ABSTRACT:
An improved measuring tape which allows both inside and outside dimensions to be read directly from the same printed face of the tape. The tape measure comprises a case having a tape coiled inside the case and extending out of the case through a slot in the case. Inside the case is a guide wheel which guides the tape along a bottom wall of the case. The front wall of the case is transparent so that the graduations on the tape can be seen adjacent to the bottom wall. A pointer on the case points to the graduations such that when the tape is fully retracted, the pointer points to a measurement corresponding to the width if the case. This enables the case and the tape to be used to make inside measurements.
