Conversion

• In the United States, women's shoe sizes are standardly two whole sizes smaller than men's sizes. For example, a men's size 8 shoe would equal a women's size 10.
  
  

Measurements

• Shoe sizes are determined by the length of your foot in inches or centimeters. A women's size 8, for example, is equal to about 9 ½ inches, while a men's size 8 is equal to about 10 inches.
  
  

International Sizes

• The difference between sizes varies in different nations. In Europe, for instance, men's and women's shoes can vary from between one-half to a whole size. Because nations have different sizing guides, you will need to use the guide for that location to determine shoe sizes.
  
  

Kids

• Children's sizes do not differentiate between boys and girls. Sizes lower than size 5 in both men and women's shoes are typically considered children's, and the sizes are the same for boys' and girls' shoes.
  
  

Tips

• Because different manufacturers may have slight variations in shoe sizing, the conversion may not be 100 percent accurate for every shoe. It is best to try on the shoe, even after using the conversion method, to ensure a proper fit.
