If your lack of sleep is affecting your day-to-day activities, it might be time to upgrade your bed to a larger size or a higher quality. Below, you'll learn everything you need to know with a bed size fact sheet.

  • King

    Traditional king-size beds measure 76 inches wide by 80 inches long. California king-size beds measure 72 inches wide by 84 inches long. Sharing a king-size bed with another person affords one the same room as sleeping alone in a twin-size bed.

  • Queen

    Queen-size beds measure 60 inches wide by 80 inches long. Olympic and California queen-size beds are sometimes difficult to find, it is even more difficult to find linens for them. The Olympic queen measures 66 inches by 80 inches, and the California queen measures 60 inches by 84 inches.

  • Full

    The dimensions of full-size beds are 54 inches wide by 75 inches long. They are sometimes called double beds. Before king and queen sizes existed, most couples slept on full-size beds. These beds are ideal for pre-teens or teens who are shorter than 65 inches.

  • Twin

    Standard twin beds, also known as singles, hold mattresses that measure 39 inches wide by 75 inches long. Extra-long twins are 5 inches longer. Small children will fit this size of bed perfectly, but twin beds can accommodate adults, as well.

  • Toddler

    Toddler beds hold mattresses that are the same size as crib mattresses, give or take about one-half an inch. They usually measure 27 inches wide by 52 inches long. The small size makes it easy to place waterproof pads or sheets on top of them, which will come in handy if your toddler is working on potty training.

  • Bunk

    Bunk beds come in two configurations: twin-over-twin or twin-over-full size. If you have multiple children, bunk beds may be the ideal sleeping arrangement for them. Though 165 pounds is a standard weight limit for bunk beds, it is best to check the manufacturer's guidelines prior to purchase.
