What is the maximum number of persons that a sofa can accommodate? When purchasing a couch, this is a crucial consideration. Of course, the size of the sofa varies depending on whether it’s for children or adults, but there are standard proportions for sofas that seat 2, 3, 4, or 5 people.

We’ve included a series of tables and images below that show you the right couch measurements based on the number of people you’ll be seating.
