Product review (5 stars): Actual size: 14 5/16 x 11 13/16 x 5/8 Perfect fit for me!!!
Size is not accurately described, but 5 stars because it fit perfectly. Another person had described the accurate measurements, and I'll post them here again:

14 5/16 x 11 13/16 x 5/8

Why there are so many sizes for these damn screens is unknown to me, but I had visited every local store in vain looking for something. I broke a screen cleaning it prior to my parents' selling their home, and I needed a replacement fast. AMAZON TO THE RESCUE!!
