Disclosed is a length adjustable armrest, which can customize a physical characteristic or taste of a passenger and freely adjust a forward and backward length of an armrest installed at a side part of a seat. The length adjustable armrest includes: a lower cover which is fixed at a side part of a seat; and an upper cover which is installed to be movable forward and backward with respect to the lower cover through a sliding unit. The sliding unit comprises: a base which is installed in the lower cover and has a first ratchet-type tooth-shaped portion in a lengthwise direction; a housing which is installed in the upper cover and is coupled to be movable with respect to the baes in a lengthwise direction; a rotation ratchet which is hinge-coupled to the housing and has a second ratchet-type tooth-shaped portion that can be tooth-engaged with the first ratchet-type tooth-shaped portion of the base; a spring which is installed between the housing and the rotation ratchet and enables maintenance of the tooth-engagement between the first ratchet-type tooth-shaped portion of the base and the second ratchet-type tooth-shaped portion of the rotation ratchet; and a fixing clip which is installed in the housing and restricts a movement of the rotation ratchet to convert the tooth-engagement between the first ratchet-type tooth-shaped portion of the base and the second ratchet-type tooth-shaped portion of the rotation ratchet into a disengaged state.
