To provide a multiply adjustable size hanger so as to fit the thickness of subjects to be attached such as head jamb.

The multiply adjustable size hanger is composed of a support part and a hanging part. The support part is composed of a hook part and a front plate extending downward from the front end of the hook part, and the front plate is provided with a round support hole into which the hanging part is passed to support. The hanging part has a circular cross-section and has a butting part having a polygon shape on the base end. The abutment part has sides each having a different distance from the center of the hanging part. The abutment part abuts on the object to be attached from below to pinch the object to be attached in cooperation with the hook part. The butting part can be rotated to suitably select the side of the abutment part which is made to abut on the bottom face of the object to be attached so that the distance between the abutment part and the bottom face of the object to be attached can be suitably adjusted, and the hanging part can be easily adjusted in the horizontal posture.
