Shoe Size Converter

Shoe sizing systems vary significantly by country, and the same foot length produces different size numbers depending on which standard is used. Accurate conversion prevents ordering the wrong size when shopping internationally.

Key formulas:

Foot Length to US Men’s Size: US Men’s = (Foot Length in inches × 3) − 22

Foot Length to US Women’s Size: US Women’s = (Foot Length in inches × 3) − 21

US Men’s to EU Size: EU = US Men’s + 33

EU to UK Men’s: UK Men’s = EU − 33

Mondopoint (used in athletics and some European standards): Mondopoint = Foot Length in mm (e.g., a 270 mm foot = size 270)

What each variable means:

• Foot Length — measured from the back of the heel to the tip of the longest toe (in inches or cm).
• Width — separate from length; US standard widths: 4A (narrowest) to 6E (widest); medium is B/D.
• Last — the 3D form shoes are built on; different brands use different lasts, so sizes vary between brands even in the same nominal size.

Conversion reference table:

Measurement tip: Measure both feet standing up at the end of the day (feet swell slightly). Use the larger foot. Always try shoes on when possible — conversions are approximations, and fit varies by brand and style.
