Based on common US brand size charts - exact fit varies by brand.

How this works

Shoe sizing isn't based on a single mathematical formula - each system (US, UK, EU) was developed independently, and brands calibrate slightly differently. This converter uses a commonly referenced US brand chart mapping US sizes to their approximate UK, EU, and centimeter equivalents.

Example

Men's US size 10 ≈ UK 9.5 ≈ EU 44 ≈ 27.9 cm foot length.

Step-by-step guide

  1. Choose men's or women's sizing.
  2. Select your US size and read the equivalent UK, EU, and centimeter measurements.

Common mistakes

Assuming all brands use identical sizing - actual fit varies enough between brands that checking a specific brand's own size chart is worthwhile before an important purchase.
Using a men's chart for a women's shoe or vice versa - the two use different base measurements, not just a simple size-number offset.

Frequently asked questions

Why do shoe sizes vary between brands?

There's no single global governing standard for shoe sizing, so brands calibrate their own lasts (the foot-shaped forms shoes are built on) somewhat differently, leading to small real-world variations even at the "same" labeled size.

How do I measure my foot length accurately?

Stand on a piece of paper, trace your foot, and measure from heel to the longest toe. Measure both feet, since they're often slightly different sizes, and use the larger measurement.

Is there a difference between men's and women's sizing systems?

Yes - for the same foot length, women's US sizing typically runs about 1.5-2 sizes higher than men's US sizing, which is why unisex conversions need care.
