Twin, full, queen and king will be the standard bed sizes from the U.S., but there are also variations on these sizes, for example extra-long twin and California king. There are also specialty beds that come in standard sizes, such as toddler and toddler beds.
A normal twin bed is 39 inches wide and 75 inches long, whereas an extra-long double sided, or double XL, is 80 inches long. Regardless of the title, a twin bed is designed for one person. Twin beds are generally used in children’s rooms. A standard full bed, also sometimes referred to as a double sided, measures 54 inches wide by 75 inches long. A complete bed can comfortably accommodate two children however, might be too narrow for 2 adults that need their very own sleeping area because every person gets only over 27 inches of space. A queen bed is 60 inches wide and 80 inches long, which makes it wide enough for 2 average-size adults and long enough for taller individuals. A typical king bed, also sometimes called an eastern king, measures 76 inches wide and 80 inches long, while a California king is 72 inches wide and 84 inches long. Both dimensions of king bed offer plenty of individual sleeping area for 2 adults, while the California king has additional length for those over 6 feet tall.
