How to Measure Your Shoes Size
Stand on a piece of paper with your heel against a wall. Mark the tip of your longest toe, then measure the distance from the wall to the mark in centimetres. Measure both feet — most people have one foot slightly larger — and use the longer measurement. Measure at the end of the day when feet are at their largest. This length maps directly to JP sizes and can be converted to any other system with our chart.
Understanding UK and US Sizing
UK sizes use the British sizing system, which is closely related to US sizing but offset by roughly half a size for footwear and one or two sizes for clothing. UK sizing is used throughout the United Kingdom, Ireland, and many Commonwealth countries. Historically rooted in the barleycorn system (each size = 8.47 mm), UK shoe sizes still follow that progression today.
The US sizing system is the standard in the United States and is used by most American brands. US sizes are typically numbered and can differ significantly from European or Asian systems. Most US retailers display sizes prominently on labels and online, but the underlying measurements (in inches or centimetres) vary between brands, so treating US sizes as approximate is safest.
Tips for Converting Men's Shoes Sizes
US and UK men's shoe sizes are offset by roughly 0.5 — a US 10 is typically a UK 9.5. Women's sizes differ by about 2 full sizes between the two systems.
When ordering from UK-based retailers like ASOS or Clarks, make sure the site is displaying UK sizes, not US. Many international sites let you toggle between systems.
Sizes vary between brands — a US 10 in Nike may fit differently than a US 10 in Adidas. Always check the brand's own chart when buying online.
If you are between sizes, size up for athletic shoes (you need room for swelling during exercise) and consider sizing down for formal shoes (leather stretches over time).
Width matters as much as length. Some brands offer wide (W) and narrow (N) options. If standard-width shoes feel tight across the ball of your foot, try a wide version rather than going up a full size.
