A method and apparatus for dimensioning and, optionally, weighing an object. A platform with a surface is used for supporting an object. A user selects between two different dimensioning devices of the apparatus. The first device employs three distance sensors to determine a distance between each of the distance sensors and a side of an object. The second device includes a movable gate which is passed over and about an object or objects on the platform. Sensor arrays, such as paired, aligned light emitter and receiver arrays, are used in combination with a plurality of sensed gate positions to determine the dimensions of the objects(s) as the gate passes around the object(s) based on whether or not light from an emitter on one side of the gate reaches a light receiver on another, opposing side of the gate.

The apparatus of claim 1, wherein the platform is transparent, and the plurality of emitters comprises a plurality of light signal emitters on one of the upper arm and the lower arm and a plurality of light signal receivers on the other of the upper arm and the lower arm. 4. The apparatus of claim 3, wherein the plurality of emitters further comprises a plurality of light signal emitters on one of one side support and the opposing side support and comprises a plurality of light signal receivers on the other of the one side support and the opposing side support. 5. The apparatus of claim 1, wherein the plurality of emitters comprises a plurality of light signal emitters configured in one or more rows of equally spaced light emitters and wherein the plurality of light signal receivers is configured in one or more rows of equally spaced light receivers, an arrangement of the one or more rows of light signal receivers mirroring an arrangement of the one or more rows of light emitters. 6. The apparatus of claim 5, wherein the plurality of light signal emitters is configured in two or more rows, and wherein light signal emitters of each row of light signal emitters are longitudinally offset from light signal emitters of any adjacent row of light signal emitters. 7. The apparatus of claim 5, wherein each light signal emitter is individually operable independent from any other light signal emitter. 8. The apparatus of claim 5, wherein each light signal emitter in a common row is equally spaced at between about 3 mm and about 5 mm apart. 9. The apparatus of claim 5, wherein each row of light signal emitters is equally laterally spaced from any adjacent row of light signal emitters at between about 6 mm and about 8 mm apart. 10. The apparatus of claim 1, wherein the platform has a first straight edge and a second straight edge orthogonally adjoined with the first straight edge at a corner adjacent the common location and has a third arcuate edge opposite the corner such that the surface of the platform substantially forms a quarter circle. 11. The apparatus of claim 10, further comprising a corner stop that rises vertically from the corner of the platform, the corner stop having a first vertical surface and a second vertical surface wherein the first vertical surface is orthogonal to the second vertical surface and wherein the first vertical surface and second vertical surface are orthogonal to the surface of the platform. 12.
