In this article, we’ll walk you through the distinctions in sizes for clothing and shoes between the UK and the US, and how this applies to men, women, and children. We hope this information will take the stress out of your shopping, so you can concentrate on what matters – the clothes!

Women’s Clothing Size Conversions: UK to US Size Chart

Women’s clothing sizes aren’t as straightforward as men’s, but still not super complicated. The good news is, there’s a nifty little trick when it comes to translating UK sizes to US sizes for women’s clothing. Generally, US sizes tend to be around two sizes smaller than their UK counterparts. So, if you want to make the switch, just subtract four from your UK size, and voilà, you’ve got your perfect US size all figured out.

To give you an example, if you’re a size 6 in the UK you would be a size 2 in the US. This rule also applies to jeans, so you can simply subtract four from your UK size to find yourself a nice-fitting pair of trousers too.

It’s worth noting that women’s clothing sizes don’t have a universal standard and can change from manufacturer to manufacturer. So particularly if you’re shopping online, it’s best to check if they have their own conversion chart and use that to find your perfect size.

Women’s Shoe Size Conversions: UK to US Size Chart

Women’s shoe sizes also don’t translate exactly, but they’re not too far off either. To find your US equivalent in shoe size, you can simply add two to your regular UK shoe size. So if you’re a 3 in the UK, you’d be a 5 in the US – the same applies to half sizes as well.

Finding clothes to fit your child can be a challenge as it is, making sure they’re not going to grow out of it too soon. Converting your children’s clothing sizes can add an extra layer on top of this, but we have compiled a conversion chart to help you navigate UK to US sizes.
