A body height measuring apparatus including a measuring bar and ground mainframe. An operational control module and ultrasonic body height measuring module are provided in the measuring bar and the ground mainframe. The operational control module, the synchronous signal transmitting unit and the ultrasonic signal transmitting unit are provided in the measuring bar, wherein the synchronous signal transmitting unit and the ultrasonic signal transmitting unit are connected to the operational control module. The synchronous signal receiving unit, the ultrasonic signal receiving unit and the operation processing unit are installed in the ground mainframe. Since the apparatus comprises a measuring bar together with a ground mainframe, and the measured value of the body height is obtained by computing the difference in time when the two signals are transmitted from one side to another, the measuring error is reduced and the measuring accuracy is improved with good effects.
