The critical idea here is how the belt interacts with its buckle. The tongue loop width is kept small so the buckle can grip securely and the belt stays cinched without the loop flopping or catching on the bar during a lift. Limiting the tongue loop to 5 cm ensures the buckle engages cleanly and the belt remains stable under load. Wider loops would not fit smoothly in the buckle and could compromise security, while much wider measurements are simply impractical for standard belt designs. Therefore, 5 cm is the maximum width allowed.
