Free Shoe Size Chart - US, EU, UK Shoe Size Conversion

A Most people have slightly different-sized feet — up to 5mm difference is normal. Always fit shoes to your larger foot. Use an insole in the smaller shoe if needed.

A Allow 5-10mm of growing room, but not more — oversized shoes affect walking and foot development. Check sizing every 3-4 months for growing children.

A While not strictly 'every single purchase,' it's highly recommended, especially when buying from new international brands or regions. Sizing standards can vary significantly, even within the same country, and foot size can change over time due to swelling, age, or activity. Using our chart with your current foot length ensures the most accurate conversion and best fit, minimizing returns.

A If your foot length falls between two sizes on our international shoe size chart, it's generally recommended to round up to the next half or full size. This provides necessary wiggle room, preventing discomfort and potential foot issues. Consider the shoe type—athletic shoes often require more toe space. Also account for socks and natural foot swelling throughout the day for the best fit.

A Measuring a wriggly child's foot for our international shoe size chart can be tricky. Try doing it while they're asleep, or engage them by tracing their foot on paper while they stand on it. Ensure their heel is against a wall for accuracy. Use the longest point from heel to toe to get the precise foot length in millimeters for conversion.

A For the most accurate shoe size conversion, measure your foot length in millimeters at the end of the day or after significant activity. Feet naturally swell throughout the day, often becoming slightly larger. This ensures you're accommodating your foot at its maximum size, preventing discomfort and ensuring a comfortable fit even after prolonged wear. Our international shoe size chart will then provide the best match.

A Our free international shoe size chart uses foot length in millimeters for accurate conversions. While it doesn't directly convert width, this is crucial for comfort. If you have narrow or wide feet, measure your foot length and then consult the chart. If you're between sizes, wide feet should generally round up, while narrow feet might find their standard length adequate. Always check the specific brand's width options or reviews for an optimal fit that combines precise length and appropriate width.

A Shoe sizing isn't standardized globally. Different manufacturers use varying measurement systems and last shapes, which are the foot molds shoemakers use. This means a US 9 in one brand might feel like a US 9.5 or even a US 8.5 in another. Our tool converts your foot length in millimeters to standard US, UK, and EU sizes, giving you a baseline. Always double-check with individual brand charts if possible.

A Yes, but with one big caveat. High heels change your foot's position, making length slightly less critical than width and arch support. Start with your foot length in millimeters on our chart to find your base size. Then drop down half a size for pointed toes or narrow heels. For stilettos over 4 inches, consider going up half a size to prevent toe jamming. Your heel will slide less with proper fit.

A Not entirely. Foot length in millimeters gives you a solid starting point, but width, arch height, and toe shape matter too. Our chart converts length to US, EU, and UK sizes accurately. But a size 10 in a narrow sneaker won't fit the same as a size 10 in a wide boot. Always pair the chart with product reviews mentioning fit. For best results, measure both feet and check return policies before buying.
