You’ve found the sofa you want. Now comes the part nobody tells you about: working out whether it will actually fit.
Too many people buy a sofa without measuring properly, only to find it won’t get through the front door, or it fills the room completely and leaves no space to move. This guide walks you through exactly how to measure your living room for a sofa — so you get it right first time.
Step 1: Measure Your Room
Start with the room itself. You need three measurements:
- Length and width of the room — measure wall to wall at floor level
- Distance from the sofa position to the TV or focal point — you want at least 2-2.5 metres between sofa and TV for comfortable viewing
- Distance from sofa to other furniture — leave at least 45cm of walkway around the sofa
Write these down. Then work out where the sofa will sit — against a wall, floating in the middle, or in a corner.
Step 2: Measure the Sofa Space
Once you know where the sofa will go, measure that specific space. This is the maximum footprint your sofa can occupy.
For a straight sofa: measure the width of the wall or space available. Leave 5-10cm gap from each wall for the sofa to sit comfortably without touching.
For a corner sofa: measure both sides of the corner. A typical L-shaped corner sofa needs roughly 250-270cm on the long side and 150-180cm on the short side. Measure your corner before you fall in love with a specific model.
Step 3: Check the Access Route
This is the one people always forget. A sofa that fits beautifully in your living room is useless if it can’t get there.
Measure every obstacle between the delivery van and the final position:
- Front door width — standard UK front door is 76-80cm wide. Most sofas are deeper than this, so they need to be tilted or turned on their side
- Hallway width — measure the narrowest point, including any radiators or architraves that stick out
- Stairwell — if the sofa needs to go upstairs, measure the height of the stairwell and the turning radius at the top
- Door frames — measure height and width of every door the sofa passes through
The golden rule: the sofa height and depth both need to be smaller than the narrowest doorway it passes through, OR the sofa needs to be able to tilt to fit. If in doubt, contact us and we’ll advise before you buy.
Step 4: Understand Sofa Dimensions
When looking at sofa dimensions, you’ll see three measurements:
- Width (W) — how wide the sofa is from left arm to right arm. This is the measurement most people focus on.
- Depth (D) — how far the sofa comes out from the wall. Deep sofas (90cm+) are more comfortable but take up more floor space.
- Height (H) — how tall the sofa is from floor to top of back cushions. Important for access and for proportion in the room.
For corner sofas, you’ll also see the chaise depth — how deep the extended section is — and the internal seating area width.
Step 5: The 2/3 Rule
A good rule of thumb: your sofa should take up roughly two-thirds of the wall it sits against. A sofa that’s too small floats awkwardly. A sofa that’s too wide feels cramped. Two-thirds gives the right visual balance.
For example, if your wall is 400cm wide, aim for a sofa between 240-280cm wide.
