Size Chart - BK - Knit-Rite Prosthetic Sheath

Step 1: Top & Bottom

Measure the circumference around the middle of your knee cap and 2 inches up from the bottom of your residual limb.  The bottom circumference is the most difficult to measure because it may feel as if the tape measure is sliding off your limb.

Step 2: Length

Length is a matter of preference. However, the typical rule is 2-3 inches past the middle of your knee cap.


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. Most below-knee amputees fit a size "Regular."
