What Are The Different Mattress Sizes?

Here, we’re going to focus on each of the different mattress sizes: their names, their dimensions, and how you can find the right one for you.

Crib Mattress

Size: Approx. 27” X 52”
Fits: A baby, and not much else.
Description: Crib mattresses are standardized to fit most baby cribs. These mattresses are usually more firm, providing more support for developing bodies and reducing the risk of suffocation. Twin infants will likely each need their own mattress/crib, despite how adorable it is when they fall asleep cuddled together.

Twin Mattress

Size: Approx. 38” X 75”
Fits: Toddlers. Kids. Tweens. Teens (provided they haven't had a crazy growth spurt yet.)
Description: The perfect size for almost any kid’s room, twin mattresses are slim and unobtrusive. They’re easy to move around. They can be stacked (as in bunk beds) or placed together (as in shared rooms). A high-quality twin mattress will most likely carry a child from toddlerhood up through their teenage years... as long they don’t break the six-foot height barrier.

Twin XL Mattress

Size: Approx. 38” X 80”
Fits: Teens, College Students, And Tall Single Sleepers
Description: The twin XL offers five more inches in length over the standard twin — which doesn’t sound like a lot, unless your bed is five inches too short. Tall, single sleepers may prefer the twin XL over a standard twin for the added length, particularly when they can’t upgrade to a full or queen mattress.

Full Mattress

Size: Approx. 54” X 75”
Fits: The tallest of teens. Adults & couples who want something more economical in terms of price or space.
Description: A decent choice for a first apartment (or any living situation where floor space is at a premium), full mattresses are also a good go-to solution for guest bedrooms. Single sleepers should have more than enough space to get a full night’s rest, provided they don’t roll around too much.

Full XL Mattress

Size: Approx 54” X 80”
Fits: Tall sleepers/couples. 
Description: The full XL offers five more inches in length over the standard full — which doesn’t sound like a lot, unless your bed is five inches too short. Tall, single sleepers may prefer the full XL over a standard XL for the added length, particularly when they don’t have enough floor space to upgrade to a queen mattress.

Queen Mattress

Size: Approx 60” X 80”
Fits: Single sleepers who enjoy more space. Couples.
Description: The queen-sized mattress is perhaps the most popular, and most versatile, option available. Queen mattresses fit into most rooms and give most sleepers plenty of space to enjoy comfortable sleep. Couples who are OK sharing their sleeping space can likewise benefit from the queen size.

King Mattress

Size: Approx. 76” X 80”
Fits: Couples who appreciate their own space. Single sleepers who really appreciate their own space.
Description: This is the big one. The king mattress is the absolute dream, offering couples what essentially amounts to an entire bed’s worth of space for each sleeper. Just be aware that all of this extra space has to come from somewhere, so you’ll want to make sure that you have a room large enough to accommodate it comfortably.

California King Mattress

Size: Approx. 72” X 84”
Fits: Couples who don’t mind losing a bit of their own space to accommodate the taller person’s feet. Tall, single sleepers who really appreciate their own space.
Description: California Kings are kind of like the state of California. Bigger than most, but longer than they are wide. This gives tall sleepers more legroom so that monster under your bed doesn’t grab your hanging toes in the night. If you know, you know. Just like the regular King, you need to make sure you have the room for one of these big mattresses. So plan accordingly.

Get The Right Mattress For Your Needs

There are a lot of factors that go into choosing the right mattress, but in the end, they boil down into three simple questions: How much space do you need? How much room do you have? How much are you willing to spend?
