Bed Smart 101
Finding the right size mattress to buy can be challenging, especially with so many options available. Most brands manufacture all of the standard mattress sizes including Twin, Twin XL, Full, Queen, King and California King, but not every model is available in all of these mattress sizes. The Queen size mattress is the most popular, so virtually every model is available in that size. On the other hand, the Twin XL, Full XL, and California King sizes are not always available for every model. When selecting a mattress size, consider whether you have the space, sleeping with a partner, or how tall you are when shopping. In this guide, we will walk through the all the standard mattress sizes to help you decide the best option for your sleep needs.

Bed Dimensions Size Guide
TWIN SIZE BED DIMENSIONS: 39” X 75”
Have a tight living space such as a guest bedroom or a child’s bedroom? A twin or “single” mattress offers a good option for these areas, along with daybeds and bunk beds. Adult sleepers may need to opt for the twin-xl for added length.
TWIN XL SIZE BED DIMENSIONS: 39” X 80”
The twin-xl gives an extra 5 inches of length for sleepers that are taller. It’s the standard option for dorm rooms when a twin mattress is simply too short.
FULL SIZE BED DIMENSIONS: 54” X 75”
Best for one person, a full size bed or “double” mattress is nice for guest rooms and growing children. The full size bed measurements offer adults added space, though length may still be an issue. Two sleepers would likely have problems on a full mattress, as there would only be 27 inches of space per person.
FULL-XL SIZE BED DIMENSIONS: 54” x 80”
The extra long full size bed provides an extra 5 inches of length for sleepers that are taller. It’s a nice option if you want to avoid upgrading to a queen mattress. Please note that this is a specialty size, which is usually special ordered.
QUEEN BED DIMENSIONS: 60” X 80”
The standard queen size mattress measurement is 60 by 80. Queen mattress dimensions allow extra length and width compared to a twin or full size mattress. The width of a queen size bed is 60 inches providing plenty of space for single sleepers who like to spread out. The length of a queen size bed is 80 inches which is more comfortable for an average height adult.
KING SIZE BED DIMENSIONS: 76” X 80”
On a king or “Eastern/standard king” mattress, the 16 extra inches of length can mean a great deal to sleepers. This is why it is the mattress size of choice for master bedrooms, as two people would each have around 38 inches of space. Make sure that it will fit in the room before purchasing!
CALIFORNIA KING BED DIMENSIONS: 72” x 84”
The California King or “Western King” adds 4 inches of legroom and takes away 4 inches of width from the king mattress. It is the longest mattress available, except for a custom mattress, making it an ideal choice for tall sleepers!

WHich size mattress is the best for me?
Choosing a mattress size is vital to selecting the right bed. Keep the following tips in mind to pinpoint the best mattress size for your next dream bed:
Size of the Sleeper(s):
A slender person will need much less room than two larger adults. For two people, divide the width by two to estimate each person’s sleep room. Having enough space for one’s sleep style (such as if you sprawl out during the night) is critical to a good night’s sleep.
Size of the Room:
It’s true – a king mattress would be nice to have. However, there may not be enough space in the room to justify such a mattress. Allow for space on each side to get in and out of the bed. If you have room for 2 nightstands, you could reduce to one nightstand and have a king. As a bonus, make sure that the mattress will fit through the door and any narrow hallways.
Budget:
That king mattress will likely be more expensive than a twin or full mattress. Make sure that you keep in mind any price differences when looking at mattress sizes. Remember that our mattresses on sale can often level the playing field, giving you a larger mattress for less!
Split Boxes:
Do you live in an older home or one that has tight staircases/hallways? A split box spring can be a solution, as you won’t be able to bend around corners.
Mattress Height:
If you purchase a thick mattress, you could opt for a low profile box spring, which will reduce from 9 inches to 4.5 or 5 inches. This can be crucial for making it easier to get in and out of bed, and especially for the elderly.
