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.

Twin Bed Dimensions Guide

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 as they don’t break the six-foot height barrier.

Twin XL Mattress Size Guide

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 don't have the space to upgrade to a full or queen mattress.

Full Bed Size Guide

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.

Queen Mattress Bed Size Guide

Size: Approx 60” X 80”
Fits: Single sleepers who enjoy more space. Couples who don't mind cuddling but need just enough space to call their own when they want.
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 Guide

Size: Approx. 76” X 80”
Fits: Couples who appreciate their own space or who have children or fur babies that like to sneak into the bed in the middle of the night. 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.
