The door label is not the space the furniture can use.
A nominal door size can include parts of the frame that are never clear during delivery. This checker uses the narrowest measured gap between the fully open door and the opposite stop, plus the lowest measured point across the opening. It then compares that opening with a simplified rigid furniture frame after genuinely removable height is deducted.
The model tests whether the furniture can be turned so its narrower depth-or-frame-height side passes through a rectangular opening. That is more useful than comparing furniture width with door width, but it is still a screen. It does not model the approach angle, a short hallway, a second doorway, packaging, flexible upholstery, or a complex three-dimensional pivot.
Worked example
A sofa frame approaching an 81 cm clear doorway
A sofa is 220 cm wide, 96 cm deep, and 82 cm high. Twelve centimetre legs are confirmed removable. The open doorway measures 81 cm wide by 203 cm high at its tightest points.
Rigid frame after leg removal
220 x 96 x 70 cm
Clear opening
81 x 203 cm
Narrow frame side
70 cm
How RoomFact reads it
The simplified screen leaves 11 cm of width margin and enough opening height for the 96 cm opposing side. It passes this doorway check, but the 220 cm length and the turning space on both sides remain untested.
Only subtract a component when the retailer confirms it can be removed without altering the frame or warranty.
Measure the open door itself. A handle, closer, hinge, stop, security bar, or thick mat may define the true narrow point.
The result should be sent with approach photographs and measurements to the delivery company before the return window closes.
01
Find the real bottleneck
Open the door to the position it will hold during delivery and measure at several heights. Check from the exterior approach through the frame and into the next space. The smallest usable width is the input, even when most of the opening is wider. Repeat the process for every entrance, vestibule, hallway pinch point, and destination door.
Measure the furniture at its rigid extremes rather than across compressed cushions. Record the full length because a long item may clear the opening yet have no space to rotate before or after it. Product packaging can be larger than the assembled piece, so obtain both packaged and unpackaged dimensions when delivery policy allows either condition.
02
Treat a positive result as evidence, not approval
A small positive margin can disappear through measurement error, protective blankets, trim variation, or an opening that is not square. RoomFact uses a caution state when the simplified width margin is under 5 cm, but no margin is a universal guarantee. A delivery team may require more space or reject a maneuver that risks injury or damage.
Make a short delivery brief with the product link, rigid dimensions, removable parts, opening dimensions, and photographs taken square to the route. Ask the retailer or carrier to confirm the plan in writing. Their assessment, building rules, and conditions on delivery day take priority over this browser calculation.
