Japanese Shoe Size Conversion Guide
Convert Japanese shoe sizes to US, UK, EU and centimeters with foot-length measuring tips for sneakers, dress shoes and international shopping.
Japanese shoe sizing is popular in sneaker, streetwear and international fashion listings because it often uses centimeters directly. That makes it clearer than some regional labels, but you still need to compare the value with US, UK and EU systems using the Shoe Size Converter.
Measure Foot Length in Centimeters
Stand on paper, mark the heel and longest toe, then measure the distance in centimeters. Use the larger foot if your feet differ. This measurement is the best reference for JP sizing because the JP label is tied closely to foot length.
Choose Men's or Women's Conversion
A JP centimeter value can map to different US numbers depending on whether the shoe is labeled men's or women's. US scales have separate baselines, while JP and CM values are more neutral. Always compare the product category before choosing a US equivalent.
Check Width and Brand Shape
Two shoes with the same JP size may still feel different if one has a narrow toe box or low-volume upper. Sneakers, boots and dress shoes are built on different lasts, so read brand fit notes and reviews after converting the length.
