Check whether your sofa fits through the door, straight, on its side, or tilted on the diagonal.
Delivery day is the wrong time to discover a sofa does not fit
A sofa that fits your living room can still fail at the front door, the hallway, or a tight turn on the stairs. Delivery teams see this every week: a beautiful sofa, a narrow doorway, and a long wait while everyone measures again. The frustration is avoidable, because the test takes five minutes with a tape measure and this checker, and it is far easier before the delivery van arrives.
This checker compares your sofa with your door in three ways. First, it tests the straight pass, where the sofa goes through as it stands. Second, it tests the sofa on its side or end-on, which is how most large sofas actually travel through doors. Third, it checks the tilted diagonal fit, where the sofa end is angled inside the doorway opening. If any method works, the sofa can pass that door.
How to measure the sofa
Measure the sofa at its widest, tallest, and deepest points, including arms, feet, and any part that sticks out. The width is the longest side, usually from arm to arm. The height is from the floor to the highest point, usually the back. The depth is from the front edge to the back. Do not use the showroom dimensions alone, because feet, cushions, and packaging add centimetres.
Measure the door the same way: the clear width when the door is fully open, not the width of the frame, and the clear height under the frame. If the door can come off its hinges, measure again with the door removed, because that often gains two or three centimetres. Also measure the narrowest point on the whole route, including hallways, turns, and lift doors, since the sofa must pass every obstacle, not just the front door.
A worked example
Take a sofa 200 centimetres wide, 90 high, and 95 deep, and a door 90 wide and 210 high. Straight through, it fails, because 200 is far wider than 90. On its side, the sofa end is 90 high and 95 deep, and the tilted diagonal of that end is about 131 centimetres, which fits inside the door opening when angled. The checker therefore reports that the sofa fits by the tilted method, even though it cannot go straight.
That result comes with a warning: a mathematical fit is not a guarantee. The hallway behind the door must leave room to angle the sofa, and the delivery team must be able to grip and turn it safely. Use the result as a strong yes or no for the doorway itself, then check the rest of the route before ordering.
Tricks that gain centimetres
Removing the door from its hinges is the easiest gain, often two to three centimetres of clear width. Taking the sofa legs off helps too, sometimes five centimetres of height, and most legs unscrew by hand. Removing packaging before the doorway, rather than after, also helps, because thick wrapping adds width exactly where you need it least.
If the sofa still does not fit, ask whether the back or arms come off. Many sofas ship in sections or have removable backs, and the retailer can confirm this before delivery. A sofa that arrives in two pieces solves most doorway problems, and it is worth asking about even if the checker says the whole sofa fits, because stairs and turns are often tighter than doors.
When the answer is no
A clear no is useful information, not a dead end. Check a different entrance: a back door, a patio door, or a ground-floor window may be wider than the front door. Check whether a larger door exists on the route, such as double doors into a hallway. And check the sofa size itself: a model 10 centimetres narrower may fit where the first one failed, with no visible difference in the room.
Do not force a sofa through a doorway that is clearly too small. Forcing damages door frames, walls, and the sofa itself, and it can injure the people carrying it. If the numbers say no and no trick changes them, choose a different sofa, a sectional version, or a delivery route that works.
Frequently asked questions
Does the checker cover stairs and turns? No, it tests one doorway only. Stairs, landings, and turns need their own measurements, because a sofa that passes a door can still get stuck on a bend. Measure the narrowest width and the ceiling height at each turn.
Should I measure with packaging on or off? Measure the sofa itself, then add a couple of centimetres for packaging if the delivery team will carry it wrapped. If they unwrap at the door, the sofa measurement alone is the right one.
What if my door is an arch or an unusual shape? Use the narrowest clear width and the lowest clear height. The checker assumes a rectangular opening, so the narrowest point is the limiting factor.
