Jobst sizes its compression stockings according to the circumference of the ankle, calf, thigh and hip of the wearer. The company also produces a large-tall size for individuals with a shoe size larger than 12.
To find the correct size for Jobst knee-high compression stockings, start by measuring the circumference of the ankle. Place the measuring tape at the narrowest part of the ankle, usually directly above the ankle bone. Next, find the widest part of the calf and measure its circumference. Finally, with the wearer sitting with her legs bent at a 90-degree angle, measure the length of the leg from the bottom of the foot to the middle of the knee.
For thigh-high stockings and pantihose, find the circumference of the ankle, calf and thigh. Wrap the measuring tape around one thigh just below the buttocks. With the patient standing, measure the length of the legs from the floor to the bottom of the buttocks.
The size charts for different models of Jobst stockings may vary slightly. In general, a small size fits ankle circumference of 7 to 8 1/4 inches and calf circumference of 11 to 15 inches. Regular knee-high stockings fit legs that are longer than 15 inches from foot to knee, while regular thigh-high stockings fit legs that are longer than 27 inches from foot to buttocks.
