How it works

Pick who the shoes are for, then type a size in any system — US, UK, or EU. The other two sizes update instantly, along with the matching foot length in centimeters and inches. Brands vary a little, so use the foot length to double-check your fit.

Frequently asked questions

Why does the same foot have different sizes in each system? Each system starts counting from a different zero point and uses different step sizes. US and UK sizes are close but offset, while EU sizes follow a completely different scale based on the Paris point.

Are these conversions exact? They follow the standard published tables, but brands vary by up to half a size. The foot length in cm is the most reliable number — measure your foot in the evening and compare.

What if my size is between two rows? The converter shows the closest standard row. For running shoes most people prefer the larger size; for dress shoes, the smaller one often fits better.
