Bookcases are 12–16" deep and fit through any standard door. The challenge is height (72–84") and hallway maneuvering, not the door.
Whether it fits comes down to the measurements most people skip.
Real openings run about 1 to 2 inches under the labeled size, and a single inch can flip the result. Check your own measurements before you buy or move.

Frequently asked
