How do I convert US shoe sizes to UK sizes?

US sizes are typically one size larger than UK sizes. For example, US Men's 9 equals UK 8.5, and US Women's 8 equals UK 6. However, the exact conversion depends on the manufacturer. Use our converter for precise conversions across all systems including foot length in centimeters.

What's the difference between US Men's and US Women's shoe sizes?

US Women's shoe sizes are approximately 1.5 sizes larger than US Men's sizes for the same foot length. For example, a US Men's 9 is equivalent to a US Women's 10.5. This difference exists because women's shoes historically used a different sizing scale. Always check the gender-specific size when shopping.

How accurate are shoe size conversions?

Our converter uses standard international sizing charts and is accurate for most brands. However, shoe sizing can vary between manufacturers, styles, and even different shoe types (athletic vs. dress shoes). We recommend using the foot length in centimeters for the most accurate sizing, and always checking brand-specific size guides when available.

Should I size up or down if I'm between sizes?

If you're between sizes, it's generally recommended to size up, especially for athletic shoes or if you have wide feet. Shoes that are slightly too large can be adjusted with insoles or thicker socks, but shoes that are too small can cause discomfort and foot problems. Consider the shoe type and your foot width when deciding.

How do I measure my foot in centimeters for the most accurate size?

Stand on a piece of paper and trace your foot outline. Measure from the heel to the longest toe in centimeters. Do this for both feet in the afternoon when feet are slightly swollen. Use the larger measurement and add 0.5-1cm for comfort. Enter this measurement in our converter's CM system for the most accurate size conversion.

Why do European (EU) shoe sizes use different numbers?

European sizes are based on the Paris Point system, where each size represents 2/3 of a centimeter (6.67mm). EU sizes are unisex and directly related to foot length, making them more consistent across brands. For example, EU 42 corresponds to approximately 26.7cm foot length. This system is used throughout Europe and is increasingly adopted globally.
