A tool guiding measuring apparatus or apparatus for measuring a portion of a workpiece and guiding a tool during an operation on the workpiece. The apparatus includes an aligning body portion for positioning the apparatus in a desired orientation against a workpiece. Two tapes are provided on the aligning body portion for measuring the dimension of a portion of the workpiece. A selectively positionable clamp on a free end of the tape is used to calibrate the apparatus to provide a true measure on the tape of the dimension of the workpiece while compensating for the dimensions of the apparatus and tool. The selectively positionable clamp securely attaches to each of the tapes at a desired calibration position on the respective tape to provide ease of use and repeatable measuring. The apparatus also includes a clamping device which clamps the apparatus to the workpiece to prevent movement of the apparatus while cutting.
