Twin vs. Queen: What’s the Difference?

Size matters—particularly when you’re shopping for a new mattress. Twin mattresses and queen beds are both popular mattress sizes, but for very different reasons.

One—the twin bed—is ideal for very small bedrooms and primarily used in kids’ rooms, while the other—the queen size mattress—is a great option for couples and those with larger bedrooms.

Is a twin size mattress or a queen size mattress right for you? Our twin bed vs. queen guide will help you determine just that.

Twin mattress size

A twin mattress (also known as a single bed) measures 38 x 75 inches. A twin mattress size is considerably narrower than a full size mattress, which measures 54 x 75 inches. It’s also shorter than a twin XL mattress, which measures 38 x 80 inches.

Pros of a twin

When would a twin mattress make more sense than a queen size bed? Here are the top four reasons to choose a twin vs. queen:

  • A twin mattress is great for growing children. It’s an ideal size between toddler beds and the full-size mattress they may use as teenagers. It also fits nicely into kids’ rooms. “Twin beds are so fantastic for kids’ rooms because you don’t need much space for them,” says Prudence Bailey, founder and principal designer of Prudence Home + Design in Connecticut. “They can function as a bed or even a day bed.”
  • Bailey adds that having two twin mattresses in a room is perfect for kids who love throwing sleepovers—or siblings who share a bedroom.
  • A twin mattress size is versatile—it can be used in bunk beds, day beds, and for solo sleepers in studio apartments. (Keep in mind, your bedroom should be 7 feet by 10 feet at minimum to fit a twin size mattress.)
  • Since a twin mattress is the smallest mattress size, it naturally comes with the smallest price tag and it’s a piece of cake to move.

Cons of a twin

Of course, a twin mattress isn’t without its drawbacks. Here are the biggest downsides to this mattress size:

  • It’s too small for two. Given that a twin mattress is only 38 inches in width total, it doesn’t afford much space for two people. A queen size bed, which measures 60 x 80 inches, is the ideal mattress size for couples because each sleeper gets about 30 inches of space to themselves.
  • Because it’s only 75 inches long (which translates to 6 feet 2 inches), a twin size mattress may not be long enough for taller teens or adults. If you’re over 6 feet tall, or you suspect your teen will grow, a twin XL might be a better option because it offers an additional 5 inches in length.“Twin beds feel small for most adults, so they are a much better option for children,” says Bailey.

Queen mattress size

At 60 by 80 inches, a queen is not as large as a king size bed (which measures 76 x 80 inches), but it’s still pretty roomy.

Pros of a queen

A queen size bed has a lot of things going for it. Here are the top three reasons you should choose one over a twin size bed:

  • It’s versatile, making it an outstanding option for couples and solo sleepers alike. Each sleeper gets about 30 inches of space to themselves. This gives couples plenty of room to move around. If you’re a combination sleeper—someone who switches positions throughout the night—you should have enough room in a queen size bed so you won’t disturb your partner.
  • You’ll have enough room for kids and pets as well. Although a queen size mattress isn’t quite as large as a king, you should still comfortably be able to snuggle with your family.
  • There’s more legroom than a twin size bed. Because queen size beds are longer than twin size beds, they’re a better option for tall sleepers. Remember: A queen size bed is 80 inches long (roughly 6 feet 8 inches), while a twin size bed is 75 inches long, which is barely more than 6 feet in length.

Cons of a queen

To be honest, there aren’t a ton of drawbacks when it comes to a queen size bed, but here are a couple of points to consider before buying one:

  • Naturally, a queen size bed doesn’t offer as much room for couples and/or families as a king size bed. You’ll have 8 inches less width in a queen size bed than you would in a king.
  • If you have a very small bedroom, a queen size bed is still sizeable enough to cramp your space. You should only choose a queen size mattress if your bedroom is at minimum 10 feet by 10 feet.
