1) Gather Your Supplies



All you need to get your proper foot measurement at home is:
  • a piece of paper larger than your foot
  • a pencil
  • tape
  • and a ruler or measuring tape


    • Tape the paper down to the floor

    2) Tracing Your Foot to Find Your Shoe Size



    a) Sit on a chair with your foot firmly on the floor, and your leg bent slightly forward so that your shin is slightly in front of your ankle.
    b) Trace the outline of your foot and remember to measure your foot without shoes, but with socks similar to the ones you'll be wearing with the boots that you will be buying.
    c) Hold the pencil or pen upright and perpendicular to the paper. Do not hold it at an angle. Make sure the pencil is resting snugly against your foot as you draw around it.
    d) You may actually find it helpful to have someone else trace your foot, but as you can see in this image, it can be done alone.

    3) Mark the Length of Your Foot



    a) Use your pencil or pen to draw straight lines touching the outermost points at the top and bottom of the outline.

    4) Measure the Length of Your Foot



    a) Use your ruler or measuring tape to measure the length from the bottom line to the top line that you drew in step three.

    b) Be sure to hold the measuring tape straight, and find the closest mark that you can (for inches, use the closest 16th mark) - don't round up or down dramatically.

    Write this number down.

    5) Finding the Final Boot Size

    a) Repeat these steps for your other foot, and use the larger of the two.

    b) After you have your numbers written down, you'll want to subtract 2 tenths of an inch from the numbers. This is to accommodate for the slight space between your actual foot and the line made by the pencil.

    c) These final numbers are your actual foot measurements, you can convert them to the appropriate size by using the conversion chart at the top of the page.
