The invention provides a length adjustable pole display system. The pole display system includes a display unit for displaying information, a base placed on a floor, and a pole unit connecting between the display having an upper end attached to the display unit, a lower pole having a lower end attached to the base and an adjustment member meshed with an outer surface of the lower pole into which a lower end of the upper pole is inserted. The adjustment member tightens an upper inner surface of the lower pole against a lower outer surface of the upper pole when locked. The poll connecting between the display unit and the base can be adjusted in length freely and simply to flexibly vary the whole length of the pole display system, thereby improving user convenience.
