The invention relates to a calibrating gauge for calibrating a Vernier caliper. According to the invention, the gauge has at least one calibrating face for calibrating a measuring surface for internal measurement, at least one calibrating face for calibrating a measuring surface for external measurement (3) and at least one calibrating face for calibrating a measuring surface for depth measurement (4), the calibrating gauge (1) being in the shape of an least partly hollow cylinder, on the generated surface (6) of which is provided the calibrating face for calibrating the measuring surface for the external measurement and on the inner surface (10) of which is provided the calibrating face for calibrating the measuring surface for the internal measurement, and the calibrating face for calibrating the measuring surface for the depth measurement being provided on at least one of the end faces (5) of the cylinder.
