An Ultimate Guide to Double Beds | Types, Sizes, Other Variations

After the hustle of the day, where do you end up in your bed? A bed is the ultimate thing that makes you feel at home- that is why you cannot compromise on the comfort level, size, and warmth of your bed. Whether you are looking for a new mattress or concerned about its width in general, its many types and sizes will surely confuse you. So, this post will ease your way through the lingua of beds and mattresses.  

In general, the double bed size is the one that can fit two people, regardless of the size. For starters, this concise definition can set the standard for you. But, many people confuse its types with its dimensions. To resolve that confusion, we’ll move on to the actual debate- the double bed.

What is a double bed?

Back in the 1940s, when nobody was familiar with the term king or queen-size beds, a standard bed size of 27 inches by 75 inches was used for sleeping. Little did they know that this size was not enough for a healthy good night’s sleep. Regardless of the size, it was considered a full double bed for two people. More interestingly, what they use to call a double bed could only suffice one sleeper. 

What is full size mattress?

A full-size mattress is the same thing as a double bed. It is best suited to rooms with 10 by 10 feet area length and width. No matter the bed and the room size: a perfect double bed with a mattress is the one that leaves a 2 to 3 feet area to walk around the three sides of the bed. In that case, these full-sized mattresses/beds are best for typical studio apartments. 

Dimensions of a standard size double bed:

  • A full mattress/double bed is 54 inches X 75 inches.
  • 54 inches or 4 feet 6 inches are the dimensions of the width of a double bed.
  • Six feet three inches is the length of a full-size double bed or 75 inches.
  • The width is perfect for a sleeper but cramped for two.
  • The length is perfect for people under 6 feet but cramped for those over 6 feet. 

Types of double beds with sizes:

Typically, it is rare to find the exact XL or double XL sizes in beds and mattresses simultaneously. That is why one should consider the type of bed before finding a double bed for sale. To make that debate clearer for you, let’s move on to the various sizes of double beds/full-size mattresses. So, other standard mattresses exist on the market with the names of:

  1. Twin size mattress
  2. Twin XL size mattress
  3. Queen size mattress
  4. King size mattress
  5. California King size mattress

Types of double beds with sizes

1. Twin size mattress:

A twin-size mattress is 38 inches by 75 inches. It comes in a compact form, perfect for young rooms or single adults who want to save space without sacrificing comfort. They can also fit well with bunk beds, which means you do not have to give up floor space. If you are not a teen, rethink this bed size.

3. Twin XL size mattress:

The Twin XL size mattress is 5 inches longer and 16 inches narrower than the full size. Measuring 38 by 80, this extra-length bed can accommodate growing teenagers in a kids’ room or a shared bedroom. Additionally, you can turn these bed types into a folded double bed to fit perfectly into an individual small bedroom.

4. Queen size mattress:

Queen size mattresses are the most popular of all mattress sizes. The dimensions of a queen-size mattress are 60 inches by 80 inches. As compared to full-size beds, queen mattresses are 6 inches wider and 5 inches longer. Also, they are suitable for singles as well as couples. A queen-size bed can be kept in either your guest room or your master bedroom. Plus, the extra width is especially beneficial for restless sleepers.

5. King size mattress:

When it comes to mattresses, a king-size mattress is the largest in terms of width. If you and your partner need more space to sleep, consider one of these king-sized beds, which measure 76 by 80 inches. These double king-size beds are large enough for children: if they want to sleep alongside their parents on some nights. But they are not too big for adults either. In comparison to a full-size bed, king beds are 22 inches wide and 5 inches longer.

5. California king size mattress:

It’s no secret that California king-sized beds are the longest of all the standard-sized beds available. For tall people, cal-king beds measure 72 x 84 inches. California king beds, like king mattresses, are ideal for master bedrooms with large spaces. A larger and taller than full-size beds, California king mattresses are 18 inches wide and 9 inches long. Unfortunately, you rarely get to see this double bed with storage these days.

Although the table above makes it pretty clear: based on the size, type, and dimensions, drawing a comparison can make a huge difference. Let’s take this debate a little bit forward.

Double bed vs. queen size bed:

The clear-cut difference between these two-bed sizes is that a full double bed barely fits two people. However, a queen-size mattress has enough space and comfort level for two adults. In most cases, people think that a queen mattress/bed is designed for two people specifically. Honestly, that is not always the case- it is perfect for an adult who does not like to sacrifice personal space. 

On the subject of size, a queen size bed is 6 inches wider than a double bed. A queen mattress is about 60 x 80 inches, while a full double-size is 54 x 75 inches. So, next time when you stay in a hotel room, you’ll notice that it is a queen-size bed. 

The average cost of a full-size bed:

Depending on the size of the mattress and quality craftsmanship, a full-size bed/mattress can range from $200 to $2000. And for a premium luxury-size bed, you can expect to pay from $1200 to $1500. Fortunately, AVRS furniture has a top-quality and versatile collection of double bed sizes at the most reasonable prices ever.
