How Shoe Sizing Works
US and UK
Both use the barleycorn system: size 0 is ~12 barleycorns (4 inches). Each size adds 1/3 inch. UK men's and women's sizes differ by 1.5-2.5 sizes.
EU (Mondopoint)
EU sizes are based on the length of the foot in centimeters plus a small allowance. EU size = foot length (cm) × 1.5 + 2.
CM (Mondopoint child)
Direct centimeter measurement of the foot. Common in Asia and for kids' shoes worldwide.
