A dimensional weighing apparatus is disclosed which has a weighing scale for determining the actual weight of a carton, and a conveyor means along which cartons are moved after being weighed to pass the cartons through a measuring station at which the length, width and height of the cartons are measured. A first measuring means measures both the height and length as the cartons move through the measuring station by means of a member that rides up the leading vertical face of the cartons to measure the height and then across the top surface thereof to measure the length. A second measuring means measures the width of the cartons as they move through the measuring station by means of carton contact members mounted along the side surfaces of the carton and move in and out of contact with the carton. Computer processing means receives the linear measurement data, calculates the volume, compares that volume with a predetermined threshold volume stored in a memory, and if greater calculates a dimensional weight of the carton and compares that with the actual weight as determined by the scale, and sends a signal indicative of the larger of these weights to a shipping system to determine an appropriate shipping charge.
