Air Mattress Sizes Chart | Find Your Footprint Fast

Air mattress sizes chart match standard bed dimensions: Twin is 38 x 75 inches, Full is 54 x 74–75, Queen is 60 x 80, and King is 76 x 80.

Most air mattress sizes chart listings mirror standard U.S. bed footprints, but the exact numbers vary by brand and model—especially height. The chart below shows the widely used sizes, with the caveat that you should always confirm the inflated dimensions on the product page before you buy sheets or clear floor space.

Standard Air Mattress Sizes: The Basic Chart

The core sizes match familiar bed names, so if you know a standard mattress footprint, you already have a head start. These are the dimensions most manufacturers cite for their air beds.

Notice that Full and Queen are the two most likely to be confused. A Full is only 54 inches wide—noticeably narrower than a Queen’s 60 inches—which matters if two people plan to share it.

Why Exact Dimensions & Height Matter

Brands rarely publish identical numbers for the same size name. SoundAsleep’s Dream Series and CloudNine Series pages both list the queen inflated size as 80 x 60 x 19 inches, while Intex’s U.S. site gives a range from a single at 75 x 39 inches to a queen at 80 x 60 inches, with heights from 8 to 10 inches.

Two things stand out. First, the order can flip—some pages say 60 x 80, others say 80 x 60—but it’s the same footprint either way. Second, height varies wildly, from Intex’s slim 8–10 inches up to SoundAsleep’s 19-inch queen. That height difference changes which fitted sheets fit and whether the bed clears a low frame.

Always check the inflated dimensions before you buy. A “Queen” label alone doesn’t guarantee a 60 x 80 footprint or a particular height, so verify the product page before shopping for sheets or a frame.

Common Mistakes When Buying An Air Mattress

The biggest error is assuming all Queens or all Twins share one footprint. They don’t, and the differences show up in the details below.

• Mixing up Twin and Twin XL: the XL adds 5 inches of length, which is a make-or-break difference for taller sleepers.
• Ignoring height: a 19-inch queen won’t fit a low platform frame the way an 8-inch model will.
• Skipping the product page: some sources publish approximate ranges, but only the manufacturer’s listing gives the exact number for your model.

Treat split-king or split-top sizes as specialty bedding, not universal categories—they show up in some guides but aren’t a standard air-mattress class.
