Details before you move
It is flat-packed in a box about 43.9 by 6.42 by 14.29 inches at roughly 54 lb, then assembled in the room. Assembled, the bookcase stands about 71 inches tall and 25 inches wide — but only the flat box has to pass through your door.
Easily. At only about 6 inches thick and 14 inches wide, the flat box clears any standard 30- to 36-inch door without tilting. Even a tight 28-inch opening is comfortable for the box's short faces.
The assembled 71-inch height never has to go through a standard door, because you build the bookcase after carrying the flat box in. If you must move it pre-assembled, the 71-inch height is the limit and you would tilt it to clear a typical 80-inch door frame.
