The panel cutting guide includes a primary elongated measuring rod and a pair of secondary measuring arms releasably secured thereto in spaced parallel relationship. A pair of marker elements are slidably mounted on each of the secondary measuring arms, on opposite sides of the primary measuring arm, with each marker element including a releasable locking member for securing the marker in any of a plurality of positions on its associated secondary measuring arm. The adjustability of the secondary measuring arms and the marker elements thereon enable the operator to position the marker elements at the perimeter of a wall opening, such as an electric receptacle box. With the marker elements in position, the panel cutting guide can be placed on a panel to be cut, so that the marker elements will locate the opening to be cut in the panel in order to accommodate the wall opening.
