Will the sofa fit through the door and the elevator? How to measure the way in
By Lucy Home. Published 14/11/2026, updated 14/11/2026.
To find out whether a sofa will fit through the door and the elevator, measure the narrowest opening on every stretch of the way in, from the building entrance to the living room, and compare it with three sofa measurements: width, height and diagonal depth. If the sofa’s width is smaller than the opening, it goes straight in; if not, it can go in on its end, as long as the diagonal depth is smaller than the width of the door. I do this math with a tape measure in my hand before we ever talk about color and fabric, because it is the one part of the purchase you cannot fix afterwards.
A sofa with wide modules in the showroom: a module is a smaller piece, and a smaller piece gets through doors and elevators more easily.
Which sofa measurements matter?
Pottery Barn’s measuring guide works with the dimensions of the piece and one rule for each:
| Sofa measurement | What it decides | The source’s rule |
|---|---|---|
| Width (arm to arm) | Whether the sofa goes straight in, lying the way it will sit in the room | Must be smaller than the opening it passes through |
| Diagonal depth | Whether the sofa goes in standing on its end | Must be smaller than the width of the door |
| Back height | Applies to a piece without arms, such as a corner module | Must be smaller than the width of the door |
Diagonal depth is the measurement almost nobody asks for and the one that solves the most. It is not on the tag: ask the store team to measure it on the model you chose.
How do I measure the front door?
The same source says to measure the interior height and width of every doorway, staircase, elevator and hallway the piece will pass through, and to watch for architectural details and low-hanging fixtures along the way. In practice:
- Measure inside the frame, with the door open, not wall to wall.
- Write down the clear height and the clear width.
- Measure the space beyond the door too. The measuring guide published by Costco lists, next to the width of each doorway, the clearance to the opposite wall: that is what tells you whether the sofa can turn once it is inside.
What about the elevator?
For buildings with an elevator, the Costco guide asks for three measurements: the interior height of the cab, the door opening and the distance to the opposite wall. I add one of my own, the depth of the cab, because a sofa usually rides up standing on its end.
Talk to your building before delivery day. These are the questions I bring:
- Is there a service elevator? Is it bigger than the main one?
- Are there set days and hours for deliveries and moves?
- Do I need to book the elevator or let the front desk know?
And if there are stairs?
For stairs, the Costco guide lists the width of the staircase, the ceiling height above the steps and, if the stairs curve, the width at the corner and the clearance to the opposite wall. The turn is where things get stuck: a sofa that goes up a straight flight may not make it around the landing. If your way in includes stairs, send the measurements and a photo of the landing to the team before you close the purchase.
Is a modular sofa easier to get in?
It is, and that is good news for apartments. Most Lucy Home sofas are delivered in modules; only a few models arrive in one piece, and not all of those. With modules, the number you compare with the door is the size of each piece, not of the assembled sofa. The K-18 and the Otto, for example, are modular sofas. Check with the team how your model arrives and how big each piece is.
What should I write down before visiting the showroom?
- Clear width and height of the building’s front door and of your apartment door.
- Interior height, door opening and depth of the elevator cab.
- Width of the hallway and the clearance beyond each door.
- Width of the stairs, ceiling height above the steps and the turn, if there is one.
- Low-hanging light fixtures, corners and doors that swing into the path.
- A photo of every tight spot.
With that in hand, choosing the size gets simpler. The sofa size guide shows how to measure the wall and mark the outline on the floor with painter’s tape, and the guide on chaise or corner sofas helps you decide on the shape.
Bring your measurements and we will check them together
At Lucy Home, at Av. Presidente Kennedy, 3870, Aviação, Praia Grande, the sofas are set up so you can see their real size, and delivery and assembly are included in the price. If you live in São Paulo or along the Baixada Santista coast, you can schedule the delivery date. Message us on WhatsApp, send the measurements and photos of your way in, and the team will check with you whether the model fits. You can also browse the store’s sofas.
Frequently asked questions
How do I know if a sofa will fit through the door?
Measure the clear width and height of the doorway, inside the frame, and compare them with the sofa. According to Pottery Barn's measuring guide, the sofa goes straight in if its width is smaller than the opening; if not, it can go in on its end as long as its diagonal depth is smaller than the width of the door.
What is the diagonal depth of a sofa?
It is the measurement that tells you whether the sofa can pass through an opening standing up or tilted. Pottery Barn says it helps determine whether a piece can be brought in on its end, and that it must be smaller than the door width. For a piece without arms, the same source says to compare the back height with the door width.
What should I measure in the elevator?
The interior height of the cab, the door opening and the distance to the opposite wall, according to the measuring guide published by Costco. I also write down the depth of the cab and ask the building whether there is a service elevator and a set time for deliveries.
Is a modular sofa easier to get in?
Yes, because each module is a smaller piece. Most Lucy Home sofas are delivered in modules; only a few models arrive in one piece, and not all of those. Send the measurements of your way in on WhatsApp so the team can check the model you chose.
