisters, bunions, and toe problems. You can always add insoles to a slightly large shoe, but you can't stretch a shoe that's too small.
Do shoe widths convert between systems?
Width isn't standardized across systems. US uses letters: B (narrow), D (standard men's), EE-EEEE (wide). UK uses similar letters. EU sizes assume standard width - look for 'wide fit' options. If you need wide shoes, check if the brand offers width options before converting.
