How to Use the Shoe Size Converter
Select the sizing system you already know (US, UK, EU, or CM) and enter your shoe size. The converter instantly maps your size to all four systems using a standard reference table. This is especially useful when shopping online from international retailers that may only list sizes in one system.
The conversion is based on standard men's sizing charts. Keep in mind that women's US sizes are typically 1.5 to 2 sizes larger than men's for the same foot length. If you are converting women's sizes, subtract 1.5 from the women's US size before entering it, or measure your foot in centimeters for the most accurate cross-system conversion.
Understanding Shoe Sizing Systems
The US system uses a scale where each full size increment represents about one-third of an inch (8.47 mm). Half sizes bridge the gap. The UK system is similar but offset by about half a size from the US system. The EU (Continental European) system uses Paris Points, where each size is 6.67 mm apart. Centimeter sizing, common in Japan and parts of Asia, directly measures foot length. Because these systems use different increments and starting points, a conversion table is the most reliable way to translate between them.
Tips for Getting the Right Fit
Measure your feet in the afternoon or evening when they are at their largest. Stand while measuring and always measure both feet, as one foot is often slightly larger. Use the larger measurement for sizing. Leave about a thumb's width of space between your longest toe and the end of the shoe. Width also matters, and standard sizing does not account for wide or narrow feet. If you frequently find shoes too tight or too loose despite correct length, consider brands that offer width options.
International Shopping Tips
When ordering shoes from another country, always refer to the brand's own size chart if available, as sizing can vary between manufacturers. Pay attention to whether the listed size is men's, women's, or unisex. Keep in mind that return shipping for international orders can be costly, so getting the size right the first time saves both money and hassle. Measuring your foot in centimeters and matching against the brand's chart provides the most reliable fit.
Frequently Asked Questions
How do I convert US shoe size to EU?
US and EU shoe sizes follow different numbering systems. Generally, add about 33 to a men's US size to approximate the EU size (e.g., US 10 is roughly EU 43). However, the relationship is not perfectly linear, so using a conversion chart or our calculator gives the most accurate results.
What is the difference between US and UK shoe sizes?
US men's sizes are typically about 0.5 to 1 size larger than UK sizes. For example, a US 10 is approximately a UK 9.5. The difference is consistent across most of the size range, making conversion straightforward once you know the offset.
How do I measure my foot in centimeters for shoe sizing?
Place your foot on a piece of paper, mark the heel and the tip of your longest toe, then measure the distance in centimeters. This is your foot length. Compare it to a size chart: for example, 26.0 cm corresponds to approximately US 10, UK 9.5, or EU 43.
Do shoe sizes vary between brands?
Yes, shoe sizes can vary significantly between manufacturers. A US 10 in one brand may fit differently than a US 10 in another. This is because brands use different lasts (foot-shaped molds) and may interpret sizing standards differently. Always try shoes on when possible and check brand-specific size charts.
Are men's and women's shoe sizes the same?
No, men's and women's shoe sizes use different scales. In the US system, women's sizes are typically 1.5 to 2 sizes larger than men's for the same foot length. For example, a women's US 9 is approximately equal to a men's US 7.5. EU sizes and CM measurements are the same regardless of gender.
