In the US kids' system, "C" means child sizes and "Y" means youth sizes. UK kids' sizes run up to 13.5 and then continue on the small adult numbers (1, 1.5, 2…), which is why the UK column restarts after 1Y.

How Shoe Size Systems Differ

The US and UK both build sizes on the length of the shoe last in thirds of an inch, but they start counting from different points — which is why UK men's sizes sit half a size below US, and UK women's about two sizes below. The EU (Paris point) system is based on centimeter-scale steps and is shared across Europe. Because brands cut their shoes a little differently, treat every chart — including this one — as a close guide, and check the specific brand's chart before ordering.

Frequently Asked Questions

What is a US men's size 9 in UK and EU sizes?

A US men's 9 is a UK 8.5 and an EU 42.5. US men's sizes run half a size above UK sizes across the whole chart.

Are US and UK shoe sizes the same?

No. For men, UK sizes are 0.5 lower than US sizes (US 10 = UK 9.5). For women the gap is bigger — about 2 sizes (US women's 8 = UK 6). Always check whose chart you are reading.

How do US kids' shoe sizes work?

US kids' sizes marked C are children's sizes (for example 10C–13.5C). After 13.5C the scale continues with Y (youth) sizes — 1Y, 2Y, 3Y — and then joins the adult men's and women's scales.

Do shoe size conversions vary by brand?

Yes, slightly. These charts are the standard industry conversions, but individual brands can run up to half a size large or small. When buying online, check the brand's own chart and, if you are between sizes, choose the larger one.
