Abstract:
A device for estimating the length of a floor covering needed from a roll of a floor covering having a predetermined width to cover a room including any fill area based on a scaled diagram of the room showing walls bounding the room, the device comprising:a generally planar body having an upper surface and an opposing lower surface for contacting the diagram; a first positioning guide provided on the body for aligning the body on the diagram about a first direction; a second positioning guide provided on the body for aligning the body on the diagram about a second direction; a floor covering width indicia provided on the body along the first direction; a floor covering length indicia provided on the body along the second direction; a fill width indicia provided on the body and corresponding to the first direction; and a data matrix comprising multiple cells defined by the intersection of the fill width indicia and the floor covering length indicia, with at least some of the cells containing a fill length data indicium having a value representing the length of floor covering needed for a fill area corresponding to the intersecting fill width indicium and floor covering length indicium for the cell.
