More on How to Measure

Measuring Circumference: Measure the circumference of the arm 2 inches above the cast. If the end of the if the cast is very close to the elbow, then measure mid-bicep. Do not measure around the cast! Only measure around the skin of the arm above the cast. 

Measuring Length: Measure from the tip of the middle finger to the top end of the cast. It is okay if the cast protector measurement is longer then the limb measurement. The protector will still work. Extra length will be removed when the vacuum seal is created.
