Abstract: An auxological measuring apparatus in which there is provided a flat surface which is preferably horizontal, having on it a plate arranged for contact by the feet of a person with his back against the surface and on the case of a horizontal surface lying supine on it, there being a carriage linearly moveable on the surface which can be brought into contact with the person's head. An electronic transducer is associated with the carriage and is arranged to produce an electric signal indicative of the distance between the carriage and the surface and it is associated with electronic circuitry arranged to process the signal and to provide a visible indication of the distance and thus of the height of the person on the surface. A side table may be provided for attachment to the surface so that a person may lie on the surface and the side table with arms outstretched on the table so that an arm span mesurement can be made.
