UK to US Clothing Size

It’s no secret that clothing sizes vary drastically from country to country. Namely, UK clothing sizes are often quite different than US sizes, and unless you’re familiar with the conversion charts, it can be challenging to shop for clothes in a foreign country or online. 

In this article, we will take a look at how UK clothes sizes convert to US sizes and provide size comparison charts for women’s, men’s and children’s clothing and footwear. We hope this information will help make your next shopping trip abroad or online shopping spree a little bit easier!

Women’s Clothing: UK to US Size Conversion

When it comes to women’s clothing, it is easy to convert a UK size into a US size if you follow one simple rule. Women’s clothing sizes in the US are typically two sizes smaller than their UK counterparts. So, if you were to subtract four from your regular UK size, you would get its US equivalent.

For example, if you want to buy a UK size 10, you need to look for a US size six. The best way to ensure you’re buying the right size clothing when shopping in the UK is to know your exact measurements and find a clothes size converter that includes both UK and US clothing sizes.

Below is a size comparison chart between the UK and the US for women’s clothing.

To convert women’s jeans from the UK to US sizing, you need to follow the same rule. So, simply subtract four from your regular UK jeans size, and you will find your perfect fitting jeans.

Note that there is no international standard for women’s clothing sizes. They can vary from one manufacturer to the other, so if you are shopping online, it is best to see if your retailer has its own conversion chart. That way, you can avoid any unpleasant surprises when your order arrives.

Women’s Shoes: UK to US Size Conversion

Moving on to women’s shoe sizes, they can also vary significantly between the US and the UK. As a rule of thumb, shoe sizes in the UK are two sizes smaller than in the US. That would make a UK shoe size two a size four in the US. Half sizes are exactly the same, so if you are a shoe size 2.5 in the UK, you would be a 4.5 in the US. 

Simple, right? Take a look at the women’s footwear conversion chart below, and you will easily find your perfect shoe size in no time.

Kids Clothing Size: UK to US Conversion

Children grow up fast, so it is tricky enough to find the right clothes size for your little one as it is. But shopping abroad or online can open up a whole new world of confusion. That is why using a conversion chart such as the one below can help you discover the size you need.

But before looking at the chart, there are a couple of things you should know. Newborn clothes are labelled as NB in both countries, whereas toddler clothes are labelled by age. Clothes for a two-year-old would be labelled as 2-3 in the UK and 2T in the US.

So if you are looking for the US equivalent to your child’s UK size, simply look it up in the UK and US size chart below, and you’ll have your answer.

Age Range UK Children’s Clothing Size US Children’s Clothing Size
Up to 3 Months 0-3M 0-3M
3-6 Months 6M 3-6M
6-9 Months 9M 6-9M
9-12 Months 12M 9-12M
12-18 Months 12M 12-18M
18-24 Months 18-24M 18-24M
2 Years 2-3 2T
3-4 Years 3-4 3T-4T
4-5 Years 4-5 5
5-6 Years 5-6 6
6-7 Years 6-7 6X-7
7-8 Years 7-8 7-8

9-10 Years 9-10 10
10-11 Years 10-11 11
11-12 Years 11-12 14

These size conversions are based primarily on age, but you should also pay close attention to other factors, such as the child’s height and weight. When purchasing clothes for your child, be sure to look at the size chart of the specific retail or brand you are buying from. You should always choose the size corresponding to your child’s body measurements rather than their age.
