A holder for variable-sized image recording mediums is provided. The holder includes a first outer frame member, a second outer frame member, a third outer frame member, a fourth outer frame member, at least one first rail and at least one second rail. The first outer frame member is symmetrical to the second outer frame member, and each of which has a groove formed in one side thereof along a longitudinal dimension and opposite to each other. The third outer frame member is symmetrical to the fourth outer frame member, and each of which has a groove formed in one side thereof along a longitudinal dimension and opposite to each other. The horizontal level of the groove of the first outer frame member is different from that of the groove of the third outer frame member. The first rail and second rail are positioned in the area enclosed by the outer frame members. The first rail is movably inserted in the grooves of the third and fourth outer frame members. The second rail is movably inserted in the grooves of the first and second outer frame members. A holder with variable-sized enclosures is thus obtained.
