A suspension-type height measuring device comprises a main measuring unit and a movable right-angled rule, in both of which there include a housing, a measuring tape reel and a control key for stopping of the tape. The device can be stuck and hung above at any location on a wall and after having been reset to zero enables a user to read out the figure of his height directly from the window by just pulling down the movable right-angled rule therebeneath to the top of the head. Alternatively, a user can read out the figure from the counter or from the electronic display by the series of small holes of same pitch provided on the measuring tape to turn a pin wheel which in turn drives a cluster system of gear or a high precision variable resistance and finally by the figure being shown on the display through a mechanical or electrical transfer.
