Abstract
Self measuring roll goods includes a pliable substrate, a front surface, and a rear surface. The rear surface includes fiducial markings to facilitate the quick and easy measurement of the roll goods. The fiducial markings include an array of symbols, and at least a portion of the peripheral edges of the symbols are spaced apart from the peripheral edges of adjacent symbols. The pitch of the array defines a gross measurement scale. In a particular embodiment, the peripheral edges of the symbols intersect tangentially. In another particular embodiment, the symbols are completely spaced apart. Examples of the symbols include closed curves, polygons, and linear symbols. Optionally, marks on the perimeters of the symbols and/or the vertices of the symbols provide a fine measurement scale.
