Can’t decide on what air bed size to get for your guest room or tent? Don’t worry, we know that air mattress sizes can be inaccurate sometimes and we’re here to help. In this article, we tell you about the different dimensions and how to choose the size that’s best for your needs.


Different air mattress sizes in inches

Twin XL38" x 80"
Full54" x 75"
Queen60" x 80"
King76" x 80"
California King72" x 84"

Did you notice something in the table above? Yes, air mattresses have the same dimensions as standard mattress sizes. But unlike traditional mattresses which have strict measurements to pair with foundations and bed frames, air mattresses may have slight size inconsistencies.

That said, air mattress dimensions are definitely based on the six standard US mattress sizes. These are your twins, queens, kings etc.

While an air mattress does have a different design and construction, it still provides the same sleeping space as a regular memory foam or hybrid mattress. I go over each air mattress size below to give you a clear idea of the benefits they offer and who they are a good fit for.

Twin air mattress dimensions

A twin air mattress is 38 inches wide and 75 inches long.

It’s the smallest air mattress size available and it’s also the most affordable. Are you looking for an air mattress for your kid’s bedroom? Or maybe you need one for their camping tent? A twin air mattress is going to be your best bet.

You can fit a child on it and even a smaller adult. But a twin mattress does have one caveat, and that’s its length. We don’t recommend it for tall individuals because it might not provide enough legroom.

Twin XL air mattress dimensions

At 38 inches wide and 80 inches long, a twin XL air mattress is a twin’s taller brother.

It offers much of the same benefits as a twin-size air mattress but it’s also designed to accommodate more long-legged sleepers.

Since twin XL beds are commonly used in college dorm rooms, a twin XL air mattress can be a great option for college students who are traveling or going camping.

Full air mattress dimensions

Moving to the bigger sizes, a full-size air mattress is 54 inches wide and 75 inches long.

This air mattress size is ideal for single adults who frequently go on trips, or those who need a suitable mattress for their guest room.

Although it’s possible for a full-size air mattress to accommodate two people, you should expect to feel somewhat cramped. We recommend getting an air mattress that’s at least Queen size if you’re going to be sleeping on it with a partner.

Queen air mattress dimensions

At 60″ x 80″, Queen is the most popular air mattress size.

A Queen air mattress is the sweet spot for most couples as well as individuals who prefer having extra space. You can use a Queen air mattress when traveling or camping with your partner.

Whether it’s for your tent, car, or your guest room, Queen air mattresses are a solid choice that offer a lot of value. One potential drawback with the Queen air mattress size is it might not provide enough legroom for taller couples.

King air mattress dimensions

King size air mattresses are 76 inches wide and 80 inches long.

They are the biggest air mattress size and are more expensive than the rest of the sizes. The King air mattress size is perfect for couples who have bigger body types, or those who prefer a more luxurious and spacious mattress.

It isn’t commonly used for camping or traveling, but it’s widely used by couples in master bedrooms. It has the same problem as the Queen air mattress size which is the lack of legroom for couples who are taller than average.

California King air mattress dimensions

At 72 inches wide and 84 inches long, California King is the longest air mattress size.

Similarly priced as King air mattresses, a California King air mattress is best suited for couples who are taller than average.

However, a California King air mattress is pretty rare and there are only a few brands that sell them. A California King air mattress is also a bit narrower than a King air mattress. If you’re looking for a wider sleeping space, go for a King-size air mattress instead.


How to choose the right size air mattress

Consider these factors when choosing an air mattress size:

  • Size of your room
  • Height and weight of the sleeper
  • How many people will be sleeping on it?

Now that you know all about the different air bed/inflatable bed dimensions, it’s time to learn how to select the right size for your specific needs and situation. I go into more detail on each of these factors below to give you all the info you need to make a decision that benefits you and your family.

Size of your room

If it’s for camping or traveling purposes, you should get a smaller air mattress size such as a twin or full. Check out our best air mattresses for camping article for high-quality options.

These smaller air mattress sizes are also great for studio apartments, kids’ bedrooms and college dorm rooms.

On the other hand, those with bigger bedrooms can get a Queen, King, or California King air mattress.

Height and weight of the sleeper

Another important factor in choosing an air mattress is your body type. Are you an average-weight individual or are you someone who weighs more than 250 lbs.? Are you tall or short? You need to make sure that the air mattress you choose has the correct weight limit.

We recommend that heavier people choose a bigger mattress that provides ample sleeping space. Although couples generally lean towards Queen-size mattresses, taller individuals will get more legroom on California King beds.

How many people will be sleeping on it?

Are you going to be sleeping alone or with a partner? Children and young teenagers can sleep on a twin air mattress, while a single adult should get adequate space on a full-size mattress.

For the couples reading, we recommend getting at least a Queen air mattress to be comfortable and not feel too cramped. If you practice co-sleeping, you should opt for a King air mattress or oversized mattresses such as Wyoming King and Alaskan King.


FAQs

Conclusion

Are you ready to choose an air mattress size? Having the same dimensions as traditional mattresses, air mattress sizes range from twin all the way to California King. When choosing an air mattress size, consider your room size, body type, and the number of people who will be sleeping on it.
