A length measuring jig can improve the whole work efficiency by more conveniently and accurately performing measurement when a large amount of objects are repetitively measured. A length measuring jig comprises a supporting board(10) having a certain length and V-shaped section to put on a measurement object(1); a scale(20) which is fixed to the supporting board and arranged in the longitudinal direction; a reference stopper(30) which is fixed to one side terminal of the bracket, and supports one end of the measurement object; a movable measurement block(40) sliding on the supporting board toward the reference stopper and adhering to the other end of the measurement object; and a display unit(50) which is fixed to the movable measurement block and passes over the scale.
