Shoe Size Converter

About the Shoe Size Converter

The free Shoe Size Converter translates shoe sizes between US, UK, European (EU), and Japanese (JP) sizing systems for both men and women. Select your gender, choose your known size system, enter your size, and review the equivalent sizes.

Shoe sizing varies significantly across countries. US and UK sizes use different starting points and gender offsets. European sizes follow the Paris point system (each size = 6.67 mm). Japanese sizes are measured in centimeters of foot length. Shopping internationally or online can be frustrating without accurate conversions.

Our converter accounts for gender-specific offsets: women's US sizes are typically 1.5 sizes higher than men's for the same foot length. UK men's sizes are roughly 0.5 less than US men's, while UK women's sizes are roughly 2 less than US women's. The converter also shows foot length in centimeters.

When This Page Helps

International shoe shopping requires accurate size conversions. This converter handles gender offsets across all four major systems and reduces guesswork when ordering from overseas retailers.

How to Use the Inputs

1. Select your gender (men or women).
2. Choose the sizing system you know (US, UK, EU, or JP).
3. Enter your shoe size.
4. View the equivalent sizes in all other systems.
5. Check the foot length in cm for the most accurate fit.

Example Calculation

Tips & Best Practices

• Always measure your foot in the afternoon when feet are slightly swollen for the most accurate size.
• Sizes vary between brands — use foot length in cm as the most reliable universal measurement.
• Half sizes exist in US and UK but not in many EU systems; round up if between sizes.
• JP sizing is the simplest — it's just your foot length in centimeters.
• Width varies independently of length; some brands offer narrow (B) and wide (D/E) options.
• Children's sizes follow different scales and are not covered by adult conversion charts.

The History of Shoe Sizing

Modern shoe sizing originated in the 14th century with the barleycorn system in England. One barleycorn (1/3 inch) equals one size increment. The US adopted a modified version in the 1880s with a different starting point. Europe developed the Paris point system where one size = 2/3 cm.

Why Foot Length Matters Most

Since sizing systems are approximations and brands interpret them differently, measuring your foot length in centimeters is the most reliable way to find your size in any system. Stand on paper, mark heel and longest toe, and measure the distance.

Width Considerations

Shoe width is just as important as length for comfort. Standard widths are B (narrow), D (standard for men), and E/EE (wide). Some systems don't account for width, so check brand-specific width guides when ordering internationally.

Frequently Asked Questions

• What is a US men's 10 in EU sizes?

  A US men's 10 is approximately EU 43. The exact EU size can vary by manufacturer, so checking foot length in cm (about 28 cm for US 10) gives the best fit.

• How do women's sizes differ from men's?

  Women's US sizes are typically 1.5 sizes higher than men's for the same foot length. So a women's US 8.5 is equivalent to a men's US 7. UK and EU have their own gender offsets.

• What does JP shoe size mean?

  Japanese shoe sizing (JP or JPN) is based on foot length in centimeters. If your foot measures 26 cm, your JP size is 26. It's the most straightforward sizing system.

• Why do shoe sizes vary between brands?

  There is no universal standard enforced for shoe sizing. Each brand uses its own lasts (foot models) and may interpret sizing charts differently. Foot length in cm is the most reliable cross-brand measurement.

• How accurate are shoe size converters?

  Shoe size converters provide approximate equivalents based on standard charts. Actual fit depends on the brand, shoe style, foot width, and arch shape. Use the converter as a starting point and consult brand-specific charts when available.

• Is UK sizing the same as US sizing?

  No. For men, UK sizes are about 0.5 less than US sizes (US 10 = UK 9.5). For women, UK sizes are about 2 less than US sizes (US 8 = UK 6). The scales are different.
