Work out furniture fit in room instantly with clear inputs, formula shown and shareable results.
Fitting furniture is as much about circulation as about the piece itself. A main walkway needs 75-90 cm, a secondary route 60 cm, and 30-45 cm between a sofa and a coffee table. Checking the remaining walkway rather than just the wall length is what prevents a cramped room.
Furniture fit
remaining wall = room length - furniture length; walkway = room width - furniture depth
75-90 cm for a main route, 60 cm minimum for a secondary one, 90 cm behind a dining chair, and 30-45 cm from sofa to coffee table.
Measure the narrowest doorway, the stair turn diagonal and any low ceiling. Many sofas fit the room but not the route to it.
