Guide to Mattress Sizes
To help take some of the confusion out of buying a new mattress, Cheap Mattress Reviews was founded to provide you with consumer reviews of all the leading mattresses available today.
One feature of most good mattress review sites is some general buying information for the person just setting out on the journey to get a new mattress. There is a lot of information to take in and many things to consider in getting the right model for the right sleeper in the right room and one of those things is mattress sizes. Here we give you a rundown of what a good guideline to size should be telling you.
A good way of giving you this information succinctly is with a mattress size chart like the one below.
This may be basic, as in this example:
Twin: 38” x 75”
Full: 53” x 75”
Queen: 60” x 80”
King: 76” x 80”
Or it may be slightly more detailed like in this example:
Twin Mattress 39″ wide x 75″ long
Twin XL Mattress 39″ wide x 80″ long
Full Mattress 54″ wide x 75″ long
Full XL Mattress 54″ wide x 80″ long
Queen Mattress 60″ wide x 80″ long
Cal-King Mattress 72″ wide x 84″ long
King Mattress 76″ wide x 80″ long
King Split Mattress 76″ wide x 80″ long
Or it may include even more detail and all the novelty sizes as well as the main ones, such as this:
Single/twin – 39 in × 75 in
Twin extra long – 39 in × 80 in (This size is common in college dormitories)
Three quarter – 48 in × 75 in (often 47-48 in × 72 in sizing varies).
Super single – 48 in × 84 in
Double/full – 54 in × 75 in
Full extra long – 53 in × 80 in
Queen – 60 in × 80 in
Olympic queen – 66 in × 80 in ( a novelty size by Simmons)
King – 76 in × 80 in
Eastern King – 76 in × 80 in (An alternative name for a North American king)
California king – 72 in × 84 in (A common size on the west coast, also called a western king, West Coast king, Cal king, or WC king.)
California queen – 60 in × 84 in
The measurements you see above list the width first and then the length.
This latter example covers all the mattress sizes for North America, but please note that UK, European and Australian sizes are quite different and will need a whole new chart to explain them. This may be a factor if you are buying an imported mattress so just be aware of it.
You can see that it’s no simple business to choose the right size mattress, especially when all the novelty sizes are added. A quick note about the novelty mattress sizes and measurements you see above – they are usually only available from one or two different manufacturers so don’t expect to walk into the average bedding store and see all of the above sizes available. Some sizes may require special ordering. Unless you are particular about wanting a certain size then it’s usually best to stick to the main ones that you see in the first two lists above.
One thing you will want to beware of with your mattress size dimensions is that, if you are upgrading say, from Queen to California King, the latter is 12 inches wider ….so make sure that your room can accommodate it. You wouldn’t be the first person to buy a new mattress only to realize that you should have measured the exact dimensions of your room first!
