I bought the bandage, since I have a tendonitis. To determine the size I kept strictly to the specified dimensions. Unfortunately, the thumb hole is so tight even with the largest size that within a very short time to sleep the thumb or hurts. That's why I miusste the bandage in two sizes each return. Apart from the bandage made a high-quality and comfortable impression. Maybe other buyers have anatomically better luck, in my case it was unfortunately completely useless. In female hands I could imagine that it fits better.
I have at the ankle a wrist circumference of 17.5 cm and had ordered the size L / XL.
