An image measuring apparatus includes: a mounting table on which a measurement object is placed; an image capturing unit disposed opposite the mounting table and captures an image of the measurement object; a control unit that controls the image measuring apparatus; and a memory unit that stores at least the shape of the measurement object and the measurement method corresponding to the measurement object, associated to each other. The control unit includes: a placement judging unit that judges whether or not the measurement object is placed on the mounting table in a state ready for measurement based on the image captured by the image capturing unit; and a measurement performing unit that selects a measurement method based on the shape of the measurement object appearing in the image and performs the measurement, when the placement judging unit determines that the measurement object is ready for measurement.
