Does a 3-seat sofa fit in a 3x4 m living room?

It fits along the 4 m wall, but it eats the walkway: a 2.28 m sofa leaves under 50 cm of route on the door side. A 1.6 m two-seater keeps the room usable; add an armchair if you need the extra seat.

How big a TV works at this distance?

The sofa sits about 2.9 m from the screen. At 2.5-3 times the diagonal, that's comfortable for a 47-55 inch TV.

Why this layout works

01The sofa backs onto the short wall farthest from the door, so the room opens up the moment you walk in.
02TV and sofa face each other across 2.9 m, right in the comfortable range for a 55-inch screen.
03The bookshelf uses the long wall's dead end, where a walkway would never fit anyway.
04One corner lamp instead of side tables keeps the floor visually clear; small rooms read bigger with fewer legs on the ground.

Clearances to keep

Rules of thumb this layout respects. Full dimensions guide

45 cm between the sofa and the coffee table: close enough to reach a cup, far enough to cross your legs.
A 60 cm walkway from the door to the window stays clear along the east side.
The door swings inward across 90 cm; nothing stands inside its arc.
