Perhaps the most common bed in North American homes. At roughly 152 centimeters wide and 202 centimeters long, it offers balanced proportions for two people sleeping together. Each occupant receives about 76 centimeters of personal width, which works well for average-sized bodies but feels snugger for larger frames. The length accommodates taller individuals comfortably. Many first apartments and starter homes default to this size for its versatility and widespread availability of bedding accessories.
