Before we move on to other methods of selecting the right size for a bed, let's first explore how important it is for couples sharing a bed to consider this Mattress Size Guide. Why is this? Simply because many times we have ended up not buying the size that we thought should be purchased. For instance, most of the time, if two persons share the same bed and are purchasing it, they tend to assume that they are purchasing two beds. But in reality, they are purchasing one king-size bed for the single sleepers. This mistake can easily be avoided with the help of a Mattress Size Guide.

Now you may ask why exactly do we need a Mattress Size Guide? 

Well, this is very simple. Most of the time, if you go to a retail-locator store to buy a new mattress or bed, what happens is you will be offered a few sizes. Now, if you were to ask these retail experts the actual measurement of these beds and sizes they would tell you that these beds are available in 16 inches, nine inches, six inches, four inches, three inches, two inches, one inch, half an inch, even an inch.

Now ask yourself, what does all this mean? 

It means that most of the time when you go to purchase a bed, you end up purchasing a bed that is much too small for your needs. What is the purpose of getting a new bed? Well, most people get a twin or queen so that they can save some space in their bedroom. Moreover, a twin or queen is also perfect if one person is sleeping on the floor while the other sleeps on the top bunk.

However, what about those of us who are purchasing a full-size bed or even a king? Now, most people tend to think that we don't need to know the size of our bed. But is this true? Do we not need to know the legroom of our room?

Size of Room

Let me remind you once again, the size of our room has to do with the size of our beds. So let us look at the following example: If you are going to sleep on the floor, it would be better if you choose a twin mattress dimension that is only three inches wider than you are tall for the sake of comfort. If you are going to sleep on the top bunk, then you should choose a full-sized twin mattress dimension that is just over one and a half inches taller than you. This way, you will be able to maximize your comfort and enjoyment.

Do you have a Single Sleeper's Room? In this case, you would want to go with twin-size mattresses. This is because single sleepers can easily bump into each other when sharing a room. On the other hand, you will not have this problem if you have two twin mattresses instead.

Is Your Room Big Enough? For those who have spacious homes, they would always prefer to go with king-sized or queen-sized mattresses. This is because these provide enough space and allow you to make use of it properly. You also do not have to worry about sharing a bed with another person.

Are you still not convinced with these King mattress dimensions? You should know that twin size is just an inch smaller than a king mattress. Also, it takes about six to eight hours for you to get used to sleeping on a twin mattress. The good thing is that you can still get plenty of sleep because of this.

Mattress size is very important to consider when you buy a new mattress. You want to make sure that the mattress you get will fit perfectly into the room you are getting it for. Many people are not aware of the standard bed sizes for mattresses and the reason they should be because there are different types of mattresses available on the market today. There are box spring mattresses, coil springs, foam mattresses, memory foam, and many more.

Mattress Size Chart

When it comes to mattresses, a mattress size chart and the various mattress size measurements are helpful so that you can easily determine what size mattress to get for the king, queen, or twin bed. It lists the width, depth, and thickness of the mattress. For example, if you have a king mattress, the chart would read either as "King - X 75" or "King - X 80". This terminology is helpful because it allows you to know in what size to get the mattress.

Dimensions

The next thing you want to know is the standard mattress dimensions for all three sizes of beds. It should be between twenty-eight to twenty-nine inches wide, between twenty-two to twenty-four inches deep and between twenty-six to twenty-eight inches long. The standard mattress dimensions are usually based on the height of the person who will be sleeping on the bed.

Width

The next thing that is listed is the width of the bed from the floor to the top of the head of the bed. It should be between twenty-two to twenty-four inches. The length of the bed should be from floor to ceiling, including the top of the head. The king mattress dimensions are going to be between twenty-eight to twenty-nine inches wide, between twenty-two to twenty-four inches deep and between twenty-six to twenty-eight inches long.

The thickness of the mattress dimensions is between seven and ten inches wide and between ten to fifteen inches long. The next thing that is listed is the height of the mattress. It should be between twenty-two to twenty-four inches high.

The third thing that is listed is the width of the bed and the depth of the bed. This should be between one and two feet wide and between two and four feet deep.
