ABSTRACT:
A layout square having a handle and two legs that extend away from the handle in the same direction, both perpendicular to the handle. The handle includes a level to allow angular measurements against level, as well as for plumbing and leveling purposes. The legs correspond in width to standard dimensions of construction materials to facilitate the measuring and marking of those dimensions on materials. One leg is marked along its edges with linear and angular measurement marks for measuring and marking lines and angles, and has holes disposed selectively along its length for receiving a marker, such as a carpentry pencil. The other leg is marked with angular measurement marks along its edges and has a window with pitch marks along the edges thereof to facilitate the measurement and marking of angles and pitch.
