Expert analysis
A small bookshelf (30"×12"×48") measuring 30 in × 12 in × 72 in fits through a door, with about 1 ft 6.5 in to spare at the tightest point. The binding dimension is width: in its best-fitting orientation, the width is what comes closest to the limit, and it still clears. We checked every orientation and confirmed at least one places the small bookshelf (30"×12"×48") fully inside without compression or disassembly. That margin already subtracts a 1.5 in handling allowance, so it reflects a realistic load rather than a paper-thin theoretical fit. One caveat: applied practical clearance for handling (see tolerance buffer above).
