How to Measure Your Foot Accurately at Home
Relying on a standard conversion tool is helpful, but measuring your feet in centimeters provides the most accurate fit—especially when using systems like Mondopoint. Follow these steps:
- Grab your supplies: You need a blank piece of paper, a pen, and a ruler or measuring tape.
- Place the paper on the floor: Tape it down so it doesn’t slide, and place the short edge flush against a wall.
- Stand on the paper: Ensure your heel is pressed lightly against the wall. Do this wearing the type of socks you intend to wear with the shoes.
- Mark your longest toe: Have someone else draw a line at the tip of your longest toe (or do it yourself by leaning forward slightly).
- Measure the length: Use your ruler to measure from the edge of the paper (the heel) to the line you drew. Write this down in centimeters.
Pro-tip: Most people have one foot slightly larger than the other. Measure both feet and buy shoes based on the larger foot!
Brand Variations: Why Your Size Might Fluctuate
Even armed with exact conversions, you may find that a size 9 fits perfectly in one brand but crushes your toes in another.
- Nike: Typically runs slightly small and narrow. Many shoppers size up by half a size.
- Adidas: Generally true to size, though certain models (like Yeezys) require sizing up.
- New Balance: Known for excellent true-to-size fits and offering a wide variety of specific width options.
- Designer Brands (Gucci, Prada, etc.): European luxury brands often run a full size larger than standard US athletic sneakers.
Understanding the Different Shoe Sizing Systems
Before making a purchase, it helps to understand why shoe sizing is so different globally:
- United States (US): The American shoe sizing system is historically based on the length of the last (the mold used to shape the shoe), measured in “barleycorns” (an old English unit). It is often accurately measured in modern times using a Brannock Device.
- United Kingdom (UK): The UK system is similar to the US system in its origins but is usually 0.5 to 1 size smaller for men, and 2 sizes smaller for women.
- European Union (EU): EU sizes are based on the Paris Point, which equates to 2/3 of a centimeter. This system does not differentiate between men and women—a size 40 is a size 40 regardless of gender.
- Japan (Mondopoint): The Mondopoint standard is arguably the most logical system. It simply measures the length of your foot in millimeters or centimeters. If your foot is 26cm long, your Japanese shoe size is 26.
- Australia (AU): Australia’s sizing system is a hybrid. Men’s sizes are identical to UK men’s sizes, while women’s sizes align closely with US women’s sizes.

Frequently Asked Questions
Can I rely on online shoe size conversion tools?
Online converters provide an excellent baseline, but sizing can still vary by brand. A Nike size 10 might feel different than an Adidas size 10. Always look for the brand’s specific “Fit Guide” before completing your purchase.
What is a US Men’s size 9 in EU?
A US Men’s size 9 generally converts to an EU size 42.5 or 43, depending on the manufacturer.
Is UK shoe sizing the same as US?
No. For men, US sizes are generally 0.5 to 1 full size larger than UK sizes (e.g., US 10 = UK 9.5). For women, US sizes are typically 2 sizes larger than UK sizes (e.g., US 8 = UK 6).
How can I measure my foot accurately for shoe size conversion?
Use a ruler or measuring tape to measure the length of your foot in centimeters or inches.
What should I do if I’m between sizes in different conversion systems?
If you fall between sizes or have one foot slightly larger than the other, the golden rule in footwear is to opt for the larger size. You can always wear thicker socks or use an insole, but a shoe that is too tight will cause blisters and restrict blood flow.
