Seating, screens and walking room

A living room layout is three distances: seat to screen, seat to table, and the walkway that lets people cross the room without turning sideways. All three are in the facts above, measured from the drawn layout — including the 30-inch circulation path that stays clear by construction.

A typical 84-inch three-seat sofa on one long wall faces a typical 60-inch TV console on the other, with 11 ft 8 in between seat and screen.
A coffee table sits 16 in off the sofa — the commonly used reach — a typical 48 by 24 inch coffee table.
A second seat fits across the end wall: a typical 60-inch loveseat.
The far end takes a typical six-seat 72 by 36 inch dining table with 3 ft of chair room kept clear on both long sides — this is great-room territory.
