Will your sofa fit?
Check whether a sofa physically clears your doorway, hallway turn, stairwell, and elevator before you order. Failed deliveries cost the buyer $150-$400 and 6-8 weeks. Catch it upstream.

The calculator runs four independent clearance checks. The doorway check assumes the sofa enters on its side or vertically — the smallest cross-section dimension must clear the smallest door dimension. A standard 32-inch wide × 80-inch tall door comfortably accepts a sofa with a 36-inch deep × 34-inch tall cross-section when tipped.
The hallway turn is the usual failure point. Sofa length must be at most the diagonal across the 90° corner. If your hallway turns immediately after the front door, this is the first thing to measure. Same logic applies to stairwell turns and elevator interiors.
All inputs are optional except the sofa and doorway. Skip hallway, stairwell, or elevator if not on the delivery path. The verdict is conditional on what you measured — measure everything for full coverage.

Frequently asked questions
Will a 3-seat sofa fit through a standard doorway?
Most 84-inch three-seat sofas fit through a standard 32-inch doorway when carried on their side or vertically — because the sofa's depth (~36 inches) becomes the dimension that has to clear the door, and the door is taller (80 inches) than the sofa is deep. The real failure point is rarely the door itself but the 90° turn just past it.
What is the hallway-turn diagonal and how do I measure it?
It is the longest straight line your sofa can travel through a corner where two walls meet at 90°. To measure: at the corner, measure diagonally from the inside of one wall to a point on the opposite wall at the same distance — the diagonal of the largest square that fits in the corner. This number caps the sofa length that can physically pass through.
Can I get a sofa up a narrow stairwell?
Sometimes yes by tipping vertically, sometimes no. The deciding measurement is the diagonal across the stairwell turn (corner-to-opposite-ceiling). If your sofa length exceeds this diagonal and disassembly is not an option, the only remaining solution is hoisting through a window or balcony.
What if my sofa does not fit?
Four options in order: try every orientation (most sofas fit when tipped on their side), check whether legs detach, remove the door from its hinges for ~2 extra inches of clearance, or call a professional hoisting service ($200-$600 in cities). Hoist is often cheaper than the return-shipping fee.
How accurate is this calculator?
It checks the standard clearance constraints sofa deliveries usually fail at — doorway width and height, hallway corner diagonal, stairwell diagonal, elevator interior. It cannot account for awkward staircase landings, low ceiling beams, or tight elevator door openings that are narrower than the elevator interior. Always do a final tape-measure pass on the delivery path before ordering.
Does removing the door help?
Yes — removing an interior door from its hinges typically adds 1.5 to 2 inches of horizontal clearance. Standard interior doors lift off their hinges in five minutes with a screwdriver. This single trick salvages a meaningful share of borderline deliveries.
