To measure your room for a 3+2 sofa set, record the length and width of the room, mark every door, window, radiator and socket, choose a layout, then compare the width, depth and height of both sofas against the space with clear walkways of around 75 to 90cm. Finish by marking the sofas out on the floor with masking tape and measuring every door, hallway and staircase on the route into the room. The nine steps below walk through the process in order, so nothing is overlooked.
A three seater and two seater together make a generous amount of seating, and they need careful planning to sit comfortably in a typical UK living room. A few minutes with a tape measure now saves the frustration of a sofa that blocks a door, crowds a fireplace or simply will not fit up the stairs.
You need very little: a metal tape measure at least five metres long, a notebook or sheet of squared paper, a pencil, and a roll of masking tape or painter’s tape. A second person makes measuring long walls much easier and reduces the chance of errors. Your phone camera is useful too, for photographing awkward corners or radiators you want to remember.
Measure in centimetres throughout. Sofa dimensions are almost always listed in centimetres, and working in one unit avoids conversion mistakes.
Draw a rough outline of the room from above. It does not need to be to scale at this stage, but it should show the shape clearly, including chimney breasts, alcoves and bay windows.
Measure the length of each wall at floor level and write the figures on your sketch. Then measure the full length and width of the room across the middle. In older homes, walls are not always square, so measuring both ends of the room can reveal small differences that matter when space is tight.
These fixed features decide where furniture can and cannot go. For each one, note its position along the wall and its width.
Add any other obstacles too, such as a fireplace hearth, built in cupboards or a low beam.
With the room mapped, decide how the two sofas will sit. The three most common arrangements for a 3+2 set are:
Identify the focal point, such as a fireplace, window or television, and plan for the main sofa to face it. Pencil the sofas onto your sketch in each arrangement to see which leaves the best flow.
For each sofa you are considering, write down three measurements: overall width from arm to arm, overall depth from the front of the seat to the back, and overall height. If the sofa reclines, also note the depth when fully reclined, as this can add considerably to the footprint.
Three seaters vary widely in width depending on arm style, so compare several designs. Browsing 3 seater fabric sofas UK alongside modern 2 seater leather sofas UK is a useful way to see how different arm styles and depths affect overall size, even if you end up choosing a matching set.
Furniture that technically fits can still make a room awkward if there is no space around it. Use these guides when placing the sofas on your plan:
Remember the space you need for other furniture too. A coffee table, side tables, a television unit and any storage all take up floor area. When choosing the table, scale it to the seating: coffee tables UK come in a wide range of sizes, and a table roughly two thirds the length of the three seater usually looks balanced.
This is the step many people skip, and it is the most revealing. Using masking tape, outline the footprint of both sofas on the floor in your chosen positions. Add the coffee table too.
Leave the tape in place for a day or two and live with it. Walk through the room as you normally would, open doors, carry a tray from the kitchen and sit where the sofas will be. You will quickly notice if a walkway feels tight or if the arrangement blocks the view from the doorway. Adjusting tape is far easier than moving a sofa.
A sofa must travel from the street to its final position, and this is where many deliveries go wrong. Measure the width and height of every doorway on the route, including the front door, internal doors and any porch. Measure hallway widths and note any tight corners or turns.
Stairs need particular attention. Measure the width of the staircase, the height from the stairs to the ceiling at the tightest point and any turns or landings. For flats, check communal doors and lift dimensions.
Compare these figures with the sofa’s depth and height, since sofas are usually carried on their side or tilted through doorways. Removable legs and feet can make a useful difference. If the route looks tight, a set with slimmer proportions or a sofa that arrives in sections is worth considering.
Before committing, run through your notes once more. Check that both sofas fit the walls you have chosen with the clearances you planned. Confirm the reclined depth if relevant. Make sure the route into the room accommodates the largest piece. Finally, look at the height of the sofa backs against any windows or artwork.
When everything lines up, you can choose with confidence. Our fabric sofa sets UK sale collection lists full dimensions for each piece, which makes comparing your measurements straightforward.
Once you have finished, copy your figures into a single, tidy list. Note the room dimensions, each wall length, the position of every door, window and radiator, and the narrowest point on the access route. Keep this list on your phone so it is to hand when you are browsing or visiting a showroom.
It helps to photograph your sketch alongside the room itself, so you can remember exactly which alcove or window each figure refers to. If you later decide to add a coffee table, side tables or a television unit, you can check them against the same notes without measuring again. A clear record is also useful when furnishing other rooms, since hallway and staircase measurements apply to every large piece you bring into the home.
A few errors come up again and again. Measuring the room but not the access route is the most frequent. Forgetting the swing of a door is another, as is overlooking skirting boards and radiators, which reduce usable wall length. Some people also measure only the seat width rather than the full width including arms.
Finally, avoid rounding measurements down. If a wall is 312cm, write 312cm, not 3 metres. Small differences add up when two sofas share a room.
Measuring carefully turns choosing a 3+2 sofa set from guesswork into a clear decision. With your sketch, clearances and access measurements in hand, you can focus on style and comfort knowing the set will fit. You can explore sofa sets in fabric and leather at Furniture in Fashion, where each product page includes the dimensions you need.
It depends on the sofa sizes and layout, but you need enough wall length for each sofa plus walkways of around 75 to 90cm. Mark the footprint on the floor with tape to see how it feels in your room.
Always use the overall width, including the arms. This is the measurement that determines whether the sofa fits against a wall or between features.
Check whether the legs or feet can be removed, as this can reduce the height when tilted. Measuring the access route before choosing helps avoid the problem entirely.
