ABSTRACT:
Construction materials such as 4-foot by 8-foot sheets of plywood, drywall, and similar materials have fiducial markings for quick visual reference of the user. Imprinted lines of equal spacings indicate to the user the location of wall studs at 16-inch or 24-inch spacings, and the sheet of material can also include oblique lines and one or more circles, for reference of the user in quickly determining the size of remnants. Similar markings may also be applied to roll-stored materials such as carpeting.
