us to uk sizes shoes
Buying shoes online should feel exciting, but for many shoppers, the sizing differences between countries can turn the process into a guessing game. One of the most common issues people face is trying to figure out US to UK sizes shoes a small detail that can easily lead to uncomfortable footwear, returns, and unnecessary frustration.
If you regularly shop across international websites or follow global brands, learning these conversions is a simple way to avoid surprises. This guide breaks everything down in a clear and friendly way, so you can shop confidently and choose the right fit the first time.
Why US and UK Shoe Sizes Don’t Match
Although the two systems look similar, they don’t line up perfectly. Historically, each country built its own measurement standards based on different “lasts” (the foot-shaped blocks used in shoemaking). Over time, those standards stayed in place even as brands expanded globally.
Here’s the quick version:
- Men’s shoes: US sizes are usually one size bigger than UK.
- Women’s shoes: US sizes are usually two sizes bigger than UK.
- Kids’ shoes: These vary more than adult sizes because brands use different internal systems.
That small difference, even just half a size, can completely change how a shoe feels on your feet.
Men’s US to UK Shoe Size Conversion
Most men’s shoes follow a simple pattern. If you know your US size, subtracting one will give you the closest UK match.
| US Size | UK Size |
|---|---|
| 6 | 5 |
| 7 | 6 |
| 8 | 7 |
| 9 | 8 |
| 10 | 9 |
| 11 | 10 |
| 12 | 11 |
| 13 | 12 |
This works for most popular brands, but some athletic shoes may run slightly small or large depending on the model.
Women’s US to UK Shoe Size Conversion
Women’s sizing shifts by two numbers, which often causes more confusion than men’s sizes.
| US Size | UK Size |
|---|
| 5 | 3 |
| 6 | 4 |
| 7 | 5 |
| 8 | 6 |
| 9 | 7 |
| 10 | 8 |
| 11 | 9 |
If you’re buying unisex shoes, remember that unisex sizing follows men’s standards, not women’s, so use the men’s chart for accuracy.
Kids’ US to UK Shoe Size Conversion
Children’s shoes are trickier because every brand treats smaller sizes differently. Still, here’s a general guide:
| US Kids Size | UK Size |
|---|
| 10 | 9 |
| 11 | 10 |
| 12 | 11 |
| 13 | 12 |
| 1 | 13 |
| 2 | 1 |
| 3 | 2 |
| 4 | 3 |
| 5 | 4 |
When it comes to kids, it’s always better to double-check the brand’s own chart, because their feet grow fast and sizing isn’t always consistent.
How to Measure Your Foot the Right Way
A lot of sizing issues come from inaccurate measurements rather than bad conversions. Before converting US to UK sizes shoes, take a moment to measure properly:
- Place a piece of paper against a wall.
- Stand on it with your heel touching the wall.
- Mark the longest toe.
- Measure the distance in centimeters or inches.
- Compare this number with the brand’s size guide.
One foot is usually slightly bigger than the other, so measure both and go with the larger number.
Why Width Plays a Bigger Role Than People Think
We often obsess over the length of the shoe, but width can be just as important. You might get the size right but still feel tightness or pressure if the shoe doesn’t match your foot width.
- US widths use letters like N, M, W, XW.
- UK widths often use letters like E, F, G, H.
Since the systems don’t match perfectly, sometimes you’ll need to adjust the width when converting sizes.
Differences Between Popular Brands
Every brand has its own personality when it comes to sizing. Here’s a quick overview of what to expect:
Nike
Tends to run slightly small, especially in athletic models.
Adidas
Generally true to size, though some lifestyle shoes may feel roomy.
New Balance
Offers more width options than most brands and is usually accurate.
Dr. Martens
Because it’s originally a UK brand, the sizing sometimes confuses US buyers—many people end up going down a full size.
These small differences explain why two shoes listed at the same US size may feel completely different on your feet.
Common Mistakes When Converting Shoe Sizes
People usually run into the same problems:
- Ignoring width
- Forgetting that unisex shoes follow men’s sizes
- Assuming every brand uses the same conversion
- Choosing a size based purely on past experience
- Not checking return policies before ordering
It takes only a few minutes to compare sizes but saves you days of hassle.

- Read reviews that mention “runs small” or “true to size.”
- Compare your foot length with the brand’s chart—not just the conversion table.
- Shop from stores that offer easy returns or exchanges.
- If you’re between two sizes, most people prefer going up, especially for everyday shoes.
