An apparatus for measuring height, of the suspended type, comprises a main measurement assembly 1 and a moving triangle (right-angled) rule 13, both including a housing, a roll of measuring tape 2 and a control key 8 for locking the tape. The apparatus can be placed and suspended above any location on a wall, and after having been reset, it allows a user to read the indication of its height directly on the window, just by pulling downwards the triangle rule 13 situated below, at the top of the head. As a variant, a user can read the indication given by the counter or by the electronic display, through a series of small holes spaced with a certain pitch, provided on the measuring tape, so as to be able to turn a sprocket wheel which in turn drives a system with gear wheels or a high-precision variable resistor and the indication being finally displayed on the screen by mechanical or electrical transfer. <IMAGE>
