US and UK shoe sizes are two labels for the same foot lengths. The chart ties each US size to its UK equivalent through the foot length in centimetres, which is the one dimension that does not change between systems. If you know your foot length, you can confirm both sizes directly.
Remember that US sizing splits into separate men's and women's numbers while UK and EU use a single scale for both. When in doubt, convert by centimetres and size up if you fall between two rows. To measure your feet, see how to measure shoe size.
Common questions
How do I convert US shoe size to UK?
Find your US size in the chart and read across to the UK column, or use the converter above. Every size lines up with a foot length in centimetres, so the conversion is precise.
Does US to UK differ for men and women?
The US split is shown for both men and women in the chart. UK and EU use one number for both, while US uses separate men's and women's scales.
What if I am between two sizes?
Size up. A slightly long shoe is more comfortable than one that is too short, and you can adjust the fit with insoles or thicker socks.
