Mattress Size Guide

We’ve got your back…whether you sleep on your back, side, or head to toe with your partner. Here are some tools to help you find the right mattress for you.

How They Stack Up


While a Twin bed is commonly used for children, single sleepers of any age can get quality rest on this mattress. Its compact design is perfect for small spaces or studio apartments. But if you’re someone who likes to sprawl out while sleeping, you may need to adjust your snoozing position — or opt for something bigger.


The Twin XL is the same width as a twin, but it’s 5 inches longer, making it the same length as a standard Queen or King. So if you’re fine with a Twin otherwise but just looking for a little legroom, it’s a good bet. Some parents decide to go with a Twin XL for their kids so they don’t have to rebuy if their kids become supertall; also, many college dorms have Twin XL bed frames.


Also known as a double, the Full mattress is 15 inches wider than a Twin, making it a comfortable choice for an apartment upgrade, a guest room, or individuals who want more room to sprawl out than a Twin allows for (but don’t have the space for a Queen). Sharing this mattress is possible, but fair warning: you or your partner might get nudged off the bed if one of you tends to toss and turn at night.


The Queen mattress is the most popular bed size among adult sleepers. It’s 6 inches wider and 5 inches longer than a Full bed, providing ample space without taking up too much square footage. Whether you sleep alone or with a partner or furry friend, a Queen will have your back.


If your bed doubles as an office or you highly value your personal sleeping space, a King mattress is the right choice. While requiring a more spacious bedroom, the King bed’s additional 14 inches in width over the Queen gives couples plenty of room to sleep soundly without intruding on each other’s territory. There’s even enough space for the kids to jump in for movie night or breakfast in bed.


The Cal King (short for “California King”) is similar in overall size to a King, but it’s 4 inches narrower and 4 inches longer. There are a few reasons why some prefer it to a standard King: If you have a narrower bedroom but still want a King, this is a good alternative so you can have a large bed but still be able to walk easily around it. Also, tall people often prefer it for its extra length. If you sleep with a partner, though, you’ll have a bit less personal space than on a King (but still more than on a Queen).
