Compression garments are not the same size as regular clothing because everyone's body is different, which affects the amount of pressure the garment puts on your body. Any error in these measurements can even have the opposite of the desired effect.
For specific garments such as knee braces, calf sleeves, thigh sleeves, elbow braces or wrist braces, you should measure the circumference of the joint and compare these measurements to the manufacturer's specifications to choose the correct size. Remember that this type of garment should fit snugly against the body, but without restricting blood circulation or causing pain. This determines whether the wearer should choose size S, M, L or XL.
