Shoe Size Converter — US to EU & UK Sizes + cm Chart

How to use Shoe Size Converter

Choose the category — Men or Women — in the first dropdown, since the scales differ.
Select your known US size in the second dropdown.
Read the four cards that appear: your size in US, UK and EU, plus the matching foot length in centimeters.
Cross-check the cm value against the brand's own size chart when buying online — centimeters are the most reliable common ground.

What is Shoe Size Converter?

A shoe size converter maps a size in one regional system to its equivalents in the others — US, UK and EU — plus the actual foot length in centimeters. The systems genuinely differ: UK sizes start counting from a different zero than US sizes (a US men's 10 is a UK 9.5), EU sizes run on their own scale based on Paris points (2/3 cm per size), and men's and women's scales are offset from each other within the US system.

The one honest measurement underneath it all is foot length in centimeters — which is why this tool shows it alongside each size. Brands vary, but centimeters give you the ground truth to compare against a brand's own chart.

About the Shoe Size Converter

This converter covers men's and women's shoe sizes across the US, UK and EU systems, with the matching foot length in centimeters — pick your known size and all equivalents appear at once.

It is built for online shopping: a men's US 9 is UK 8.5 / EU 42.5 / 27 cm; a women's US 8 maps to UK 6 / EU 39. Ordering from a European store with a US size in mind (or vice versa) is the classic way to get shoes a full size off, since guessing “EU is US plus 33” fails across the range — the scales are not parallel.

Tip: measure your foot in the evening (feet swell during the day), add about 1 cm of toe room, and compare that cm figure against the chart — it is more reliable than converting a size you half-remember.

Frequently Asked Questions

US men's 10 is UK 9.5 and EU 44, with a foot length of about 28 cm. The UK size is almost always half a size below the US men's size.

A women's US 7 is roughly EU 38 (UK 5), US 8 → EU 39, US 9 → EU 40. Women's UK sizes sit about 2 below the US number.

EU sizing counts Paris points — each point is 2/3 cm of last length — starting from zero, while US/UK sizes use barleycorn steps (1/3 inch) from different origins. The systems simply never shared a scale.

Stand on paper, mark heel and longest toe, and measure the distance in cm. Do it in the evening, measure both feet, use the larger, and allow ~1 cm of room beyond your foot length.

No — a Nike 42.5 and an Adidas 42.5 can differ by several millimeters, and widths vary too. Use this chart to get the right neighborhood, then check the brand's own cm-based chart.
