The invention is a method and apparatus for measuring the dimensions of a parcel for use in a parcel processing application. The invention includes the placing of a parcel on a weighing scale. A movably mounted emitter apparatus projects lines of a known distance apart onto the parcel so that the number of lines may be counted by a scanner to determine a first linear dimension of the placed parcel. After the first count is performed, the emitter apparatus is rotated in place 90- so as to project a second set of lines on the first surface of the placed parcel. The second set of lines is then counted so as to determine a second linear dimension of the placed parcel. After the second count is performed, the emitter apparatus is moved so as to project a third set of lines on a second surface of the parcel, wherein the second surface is perpendicular to the first surface. The third set of lines is counted to determine the third linear dimension of the placed parcel. Counts one, two, and three are transmitted to a data processing device which applies the counts to a look-up table to determine a set of linear dimensions for the placed parcel. The linear dimensions and the weight are transmitted to the parcel processing application for further use within that system.
