Queen Air Mattress Dimensions: Size Chart, Tent and Truck Fit

The short answer

Intex and Bestway list their queen air mattresses at 60 by 80 inches, but not every maker matches it: SoundAsleep’s camping queen is 58 by 78 inches. The queens charted here are 9 to 20 inches high. On makers’ floor figures, a queen fits the 4-person tents checked here but not a 2-person backpacking tent.

Each maker prints its own inches, and a couple of inches decide whether a bed fits a tent or a truck bed. Every figure below says whose it is, and every fit is worked out from printed numbers you can redo for your own gear.

Air mattress size chart by maker

Sizes are width x length x height in inches, as each maker prints them for the beds named in the notes. Bestway lists length first; it is turned around here so every row reads the same way.

Size	Intex	Bestway	SoundAsleep	Rest Right (home air beds)
Twin	39 x 75 x 10	39 x 74 x 12	38 x 73 x 9	38 x 75
Full	54 x 75 x 10	54 x 75 x 12	size not shown*	54 x 75
Queen	60 x 80 x 10	60 x 80 x 12	60 x 80 x 19 (Dream Series); 58 x 78 x 9 (Camping)	60 x 80
King	72 x 80 x 10	not listed	size not shown*	76 x 80

*SoundAsleep offers Full and King in its Dream Series, but its page shows the inflated size only for the variant selected, so those sizes are not charted here.
SoundAsleep’s camping queen is 58 by 78 by 9 inches on SoundAsleep’s own page; some listings, including our roundup below, give 8 inches. This article uses the maker’s page.
Whose numbers: Intex’s are its Pillow Rest Classic 10-inch beds; Bestway’s are its 12-inch Tritech twin and queen and its SleepSupport full; SoundAsleep’s twin is its Camping Series. Rest Right Mattress, a Texas mattress retailer, lists sizes for the adjustable home air beds it sells, not for camping air mattresses.
Kings differ most. Rest Right’s king is 76 by 80 inches, the figure the top-ranking size charts repeat. Intex’s inflatable king is 72 by 80, 4 inches narrower (worked out from the two figures). Rest Right also lists a twin XL at 38 by 80 inches and a California king at 72 by 84.
Raised beds keep the footprint. Intex lists its 16.5-inch and 20-inch raised queens with built-in pumps at “60in x 80in” too, so on Intex’s figures a raised bed with a built-in pump needs no more floor space, only more headroom.
In feet and centimeters: a 60 x 80-inch queen is 5 feet by 6 feet 8 inches (worked out). Bestway prints its queen as 1.52 by 2.03 meters, or 152 by 203 cm.

Intex’s own FAQ explains why your tape may not agree with the box: “INTEX airbeds state the approximate inflated size,” and the figure moves with “the pressure, ambient temperature” and similar conditions. Its owner’s manual adds: “Dimensions shown are approximate and will vary due to the vinyl temperature and the air temperature.” Cold air also makes a bed feel softer overnight, which our guide to why an air mattress keeps deflating covers.

How much weight each size holds

The capacity a maker prints is for the bed, so add together everyone who sleeps on it. Bestway puts it plainly for its full: it “comfortably fits up to 2 adults, with a weight capacity of 661 lbs (300 kg).”

Size	Intex	Bestway
Twin	300 lb (136 kg)	330 lb (150 kg)
Full	600 lb (272 kg)	661 lb (300 kg)
Queen	600 lb (272 kg)	661 lb (300 kg)
King	600 lb (272 kg)	not listed

Intex prints one figure per size group in its FAQ: “Jr. Twin, Twin size = 300 lbs / 136 kg.” and “Full, Queen, King = 600 lbs / 272 kg.” Its 10-, 16.5- and 20-inch queens all list 600 lb, so on Intex’s figures a king holds no more than a queen.
Bestway lists 330 lb for its 12-inch Tritech twin and 661 lb for its Tritech queen and SleepSupport full.
SoundAsleep prints no weight capacity on the three product pages we read. Our roundup gives its camping queen a 400 lb maximum load, credited to SoundAsleep; we could not find that figure on SoundAsleep’s own pages, so check the box or manual before you buy.

Stay under the printed figure for the specific bed you own, not a figure for its size in general.

Safety

Size names do not make a bed safe for a baby. The US Consumer Product Safety Commission says “Generic twin-, full-, or queen-sized inflatable mattresses are usually intended for adults and older children,” and “Never place infants to sleep on air mattresses or other soft surfaces (such as water beds and adult beds), which are not specifically designed or safe for infant use.” Intex’s owner’s manual warns: “Infants have suffocated on inflatable mattresses. Never place infant aged birth to 15 months to sleep on this inflatable air mattress / air bed. Infants can suffocate on an underinflated or deflated mattress, on bedding, by co-sleeping with another person, and by entrapment between the mattress and bed frame or between the mattress and a vertical surface.”

Will a queen air mattress fit in a 2-, 3-, 4- or 6-person tent?

A tent’s person rating says little about a queen; the floor size decides it.

Top view of a 60 by 80 inch queen air mattress overhanging a 2-person tent floor of 88 by 52 to 42 inches, and fitting inside a 4-person floor of 92 by 90 inches with room to spare — A queen (Intex and Bestway figure) on two makers’ tent floors, to scale.

The table works out the room left around a 60 x 80-inch queen (Intex and Bestway figure) on six makers’ floors. Room left is the tent’s length minus 80 inches and its width minus 60, at floor level.

Tent (maker)	Rated for	Floor, as printed	Room left (worked out)	Maker’s note
Big Agnes Copper Spur UL2	2	88 x 52-42 in	Too narrow by 8 to 18 in	No air-bed note
Kelty Tanglewood 3	3	83 x 68.5 in	3 in long, 8.5 in wide	Peak 45.5 in
Core 4 Person Straight Wall Cabin	4	8 x 7 ft (96 x 84 in)	16 in long, 24 in wide	“Fits 1 Queen”
Big Agnes Bunk House 4	4	92 x 90 in	12 in long, 30 in wide	No air-bed note
Big Agnes Bunk House 6	6	118 x 100 in	38 in long, 40 in wide	No air-bed note
Core 6 Person Straight Wall Cabin	6	10 x 9 ft (120 x 108 in)	40 in long, 48 in wide	“Fits 1 Queen”

What the table shows:

2-person tents: on Big Agnes’s figures, the Copper Spur UL2 floor is 52 inches wide at the head and 42 at the foot, narrower than a 60-inch queen. A twin (38 to 39 inches wide in the chart above) is the size that fits that floor.
3-person tents: the Kelty Tanglewood 3 clears a queen by 3 inches of length at floor level, which is a fit only on paper. Its peak is 45.5 inches, so a 20-inch raised queen would leave at most 25.5 inches above the mattress at the very center (worked out).
4-person tents: this is where a queen starts to fit. Core rates its 8 x 7-foot straight-wall cabin for one queen, and also says that tent is “2 + Gear (Most Comfortable),” so a 4-person tent holds the bed with little left for bags.
6-person tents: both 6-person floors leave more than 3 feet of spare length and of spare width around one queen (worked out).

Wall shape matters as much as floor size. Outafun, which makes air mattresses, writes on its blog that “A straight-wall cabin tent usually handles a queen mattress better than a sharply sloped dome tent with the same person rating.” In a dome, the walls lean in, so the floor measurement is wider than the space at the height of a raised bed. Our guide to types of camping tents shows which shapes have near-vertical walls.

Safety

If a child will sleep in the tent, leave space between the bed and the walls. Intex’s owner’s manual warns: “Children can be entrapped between the inflatable mattress and an adjacent vertical surface. Provide at least a shoulder width space between the inflatable mattress/airbed and adjacent vertical surfaces such as walls, dressers or other objects.”

Check the power source too. Intex’s manual for its Quickfill Plus internal-pump beds says “For indoor household use only.” Intex describes its pump-free Pillow Rest Classic as “perfect for home or outdoor use,” and SoundAsleep sells its Dream Series as “A raised indoor air mattress” but its Camping Series as “An outdoor-ready single-height camping air mattress.” Read the use line for your bed before you pack it.

Will an air mattress fit in a truck bed?

A queen is longer than six of the seven pickup beds below, and on Car and Driver’s Tacoma figure it is wider than the space between the wheel wells. Bed lengths below are the names Car and Driver gives for each truck’s beds, converted to inches; actual floor lengths vary a little, so measure yours.

Truck and bed (Car and Driver)	Length (worked out)	vs an 80-in queen	vs a 75-in Intex twin or full
Toyota Tacoma, 5 ft	60 in	20 in short	15 in short
Toyota Tacoma, 6 ft	72 in	8 in short	3 in short
Ford F-150, 5.5 ft	66 in	14 in short	9 in short
Ram 1500, 5 ft 7 in	67 in	13 in short	8 in short
Ram 1500, 6 ft 4 in	76 in	4 in short	1 in to spare
Ford F-150, 6.5 ft	78 in	2 in short	3 in to spare
Ford F-150, 8 ft	96 in	16 in to spare	21 in to spare

Width is the bigger problem. Car and Driver says “The bed width at the wheel wells falls just short of 45 inches” on the Tacoma, so a 60-inch queen is about 15 inches wider than that gap, and a 54-inch full about 9 (worked out). Truck-bed air mattresses are cut for the gap: Napier, which makes truck tents, makes its Sportz Air Mattress 50 inches wide and says it is “Sized to fit between the wheel wells of most compact or full-size pickup trucks.” Asked whether it covers the wheel wells, Napier answers: “No, the air mattress is designed to fit in between the wheel wells of the truck.”

So, on these figures, a queen lies flat only in a full-size truck with an 8-foot bed, and only if it can sit on or over the wheel wells. In shorter beds, either drop the tailgate to gain length (check your truck’s manual for what the open tailgate is rated to hold) or use a twin or a truck-bed mattress.

How to measure your tent, truck bed or room

Find the maker’s floor figure first

Look up the tent’s floor dimensions or the truck’s bed length on the maker’s page or manual, not the person rating or the bed’s name. They give you a number to check your tape against.

Measure the floor wall to wall, at the floor

In a tent, measure from seam to seam along the floor in both directions. In a truck, measure from the front wall of the bed to the closed tailgate, then the narrowest width, which is usually between the wheel wells.

Measure again at mattress height in a dome tent

Hold the tape at the height of your bed’s top, 10 or 20 inches up, because sloping walls leave less room there than on the floor.

Measure the bed inflated

Intex’s FAQ says: “Make sure the airbed is inflated before it is measured,” and “Make sure to incorporate the bulge on whichever side you are measuring.”

Subtract and leave room

Take the bed’s length and width from the space’s length and width. What is left is your room for bags, a door that opens, and, where a child sleeps, the gap Intex’s manual asks for.

Between two sizes: how to choose

The queen fits only on paper. Choose the smaller size. A full gives up 6 inches of width and 5 of length against a queen on Intex’s and Bestway’s figures (worked out), and that is often what a 3-person tent or tight cabin needs.
The maker’s figure decides it. Two queens are not the same size: SoundAsleep’s camping queen is 2 inches narrower and shorter than Intex’s (worked out). If you are an inch or two short, compare makers’ printed sizes before giving up a size.
One sleeper, a tall one. Rest Right lists a twin XL at 38 by 80 inches, as long as a queen and 22 inches narrower (worked out).
Two sleepers and a small tent. Stay under the printed capacity for both of you together; Intex prints the same 600 lb for its full and queen, so a full can carry what a queen does on its figures.
A truck. Pick a bed made for the wheel-well gap, such as the 50-inch Napier, or a twin.

Cot or air mattress: the size difference

A cot is narrower than most air mattresses but often longer, and it sits up off the floor. Kamp-Rite’s Standard Kwik-Cot sets up at 79 inches long, 29 wide and 19 high, with a “Capacity: 300 lbs.” Its Double Kwik-Cot is 85 by 55 inches with a “Capacity: 500 lbs (total)”: about as wide as a full air mattress but 10 inches longer (worked out). TETON lists its Outfitter XXL cot at 86 by 45 by 19.5 inches. A cot’s legs stand on the tent floor, so the floor still has to fit the cot’s length and width, just as it does for an air mattress.

If you are choosing between something inflatable and something that is not, our comparison of sleeping pads and air mattresses covers weight, packing and warmth.

Frequently Asked Questions

Q. How big is a queen air mattress in feet?

On Intex’s and Bestway’s figures, 5 feet wide by 6 feet 8 inches long (60 by 80 inches). Height depends on the model: the queens charted here run from 9 inches (SoundAsleep’s camping queen) to 20 inches (Intex’s raised queen).

Q. Is a double air mattress the same as a full?

In US listings a “double” usually means a full. Check the inches rather than the name: Intex’s and Bestway’s fulls are 54 by 75 inches.

Q. How much weight can a queen air mattress hold?

Intex lists 600 lb for its queens and Bestway 661 lb for its Tritech queen. That figure covers everyone on the bed together.

Q. Will two queen air mattresses fit in a 6-person tent?

Barely, if at all: two queens side by side need 120 by 80 inches (worked out). Big Agnes’s Bunk House 6 floor is 118 inches long, 2 short, and Core’s 10 x 9-foot cabin matches 120 inches with nothing to spare; Core rates that tent “Fits 1 Queen.”

Q. Does a built-in pump make the mattress bigger?

Not on Intex’s figures: its queens with and without a built-in pump are listed at 60 by 80 inches. Intex’s pump models are its raised 16.5- and 20-inch beds, so they add height, not floor space. A built-in pump also needs an outlet, so check the bed’s indoor or outdoor use line.

Q. Can two people share a twin or full air mattress?

Bestway says its full “comfortably fits up to 2 adults” and its twin “fits 1 adult”; Intex rates its twins at 300 lb.
