Does Mattress Size Really Matter?

No matter how much homework you do to select the best mattress type and comfort level, if a mattress is not the right size, it will affect your quality of sleep. A mattress needs to accommodate all potential sleepers - kids, pets, you - while allowing you space to move around your bed comfortably.

Below are some useful tips that can be helpful in guiding you towards a mattress size that is right for you.

CALIFORNIA – 72" (W) x 84" (L)

The "California King Mattress" is approximately 72 inches wide by 84 inches long – 4 inches narrower and 4 inches longer than a regular king.

Are you a person over 6’ tall? The California King is the same width as a standard King, but 4" longer!

KING – 76" (W) x 80" (L)

The king size mattress dimensions are about 18 inches wider than a queen. A king size mattress is the best choice for couples that want maximum personal sleeping space (38 inches each would have on a twin bed; two twin extra-long beds pushed together are about the same size).

It’s also the best bet to accommodate that time on Sunday morning when children may pop into bed – or if the pets in your house have mattress privileges!

However, size can be a problem. Even with a "split boxspring" (two twin-size foundations to support it), it may be too big for some bedrooms or too bulky to navigate through some corridors, doors and stairwells.

QUEEN – 60" (W) x 80" (L)

Queen mattress dimensions are 6 inches wider and 5 inches longer than a full size mattress.

These added inches can make all the difference in comfort, especially for couples, and have made the queen size mattress today’s most popular mattress size. However, with 30 inches of personal space, each adult still has 9 inches less width than if they slept alone in a twin bed.

Queen size is a good choice for guest rooms, smaller master bedrooms and for couples who prefer close quarters. It’s also a great choice for single sleepers who are also "sprawlers ".

FULL – 54" (W) x 75" (L)

A full size mattress is 53 inches wide, which is just 15 inches wider than a twin size (single). That leaves each partner only 27 inches of personal space. Also at approximately 75 inches long, this size may be too short for some adults.

A full size bed is best for a single sleeper, and only if the person is under 5 feet 5 inches tall. Parents are increasingly choosing full size over twin for teenage bedrooms. Parents are even making this choice for younger children in to give themselves a more comfortable place to rest when reading together at tuck-in time.

TWIN – 39" (W) x 75" (L)

A twin mattress is the smallest possible mattress size, other than a crib-sized mattress. Both twin and full sizes are approximately 75 inches long, which may be too short for some adults.

TWIN XL – 39" (W) x 80" (L)

A twin XL might be a good alternative for those living in tight spaces. The XL offers several inches in length, but remains around 38 inches in width. The XL twin is a popular choice in college dormitories.


  • Your mattress should be 6 inches longer than the tallest person sleeping in it.
  • Partners should be able to rest both hands behind their head (elbows sprawled) without bumping into each other.


  • Your mattress must fit through any doorways, corridors and stairwells leading to your bedroom
  • Determine how many people (and pets!) will be in the bed (and how big they are)
  • If you are bed-time reader with your children, a full size mattress may be more comfortable that squeezing onto a twin bed.
