A Handy Guide to Mattress Dimensions
To make your mattress shopping easier, we’ve created this handy infographic of standard mattress dimensions. Whether you’re trying to decide between a king and queen size for your master bedroom, want to upgrade your guest room, or need to find a mattress for your child, taking the size of the bed and who it’s for into account will help you settle on the perfect choice.
We put together this handy bed size chart to show you the dimensions of the different mattress sizes so you can find the right one for you.
Which bed is right for you?
Now you know the dimensions of all the mattress sizes, but how are you supposed to determine which bed size is your ideal match? Here’s what to consider before selecting a mattress size.
If you’re over 6 feet tall, then a twin or full size mattress may not be long enough to allow you to sleep comfortably. Because these mattress sizes are both only 75 inches long (which translates to 6 feet 2 inches), they may leave you with feet dangling over the bed. If this is the case, consider a twin XL mattress, which is the same width as a standard twin but 5 inches longer. Queen and king size beds, meanwhile, also offer an additional 5 inches in length over twin and full sizes. They’re also wider, making them a better option for couples or anyone who wants extra space to spread out.
One of the most important factors to consider when choosing a bed size: the size of your bedroom. For each mattress size, here are the minimum recommended bedroom dimensions for a comfortable fit:
- Twin: 7 feet by 10 feet
- Twin XL: 7 feet by 10 feet
- Full: 10 feet by 10 feet
- Queen: 10 feet by 10 feet
- King: 10 feet by 12 feet
- Cal king: 12 feet by 12 feet
You should also take your sleep position into account. If you’re a combination sleeper—someone who switches positions throughout the night—a full size bed will give you ample room to move around as a solo sleeper, while a queen or king will ensure you won’t disturb your partner.

Number of sleepers
Do you sleep alone or with a partner? Solo sleepers can do well on a full size bed (especially if your bedroom is on the smaller side), while twins and twin XLs are great options for kids and teens. Queen and king size beds are your best bet if you sleep with a partner. With a queen size bed, you get 30 inches of space per person, and with a king size bed, each of you gets 38 inches of space to yourselves.
If you and your partner have different sleep preferences, meanwhile, think about getting a split king. This setup consists of two twin XLs side by side. With a split king, each of you can choose your preferred mattress firmness.
Finally, consider your budget. Smaller mattress sizes cost less money than larger ones. For example, a full size mattress is typically 10-15% less expensive than a queen size bed.
