Size Chart - Knit-Rite BK 4-Way

Step 1: Measure Circumferences

How to measure for a Knit-Rite Prosthetic Shrinker.

Measure the circumference along three areas of your limb. First begin measuring the circumference 6 inches (15cm) above the middle of your knee cap. Second measure the circumference around your knee cap. And last, measure the circumference 2 inches (5cm) up from the bottom of your limb.

 

Step 2: Length

Length is a matter of preference. However, a good rule is to select a length that is 2-3 inches past your knee cap.

 

Step 3: Find your size

Take all of your circumference and length measurements and use the chart below to determine your size. If you're in-between sizes, we suggest remeasuring again to be on safe side.
