How Shoe Size Systems Work Around the World
Shoe sizing can be confusing because different countries use different systems with no universal standard. The United States uses separate scales for men and women, with women's sizes typically running 1.5 sizes higher than men's for the same foot length. The UK system is similar to US men's but offset by about half a size. European sizes use the Paris Point system, where each size increment equals two-thirds of a centimeter.
The CM (centimeter) or Mondopoint system, widely used in Japan and Korea, measures the actual foot length in centimeters and is considered the most straightforward system. For example, a foot that measures 28 cm is simply size 28 in this system. This converter uses standard industry conversion formulas based on foot length to translate between all major sizing systems.
Keep in mind that conversions are approximate because manufacturers may use slightly different lasts, width assumptions, and rounding conventions. Athletic shoes, dress shoes, and boots from the same brand can even differ. When buying shoes online or from international retailers, always consult the brand's specific size chart and consider ordering multiple sizes if returns are free. Measuring your foot in centimeters provides the most reliable starting point for finding the right fit.
