PURPOSE: An apparatus for measuring a length of an adjustable pipe is provided to precisely and accurately measure a length of an adjustable pipe by obtaining the straightness of a wire which is drawn from a wire measuring part. CONSTITUTION: An apparatus for measuring a length of an adjustable pipe comprises a first fixing unit(100), a second fixing unit(200), and a wire measuring unit(300). The first fixing unit is composed of a first bolt part(110) and a first nut part(120). The second fixing unit is composed of a second bolt part(210) and a second nut part(220). The backend part of the wire measuring unit is combined with the first bolt part of the first fixing unit to be attachable and detachable. A wire(310), in which a loop(320) is combined at a front end of the wire measuring unit, is reeled to be drawn to a front part. The wire measuring unit fixes the loop on the second bolt part of the second fixing unit. The wire measuring unit measures a draw length of the wire through a wire draw sensor(330) by drawing out the wire.
