An L-shape, or a sofa and armchairs?
If you’re asking this, you’re probably standing in the living room, torn between one big seat and seating that moves. Taste matters, but the answer sits in the room itself: how many free walls there are, where the doors are, and how many of you usually sit together.
The numbers at a glance
Start with the walls
An L-shape needs a free corner: two walls that meet, with no door, window or balcony door in the way. The long side usually runs 2.4 to 3 m, the short side about 1.5 to 2.2 m, and the depth is close to a metre.[2] Around it, keep a walkway of at least 76 cm.[1][4]
A sofa and armchairs need just one wall. An armchair can stand in front of a window, beside a door or in the middle of the room, which is what makes them easier in rooms with several doors.
Which one suits your room?
Five quick questions. The answer follows the numbers in this article.
An L-shape
- You often sit together, and an L-shape seats more people in the same corner.
- The chaise is made for stretching out.
When to choose an L-shape
- You often sit together in front of the screen. An L-shape seats more people in the same corner.
- You like to stretch out or lie down. That is what the chaise is for.
- You have a free corner and a room of about 3.7 × 3.7 m or more.[2]
When to choose a sofa and armchairs
- The room has several doors, or people walk through it to other rooms. Separate pieces leave easier paths.
- You like to talk face to face. Keep 1.2 to 2.4 m between the sofa and the armchair facing it.[3]
- You like to change the layout, or you may move home. Separate pieces are easier to move and easier to get through a door.
The Olivia L-shape
The Tando set
And the room in the picture?
The room above is 3.6 × 3.5 m, a little under 3.7 × 3.7. The L-shape fits, but the chaise takes from the space in front of the table. The sofa and armchair leave a wider walkway, and that is what we would choose for this room.
Before you order
- Chaise on the left or the right? Put it on the side away from the room’s door and the path you walk, so it doesn’t close the way in.
- Measure the way in. The front door, the lift and the turn of the stairs, and ask how many sections the L-shape comes in before you order.

Questions we hear often
Can an L-shape work in a 3 × 3.5 m room?
It will be tight. Most L-shapes have a long side of 2.4 m or more and need a 76 cm walkway around them. In that room a two-seater and an armchair give the same seating in less space.
How many armchairs go with a sofa?
In a medium room, about 3.5 × 4.5 m, one or two. In a large room, two armchairs facing the sofa. What matters is keeping 1.2 to 2.4 m between the seats.
Can I pair an L-shape with an armchair?
Yes, in larger rooms of about 4 × 5 m and up. Place the armchair facing the long side, with a walkway of at least 76 cm between them.
Will the L-shape get through the front door?
Measure the door’s width and height, the inside of the lift and the turn of the stairs. Send us those numbers with the L-shape’s name and we’ll tell you how many sections it comes in and how it gets through.
