Dimensions for an Air Mattress

Air beds have emerged as a popular alternative to conventional mattresses in recent years. They are not only easy to stow away, but also provide a pleasant night's sleep. Length, width, and height are the standard units of measurement for an air bed. This is because different sized ones are better suited to various tasks.  

The standard dimensions for a twin air bed are 75 by 39 by 18 inches. The standard dimensions for a twin XL air bed are 80 by 39 by 19. The standard dimensions for a full-size air bed are 90 inches wide, 54 inches long, and 17 inches high. The standard dimensions for a Queen air bed are 80 inches long, 60 inches wide, and 18 inches in depth. The standard dimensions for a King-sized air bed are 80 inches long, 76 inches wide, and 16 inches thick. The typical dimensions for a California king air bed are 84 inches long, 72 inches wide, and 20 inches high.

Perfect for camping so you don't have to sleep on the hard ground One or two guests can sleep comfortably in one of these, depending on the size. Use this guide to determine what size air mattress is best for you.

Dimensions of Air Beds

Size variations in air beds mean they have different applications.

There are a variety of standard air mattress sizes, including twin, twin XL, full, queen, king, and California king. Most air mattresses have a height of between 6 and 18 inches.

A small airbed, roughly the size of a twin

Standard dimensions for a twin air mattress are 75 by 39 by 18 inches. Only one person can sleep comfortably on a twin-sized air mattress. Nonetheless, a double- or single-tall air mattress of the same width (length) as a standard twin will have a different height (thickness). A single-tall air mattress is shorter and narrower than a double-tall mattress, typically measuring in at under 10 inches in height despite having the same length and width. When pitching a tent, a thinner mattress can come in handy because it takes up less room. Twin size mattresses that fold up into a single tall unit are ideal for car camping due to limited storage space. Moreover, it will work wonderfully for truck camping.

To Inflate a Twin XL Bed

Twin XL air mattresses are ideal for those who are taller or heavier, as their extra length makes them more comfortable. Still, it's only designed for a single occupant. Common dimensions (L x W) are 80" x 39". While a twin XL air mattress may work for tent camping, it is too large to fit in most automobiles for use while on the road.

Measurements for a Full-Size Air Mattress

Standard dimensions for a full-size, double-high air mattress are 75 by 54 by 17 inches (inches). The full size is often called a "double" because it is large enough to accommodate two people. It's the perfect size for around the house or a weekend camping trip. Full-size air mattresses come in both single- and double-height heights; the difference between the two is the thickness. The dimensions of a standard full-size air mattress are 75 by 54 by 10 inches (length, width, and height, respectively). When compared to the thicker version, this one is preferable for camping in a car or truck. Of course, the thinner full-size air mattress can also be used inside.

You can also find longer versions of standard full-size air mattresses, with dimensions of 90 by 54 inches (length by width). A true XL, these are the real deal! If you do happen to come across one of these, measure the area where you intend to put it to ensure it will be a suitable fit. It's probably too big to fit in a regular car or truck.

Airbed, Queen Size

Air mattresses come in a variety of sizes, but a typical queen-size one is 80 by 60 by 18 inches (inches). An air mattress of this size is great for indoor use, especially if you frequently have guests over. If you have a large enough tent, it can also be a pleasant camping experience. However, a queen-size air mattress that is double-high won't work for camping in a car or truck. Queen air mattresses typically measure 80 by 60 by 10 inches (L by W by H). In general, two people who weigh less than 650 pounds combined will be comfortable on a double air mattress of this size.

Which Size of Air Mattress Is Ideal for a Guest Room?

The adaptability of air mattresses is a great benefit. A portable air mattress can be stashed away until needed, or it can be kept out and ready. The versatility of air beds allows you to put your spare bedroom to many uses.

The number of overnight guests in a room is the starting point for selecting an appropriate air mattress size. The next step is to decide whether or not guests will sleep in separate beds. Finally, figure out how much everyone is weighing, and make sure the air mattress can support everyone plus their bedding.

Step 1 In your guest room, how many people do you anticipate?

Which type of air bed you'll need depends on how many visitors you plan on having in your guest room. If you're looking for a mattress, how many people will be sleeping on it? Is a shared bed sufficient, or do you need extra beds for each of these visitors? Can we assume that they are adults or minors? Will there be a range in number and kind of attendees? It's important to keep in mind that using inflatable beds can be dangerous for infants, as explained in this article from Intex, a manufacturer of air beds. This child's air bed is the perfect solution for a toddler, while this double high air bed is suitable for an adult.  

Step 2 How Many People Share Each Bed?

Sharing a bed is a major factor to think about. The use of air beds is recommended if you do not want your guests to share a bed. In order to fit in the space, they will need to reduce in size. These convenient twin air mattress sets can accommodate a number of guests at once.

Step 3 Pick the Right Size of Air Mattress

A single traveler will fit comfortably on a twin-sized air mattress. A full-size air bed is sufficient if you plan to have two guests share a bed. You'll need two or more air beds, preferably in separate rooms, if your guests aren't all going to share a single bed.

Bringing an Air Bed on a Road Trip

One of the most enjoyable activities is car camping. If you have the right air mattress, you can sleep soundly and easily in your vehicle. When the back seats are folded all the way down, most SUVs and utility vehicles can easily fit an air bed inside.

If you want to go SUV camping with an air mattress, you should get a mattress that fits the available space in the back of the vehicle (usually measured in feet). Since the trunk and rear seat area of a sedan are typically more compact, you should purchase an air mattress tailored to the make and model of your vehicle.  

The size of a car's rear compartments varies greatly depending on the model. In order to determine whether or not your SUV has enough room for an air mattress, you need only measure the flat, open space created when the seats are lowered. For convenience in transport, select a single-height air bed. Pick an air mattress made specifically for automobile use if you plan on doing any car camping in your sedan.
