Step 1 Collect your supplies. A large piece of paper bigger than both your feet, sticky masking tape or scotch tape, a ruler, pen or pencil, and notepaper to mark your measurement numbers down.

Step 2
Place the large piece of paper on the floor and smooth it out so it is flat.

Step 3
Tape the corners of your large piece of paper securely to the floor so it won't move around when you stand on it.

Step 4
Take off your shoes. You can leave on the socks you will be wearing with your new shoes.

Step 5
Have your small piece of note paper, pen or pencil within easy reach.

Step 6
Stand in the middle of the large piece of paper with a few inches of space between both your feet. Make sure your feet are placed firmly on the floor. Don't wiggle or curl your toes.

Step 7
Take your pen or pencil and trace the outline of one foot onto the paper you are standing on. Make sure your pen or pencil is straight up and down and firmly against your foot as you trace your outline. (Sometimes it is easier to have another person do the tracing for you, but it can be done by yourself.)

Step 8
Repeat the above step with your other foot.

Step 9
Now you will remove the taped paper from the floor and put it flat down on a table or place where you can take your ruler to get the exact numbers. If your ruler has centimeters that can give a more accurate measurement.

Step 10
For your length, place your ruler at the bottom to the top of one of the traced outlines. (Base of heel to tips of toes.)

Step 11
Draw a straight line from top to bottom of the outline. Mark this length measurement on your notepad paper.

Step 12
Then draw a straight line going side to side at the widest part of the outline. Mark this width measurement down on your notepad paper.

Step 13
Repeat steps 9 to 11 for your other foot traced outline.

Step 14
You will want to use the largest length measurement for your shoe size!

Step 15
Finally, convert the measurement to your shoe size -- see the women's shoe size chart below.
