Hmm, that is strange. It seems a little narrower and longer than it should be. A quick measure of my Nook says 3.75 x 6.25. There are probably still many 7" tablets out there with the same size screen though since they are usually sourced through a common manufacturer and there are many 7" tablets. There are universal protectors you should also have no problem with an 8" or larger protector that you can cut down.
