Orthopedic Medical Cast Stockinette 7.5 cm wide (full roll 22 meters)
for sizing: Need to know what size stockinette to order. Simply
measure the circumference of your leg or arm. Stockinette is measured
in width so basically it is the diameter value.
7.5 cm is mostly used in long arms casts. If you have a very large arm, you may want to use 10 cm. For a child, 5 cm would be better for the arm.
