About This Converter
Shoe sizing standards vary between countries and even between manufacturers. The US, UK, and EU each use different numbering systems, and sizes also differ between men's, women's, and children's shoes. This converter uses standard approximation formulas to give you quick reference conversions. For the most accurate fit, always try shoes on or consult the specific brand's size chart, as sizing can vary by up to half a size between manufacturers.
FAQ
Why do shoe sizes differ between countries?
Different countries developed their sizing systems independently. The US and UK systems are based on the length of the last (foot mold) measured in barleycorns (1/3 inch), while European sizes use the Paris point (2/3 cm). These different base units and starting points result in completely different numbering, even though they ultimately measure the same thing: foot length.
What is the difference between men's and women's shoe sizes?
In the US sizing system, women's sizes are typically 1.5 sizes higher than men's for the same foot length. For example, a men's US 8 is roughly the same as a women's US 9.5. In the UK system, the difference is about 0.5 sizes. EU sizes are the same for both men and women — an EU 42 is the same length regardless of gender.
How do I measure my foot to find the right size?
Stand on a piece of paper with your heel against a wall. Mark the tip of your longest toe. Measure the distance in centimeters from the wall to the mark. Do both feet and use the larger measurement. Add about 0.5-1 cm for comfort, then use this converter to find your size in any system. Measure your feet in the afternoon when they are slightly larger from daily activity.
Are kids' shoe sizes the same across all brands?
No. Children's shoe sizes can vary significantly between brands and even between shoe styles from the same brand. The sizing numbers follow a general standard, but the actual fit depends on the shoe's design, width, and the manufacturer's interpretation of the standard. Always refer to the brand's specific size chart and, when possible, measure the child's foot in centimeters for the most reliable comparison.
