To determine what smartCRUTCH size will fit you best you will need to know your height, your forearm circumference measured at the widest part of your forearm, and your inner forearm length measured from the crease of your wrist to the fold of your elbow, with your elbow bent at a 90° angle.
If your measurements do not correspond with a particular smartCRUTCH size, please reach out to us!
