Shoe size converter for men and women: convert US, UK, EU, cm, mm, Japan and Korea shoe sizes. Use this shoe size chart to compare adult sizes, switch between systems, and find the closest match when shopping across brands and countries.
Use this shoe size converter to compare adult shoe sizes across the most common systems, including EU, US, UK, centimeters, millimeters, Japan, and Korea. It is useful when a store shows sizes in a different system, when you want a quick shoe size chart before ordering online, or when you need to compare men’s and women’s sizing more clearly.
This tool gives you a fast size conversion, but exact fit can still vary by brand, model, width, and last shape. If you are between sizes or buying a brand for the first time, it is still a good idea to check the brand’s own size guide as well.

Shoe Size Converter FAQ
What is a shoe sin{BLOCK}e converter?
A shoe si{BLOCK}e converter compares shoe sizing systems such as EU, US, UK, centimeters, millimeters, Japan, and Korea. It helps you find the closest equivalent size when a store, brand, or country uses a different sizing standard.
How do I convert US shoe size to EU shoe size?
Choose the correct adult scale first, because US men's and US women's sizes are different. Then enter the size in the source system and switch the output to EU. The converter shows the closest matching value in the target system.
Why are men's and women's shoe sizes different in the US?
US men's and US women's shoes use different numbering scales, so the same foot length does not produce the same US size. EU and centimeter measurements are usually easier to compare directly across sexes.
Is shoe size in cm more accurate than EU or US sizes?
Centimeters and millimeters are usually the clearest reference because they map directly to foot or last length. EU, US, and UK sizes are convenient for shopping, but cm or mm often makes cross-brand comparisons easier.
How should I measure foot length before converting shoe size?
Measure while standing, from the back of the heel to the tip of the longest toe, and use the longer foot if they differ. For everyday shoes, many fitting guides suggest leaving about 1 to 1.5 cm (roughly 3/8 to 1/2 inch) of space in front of the longest toe, especially for athletic shoes.
Are Japan and Korea shoe sizes based on foot length?
In many charts, Japan and Korea sizing is shown close to a metric foot-length style, which is why these systems are helpful when you want a cleaner conversion reference. Retail implementations can still vary by brand.
Can a shoe size chart guarantee the perfect fit?
No. A shoe size chart gives you the closest standard conversion, but fit can still change by brand, model, width, last shape, and intended use. Treat conversion as the starting point, then check the seller's fit notes when possible.
