A bedroom is only need to be 70 square feet legally. Fortunately, the typical apartment bedroom is 132 square feet, while the average house bedroom is 219 square feet. It doesn't matter what kind of housing you live in, there are only so many square feet available for other uses once you take into account the size of your bed, dresser, and other furniture. The actual amount of space that you have available for storage is called your "footprint." For example, if you have an 80-square-foot bedroom and all of the space not used by furniture is filled with boxes or racks, you have 85 percent usage of the room and need at least one more box to make it 100 percent. If you have limited storage space, consider downsizing your wardrobe. There are also legal requirements regarding bedrooms. They must be separate from other rooms (such as a living room or kitchen) and they must have a door that closes. The National Association of Home Builders says that most homeowners want a bedroom that's 70 square feet or larger. However, smaller bedrooms can be comfortable if they have their own private bathroom attached or if they are on the second floor with a ceiling height of 10 feet or higher. In conclusion, a normal-size bedroom is 70 square feet.
