Women's to Men's Shoe Size Conversion Calculator Online
If you've ever tried to cop a pair of exclusive sneaker drops, you already know the struggle. The colorway you want is only released in men's sizing, or you're eyeing a unisex pair of sneakers and have no idea which box to check at checkout.
Buying shoes across gender categories shouldn't require a math degree. Whether you are trying to figure out your size in Jordans, Sambas, or running shoes, getting the fit right is crucial. Not only is the length different, but the standard width varies too.

How to Compare Men's Shoe Size with Women's
When you compare men's and women's shoes, you are looking at two main differences: length and width.
In the United States, men's and women's shoe sizes are not on the same scale. A men's size 8 is significantly longer than a women's size 8.
Furthermore, the standard width for a women’s shoe is a "B" width (Medium), while the standard width for a men’s shoe is a "D" width (Medium). This means if you are a woman buying a men's shoe, the fit might feel slightly roomier or wider in the toe box and heel than you are used to.
If you have particularly narrow feet, you might need to wear thicker socks or lace the shoes tighter when converting to a men's size. If you have wide feet, switching to men's sizes might actually give you a much more comfortable fit!
What is the Women's Equivalent to Men's Shoe Size?
For the vast majority of footwear brands in the USA, the standard rule of thumb is a 1.5 size difference.
To find the women's equivalent to a men's shoe size, you simply add 1.5 to the men's size. Conversely, to find your men's size if you are a woman, you subtract 1.5 from your women's size.
- Example 1: A Men's Size 7 is a Women's Size 8.5.
- Example 2: A Women's Size 10 is a Men's Size 8.5.

If you are shopping in the US, the 1.5 size rule applies to almost all major brands, including Puma, New Balance, Asics, Mizuno, and Reebok. Here is a quick reference chart for standard US shoe size conversions:
| US Women's Size | US Men's Size | EU Equivalent | Foot Length (cm) |
|---|---|---|---|
| 5.0 | 3.5 | 35.5 | 22.0 cm |
| 6.0 | 4.5 | 36.5 | 23.0 cm |

| 10.0 | 8.5 | 42.0 | 27.0 cm |
Women's to Men's Shoe Size Conversion Calculator UK
Here is where things get significantly easier. In the United Kingdom, men's and women's shoe sizes are exactly the same.
The UK uses a unisex sizing system. Therefore, a UK Women's size 6 is identical in length to a UK Men's size 6. If you are shopping on a UK-based website or looking at the UK size on a shoe box tag, you don't need to add or subtract any numbers.
| UK Women's Size | UK Men's Size | EU Equivalent |
|---|---|---|
| 4.0 | 4.0 | 36.5 |
| 5.0 | 5.0 | 38.0 |
| 6.0 | 6.0 | 39.0 |
| 7.0 | 7.0 | 40.5 |
Women's to Men's Shoe Size Conversion Calculator Nike
Nike is perhaps the most popular brand for cross-gender shoe shopping, especially with models like the Air Force 1, Nike Dunk Low, and Air Jordan Retros.
Nike strictly adheres to the standard 1.5 size difference rule in the US. If you are a woman trying to buy a men's Jordan 1 or a unisex Nike silhouette, you need to size down by 1.5.
Nike Sizing Examples:
- If you wear a Women's 9 in Nike, buy a Men's 7.5.
- If you wear a Women's 7.5 in Nike, buy a Men's 6.0.
Women's to Men's Shoe Size Conversion Calculator Adidas
Attention: This is where most people make a mistake!
Unlike Nike and the rest of the industry, Adidas uses a 1-size difference for their US men's and women's conversions (Hoka also uses this 1-size rule).
If you apply the standard 1.5 rule to Adidas shoes (like Sambas, Gazelles, or Yeezys), your shoes will end up being too small. When converting a women's Adidas size to a men's Adidas size, you only subtract 1 full size.
Adidas Sizing Examples:
- If you wear a Women's 9 in Adidas, buy a Men's 8.
- If you wear a Women's 10 in Adidas, buy a Men's 9.
| Adidas US Women's | Adidas US Men's |
|---|---|
| 6.0 | 5.0 |
| 7.0 | 6.0 |
| 8.0 | 7.0 |
| 9.0 | 8.0 |
| 10.0 | 9.0 |
Frequently Asked Questions (FAQs)
Are men's and women's shoe sizes the same?
No, in the US, men's and women's shoe sizes are different. A men's size is typically 1.5 sizes larger than the same number in women's (e.g., a Men's 7 is a Women's 8.5). However, in the UK, men's and women's size numbers are identical.
Is a men's size 8 the same as a women's size 8?
No. In the US sizing system, a men's size 8 is much larger. A men's size 8 is equivalent to a women's size 9.5.
Do men's shoes fit wider than women's?
Yes. The industry standard width for women is "B" (Medium), while the standard width for men is "D" (Medium). A men's shoe will generally feel wider in the heel and toe box compared to a women's shoe of the exact same length.
How do I convert women's to men's shoe size in EU sizing?
You don't have to! European (EU) sizing is completely unisex. An EU size 40 is the exact same size regardless of whether the shoe is marketed toward men or women. This makes EU sizing the most accurate way to buy shoes across gender lines.
