L-Shaped Sofa Dimensions: Corner Sofa Size in cm and m²
Short answer: L-shaped sofa (corner sofa) dimensions are not a single figure. The usual range: long wing 230-340 cm, short wing 230-330 cm, depth 100-120 cm, body height 72-90 cm. A compact L-shaped set takes up about 232 × 235 cm, while a wide modular L-shaped set reaches 340 × 330 cm. Because an L-shaped sofa is built from modules, the size is not fixed — you find it by adding up the widths of the corner module, the armrest module and the middle module.
L-shaped sofa dimensions: a table from real models
The figures below are not estimates; they are calculated from the parts lists of the corner sets at Selishome. The wing length is measured from the outer edge of the corner module to the end of that wing — so the corner module is included in both wings.
| Model | Long wing | Short wing | Depth | Body height |
|---|---|---|---|---|
| Aura Corner Set | 235 cm | 232 cm | 107-118 cm | 77 cm |
| Petra Corner Set | 238 cm | 232 cm | 107-116 cm | 78 cm |
| Kays Corner Sofa Set | 330 cm | 240 cm | 100-120 cm | 90 cm |
| Tesla Corner Sofa | 330 cm | 310 cm | 100-110 cm | 83 cm |
| Arinna Corner Sofa | 340 cm | 315 cm | 107 cm | 72 cm |

The table clearly shows two bands: compact L-shaped sets with 232-240 cm wings and wide L-shaped sets with 310-340 cm wings. The 100 cm between them alone decides which wall of the living room can take what. A compact L sits with breathing room on a 350 cm wall; for a wide L, that wall needs to be at least 370-380 cm.
Size comes from the modules: corner, armrest, middle
The size of a classic 3+2+1 set is fixed; that of an L-shaped sofa is not. This is because an L-shaped sofa is built from modules placed side by side, and each module has its own width. The real module widths are as follows:
- Corner module: a square body 110-120 cm wide and the same in depth. It is 110 × 110 cm on the Tesla, 116 × 116 cm on the Petra, 118 × 118 cm on the Aura and 120 × 120 cm on the Kays.
- Armrest module: the piece at the end of the wing, with an armrest. It varies between 114-132 cm.
- Middle module: a seat without armrests. It is 80-90 cm; it is added in between to lengthen the wing.
- Side table / music module: a slim connecting unit 35-40 cm wide. It does not add a seat but lengthens the wing by 40 cm.
- Sofa bed and lounger modules: they reach 170-200 cm in width and the depth can go up to 180 cm.
You make your own calculation like this: wing length = corner module + the widths of the other modules on that wing. For example, on the Tesla Corner Sofa one wing is 110 cm corner + 200 cm sofa bed module = 310 cm; the other wing comes to 110 + 100 + 80 + 40 = 330 cm. We also explained the logic of the modular layout in should you buy modules or a set.
What do right-hand and left-hand mean?
This is where most mistakes are made when ordering an L-shaped sofa. The rule is simple: when you look at the sofa from the front, if the long wing is on the right it is right-hand, if it is on the left it is left-hand. In some productions the description is the other way round, based on looking from sitting on the sofa; so when ordering, confirm the direction not in words but by drawing a sketch of the room.
On modular sets the direction can usually be changed later too; because the modules are independent of each other, the order can be taken apart and rebuilt. On corner sofas with a fixed body, however, the direction is permanent — if the corner of the living room turns out to be the opposite way when you move, the sofa will not fit.
How many m² does an L-shaped sofa take up?
An L-shaped sofa occupies an L-shaped footprint, not a rectangular one; the calculation is the sum of two rectangles. The real floor area of a set measuring 310 × 330 cm with a depth of 100 cm is 310 × 100 + 230 × 100 = 5.4 m². But the space you set aside in the living room is larger than this:
| Set size | Sofa footprint | Including walkway in front |
|---|---|---|
| 232 × 235 cm (compact) | 3.8 m² | about 7 m² |
| 310 × 330 cm (wide) | 5.4 m² | about 9.5 m² |
| 340 × 315 cm (wide, low body) | 5.9 m² | about 10 m² |
↔ Scroll the table sideways to see all of it.
For the walkway, leave at least 80 cm in front of the sofa and 40-45 cm between the coffee table and the sofa. A gap of 5-10 cm between the wall and the sofa is also good; with no gap the sofa looks squeezed against the wall and the skirting board pushes the body forward.

Depth and inner dimensions: the numbers that decide comfort
The outer dimensions tell you whether the sofa fits in the living room; the inner dimensions tell you whether it is comfortable. The inner dimensions to look at on an L-shaped sofa:
- Seat height 42-48 cm: when you sit, the soles of your feet should rest fully on the floor.
- Seat depth 55-65 cm: on modular sets with a body depth of 107 cm, the seat depth increases; it suits stretching out, but you need a back cushion to sit upright.
- Body depth 100-120 cm: the corner module is 10-15 cm deeper than the other modules because it has a square body. Calculate the wall allowance according to the deepest module.
We gave the corresponding dimensions of classic three-seater and two-seater sofas in 3-seater and 2-seater sofa dimensions. We built the decision between an L-shaped sofa and a classic set step by step in corner sofa or sofa set.
The measurements fit but the sofa would not go in
The most frequent problem with an L-shaped sofa concerns not the living room but the way in. A 200 cm sofa bed module or a large 120 × 170 cm armrest module will not fit in a lift; it has to turn on the stair landing. This risk is low with modular sets because each module is carried separately. Before ordering, measure the lift cabin, the door width and the turning allowance on the landing — details in will furniture pass through the door and the lift. You can see the models with their dimensions in the corner sofa category, and for a module list, for example, look at the Tesla Corner Sofa Set or Arinna Corner Sofa page.
Frequently Asked Questions
What are the dimensions of an L-shaped sofa in cm?
Wing lengths are 230-340 cm, depth 100-120 cm and body height 72-90 cm. Compact sets take up around 232 × 235 cm, wide modular sets around 340 × 330 cm.
How long does the wall need to be for a corner sofa?
Add 10-20 cm of breathing room to the wing length. For a 232 cm wing you need 250 cm of free wall, for a 330 cm wing 350 cm. If there is a socket, radiator or door on the wall, increase this allowance.
How many cm is the corner module of an L-shaped sofa?
It is 110-120 cm wide and the same in depth. Real examples: 110 × 110, 116 × 116, 118 × 118 and 120 × 120 cm.
How many people does an L-shaped sofa seat?
It depends on the wing length. If you allow 60-70 cm of net seat per person, a 232 cm wing seats 3 and a 330 cm wing seats 4-5. The person sitting on the corner module uses both wings, so counts as one.
What does a right-hand corner sofa mean?
It means the long wing is on the right when you look at the sofa from the front. Because the description can be reversed from one manufacturer to another, sharing a sketch of the room with the order is the safest way.
Will an L-shaped sofa fit in a small living room?
It will, but the wing length should not exceed 240 cm and the set should be placed in a corner rather than along a single wall. In living rooms under 20 m², wide modular sets block the walkway.
Can the size of an L-shaped sofa be extended later?
On modular sets, yes: by adding a middle module or a side table module, the wing can be lengthened by 40-90 cm. On corner sofas with a fixed body, the size does not change.
