    Abstract: A child height measuring and data recording device comprises generally planar rigid panels having transverse pins at their ends for snapping into slots in connectors which articulate the sections for folding and unfolding. One panel is fastened to a wall and the others may be folded over it when not in use or unfolded to hang along the wall during making measurements and recording data. The front faces of the respective panels have parallel coextensive data channels. One channel has means for retaining photographs and the other has English and metric linear scales for measuring height. A hinged and captured connector is used for constraining the panels in folded condition.
