How to Convert Shoe Sizes Between US, UK, and EU Standards

When it comes to buying shoes, especially online, one of the most confusing aspects can be understanding how shoe sizes differ across various regions. For example, a size 8 in the US might not be the same as a size 8 in the UK or the EU. This inconsistency can make shopping for shoes internationally or even domestically a bit of a challenge. The good news is that converting shoe sizes between US, UK, and EU standards isn’t as complicated as it seems once you understand the differences and know how to make the conversions.

We’ll dive deep into how shoe sizes work across these three regions—US, UK, and EU—and how to easily convert between them. We’ll also provide a conversion chart and answer some frequently asked questions to ensure you can shop for shoes with confidence.

Understanding the Different Shoe Sizing Systems

Before we start converting shoe sizes, it’s important to first understand how shoe sizing systems work in the US, UK, and EU.

US Shoe Size System:

The United States follows a numerical sizing system for shoes, and the sizing generally refers to the length of the shoe in inches or centimeters. For men, women, and children, the sizing systems are different, which is why it’s important to distinguish between men’s and women’s shoe sizes. Typically, US sizes are measured based on the length of the foot in inches, with each number representing a specific length increment.

For example:

Men’s US shoe size 9 would be approximately 10.5 inches in length.
Women’s US shoe size 9 would be about 9.25 inches in length.

UK Shoe Size System:

In the UK, shoe sizing is slightly different. UK sizes are also based on foot length, but the sizing system starts differently and uses a different scale than the US. UK shoe sizes tend to run about one size smaller than their US counterparts.

For example:

Men’s UK shoe size 9 would be roughly the same as US men’s shoe size 10.
Women’s UK shoe size 9 would correspond to US women’s shoe size 11.

EU Shoe Size System:

The European Union (EU) uses a different standard altogether, known as the Paris Point system. EU sizes are based on the length of the foot in centimeters, multiplied by a factor of 1.5. The EU shoe sizing system does not differentiate between men’s and women’s sizes, so the same number applies for both genders.

For example:

EU shoe size 42 is roughly equivalent to US men’s size 9 and US women’s size 11.
EU shoe size 38 is approximately US women’s size 7.

The EU system is often more consistent, especially for unisex shoes, because it doesn’t change based on gender.

How to Convert Shoe Sizes Between US, UK, and EU Standards

Now that we understand how the systems work, let’s look at how to convert between US, UK, and EU shoe sizes. We’ll walk you through the most common conversions and also provide a simple chart to help guide your shoe-shopping experience.

1. Converting US to UK Sizes

To convert from US shoe sizes to UK shoe sizes, you can simply subtract one size for both men and women. This is because UK shoe sizes generally run one size smaller than US sizes.

US to UK Conversion Formula:

Men’s US size – 1 = UK size
Women’s US size – 1 = UK size

Here’s a quick example:

US men’s size 10 = UK men’s size 9
US women’s size 8 = UK women’s size 7

2. Converting US to EU Sizes

Converting from US sizes to EU sizes can be a bit more tricky because the EU system works differently. However, it’s easy to convert if you know the approximate equivalents.

US to EU Conversion Formula:

For Men’s shoes: US men’s size + 33 = EU size
For Women’s shoes: US women’s size + 31 = EU size

Here’s how it works in practice:

US men’s size 9 = EU size 42
US women’s size 8 = EU size 39

3. Converting UK to US Sizes

Converting UK shoe sizes to US shoe sizes is quite straightforward. Since UK sizes are one size smaller than US sizes, you simply add one size to convert from UK to US sizes.

UK to US Conversion Formula:

Men’s UK size + 1 = US size
Women’s UK size + 1 = US size

Example conversions:

UK men’s size 9 = US men’s size 10
UK women’s size 7 = US women’s size 8

4. Converting UK to EU Sizes

To convert UK sizes to EU sizes, you can follow a relatively simple formula. EU sizes are larger than UK sizes, and there’s a direct correlation that’s easy to follow.

UK to EU Conversion Formula:

For Men’s shoes: UK men’s size + 33 = EU size
For Women’s shoes: UK women’s size + 31 = EU size

Example:

UK men’s size 9 = EU size 42
UK women’s size 7 = EU size 38

5. Converting EU to US Sizes

Converting EU sizes to US sizes requires a bit more calculation. EU sizes are generally larger than US sizes, so you need to subtract a specific amount to get the US size equivalent.

EU to US Conversion Formula:

For Men’s shoes: EU size – 33 = US men’s size
For Women’s shoes: EU size – 31 = US women’s size

Here’s how the conversion works:

EU size 42 = US men’s size 9
EU size 39 = US women’s size 8

6. Converting EU to UK Sizes

Finally, converting EU sizes to UK sizes is relatively simple because the EU sizing system is based on a consistent scale.

EU to UK Conversion Formula:

For Men’s shoes: EU size – 34 = UK size
For Women’s shoes: EU size – 33 = UK size

Example conversions:

EU size 42 = UK men’s size 8
EU size 39 = UK women’s size 6

7. Frequently Asked Questions

1. Do all shoe brands follow the same sizing charts?
No, not all shoe brands use the same sizing standards. Some brands may have their own sizing systems, which can cause slight variations in fit. It’s always a good idea to check the brand’s specific size guide before purchasing.

2. How do I measure my foot for the correct shoe size?
To measure your foot, place a piece of paper on the floor, stand on it, and trace the outline of your foot. Measure the distance from the heel to the tip of your longest toe. Use a size chart to determine your shoe size based on your foot length.

3. Why do European sizes appear bigger than US sizes?
European shoe sizes are based on a different scale and use a 1.5 cm increment for each size. The system is more consistent, but it results in a larger number compared to US sizes.

4. How do I know if I’m choosing the right size when shopping online?
Make sure to check the shoe size guide for the specific brand you’re purchasing from, as different brands may have slight size differences. Also, look for customer reviews to see if the shoes run large or small.

5. Are there shoes that fit both US and UK sizes?
Some international shoe brands offer “unisex” sizing or shoes that follow a standard size conversion chart. However, it’s still important to double-check the sizing guide.

6. How often should I check my child’s shoe size?
Children’s feet grow quickly, so it’s recommended to measure their feet every 2-3 months to ensure their shoes fit properly.

7. Can I wear shoes with a different country’s size if I use the conversion chart?
Yes, the conversion chart should give you a pretty accurate fit. However, individual shoe brands may vary slightly, so always check the return policy when purchasing shoes from a different region.
