Abstract: An expandable garment hanger assembly has a central frame and housing assembly. An arm pair assembly with a right and left side arm portion is pivotally coupled to an interior portion of the frame and housing assembly and designed to be folded or laterally extended. The right and left side arm portions are rotatably engaged to move rotationally and simultaneously in the opposite direction. A release spring and lock assembly is disposed within the frame and housing assembly and designed to be locked when the arm pair assembly is closed. At least one depressible release assembly is coupled to the spring and lock assembly designed to release the spring and lock assembly to extend the right and left side arm portions. A right and left side arm extender portion is slidably coupled to the distal ends of the right and left side arms respectively and designed to extend or retract.
