What is the average size of a bedroom in most houses?

In most houses, the average bedroom size is anywhere from 120 to 150 sq. ft., with the average bedroom being 132 sq. ft. This is equivalent to the size of 10 × 12 or 11 × 12 feet. It provides enough space to accommodate a queen-size bed along with bedside tables and some wardrobe space without feeling cramped. The actual size may vary depending on the kind of house and the intended use of the room.
