How do you correctly determine whether size 4 is right for me? — Umbilical Hernia Support Belt with Reinforcement, Type-353-4, Beige, 1 pc – Toros-Group

According to the card, size 4 is chosen by waist circumference of 111–120 cm; the height of the belt is 22 cm, net weight 0.215 kg. Use: use as intended, choosing the size by the waist. The card does not describe how to measure the waist or what to do on the border between sizes.

General information (not a manufacturer's instruction): the waist is usually measured with a tape measure horizontally, standing, without pulling the tape tight; if your circumference is on the border of two sizes, you have had surgery or feel discomfort, check the size with a doctor or an orthopaedic-products specialist. A belt that is too loose shifts, one that is too tight creates excessive pressure; in case of numbness, pain or skin irritation, take it off.
