Will a couch (312x318x312 cm) fit through a 31 cm door?
Expert analysis
A couch measuring 10 ft 3 in × 10 ft 5 in × 10 ft 3 in does not fit through a door, but it's about 9 ft 4.5 in too large at the tightest point. The binding dimension is width: that is the axis where the couch runs out of room. We checked every orientation, and none places the couch fully inside. One caveat: applied practical clearance for handling (see tolerance buffer above).
