Quick answer
A men's US 9 is EU 42.5, UK 8, China 44, Japan 27 and Korea 270 – for a foot about 27 cm long.
Sneakers from the US, boots from the UK, running shoes from Japan – every country numbers men's shoes differently. Find your usual size in your own system and read across the row. The foot length in the last column is the safest way to compare between brands.
UK sizes are usually half a size to one size smaller than US sizes for men, and EU sizes rise in steps of about two thirds of a centimeter.

Typical equivalents. Brands differ, so check the brand's own chart when it has one. Chinese sizes (shops in China, online stores shipping from China) run about one size smaller than EU: compare your foot length in cm with the seller's chart.
How to measure your foot
- Stand on a sheet of paper with your heel against a wall, wearing the socks you will use.
- Mark the tip of your longest toe and measure from the wall to the mark in centimeters.
- Measure both feet late in the day and use the longer one.
- Find that length in the last column; between two sizes, take the larger one.
