3-Seater Sofa Dimensions and 2-Seater Sofa Size: How Many cm?

Short answer: A standard 3-seater sofa is 234-240 cm wide and a 2-seater sofa is 180 cm wide. Depth is 95-100 cm in the classic layout and goes up to 107 cm in the deep-seat modular layout; the height at the back is 72-80 cm. The inner dimensions that determine comfort are separate: seat height 42-48 cm, seat depth 55-65 cm. A 3-seater seats three people and a 2-seater seats two — the name "3-seater" describes the seating capacity, not the number of cushions.

3-seater sofa dimensions: how many cm is a three-seater sofa?

The three-seater sofa is the main piece of sets in Turkey, and its width falls into two bands:

↔ Scroll the table sideways to see all of it.

These dimensions are not estimates; they are taken from the piece lists of real Selishome models: the three-seater of the Venüs sofa set is 240 × 95 × 80 cm, the three-seater of the Virjin sofa set is 240 × 100 × 80 cm, and the modular three-seater of the Arinna sofa set is 234 × 107 × 72 cm.

The 6 cm difference in width is insignificant; the real difference is in depth. A sofa 95 cm deep seats you upright and compact, and it is easy to get up from. A sofa 107 cm deep wraps around your body and suits sitting reclined, but it needs 12 cm more space in your living room. In a narrow living room, those 12 cm can be the difference that ends the walkway in front of the coffee table.

How much of the 240 cm is actually seating?

Not all of the three-seater's 240 cm width is seating area. The two armrests take up 30-50 cm in total; this leaves 190-210 cm of net seat width, which divided among three people comes to 63-70 cm per person. So a standard three-seater sofa really seats three adults. In models with thick armrests and a 220 cm body, the net area drops to 170-180 cm; there the third person is squeezed.

2-seater sofa dimensions: how many cm is a two-seater sofa?

The width of a two-seater sofa (settee) is 180 cm. Depth and height are the same as the three-seater's, because it is a piece of the same set: 95 cm depth, 80 cm back height. The 2-seater of the Venüs set measures exactly 180 × 95 × 80 cm.

• 160 cm: A narrow two-seater for small living rooms and modular layouts. Two people sit; there is no room for a third.
• 180 cm: The standard two-seater. After deducting the armrest allowance, 140-150 cm of net seat area remains; two people sit comfortably, and a third person fits for a short time.
• 200 cm: A wide two-seater. One person can stretch out full length; in small living rooms it takes the place of a three-seater sofa.

A frequently asked question is this: can you lie down on a two-seater sofa? Because the net length between the armrests of a 180 cm body is 140-150 cm, an adult of average height cannot lie down without bending their knees. If lying down is your main use, look at a 200 cm two-seater or a layout with a chaise module.

Single armchair and accent armchair dimensions

The third piece of the set is the single armchair, and its dimensions are the ones that vary the most:

↔ Scroll the table sideways to see all of it.

The body of the accent armchair is narrower and its back is higher; because it is designed for one-person seating, it behaves differently from the single armchair that comes with a set. Detailed comparison: what is an accent armchair and how to choose one.

Will a 3+2+1 set fit in the living room? Wall length calculation

Knowing the piece dimensions is not enough; the critical question is whether the set fits in the living room. The calculation goes like this:

• 3-seater sofa 240 cm → the wall where the sofa will stand must be at least 270 cm (15 cm of breathing room on each side).
• 2-seater sofa 180 cm → at least 210 cm of wall.
• Single armchair 80-95 cm → at least 110-125 cm of wall.
• 40-45 cm between the sofa and the coffee table. This gap is both leg room and passing room; if it drops below 30 cm, reaching the coffee table while seated becomes difficult.
• 100-120 cm between two sofas facing each other. If a person needs to pass between them, 90 cm is the lower limit.

A rough check: a classic 3+2+1 set, together with armrest allowances and breathing gaps, needs a total of 6-6.5 metres of wall in the living room. If the seating area of your living room does not have this much uninterrupted wall, you need to consider the set not as three pieces but in a 3+1+1 or corner layout. For placement plans, see our article on sofa dimensions and living room layout, and for a comparison with the corner layout, our article corner sofa or sofa set.

The dimensions are right but the sofa is uncomfortable: look at the inner dimensions

Width and depth tell you whether it fits in the room; they are not the dimensions that tell you whether it is comfortable.

• Seat height 42-48 cm. This is the distance from the floor to the top surface of the cushion. At the right height, the soles of your feet rest fully on the floor and your knee stays level with your hip. Below 40 cm makes standing up difficult; above 50 cm leaves the feet dangling.
• Seat depth 55-65 cm. This is the measurement from the front edge of the cushion to the backrest; it should not be confused with the body depth. Even in a sofa with a body depth of 107 cm, the seat depth is 60-65 cm, and the rest is the thickness of the arm and backrest. At depths beyond 65 cm, the lower back of a shorter user does not touch the backrest.
• Armrest height 55-65 cm. This is the natural position of the elbow; it needs to be 15-20 cm above the seat surface.

These three dimensions are tested by sitting in the store. Fabric and filling differences are also part of comfort; we covered these topics separately in our articles how to choose sofa fabric and how to tell a quality sofa.

Will a three-seater sofa fit through the door?

A 240 cm sofa goes through a door not by its width but by its depth and height: it is tilted onto its side and brought in. So the dimensions to check are the clear opening of the door and the sofa's depth of 95-107 cm. In a standard 80-90 cm interior door opening, a classic three-seater sofa passes tilted on its side; with wide modular sofas 107 cm deep, narrow corridors and stair turns can cause problems.

Do not place an order without taking measurements: door width, the turning point in the corridor, elevator cabin depth and stairwell are four separate checkpoints. The step-by-step measurement list is in our article will furniture fit through the door and the elevator. To compare models, you can look at our sofa set category.

Frequently Asked Questions

How many cm are 3-seater sofa dimensions?

A standard three-seater sofa is 234-240 cm wide, 95-107 cm deep and 72-80 cm high at the back. After deducting the armrest allowance, 190-210 cm of net seat area remains.

How many cm are 2-seater sofa dimensions?

A standard two-seater sofa is 180 cm wide; its depth and height are the same as those of the three-seater in the same set (95 cm depth, 80 cm height). Two-seaters of 160 cm for narrow living rooms and 200 cm for wide use are also available.

How many people sit on a 3-seater sofa?

Three adults sit. On a 240 cm body, 63-70 cm of net seat width falls to each person. In models with a body under 220 cm, the third person is squeezed.

How deep should a sofa be?

Body depth is 95-100 cm in classic models and 107 cm in deep-seat modular models. The seat depth, which determines comfort, should be 55-65 cm.

How high should a sofa seat be?

42-48 cm. The test for the right dimension is simple: when you sit, the soles of your feet should rest fully on the floor, and your knee should be level with your hip or a few centimetres lower.

How much wall is needed for a three-seater sofa?

At least 270 cm. You need to leave 15 cm of breathing room on each side of the 240 cm body; without this room the sofa looks squeezed against the wall and cleaning becomes harder.
