Question: what is the average size of a living room in a house?
Answer: Medium living room A space of 12 x 18 ft (about 3.7 x 5.5m) would fit between 6 and 10 people in a conversation area with about 5 of the seats facing the TV (TV would be better placed in a corner on the fireplace wall than above the fireplace). There's room for 3-seater sofas in medium sized living rooms.
