What is the method of feet measurement?

Answer 1

When measuring feet you should use a foot measuring device which has a cup for the heel, a flat foot base plate for the base of the foot and a slider that can be brought up to the furthest extension of the toes. The slider should provide a marker to a graduated scale on the foot base plate which shows how long the foot is in inches/mm/or shoe size. Frequently a foot measure will also have a tape that can go round the widest part of the toes to give a shoe with guide.

When measuring feet, measure both feet with the person sitting then standing as the foot length will change and many people have different sized feet.
