How To Measure
First let me show you how a mattress is measured so that we’re on the same page and using the same terms. Then we’ll talk sizes.The height of a bed is measured from where you’d lay your head down to where your feet rest. The width is measured from side to side or the same direction if you extended both your arms horizontally while laying on the mattress. Not as commonly used is the mattress profile. That’s basically how thick the mattress is from where it touches the box spring to where you lay on it. You’ll need to keep that in mind for buying your sheets.

Twin or Single Size
More commonly known as a twin size mattress its also referred to as “a single.” This is a great size for children and teenagers. Investing in a quality twin mattress can sometimes last a child all the way to college.
Full or Double Size
More commonly known as a full size mattress its also referred to as “a double.” A full size is the same height as a twin but is wider. Its a great bed for a child that tends to move a lot from side to side.
The most popular mattress size, a queen is large enough to comfortably fit an adult couple. Its height is more than a twin and full but the same as a king. Upgrading to a king gives more room widthwise (6 inches).
There are two types of king size mattresses: Eastern King and California King. The Eastern King is usually referred to just as “King” and is as tall as a queen but wider. The California King usually is shortened to “Cal King” and is taller than a regular king (4 inches taller) but less widthwise (4 inches).
