On this basis, a living room/space of approximately 7.6 × 6.1m (46.36m2) appears to be optimal. This is based on a "master" couch that is typically 2.4 x 0.9m in size and two auxiliary sofas that are roughly 2 x 0.9m in size. A family of four would need about 200 square feet of living space. The actual amount of floor space that you need depends on how much furniture you have and what kind of furniture it is. For example, if you like to spend most of your time in front of the TV then you will need more space than someone who goes out once a week for dinner and drinks. In general, an average-sized living room needs to be about 15% larger than the number of people who will use it. So if you have a family of four, you should have 17.6 m2 of living space. If you only have one child then you can probably get by with less than this. As your family grows or changes, you may want to expand your living room or replace old pieces of furniture with new ones that offer additional storage space or make the room look nicer. The main thing is to make sure that you find a balance between enough space and not too much space.
