How to Choose the Right Corner Sofa Size for Your Living Room

Buying a corner sofa is one of the biggest decisions you’ll make for your living room — get the size wrong and it will either dwarf the room or look lost in it. This guide walks you through exactly how to measure your space and choose the right configuration.

Step 1: Measure Your Room First

Before you look at any sofa, measure your living room wall-to-wall. You’ll need to know the exact length of both walls where the sofa will sit. As a general rule, you want at least 30–40cm of clearance between the sofa and any other furniture or wall to allow comfortable movement around the room.

Step 2: Understand Corner Sofa Dimensions

Most corner sofas are described by two measurements — the length of the long side and the length of the short side. Our standard corner sofas at Simple Living UK measure 260cm × 260cm, which suits most medium to large living rooms. Our Chesterfield range has a slightly deeper profile at 95cm total depth.

Step 3: Left-Hand or Right-Hand Chaise?

Stand at the entrance to your living room looking in. If the chaise (the longer part) should be on your left, you need a left-hand facing sofa. If it should be on your right, you need right-hand facing. This is one of the most common ordering mistakes — our bespoke service lets you specify this at checkout.

Step 4: Consider Traffic Flow

Make sure there’s a clear walkway of at least 60–80cm between the sofa and your TV unit or fireplace. People need to be able to move through the room comfortably without squeezing past furniture.

Step 5: Think About the Doorways

Measure your hallway and doorways before ordering. A 260cm sofa arrives in sections, so individual pieces typically need to fit through a standard 80cm doorway. If you have a narrow hallway or tight staircase, let us know and we can advise on delivery logistics.

Our Recommendation

For a living room up to 4m × 4m, our Vegas or Madrid corner sofas at 260cm × 260cm are the perfect fit. For larger rooms or open-plan living spaces, our U-shape Belgravia or Cinema sofas give you the full wrap-around experience.
