What is a Shoe Size Converter?
It's a cross-reference tool that translates a shoe size from one country's system into all the others. Because US, UK, and EU sizing each use different starting points and increments — and men's and women's US sizes are offset by about 1.5 — a number that means one thing on a US box means something else entirely in Europe. This converter lines them all up from a documented chart.
Use it to shop across borders with confidence, decode an international brand's size guide, or work out your size from a plain foot-length measurement. The results are nominal fitting sizes — there's no single global standard, so always check the maker's own chart and, where you can, try the shoe on.
❓ Frequently Asked Questions
How does the shoe size converter work?
Enter a size in whichever system you know — US men's, US women's, UK, EU, or foot length in centimetres — and pick that system from the dropdown. The tool looks up the matching row in a documented cross-reference chart built from major-brand size guides and returns the equivalent size in every other system at once, so you can shop confidently from any country's sizing.
Why is US women's sizing higher than US men's for the same shoe?
US women's sizes run about 1.5 sizes larger than US men's for the same physical shoe length. So a US men's 9 is roughly a US women's 10.5. That offset is baked into the chart, which is why converting the same foot length gives you two different US numbers depending on whether it's labelled men's or women's.
Is EU or UK sizing more reliable than US sizing?
None is a true global standard. EU sizing is based on the Paris point (about 6.67 mm per size) and tends to be consistent across European brands, while UK and US sizes use different starting points and increments. Because there's no single authority, the safest approach is to know your foot length in centimetres and match it to the maker's own chart.
How do I measure my foot length in centimetres?
Stand on a sheet of paper with your heel against a wall, mark the tip of your longest toe, and measure from the wall to the mark. Do it late in the day when feet are largest, measure both feet and use the longer one, and add a small allowance for toe room. That centimetre figure is the most reliable input for this converter.
