It is important for the health and comfort of your feet to know the proper measurements of your foot. This will help you to determine the proper shoe size to wear. The width of your foot is measured from one side of your foot to the other, not from the front of your foot to the back. That is known as the length of your foot. Most shoes sizes revolve around length, but you can find wider or narrower shoes if need be.

Measure with the ruler from the two farthest points on the side of your foot. These points are near your toes. Do not include your toes in the measurement. The measurement you arrive at is the width of your foot. Due to the scale of your foot, you should use inches to take the measurement.
Choose your width size. This varies based on your actual shoe size. Your measurement and your shoe size determines if you are a "C," "M/D" or "E." Refer to the Resources section of this article to correspond your measurement to the appropriate letter width for your foot.
