A tool is used simultaneously align and square a conventional mat cutter. The tool is an elongated member (such as a rectangular block) with a bottom surface and at least two perpendicular lateral edges, together with a channel extending across its bottom surface parallel to one of the lateral edges of the tool. The vertical cross-section of the channel is contoured to seat firmly against the guide rail assembly of the mat cutter. Using the guide rail assembly as a fixed point of reference, the perpendicular arms of the mat cutter can be aligned and squared against the lateral edges of the tool. In addition, the tool can be used to ensure correct placement of measuring rulers on the perpendicular arms of the mat cutter.
