How do you choose the size of this belt? — Universal anti-hernia inguinal bandage 351-3

The card has no size chart or waist-circumference range; the name says “universal” and no size range is given. According to the Russian description, the belt is worn around the waist and fastened at the back with a textile fastener, and the choice takes into account the material, the length of the strap, the degree of fixation and the pressure force. The card does not specify how to measure the waist or how long the strap is.

General information (not a manufacturer's instruction): the waist is usually measured with a tape measure horizontally, standing; the product should fit snugly but without constricting. If you are on the border between sizes, have a hernia or have had an operation, it is better to check the suitable option with a doctor or an orthopaedic-products specialist.
