For the neatest look, your belt should be worn at the third hole. The belt size is the length in centimetres, measured from the third hole at the end and excluding the buckle. You measure your waist at the lowest place, wherever you wear your belt. The number of centimetres in circumference is ultimately the size you need. Below you can find which waist length in centimetres fits which belt size.
