To measure your room for a small corner sofa, record the length and width of the wall space the sofa will occupy, subtract at least 60cm for a walkway, then check that the sofa can physically reach the room by measuring your doorways, hallway width and any stairwell turns. Those three numbers, footprint, clearance and access route, decide whether a sofa fits long before style does.
Here is the full process, broken into five steps you can complete in about twenty minutes with a tape measure, a pencil and a sheet of paper.
Start with the two walls that will form the corner. Measure each one from skirting to skirting at floor level, not at eye level, because skirting boards, radiator pipes and plug sockets all reduce the usable width.
Write down both figures. Then note anything that interrupts those walls: a radiator, a chimney breast, a door that swings inwards, a window sill that sits below sofa back height. A small corner sofa typically measures between 200cm and 240cm along its longest side and between 140cm and 180cm on the return, so compare those numbers against your wall measurements straight away.
One detail people miss: a sofa back that sits higher than a window sill or a radiator will block both. Measure the height from the floor to the bottom of your window and to the top of your radiator, and compare it with the back height of any sofa you are considering.
Numbers on paper are hard to judge. Masking tape on the floor is not.
Using your intended sofa dimensions, tape the outline of the sofa onto the carpet or floorboards, including the depth of both sections. Standard seat depth ranges from about 85cm to 100cm, and compact designs sit at the lower end of that.
Live with the outline for a day. Walk the route from the door to the window, open the cupboards, pull out the dining chairs. This is the quickest way to discover that a sofa which fits on paper still makes the room unusable in practice.
If you have a footstool or ottoman in mind, tape that too. It is easy to plan the sofa perfectly and forget the extra 60cm a footstool needs in front of it.
Fitting a sofa is only half the task. The gaps around it determine whether the room feels comfortable or cramped.
Use these working figures. Allow a minimum of 60cm for any main walkway, and 75cm where two people regularly pass. Between the sofa and a coffee table, leave 35cm to 45cm: close enough to reach, far enough to walk through. In front of a TV, aim for a viewing distance of roughly 1.5 to 2.5 times the screen width, which in most British living rooms means the sofa sits between two and three metres from the screen.
Allow clearance for doors as well. An internal door needs around 80cm of swing space, and a sofa arm parked in that arc will stop the door opening fully.
If the numbers do not work, the fix is usually a slimmer coffee table or a nest of tables rather than a smaller sofa. Our nest of tables UK sale range is useful here, since the smaller pieces tuck away when the room is busy.
This is the step that causes the most problems, and it happens entirely outside the living room.
Measure, in order: the width and height of your front door or communal entrance, the narrowest point of the hallway, the width of any internal doorway the sofa must pass through, and the headroom and turning space at any stair landing. Note whether doors can be removed from their hinges, which often buys an extra 4cm or 5cm.
For flats, measure the lift interior including the diagonal, and check whether the lift door opening is narrower than the car itself. If the stairs are the only option, measure the turn at each landing, since that turning circle, not the stair width, is usually what defeats a large sofa.
Compare these figures against the packaged dimensions of the sofa, not the assembled ones. Corner sofas are often delivered in two or three sections, which makes access far easier, and modular designs can be carried in piece by piece. If access is tight, prioritise sofas that arrive in separate parts.
When you browse our modern corner sofas UK sale collection, check the listed dimensions carefully, and note that measurements are usually given as width by depth by height.
A corner sofa is either left hand facing or right hand facing, and choosing the wrong orientation is the most common ordering mistake we see.
Use this method. Stand in the room looking at where the sofa will go, as if you were about to sit down. If the long chaise section extends to your left, you need a left hand facing sofa. If it extends to your right, you need a right hand facing one. Some retailers describe orientation from the seated position instead, so always check the wording on the product page before ordering.
Think about which side makes sense for the room rather than which looks better in a photograph. The chaise should sit away from the main entrance so nobody has to climb over it, and it should not block a radiator or a window if you can avoid it.
Where you cannot decide, a universal or modular design solves the problem. Many fabric corner sofas can be configured either way, which is worth considering if you might move house. Our corner fabric sofas UK range includes several designs with reversible chaise sections.
Measuring at the widest point of the sofa is essential, and that point is often the arms rather than the base. Flared arms and scatter back cushions can add 10cm or more to a listed footprint, so read the dimensions rather than estimating from an image.
Another frequent error is forgetting the recline. Any sofa with a reclining action needs clearance behind it, sometimes as much as 20cm, unless it is specifically designed as a wall hugger.
Finally, remember that carpet and underlay raise the floor by a centimetre or two. That rarely affects a sofa, but it matters if you are sliding one under a low window sill or beside a radiator.
Rooms rarely stay exactly as planned on delivery day, so build a little tolerance into your figures. A Christmas tree, a clothes airer, a travel cot or a folding desk all need somewhere to go, and in a small room that somewhere is usually the space beside the sofa.
Think about seasonal furniture too. Many British households bring in extra dining chairs a few times a year, and a corner sofa that fills every centimetre leaves nowhere to put them. Leaving 10cm to 15cm of slack against your tightest measurement costs very little in comfort and saves rearranging the room each time something changes.
It is also worth checking where the sockets sit. A sofa back pushed against the only double socket on that wall means running an extension lead across the floor, which is both untidy and avoidable if you spot it at the measuring stage.
Once you have five sets of figures, wall space, footprint, clearances, access route and orientation, choosing becomes straightforward. Take the smallest constraint and treat it as your ceiling, then shortlist only sofas that fall beneath it.
For genuinely small rooms, look at designs with slim arms, raised legs and shallow seat depths. Raised legs in particular make a sofa look lighter, because you can see the floor continuing beneath it, and that visual trick is worth more than a few centimetres of actual size. Pairing the sofa with a compact footstool from our foot stools UK sale range adds flexible seating without permanently occupying floor space.

Generally anything under about 240cm on its longest side, with a return of 180cm or less. Seat depth of around 85cm also keeps the footprint compact.
Allow at least 60cm for walkways, 35cm to 45cm between the sofa and a coffee table, and enough swing space for any door that opens into the room.
Choose a design delivered in separate sections, or a modular sofa. Removing internal doors from their hinges also gains a few centimetres at no cost.
Stand facing the space where the sofa will sit. If the long chaise runs to your left, you need left hand facing. Check the retailer’s wording, as some describe it from the seated view.
Often yes, provided you choose a compact model and place the chaise along the shorter wall. Taping the footprint on the floor first will confirm whether the walkways still function.
