Our shoe size calculator makes it simple to determine your ideal shoe size. Enter your foot measurements, and the tool instantly provides your size in US, UK, EU, AUS, MEX, and Korean standards.
This calculator helps you accurately convert and find your shoe size across multiple international systems, including US/CA, UK, EU, and more.
If you already know your size in one system (for example US), you can quickly convert it to other systems such as EU or UK in seconds.
Follow these steps to find your correct shoe size:
Note: If you know your US size, select “US” from the dropdown before calculating.
You can measure your feet manually at home to get accurate results:
If your foot measures 22.5 cm (≈8.86 inches), your shoe size can be calculated as follows:
EU = (Foot length cm + 2 × 0.667) ÷ 0.667
EU = (22.5 + 1.334) ÷ 0.667 ≈ 35.9
UK = (3 × Inches) - 23
UK = (3 × 8.86) - 23 ≈ 3.6
US = (3 × Inches) - 22
US = (3 × 8.86) - 22 ≈ 4.6
US Men = (3 × Inches) - 22
US Women = (3 × Inches) - 21
US Kids = (3 × Inches) - 9.67
UK Adults = (3 × Inches) - 23
UK Kids = (3 × Inches) - 10
EU Size = 1.27 × (UK Size + 23) + 2

In the US system, women’s sizes are typically 1 size smaller than men’s. For example, a women’s size 8 roughly equals a men’s size 7. Exact differences may vary by brand. Use the calculator to get precise conversions.
