More on How to Measure

Measuring Circumference Measure the circumference of the arm or leg right above the cast. If the end of the cast is very close to the elbow, then measure mid-bicep (for arm) or measure mid-thigh (for leg). Do not measure around the cast! Only measure around the skin of the arm or leg above the cast. Measuring Length Measure from the tip of the middle finger (or the bottom of the heel) to 2" above the cast. It is OK 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.
