Sofa Size Finder
Free tool · No signup · Instant answer. Enter your room dimensions and we'll recommend the right sofa size — with space left for doors, radiators and real life.
How the recommendation works
- Wall space: the sofa should span no more than two-thirds of its wall, leaving room for side tables and lamps.
- Walkways: we reserve 75–90 cm of clear passage in front of and around the sofa.
- Depth allowance: we assume a typical sofa depth of 90 cm when checking the room's other dimension.
- Layout matters: corner layouts unlock corner sofas; open-plan rooms suit sofas used as dividers.
Tool FAQs
How much space should I leave around a sofa?
Leave at least 75 cm of clear walkway around the sofa (90 cm is comfortable), and allow for door swings, radiators and other furniture. This tool factors walkway space into its recommendation automatically.
What is the standard depth of a sofa?
Most UK sofas are 85–100 cm deep. Compact 2-seaters can be 75–85 cm deep; deep lounge sofas and recliners reach 100–110 cm. Always check the product's depth, not just its width.
Will the recommended sofa fit through my door?
This tool recommends a sofa width for your room, but you must separately measure your narrowest doorway (usually 76 cm in UK homes), hallways and stair turns against the sofa's packaged dimensions before ordering.
