A ruler for measuring shape comprises a measuring frame, an inset frame, two metal plates, another measuring frame and a plurality of sliding rods. The measuring frame has an upper flap and a lower flap integrating with the upper and lower edges of an end flap to define a slot and an open end portion. An elongated slot is formed at the mid-section of the end flap for permitting an inset slab being secured thereto. The upper and lower flaps have two mortise recesses and two screw holes respectively formed on their edges opposite from the end flap. The inset frame has two mortise recesses corresponding to the mortise recesses of the upper and lower flaps and two screw holes. Two metal plates which are of an identical size for the insertion to the mortise recesses of the upper and lower flaps and of the inset frame have two screw holes formed thereon respectively for the connection of the measuring frame and the inset frame. A plurality of sliding rods have two butts formed at both ends thereof for making contact with an object to be measured, a rod body having a horizontally extended rectangular slot for the inset slab being disposed therewithin.
