California King Beds
If you’ve tried sleeping on a king-size bed, but find that your feet hang off the end, a California king mattress might work better for you. California king-size mattresses measure 72 inches wide by 84 inches long, making them less wide and slightly smaller overall than traditional king mattresses, but the 4 extra inches of length make them ideal for anyone over 6 feet tall. Any bedroom larger than 10 feet wide by 12 feet long should comfortably hold a California King bed.
Traditional king-size beds are built to hold mattresses that measure 76 inches wide by 80 inches long. King mattresses are the widest mattresses commonly sold on the market and they’re also the largest when measured in square inches. This luxurious size can afford two people nearly the same amount of space as two twin mattresses would. If you’ve been sharing a queen or full bed with your partner and need more space to sleep comfortably, consider upgrading to the king of all bed sizes. To hold a king size bed, your room should be around 12 feet long by 10 feet wide at the very least.
The most popular mattress size in the United States, queen-size mattresses measure 60 inches wide by 80 inches long. Their size enables them to accommodate couples while also fitting into smaller bedrooms than king-size beds require. If you’re living in a small urban apartment and looking for a bed you can share with your partner, then a queen-size bed might be exactly what you need. You generally wouldn’t want to put a queen mattress in a room that is smaller than 10 feet square.
Sometimes called double mattresses, full-size mattresses measure 54 inches wide by 75 inches long. Though full-size beds can be shared, most couples find them too small for their needs. They are ideal for single adults and teenagers who have outgrown twin-size beds. These versatile mattresses can also be used to furnish a small guest bedroom. The minimum recommended bedroom size for a full/double bed is 9 feet by 10 feet.
Twin XL Beds
Perfect for tall teenagers who need the length of an adult bed without the width, twin XL mattresses measure 39 inches wide by 80 inches long. This makes them five inches longer than traditional twin mattresses. Twin XL beds are most often used in college dorms, but they can also help young adults sleep comfortably in studio apartments without taking up too much space. A room that is at least 8 feet wide by 10 feet long will comfortably fit a twin XL bed.
Standard twin mattresses measure 39 inches wide by 75 inches long. They are sometimes called single mattesses. They work best for children and teenagers, but they can also provide an average-size adult with enough space to sleep comfortably. Two twin mattresses laid side-by-side are roughly the same size as a king-size bed, and some couples use this method to get king-size comfort. Any room that measures at least 8 feet by 10 feet will work for a twin bed.
Bunk beds commonly come in two size configurations: twin-over-twin and twin-over-full. Twin-over-twin bunks stack two twin-sized mattresses on top of each other while a twin-over-full bunk uses a full-size mattress on bottom instead of a twin-size. If you have multiple children, bunk beds may be the ideal sleeping arrangement for them. The standard weight limit for bunk beds is 165 pounds, but you should always check the manufacturer’s guidelines prior to purchase.
At 27 inches wide by 52 inches long, toddler mattresses are ideal for babies and small children. These mattresses are usually used for cribs, and their small size makes them perfect for placing alongside an adult’s bed. Most children outgrow these beds by age four and will require a twin-size replacement. If you are putting your toddler’s bed beside your own, be sure there is at least 30 inches between the two beds for movement.
Murphy beds are designed to conveniently fold up against the walls they’re attached to when they’re not in use. This space-saving feature is why Murphy beds are sometimes called “wall beds.” Murphy beds come in several different sizes, including twin, full, queen, and king. If you live in a small home or apartment, but you need a large bed to be comfortable, a Murphy bed is a great way to get the bed you want without crowding your small space.
Bed Sizes FAQ
What is the biggest bed bize?
At 76 inches wide by 80 inches long, king-size beds are the largest beds made for mass retail. California king mattresses are slightly narrower than standard kings, but they’re also four inches longer. If you’re over 6 feet tall and looking for a bed that is especially long, then a California king mattress might work better for you than a traditional king size.
Which bed size is right for my room?
You typically want to leave a minimum of 30 inches on all sides of your bed so you can move around it comfortably. This handy rule of thumb can help you determine if your bedroom is large enough for the bed you want.
Can a full-size bed fit two adults?
While some couples find full-size beds sufficient for their needs, full mattresses are designed to accommodate solitary sleepers. For two people living in a small apartment, a full-size bed may do the trick, but a queen-size bed is a much better option if you have the room for one.
Is a double mattress the same as a full?
Yes, full-size mattresses are sometimes called double mattresses. A mattress of either name will measure 54 inches wide by 75 inches long.
How high off the ground should my mattress be?
On average, the ideal bed height is roughly 25 inches off the ground. This height works for most adults, but it can vary depending on the thickness of your mattress, the style of your bed, and your personal needs. Antique beds can be as high as 36 inches off the ground for taller individuals. Platform beds on the other hand are usually about 18 inches high, making them perfect for children.
