STEP 1: Measure Circumferences
Measure the circumference along three areas of your limb. First begin measuring the circumference 6 inches above your knee cap. Second measure the circumference around the middle of your knee cap. And last, measure the circumference 2 inches (5cm) up from end of your residual limb. Continue to STEP 2: Length
STEP 2: Length
Length is a matter of preference, however the general rule is 2 inches past your knee cap. Continue to STEP 3: Find your size
STEP 3: Find your size
Take all of your circumference 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.
