In one aspect, a cuboidal container measurement system for cuboidal box dimension measurement with a transmitter (Tx) unit and a receiver (Rx) unit comprises a Tx unit with a barcode reader system that reads a bar code on the cuboidal box, a Tx infrared communication system that communicates with infrared signals to an Rx infrared communication system in the Rx unit and receives a set of cuboidal measurements made by the Rx unit from the Rx unit and receives a signal from the Rx unit that the Rx unit has been placed on a first edge of a cuboidal box, a Tx proximity sensor that detects when the Tx unit is placed on a first edge of the cuboidal box, a first laser rangefinder system that emits a laser to the Rx unit when the Tx unit is placed on a second edge of the cuboidal box, wherein the first laser rangefinder system measures a distance between the Tx unit and the Rx unit.
