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.
US women's shoe sizes run the same barleycorn scale as men's but with a different zero offset — US women's are typically 1.5 sizes larger than the equivalent men's size. US women's size 8 = US men's 6.5 = EU 39 = UK 6.
Women's shoes in the US range from size 4 to 12, with size 7–8 being most common. Wide widths are labeled W or WW; narrow are N. Half sizes are common and meaningful — a half size represents 1/6 inch (~4.2 mm) of foot length.
Interesting fact: The 1.5-size offset between US men's and women's comes from historical manufacturing — men's and women's lasts (foot molds) used different reference feet. A women's size 8.5 and a men's size 7 use the same last, just with different labelling.
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.
