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 US and JP Sizing

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.

Japanese (JP) sizes are based on centimetre measurements. For footwear, the JP size equals the foot length in centimetres, making it one of the most intuitive sizing systems in the world. For clothing, JP sizes tend to run smaller than Western equivalents because they are cut to Japanese body proportions. Always measure in centimetres when shopping with JP sizing.

Tips for Converting Men's Shoes Sizes

JP shoe sizes are simply your foot length in centimetres — a JP 27 means a 27 cm foot. This makes Japanese sizing the easiest to verify with a ruler.

Japanese shoes sometimes run narrow compared to US shoes. If you have wider feet, consider going up 0.5 cm (half a JP size) when shopping Japanese brands like ASICS or Onitsuka Tiger.

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.
