Abstract: A dual-camera apparatus derives dimensional measurements of an object. The apparatus comprises a pair of digital cameras each comprising a lens and capable of producing an image of the object. A ratio of known distance units to pixels is established for the apparatus and applied to images generated by each of the digital cameras. The lenses are spaced apart at a first known distance. In operation, the first known distance and the established ratio provide a trigonometric basis for ascertaining distances between at least two features on the object. A calibration template can be used to establish the ratio of known distance units to pixels. The object can be a human subject, and the at least two features can be associated with the human subject's eyes, the human subject's feet, and/or other human body parts. The disclosure also relates to a method in aiding in lens selection.
