Shoe Size Converter

Convert shoe sizes between US, EU, UK, and CM for men, women, and children. Find your perfect fit across international sizing systems.

How it works

US men = (foot length in inches × 3) − 22 approximately. EU ≈ (foot length cm + 1.5) × 1.5. UK = US men − 0.5. US women ≈ US men + 1.5.

Worked example

A 26.5 cm (10.4 in) foot is roughly a US men's 8.5, UK 8, EU 42 and US women's 10.

Frequently asked questions

How do I measure my foot properly?

Stand on paper against a wall in the evening, mark the longest toe, and measure heel to mark. Feet swell during the day, so evening measurements avoid tight fits.

Why don't sizes match between brands?

Each brand uses its own last shape, and athletic, dress and boot lasts differ even within one brand. Treat conversion charts as a starting point and check the brand's own guide.

Should I size up for running shoes?

Usually half a size. Feet swell and slide forward on long runs, so aim for a thumb's width of space at the toe.
