So that you don’t get confused while converting your US shoe size to UK or vice-versa.
Before we start, let’s understand the US and UK shoe sizing patterns & how US shoe sizes compare to the UK.
Understanding the US Shoe Sizes
Shoe sizes are commonly measured using a barleycorn system in the United States. A number indicates the shoe’s length, while a decimal point (e.g., 7.5) indicates a half size. Men’s, women’s, and children’s sizes are all included in the US shoe sizing system, and each has a unique range.
Sizes for men often range from 6 to 18, or higher, depending on the brand and style. Conversely, women’s sizes often fall between 4 and 14.5. Children’s sizes are measured on a separate scale; for example, newborns start at size 0 and grow up to size 13.5.
Understanding the UK Shoe Sizes
Shoe sizes in the UK are determined by the foot’s length, measured in inches. The UK also uses the barleycorn system but the measurement starts from 0. Women’s sizes start at 2 and can go up to 9 or more, while men’s sizes often vary from 3 to 15.
Children’s sizes also follow a similar pattern: newborn sizes begin at 0 and continue up to around 13.5 for older kids. Half sizes are also part of the UK sizing system; they are indicated by appending “half” to the size (e.g., 7.5). In contrast to the US system, the UK uses the same numerical scale for both men’s and women’s sizes.
How do UK Shoe Sizes Compare to the US?
Countries that use US and UK sizing system uses barleycorn as their measurement unit. One barleycorn is equal to a third of an inch i.e. 1/3. However, both sizing systems are not identical because the US starts their size from 1. As a result, US sizes are one size larger than UK shoe sizes. For instance, US size 8 is UK size 7.
Another thing to keep in mind is that both sizing system gets more intricate. There is not much difference in UK0 and UK1, both of them are 12 inches in length.
Apart from the general sizes, we also have to understand different brands use their own touch with the sizing system. The shoe cuts may vary among various brands with different widths. Sometimes, you may also want to go one size up to accommodate the width of your feet.
How to Convert UK to US Shoe Size?
There is one little but important change involved in converting UK to US shoe sizes. To convert from the UK to the US market, or vice versa, add 0.5 or 1 size to your UK size for men’s shoes and 2 sizes for women’s shoes.
This applies to shoe purchases made in the UK and US. For instance, you would probably require a US size 8.5 or 9 if you wear a UK size 8 in men’s shoes. If you typically wear a UK size 6 in women’s shoes, you’ll probably need a US size 8.
Remember that these conversion rules are broad and that different companies may have different suggestions for sizes, so it’s always a good idea to verify the brand’s particular sizing requirements.
To simplify the conversion between UK and US shoe sizes, it’s important to understand that UK sizes are half a size (0.5) smaller for men and two sizes (2) smaller for women than US sizes.
Still, have doubts? check out the formula for shoe conversion:
- US men’s shoe size = UK men’s size + 0.5
- US women’s shoe size = UK women’s size + 2

6 Tips for Finding Perfect-Fitting Shoes

Although purchasing shoes online might be challenging, you can improve your chances of obtaining the ideal fit by following these suggestions:
Know Your Measurements: Take precise measurements of the length and breadth of your foot (follow these steps). Based on your dimensions, sizing tables are available from many online retailers to assist you in selecting the appropriate size.
1. Check Reviews
Consumer evaluations can provide important details regarding the comfort and fit of a specific shoe. Keep an eye out for remarks on size and determine whether or not others agree that a certain brand’s shoes run large or small.
2. Examine the Company’s Sizing Guide
As different brands may have different sizing guidelines, it is important to review the particular sizing guide that the company has given. They frequently have this information on their website.
3. Examine the Content
The shoe’s substance may have an impact on fit. For instance, leather shoes have the potential to stretch with time, so you may need to start with a somewhat tighter fit.
4. Measure your Feet in the Afternoon
It is scientifically proven that our feet expand throughout the day. With that being said, it’s a good idea to measure your feet in the afternoon or evening when they are at their largest size.
5. Wear your Intended Socks
You must wear your intended socks while measuring your foot. Why? This will give you some margin in your shoe size so that you don’t get too snuggly fitting. And one more important thing is you should go one size up to give your toes some wiggle room (my personal advice).
6. Look for Return Policies
A flexible return policy might come in handy if the pair you’ve chosen doesn’t fit as intended. Prior to making a purchase, review the online store’s return policies.
