A square tool with tape measure includes a triangular housing with flat opposite sides and three edges forming a right-angled corner and two acute-angled corners. A groove is arranged along an entire length of each of the edges to enable the tool to be easily grasped and lifted. A measuring tape arranged within the housing is retractable flush into one of the corners. The tape is lockable in any extended position with a locking tab recessed into one of the edges. A bubble level is arranged within a window on the housing for indicating the horizontal position. A pencil holder is attached to one of the edges for holding a pencil. A pencil sharpener is provided for sharpening the pencil. A pair of guide rails arranged along opposite sides of one of the edges can be used for aligning the tool with a work piece. The tool may be clipped to a user's clothing with a belt clip attached to a side of the housing. In alternative embodiments, the belt clip is retractable and extendable. The sides of the housing each include a textured surface on which erasable notes can be written with the pencil. The tool may be used for drawing a very large circle by extending the measuring tape, positioning a pencil at the end of the tape, and pivoting it about a nail positioned through a hole in one of the corners and into a work piece.
