Choose a TwoStick frame size 1" longer than your print is wide. For an 18"x24" poster with a vertical orientation, order a 19" TwoStick.
Price includes both sticks of a TwoStick frame. The frame hangs like most picture frames on a nail with the simple attached sawtooth hanger. There is no need for the twine hanger of similar frames and the "craft project" look that goes with it.
