How to Measure
Measure your wrist circumference at the narrowest part of the wrist that is above the wrist bone. (C)
Measure your elbow circumference at the fullest part of the elbow (E)
Measure your upper arm circumference at the part just below the armpit.
Determine your length (C-G) by measuring from the wrist to the part of the arm where the armpit starts.
If your arm does not fit within all the sizes listed for a single garment, you may need a custom arm sleeve. Talk to your therapist or doctor.
