This guide an air mattress sizes is long overdue. That’s why we took the time to make this guide comprehensive but simple. We tried to cover any question that you might have, from the true dimensions of a twin, full, king or queen size air mattress.

We’ve been receiving questions about the dimensions pretty much since we started the and we never got around to doing the guide as it should be done.

Most importantly we’ll address the issue of where is the confusion in the first place. This is the one guide on airbed sizes to rule them all.

We will also get into sizes of camping blow up beds and how to match them to tent sizes.

Basically, we’ll cover everything.

Air mattress sizes chart

In theory, air mattresses come in same size as regular mattresses. The fact that they are perceived or actually be smaller is something we’ll address in a minute, also listing which of the top models is true to size and which isn’t, but before we move on let’s take a look at the size chart once more.

Dimensions of a single air mattress

There’s no much choice among single air mattresses, and it’s our opinion that h only model worth mentioning here is the Zaltana Navy Blue.

The size of the single air mattress is 72 x 29 x 7.5 and you can see it below.

Dimensions of twin size inflatable beds

The dimensions of the sleeping surface of a twin size bed is the same with all of them (75 x35) and they only vary in height.

These are a few examples of what we’re talking about:

  • LOW – Intex Classic (12 inches high)
  • MEDIUM – Intex Raised (16.5 inches high)
  • REGULAR HIGH – Intex Comfort (18 inches)
  • EXTRA HIGH – Fox Plush (20 inches)
  • EZ Beds – Ivation EZ (22 inches high)

King air mattress sizes – dimensions and examples

  • 8 “ (Coleman 4-in-1 EasyStay)
  • 9 “ (Aerobed 2-Zone)
  • 25 “ (Fox)

California King air mattress

California king size measures a whopping 84 x 72 inches and there are two airbeds in the category that we’d like to mention and they come from two different worlds. The sizes of these air mattresses make them a choice for a select few.

The first is the extra durable (40% thicker vinyl makes it the best option for heavy people), Fox Plush, and the second one is a luxury adjustable air mattress, the Innomax Medallion.

The height of the Fox is 20 inches while the Medallion that sits at 15 inches.

What’s the source of the confusion about air mattress sizes in the first place?

  1. It’s the fact that airbeds (99% of them) are made of PVC and there are three main reasons why an airbed might feel (or be) smaller than regular mattresses:
  2. Depending on the temperatures and weight of the sleeper PVC stretches, so the same amount of air needs to fill a larger space. When that happens, the sleeper sinks a bit into the middle of the air mattress slightly raising the sides. The result is a subjective feeling of the airbed being smaller.
  3. The air mattress develops a pinhole leak and basically it’s the same scenario described in point 1 (above). The industry’s response to that was a never-flat pump – this small pump seamlessly adds air through the night and is activated by pressure changes.
  4. The airbeds might actually be made smaller out of the factory. We’ve seen it, and we’ve seen it from some reputable brands – air mattresses or sleeping pads not being true to size. We’ve covered the top models and whether they have the issue in the table above.

The beds we listed as examples are all true to size.

One final question we get asked a lot:

What size tent fits a queen air mattress?

As we’ve seen above, an air mattress covers a base of about 32 feet square.

To be comfortable and not bump into stuff all the time, a twin size air mattress will be a good fit for tent with base that’s about three times as big.

To fit a queen size air mattress, we wouldn’t recommend a tent smaller than 10×10 feet.

If it’s a square dome tent, 8 foot will suffice but with a slopping canopy tent of that size, things can get claustrophobic.
