Shoe sizes in Japan
Japan uses sizes that are the foot length in centimetres (JIS S 5037), but brands print a smaller US size beside it: on 14 of 16 brands’ charts, Japan 26 is a men’s US 8, which by the standard fits a foot up to 25.4 cm; Clarks’s gives US 9 and Golden Goose’s gives US 6.
By the standard, Japan 26 fits a foot up to 26.0 cm: a men’s US 8.5–9, women’s US 10–10.5, UK 7.5–8, EU 40.5–41.

On brands’ own charts, 6 of 16 men’s and 1 of 16 women’s Japan sizes are paired with the standard’s US size. This is the US size most brands print beside each Japan size, so if you know the size on your shoes, start here; where it differs from the standard below, go by the brand’s chart.

The standard (JIS S 5037) makes each size for its own foot length and allows a foot up to half a step either side. Here, as in our calculator, a foot gets the first size at least as long as it, so a size fits feet longer than the size before it, up to its own length, so you never get a size shorter than your foot. Where that range spans more than one size elsewhere, all of them are shown.

- Girth/width is a separate letter: A, B, C, D, E, EE, EEE, EEEE, F, G.
Children’s shoes use the same scale. Kids’ sizes has every size with its foot length.
