How it works
Most sofas go through a door on their back or side, so the key test is whether the depth or the height is less than the door's clear width. If neither is, many sofas can still be angled through when their diagonal depth (from the top of the back to the front edge of the seat, measured on the side) is less than the door width. Raymour & Flanigan advises comparing the sofa's diagonal depth with your doorways and turns.
Measure the door opening at its narrowest point, with the door open, from the stop to the edge of the open door. Remove the door from its hinges for an extra inch or so. Check hallways, turns and stairs too: this calculator checks one doorway only.
