Bedrooms are rooms in residential buildings furnished as spaces for people to sleep. Sized proportionally in relation to a variety of standard bed sizes, bedrooms are typically desired to be individual rooms that provide a degree of privacy to their users. Bedrooms are required to have a window for light and ventilation and are typically required to provide a closet and egress to be legally considered a bedroom. Bedrooms are often decorated to reflect the personality of the user or the household. Ranging from small dormitory bedrooms to large bedrooms with attached bathrooms, commonly called master bedrooms, bedroom layouts are adaptable to many design demands.
