Will a couch (218x100x102 cm) fit through an 81 cm door?
Expert analysis
A couch measuring 7 ft 2 in × 3 ft 3 in × 3 ft 4 in does not fit through a door, but it's about 9 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).
