Step-by-step instructions

Place a piece of paper on a hard, flat floor with one end against a wall.
Stand on the paper with your heel touching the wall. Weight should be even.
Mark the paper at the tip of your longest toe (use a pencil held vertically).
Measure from the wall to the mark in centimeters. Use a ruler or our printable sheet.
Repeat for the other foot. Use the larger measurement for shoe size.
Convert your measurement using our Shoe Size Converter or CM to US Shoe Size tool.
