4. What are the actual dimensions of the unit?
The tall bookcases are 16 inches wide and 79.5 inches high
The wall shelf is 47 wide x 14 high
Because I mounted the wall shelf offset relative to the bookcases and added 2 inch molding I ended up with the total final outer dimensions of: 87 inches tall (in the center) x 79 inches wide
The entire unit is 11 inches deep
The section in the center is 47 inches wide x 72 inches tall
