Definitely size up....
We ordered a "P" in the "popular 24 inch" and I wish I had ordered a larger size.  For anyone that wants to make a statement on a large blank wall, definitely go much larger than 24 inches.  I'm sad, but luckily it will look nice on a much smaller wall. I do think for the amount of money paid for plywood that some sort of hanging apparatus should be included. Very pretty but an learned an expensive lesson.
