  2. Stand on the paper with your heel against the wall.

Measure foot length and width
  • Use a ruler to measure the length from the heel line to your longest toe mark.
  • Measure the width at the widest part of your foot trace.
  • Pro Tip: Subtract 0.2 inches (5mm) from length to account for the pencil width.
