If you're still wondering what’s the difference between UK and US foot size?—here’s a breakdown to make it crystal clear. Go through it to understand what makes them different.
Example: If you wear a UK 6, you’re a US 7 in men’s sizing and a US 8 in women’s. Does that help make the conversion easier for you to remember off the top of your head.
US and UK sizes use slightly different starting points when it comes to measurement. That’s why the size labels don’t match even though the shoes may look the same on the outside. Don’t get confused by that and keep referring to the size chart above for help.
Kids' sizes follow a similar pattern—the US size is one number ahead of the UK equivalent. This matters a lot when you're shopping online for shoes for boys or shoes for girls, especially when trying to size up for growing feet. You don’t want to get the wrong size and make the tiny tots uncomfortable.
The American vs British shoe sizes rule isn't 100% consistent across all brands. For instance, some American brands have slightly roomier fits, and certain fashion-forward brands may cut narrower. That's why it's always a good idea to try them on or check the brand-specific size guide when possible. Always check for return policies before ordering online from brands where you’re not confident about the size.
Measure your foot from heel to toe in centimeters or inches. This is the most accurate way to convert between UK vs US shoe sizes, because many international sizing charts are based on foot length. Use this to check against the illustrations in the size chart online.
Bookmark this page or screenshot the UK vs US size guide. It’s especially helpful when you're online shopping and can't try the shoes on. It can make the difference between a good shopping experience and a hassle.
A US men's size 8 is not the same as a US women’s 8. Women’s shoes are typically about 1.5 sizes bigger than men’s for the same foot length. So a men’s US 8 would be a women’s US 9.5.
When you’re exploring men shoes or women shoes, keep this in mind if the website doesn’t clearly separate the categories. There are some websites selling unisex designs so do remember to apply this logic there as relevant.
It’s safer to go half a size up if you’re unsure—especially if you plan to wear thicker socks or need extra room. Tight shoes are a no-go and can cause blisters and discomfort fast.
Some brands don’t offer half sizes. If your foot falls between two whole sizes, go up and use an insole if needed. This is a great trick when shopping online where returns can be a hassle.

The sizing systems were developed separately and use different base measurements. The US system typically starts from size 0 as an infant size, while the UK system has different origins altogether. So even though both regions use similar numbers, the actual size they represent differs.
Yes, just subtract 1 size (men) or 2 sizes (women) from your US size to get your UK equivalent—or refer to our size chart above. For kids, subtract 1 size from the US number to get the UK size.
No, most size conversions focus only on length. If you need wide or narrow shoes, be sure to check that separately as widths (like D, E, EE, etc.) may not align perfectly across countries.
