Why to Consider Sizing Up Your Mattress 

Deciding on a mattress size seems like a no-brainer. But if you recently moved into a larger space, if you’re downsizing, or if your family has recently expanded, it might be time to change your mattress size.

If you have the room, why not go bigger?

Measure the Space Around Your Bed 

Measuring the space around your bed is important—you need the space to move around! We recommend aiming to leave 2 feet of space on either side of your bed because otherwise, you may only have enough room to shuffle sideways to get to your side of the bed. Even worse, your shins may end up chronically bruised because you constantly bump into your bedframe. 

Plus, with enough space, you won’t have to cram in the essentials like a nightstand, dresser, or a comfy chair!

When you’re measuring for a bigger mattress, remember to leave about 2 feet of space on each side. This way, you and your partner can each have your own nightstand and enough room to get out of bed without disturbing each other.

Mattress Size Guide 

There are five standard mattress sizes: California king, king, queen, full, and twin. Both twin and full have “XL” sizes, which add 5 inches to the overall length. Here’s a quick rundown of the mattress size you need according to the size of your room.

Mattress Size Mattress Dimensions Room Size Recommendations (min. – max.)
 
California King 72” x 84” 12’ x 12 - 14’ x 12’
King 76” x 80” 10’ x 12’ - 13’ x 13’
Queen 60” x 80” 10’ x 10 - 10’ x 14’
Full XL 54” x 80” 9.6’ x 10.6’ - 10’ x 12’
Full  54” x 75” 9.6’ x 10.6’ - 10’ x 12’
Twin XL 39” x 80” 7’ x 10’ - 10’ x 10’
Twin 39” x 75” 7’ x 10’ - 10’ x 10’

King/Cal King  

A California king mattress size measures 72 x 84 inches, which is about 4 inches longer than your standard king size. A Cal king is ideal for people who are 6 feet 5 inches tall and for couples or families who need extra sleeping space. The minimum space you need to still have room around the bed is 12 x 12 feet.

King size mattresses are 76 x 80 inches and are also ideal for the whole brood to sleep in comfortably. At the minimum, king mattresses will fit rooms that are 10 x 12 feet. However, if you need to fit in more bedroom furniture, a room with 13 x 13 feet is best.

Queen

Queen mattresses are 60 x 80 inches, which makes them ideal for singles to starfish or couples on a budget (or in a studio or loft apartment). For the most comfortable space, 10 x 10 feet fits a queen mattress best and still leaves enough room for your bedroom furniture.

Full/Double  

Full or double size mattresses measure 54 x 75 inches and are most comfortable for single sleepers, kids who’ve outgrown their twin beds, or young adults. Full size mattresses will fit in a room with 9.6 x 10.6 feet of space but are ideal for rooms measuring 10 x 12 feet. Full XL mattresses also fit these room sizes—just keep the extra five inches of length in mind!

Twin/Twin XL  

Twin size mattresses are 39 x 75 inches and are perfect as your child’s first big-kid bed or as a guest bed! Twin mattresses fit best in spaces that are 7 x 10 feet, but if you need to fit two twin beds, make sure your space is around 10 x 10 feet so everyone has enough room.

Twin XL mattresses offer more legroom (good for kiddos who never stop growing!) and fit well in spaces measuring 7 x 10 feet.
