DryPro Sizing Chart

Begin by measuring the circumference of the arm or leg, right above where the cast ends. If the cast happens to be close to the elbow or knee, measure the middle of the bicep or middle of the thigh.**Do not measure around the cast, please measure the skin**


Once you have the circumference of the arm or leg, measure from the tip of the middle finger or bottom of the heel to the top end of the cast. It's fine if the protector measurement is longer than the limb. Any extra length will be removed when the vacuum seal is created.
