Birkenstock Sizing Guide

Birkenstock Logo
  • Measure the length of your foot by standing on a flat surface with your full weight on your foot, then measure the distance from the back of your heel to the tip of your longest toe.
  • Add 10mm to your foot length to allow your foot room to move. This will give you the footbed length you need to find your size.
  • Measure the width of your foot across the broadest point. Compare your foot width measurement to the footbed width in your size to see if you will need a narrow or regular width.
Example: Julie's foot measures 180mm long. Julie adds 10mm to her foot's length to find she will fit comfortably into a Size EU30 (190mm Footbed Length).


For assistance with measuring your child's feet please visit our Sizing Information page

Note: In the adult sizes we suggest going up a size in the narrow style vs regular. The only style available in a narrow option is the Arizona. We have reflected this in the Women's sizing conversion.
