The layout tool includes an elongated rail for placement against the plate, and a first stud marking guide extending perpendicularly from the elongated rail. The first stud marking guide has left and right side edges, and width between the side edges corresponding to the nominal thickness of the studs. A separate stud marking guide extends perpendicularly from the elongated rail. The second stud marking guide likewise has left and right side edges and a width between the side edges corresponding to the nominal thickness of the studs. The left edge of the second stud marking guide is spaced from the left edge of the first stud marking guide a distance equal to the predetermined stud spacing. A primary starter marking indication is provided on the elongated rail intermediate the first and second stud marking guides. The primary starter marking indication is spaced from the second stud marking guide a distance equal to one-half the nominal thickness of the studs.Other References
