How to find out my shoe size

Updated February 21, 2017

Improperly-fitting shoes can cause blisters, bunions, hammer toes, calluses and foot pain. Your shoe size may have changed if you’ve gained or lost weight, worn the same shoes for a while or frequently walk barefoot. Before buying that new pair of shoes, check your current size to ensure a proper fit.

Tape a large, blank sheet of paper to the floor to keep it from sliding.

Place your bare foot in the middle of a sheet. Trace around your foot with a pencil. Repeat with your other foot.

Measure the length of the tracings at their longest point. Reduce this measurement by 5 mm (1/5 of an inch) to account for the width of the pencil and the small gap between your foot and the pencil line.

Measure the two widest points of the tracings. Reduce by 5 mm (1/5 of an inch).

Look up your shoe size in a size conversion chart that translates foot measurements into shoe sizes. Size conversation charts are available at shoe shops and online.


Always try on shoes before buying. Sizes can vary between brands and manufacturers.

Measure your feet at the end of each day, when feet tend to be their largest.
