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 remodelling 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 4.8 by 4.8 m (16 by 16 foot. 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 hHomes

Dimensions Guide states that living rooms in small homes are also square and are 3.6 by 3.6 m (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, 5.4 m (18 feet) long and 3.9 m (13 feet) wide. Though this would seem to be barely larger than the living room in a small home, consider that 1.8 m (6 feet) is enough room to fit an extra sofa; such a room could hold two more sofas than a 3.6 by 3.6 m (12 by 12 foot) living room.


If you don't entertain many guests, or if your family and guests socialise 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 3 by 3.3 m (10 by 11 feet) and build a large kitchen.
