The Average Dimensions of a Living Room


Next to the kitchen, the living room may be the room in your home where you spend the most quality time with your family. Whether you're building a new home or remodeling an old one, ensure that your living room is large enough to comfortably accommodate everyone in your household.

National Average

  • As of 2011, Dimensions Guide estimates that the average living room is a 16-by-16-foot square. Depending on the size of your home --- including the number of people in your household --- it may make sense for your living room to be a different size or shape.

Small Homes

  • Dimensions Guide states that living rooms in small homes are also square and are 12-by-12 feet. You may find it practical to keep your living room to this size if there are only two people in your household, or if you live alone.

Large Homes

  • Large homes, on average, have large, rectangular living rooms, 18 feet long and 13 feet wide. Though this would seem to be barely larger than the living room in a small home, consider that 6 feet is enough room to fit an extra couch; such a room could hold two more couches than a 12-by-12-foot living room.


  • If you don't entertain many guests, or if your family and guests socialize mainly in another room --- such as the kitchen --- you may not need a large living room. For instance, you could build the living room in your small home to be 10-by-11 feet and build a large kitchen.
