CM (centimeters) shoe sizing directly measures foot length and is used in Japan and is the clearest international reference. It removes ambiguity from gender-specific or regional numbering by using actual physical measurement.
Japanese shoe labelling uses foot length in cm (e.g., 25 cm, 25.5 cm). This makes fitting straightforward: measure your foot length and add 0.5–1 cm for fit. CM sizing is also the most reliable cross-gender shoe size reference.
Interesting fact: Measuring foot length at the end of the day (when feet are at their largest due to swelling from walking) gives the best fit. Feet can differ in length by up to a full size — always fit to the larger foot.
UK shoe sizes use a numbering system where size 0 corresponds to a child's foot of 4 inches (101.6 mm), with each size increment being ⅓ inch (8.47 mm). Adult UK sizes start around 3. The system predates metrication and remains the standard in Britain.
UK adult sizes run roughly 1–14 for men and 2–10 for women. UK sizes are approximately 0.5 lower than US men's sizes (UK 9 = US 9.5) and about 2 lower than women's US sizes (UK 6 = US 8). UK children's sizes continue into adults without a break.
Interesting fact: The Mondopoint international shoe sizing standard (ISO 9407) attempted to replace all regional systems with foot length in millimeters, but despite adoption by NATO for military footwear, it has not displaced local systems in retail.
Shoe sizes are not standardized internationally. EU sizes use Paris points (⅔ cm), US sizes use barleycorns (⅓ inch), and UK uses a similar scale with a different offset. US men's and women's sizes differ by 1.5 sizes for the same foot. EU sizing is gender-neutral. The most reliable approach: measure foot length in cm and consult brand-specific size charts.
Always treat size conversions as a starting point — sizes vary significantly between brands and shoe styles.
