Bed Sizes in Order – 7 Most Common Bed Sizes US

There are seven standard sizes of beds in the United States. As mentioned earlier, here is the full list of these bed sizes in order:

  1. Crib: 27″ x 52″
  2. Twin: 39” x 75”
  3. Twin XL:  39” x 80”
  4. Full: 54” x 75”
  5. Queen: 60” x 80”
  6. King: 76” x 80”
  7. Cal King: 72” x 84”

The most common of these seven bed sizes are twin, full, queen, and king. These four are commonly regarded as the standard bed sizes in the US. However, owing to the requirements and desires of customers, there are a few variations in these standard sizes. These size variations include the California king, twin extra-long, and crib.

A crib bed is, of course, designed for small kids and is mostly used in children’s rooms.

Also, as you may know already, despite its name, a twin size bed is for one person only. It’s called a “twin” bed because it is supposed to be one of a matching pair of single beds. Twin beds are usually used in a room shared by siblings or in a guest room or hotel that has more than one person.

A twin bed XL is simply a twin bed that is a bit longer, about five inches long to be exact.

A full bed is also sometimes called a double bed. Two children can be comfortably accommodated in a full bed, but it can be quite narrow for two grownups.

A queen bed, on the other hand, has more than enough sleeping space for two adults who are of average size.

A king bed gives plenty of sleeping space for two adults.

Those who are taller than 6 feet tall will be more comfortable with the space provided by a California king bed. A California king bed size (or Cal king) is about four inches longer than a king bed. However, the Cal king bed is 4 inches narrower in width than the king bed.

Details and Specifications of Bed Sizes

In this section, I will give more details for each standard bed size. These details will help you assess the correct bed size that will meet your particular needs.

1. Crib

The crib is the smallest bed size among the standard beds in the United States. It is also called a ‘toddler bed’ and can be used as the first bed of your baby. Its 27″ x 52″ dimensions can easily fit into any standard crib frame.

For safety reasons, crib beds have tough and hard mattresses – harder and tougher than adult mattresses. Babies can use them up to their toddler years. Some crib beds are lighter than others to make them easier to move around.

2. Twin Size Bed

The twin bed, with its 38″ x 75″ dimensions, is slightly shorter than the twin XL. Kids can use this bed throughout their childhood. It can provide adequate sleeping space for one child from his toddler years up to his teen years. An average-sized adult will not be comfortable sleeping in this bed.

It is a slim-sized bed that is easy to maneuver inside a room. Also, it is easy to fit side by side with similar-sized beds in rooms shared by two or three kids. You can also put several twin beds in odd-shaped and smaller guest rooms.

The Max & Lily 180210-121 Platform Bed is an example of a great twin bed size.

This bed is made of a durable, solid New Zealand pine wood bed frame. It has metal-on-metal structural connections that won’t loosen over time. It is easy to assemble and holds up to 400 pounds.

3. Twin XL Size Bed

The twin XL bed is designed for dormitories. With its 38″ x 80″ dimensions, it should provide enough stretching space for average-sized students. These beds are designed to save space. It also provides a sleeping space similar to any twin bed. However, it has a longer length, providing taller students with more legroom space.

If you are thinking of upgrading beds in your dorm, or if you want to provide more sleeping space for your growing children, you need to consider the twin XL. Its price point is friendlier, and it can be moved around with ease.

An excellent example of this bed size is the KD Frames Lexington Platform Bed, XL-Twin.

It has a 2.8-inch space between slats and does not require a box spring. The wooden frame is made of real, smooth, and unfinished tulip poplar. It also comes with a five-year manufacturer’s warranty.

4. Full Size Bed

Full size beds measure 54 inches x 75 inches. This bed size is the natural upgrade of the twin bed. If you are single, this bed will give you more than enough space. But if you are a couple, you will only have the equivalent space provided by a crib bed, and the quality of your sleep may not be as restful as you want.

A full bed is a good compromise between a queen and a twin bed. They are perfect for teens who have outgrown their cribs. Also, young graduates will welcome the size of a full bed and its affordable price as they move into their own apartments. Full size beds are also good investments since they can be used in guestrooms once the kids grow and move out of the house.

One good example of a full size bed is the Max & Lily 180211-121 Platform.

Like the Max & Lily Twin bed, the full bed is made of genuine, durable, solid New Zealand pine wood bed frame. It has a larger bed size than many other full size beds at 80 x 58 x 37 in (L x W x H).

5. Queen Size Bed

Queen size beds are the most popular in the United States. That’s easy to see because their 60″ x 80″ dimensions can fit into smaller bedrooms and yet provide couples with enough space for comfortable sleeping. A queen size bed is the most versatile of all bed sizes.

A queen size bed also provides good service for a long time, whether you’re single or have a partner. This bed size can easily fit into many master’s bedrooms. Its popularity also means that you won’t find any difficulty buying matching beddings and accessories, which tend to be affordable and still of high quality.

The Zinus Gerard Platform Bed is a good example of a queen-size bed.

It has a beautiful espresso faux leather upholstery with a steel framework. It is an eco-safe, chemical-free bed frame with a 5-year manufacturer’s warranty. The durable wood slats support and extend the life of your memory foam, latex, or spring mattress without having to use a box spring.

6. King Size Bed

If you really want ample sleeping space, go for the king size bed. Its 76″ x 80″ dimensions will surely provide you with more than enough space you will need. Couples will each get the equivalent space of a twin bed in a king size bed.

King size beds are ideal for couples who share their beds with their kids or pets. However, because of their larger size, couples must be ready to face difficulties when moving the bed from one room to another. There are king size beds that consist of two twin box springs, which can be put on top of the other to make them easier to move around.

If you need a king-size bed, you can consider the Zinus Shalini Upholstered Diamond Stitched Platform Bed.

7. Cal King Size Bed

different bed sizes in us

What about beds bigger than king size? The longest bed in our list of the most common bed sizes USA is the Cal king bed size. The Cal king or California king size bed cuts four inches of the standard king size width and adds them to the length of the bed. This bed size makes it an ideal bed for those who are 6 feet tall and taller. It measures 72″ x 84″, making it the largest of all the standard-sized beds.

If you are tall and frequently having your feet hanging off the edge of your bed, use a Cal king bed. A Cal King bed will provide you with all the foot space you need. For average couples, the size of this bed will give them plenty of space. It is also narrower than a regular king size bed, so it can fit in most rooms that accommodate larger beds.

The Zinus Gerard Deluxe Faux Leather Upholstered Platform Bed is a Cal king bed.

What Is the Difference Between Bed Sizes and Mattress Sizes?

You might be confused by the way bed manufacturers are selling their products. Some indicate US bed sizes, others give mattress sizes, while others specify both bed and mattress sizes. So, which of these terms should you use when choosing a bed?

In a majority of cases, there is really no difference between bed and mattress sizes. They are often used interchangeably with one another. Typically, when a manufacturer gives the bed size, it could mean a mattress, bed frame, or headboard.

Bed manufacturers will not list bed dimensions that include some accessories. The reason is that US bed sizes and mattresses do vary. Moreover, a majority of these mattresses and beds are compatible with many bed accessories.

Things You Should Know About Bed Sizes

There are some things that you might have assumed about bed sizes in the US. Below are some interesting questions and answers which may surprise you.

1. Is a Double Bed the Same Size as a Full Bed?

Yes, the terms double bed and full bed are used to describe the same bed size. They both measure 54 inches wide and 75 inches long. Some people tend to incorrectly assume that ‘double’ means ‘double the size of a twin bed.’

They may have the same length, but the width of a full mattress is 15 inches wider than that of a twin bed. So, bed manufacturers dropped the term ‘double.’ The term ‘full bed’ has replaced the term ‘double’ in modern times.

2. What Is the Most Popular Size of Bed in the United States?

The most popular bed size in the US is queen size. Compared to a king size bed, a queen bed is 16 inches narrower. This narrower width allows the queen bed to move more easily through narrow spaces, such as staircases and doorways. A king bed can be quite difficult to move in and out of a home.

Queen size beds are also priced in the middle. Considering all factors involved, that means they are neither cheap nor expensive.

3. What Is the Biggest Bed Size?

The most common biggest bed size is the king and Cal king; however, there is another bed size that isn’t as common but is bigger. Beds bigger than the king include the Cal King (4 inches longer but 4 inches narrower) and the Alaskan king.

The biggest bed size available is considered to be the Alaskan king bed. The dimensions of this bed are huge. Its length and width are the same at 108 inches. The Alaskan King bed is 28 inches longer than a king size bed. It is not too common, so it is not included in the list of standard bed sizes US; however, it shouldn’t be too hard to find an Alaskan king bed if you really need lots of room to spread out.

Largest bed size – Alaskan king bed

The Alaskan king bed is the width of two full beds. If you share this bed with your partner, each of you will enjoy 54 inches of moving space, which is already as big as the size of a full bed.

4. What Is This Super King or Texas Size Bed?

Aside from the standard bed sizes, bed manufacturers have built what they call ‘specialty’ bed sizes. They are not widely promoted but are often made by some bed manufacturers based on the demand of a small segment of consumers.

People who have special requirements are the ones who buy these specialty beds. But be aware that it is rather difficult to find the right mattresses that will be compatible with these special size beds. The same goes for the bedding accessories.
