STEP 1: Top & Bottom
Measure the circumference around the middle of your knee cap and 2 inches up from the end of your residual limb. Continue to STEP 2: Length
STEP 2: Length
Length is a matter of preference. However, the typical rule is 2-3 inches past the middle of your knee cap. Continue to STEP 3: Find your size
STEP 3: Find your size
Take both your top, bottom, and length measurements and use the chart to determine your size. If you're in-between sizes, we suggest remeasuring again to be on safe side. Size Regular is typically worn by below-knee prosthesis users.
