Navigating the world of shoe sizes can often feel like deciphering a secret code. Different regions use different sizing systems, and it’s not always straightforward to convert between them. If you’ve ever found yourself wondering, “What is a size 40 in US shoes?”, you’re not alone. This guide will clearly explain European (EU) to US shoe size conversions, with a special focus on understanding what a Euro size 40 means in US sizing.
Understanding Shoe Size Systems: US, EU, and UK
Before we dive into the specifics of US size 40 and its European equivalent, it’s helpful to understand the primary shoe sizing systems you’ll encounter:
- US Sizes: Predominantly used in the United States, these sizes are numbered and differentiate between men’s, women’s, and children’s sizes.
- European (EU) Sizes: Commonly used in Europe, these sizes are based on a system called Paris points, where one Paris point is 2⁄3 of a centimeter. EU sizes are generally the same for men and women, though some brands might have slight variations.
- UK Sizes: Used in the United Kingdom, these sizes are also numbered and are generally smaller than US sizes.
Knowing these systems exist is the first step in ensuring you choose the right shoe size, no matter where you are buying from.
Converting US Size 40 to European Size: Women’s and Men’s
The question we’re tackling is specifically about the conversion from US to European sizes, particularly focusing on size 40. Let’s break it down for both women’s and men’s shoes:
For Women:
If you are looking at women’s shoes and wondering what a US size 40 translates to in European sizing, you’re actually looking at the conversion in reverse! European size 40 in women’s shoes corresponds to a US size 9 or 9.5.
Here’s a quick look at the relevant portion of a women’s shoe size conversion chart:
| US Sizes | Euro Sizes | UK Sizes | Inches | CM |
|---|---|---|---|---|
| 9 | 39-40 | 7 | 9.875″ | 25.1 |
| 9.5 | 40 | 7.5 | 10″ | 25.4 |
| 10 | 40-41 | 8 | 10.1875″ | 25.9 |
As you can see, a women’s US size 9.5 is directly equivalent to a European size 40. If you are sometimes a US size 9 and sometimes a 9.5, and you see a Euro size 40, it’s likely to fit, potentially being a touch more generous than a strict US size 9.
For Men:
Now, let’s consider men’s shoes. If you’re trying to convert “40 Us To Eur” in the context of men’s sizes, again, it’s the reverse. European size 40 in men’s shoes corresponds to a US size 7 or 7.5.
Here’s the relevant section from a men’s shoe size conversion chart:
| US Sizes | Euro Sizes | UK Sizes | Inches | CM |
|---|---|---|---|---|
| 7 | 40 | 6.5 | 9.625″ | 24.4 |
| 7.5 | 40-41 | 7 | 9.75″ | 24.8 |
| 8 | 41 | 7.5 | 9.9375″ | 25.4 |
For men, a US size 7.5 is very close to a European size 40. Similar to women’s sizing, if you fluctuate between a US size 7 and 7.5, a Euro size 40 could be a good fit, potentially leaning slightly towards a US 7.5.
Understanding these nuances is crucial, especially when shopping online where trying shoes on isn’t an option.
Measuring Your Feet for Accurate Shoe Size Conversion
While conversion charts are incredibly helpful, the most accurate way to determine your shoe size is by measuring your feet. Here’s a simple method you can use at home:
- Place a piece of paper: Put a piece of paper larger than your foot on the floor against a wall.
- Position your foot: Stand on the paper with your heel against the wall.
- Mark the longest point: Have someone trace the outline of your foot, or mark the longest point of your toes.
- Measure the length: Use a ruler or measuring tape to measure the distance from the edge of the paper (where your heel was) to the longest marking.
- Compare to charts: Use the inch or centimeter measurement and refer to a detailed shoe size chart (like the ones provided earlier) to find your US and European size.

Measuring both feet is also recommended, as many people have slight differences in foot size. Always fit shoes to the larger foot.
Tips for Choosing the Right Shoe Size After Conversion
Converting “40 us to eur” or any shoe size is a great starting point, but consider these additional tips for a perfect fit:
- Size Up if in Doubt: If you are between sizes, especially for athletic or hiking shoes, it’s generally better to size up. This allows for sock thickness and foot swelling during activity.
- Account for Brand Variations: Shoe sizes can vary slightly between brands. A US size 9 in one brand might feel a bit different in another. If you’re familiar with a brand, consider their sizing tendencies.
- Consider Shoe Type: The type of shoe matters. Running shoes might require a slightly larger size than dress shoes. Hiking boots often need to accommodate thicker socks.
- Try Shoes On in the Afternoon: Your feet tend to swell throughout the day. Trying on shoes in the afternoon or evening can help ensure a comfortable fit when your feet are at their largest.
- Check Width as well as Length: While size charts primarily focus on length, width is also crucial. Some brands offer different width options. If you know you have wider feet, look for brands that cater to this.
Conclusion: Euro Size 40 in US Shoes – Clarity and Confidence
Understanding shoe size conversions, particularly “40 us to eur,” empowers you to shop for footwear globally with greater confidence. Remember, a European size 40 translates to approximately a US women’s size 9.5 and a US men’s size 7.5. By using conversion charts, measuring your feet, and considering practical fitting tips, you can step out in comfort and style, no matter the sizing system. Whether you’re buying online or in a store abroad, you’re now better equipped to find your perfect shoe fit.
