A pipe bending template includes an object with four indicator marks displayed along a length thereof. The four indicator marks are spaced according to a bend radius and a bend angle of a pipe. The object may be formed from a plate, a tube, a flat screen display or a slide rule. With a plate, the indicator marks are displayed along an edge of the plate. With a tube, the indicator marks are notches cut through the tube. The tube is sized to receive an outside perimeter of the pipe. With a flat screen display, the indicator marks are displayed along an edge of the flat screen display. With a slide rule the indicator marks are arranged in different rows along a length of the slide rule. The slide rule also includes four indicator strips that are aligned with the indicator marks on the slide rule.
