1. Measure the circumference of your arm at 2 inches above the cast or wound. If this is at the elbow, then measure above the elbow. The cast cover will not work if sealed at the elbow.
2. Measure the length from your fingertips to 2 inches above the cast or wound. As long as the length of the cast cover is longer than your measurement, you are good to go! Any excess material in length will be shrunken down with the vacuum seal.
