A living room with a fireplace and TV works best when you decide what the main seats need to face. Start with the television, the fire, or two separate seating activities, then check the actual room dimensions. Putting both features in the room does not mean they have to share one wall.
The three options below are layout concepts, not fireplace installation plans. Measure your TV's outside dimensions, the hearth projection, furniture and door swings before choosing one. For screen sizes, start with our TV dimensions chart.
