An apparatus for holding portable electronic devices of different sizes is provided, including a receiving base, a first clamp unit and a second clamp unit, wherein the receiving base has a flat shape, with two opposite surfaces for receiving area and positioning area respectively. The positioning area forms a plurality of positioning sliding trenches in parallel layout. The entrances to the positioning sliding trenches are located at the edge of the receiving base. The ends away from the aforementioned edge of the positioning sliding trenches are closed. A part of the positioning sliding trenches has narrower openings than the width of the trenches. The first clamp unit and the second clamp unit include at least a positioning block respectively. The positioning blocks on the first clamp unit and the second clamp unit are inserted into positioning sliding trenches at corresponding locations. The first clamp unit and the second clamp unit extend to the two sides of the receiving area of the receiving base, facing each other. To adjust the holding width of the two clamps, the positioning blocks can be inserted to a different positioning sliding trench.
