A few years ago when I was shopping for a mattress and I did not know the size of the mattress. I’m quite embarrassed about that now, but I’m sure there are many others like me. I was buying a mattress online and I did not know the correct size to get so that it would fit on my bed frame and box spring.
So this is why I created this chart and a little guide to help you when you’re getting a new mattress and need to know the correct size to get.
Here is a chart to show you the different common sizes (small to big) in inches for mattresses…
As you can see above you have all the common types of mattresses that you would find. Some mattresses might be off by a inch or less due to manufacturing, but this gives you a good idea of what to expect.
The measurements are in inches.
What if you don’t have a tape measure handy?
If you don’t have a tape measure handy and need to know how big your bed frame or box spring is then just grab a dollar bill. A dollar is 6.14 inches long, or just about 6 inches long. A queen mattress is about 60 inches long or about 10 dollar bills long. Clever isn’t it!
Platform Bed Frame
If you’re planning on starting with a new mattress and a new bed frame then check out a platform bed. Its a much cleaner look and simpler too. Some even give you great storage under them compared to the old style bed frames.
This is what I did, started new with a new bed frame and mattress which solved my issue of making sure I had the correct mattress to bed frame.
What are some examples of each size of mattresses?
Here are some examples of each mattress in each size to help you better understand prices, reviews, and common questions people might have with them.
Twin – 39 x 74
Twin XL – 39 x 80
Full – 54 x 74
Queen – 60 x 80
King – 76 x 80
California King – 72 x 84
A twin mattress is the smallest besides a crib mattress. This mattress is the next step up from the crib and is recommend for children or small adults.
If you have a child that is becoming an adult or is on the taller side then a Twin XL might be the best way to go.
Twin XL Mattress
A Twin XL bed is the same width as the regular twin mattress but it is 6 inches longer (one dollar bill longer like in the measurements we use above). If you’re trying to choose between a Twin or an XL then go with a XL since its a little bit bigger.
If a bed frame is a concern you can get some bed frames like this one that fits many different size mattress and box springs.
A full mattress is a wide twin mattress. Two people could sleep on it, but it will be very uncomfortable to do so. A full mattress is so much better than a twin since it gives you room to spread out when you sleep if its only one person. Still not the best for tall people, but heavier people who sleep by themselves will find this size to be the best suited for them.
The queen mattress is probably the most popular mattress size of any of them. There is so many more bedding accessories like bed sheets and pillows for a queen size mattress than any other size. If you’re in doubt about what mattress size to get then get a queen.
A queen is a wider Twin XL mattress and bigger than a Full Mattress. A queen is the smallest you want to go with if two people are sleeping in one bed.
If you’re like me, over 6 feet and over 200 pounds then you might want to stick with a King Size Mattress.
A standard or Eastern King Mattress is the next biggest one. There is some mattress that are bigger than it, but we’ll go into detail about that later on.
A King Mattress is a wider and more roomy Queen Mattress. Its the best size if you want to be able to sleep in any direction or you enjoy your sleeping space. I know the movies have us believe that all happy couples sleep close together, but let’s be real, real couples enjoy there sleeping space.
California King Mattress
There exist two types of King Mattresses, a Eastern King and a Western or California King. One is not really better than the other, a Eastern King is more poplar but a Cali King less wide but taller.
All a Cali King does is take away 4 inches from the width and place in the height. That is it.
Not saying its harder to find bed sheets for a California King, but a Eastern or just a regular King Size mattress will have more options.
The mattress sizes above are the most common, but there exist a ton more. You can of course get custom made mattresses to fit any need you have.
Let us talk about the other sizes of mattress. You may have thought a King Mattress was big, but what if you need something bigger? Well then you need to get the Grand King, or also called the Super king, Athletic King or Texas king mattress. Here is a size comparison of it to a normal Eastern King and a Twin mattress.
The Grand King is quite large, but also harder to find. The Grand King is 80 x 98 inches, compared to the Eastern King’s 76 x 80 that is a big mattress. The Grand King is best for the taller people and bigger people of the world.
