The sponge holder basket (bottom) itself is 7 inches wide and 2.5 inches tall. The total height of the sponge holder bottom is 4 inches. The clips are 1 inch by 1 inch and the distance between (inside) the 2 sides is 1.309 inches (the part that would clip on the center of the sink). The clips are designed to snap in and cinch tight to the slotted holes (may take a little force).
