What Size Air Mattress Fits in a Truck Bed?
The size of an air mattress that fits in a pickup truck bed depends primarily on the bed length and whether you choose a standard home air mattress or a dedicated custom-molded truck bed air mattress. For long 8-foot truck beds, a standard Twin (38x75 in) or Full (54x75 in) mattress fits flat between the wheel wells, while an 8-foot bed can accommodate a standard Queen (60x80 in) only if resting above the wheel wells. For standard 6.5-foot and short 5.5-foot beds, standard mattresses bunch awkwardly. Consequently, truck campers overwhelmingly choose custom truck bed air mattresses (such as AirBedz or Rightline Gear) featuring integrated side cutouts that contour perfectly around the protruding wheel wells.
Truck Bed Dimensions vs Standard Mattress Sizing
To understand why fitting an air mattress into a truck bed requires careful measurement, one must examine truck bed geometry. Pickup truck beds are divided into three standard length categories: short beds (typically 5.5 to 5.8 feet on crew-cab half-ton trucks), standard beds (6.5 feet on extended cabs and work trucks), and long beds (8.0 feet on heavy-duty and commercial pickups).
However, the greatest physical obstacle is not length, but width. The interior sidewall width of a standard full-size pickup bed measures roughly 60 to 65 inches. But between the wheel wells, width constricts sharply to exactly forty-eight to fifty inches. A standard home Queen air mattress measures 60 inches wide by 80 inches long. If you drop a standard Queen into a truck bed, the mattress cannot lay flat; it wedges tightly between the wheel wells, buckling violently upward in the center and leaving an unusable, rolling ridge that makes sleeping impossible.
Compare standard residential mattress dimensions against common truck bed dimensions:
| Mattress Size / Bed Category | Width x Length Dimensions | Fits Between Wheel Wells (48-50 in)? | Tailgate Closed Feasibility | Sleeping Comfort Rating |
|---|---|---|---|---|
| Standard Twin Mattress | 38 in W x 75 in L | Yes (Fits flat between wheel wells easily) | Closes on 6.5 ft & 8.0 ft beds; open on 5.5 ft | Comfortable for 1 solo camper |
| Standard Full / Double | 54 in W x 75 in L | No (Slight pinch across 48 in wheel wells) | Closes on 6.5 ft & 8.0 ft beds; tight fit | Cozy for 2 small adults; slight edge lift |
| Standard Queen Mattress | 60 in W x 80 in L | No (Wedges 10-12 inches too wide) | Requires 8-foot bed or open tailgate | Severe center buckling unless above wheel wells |
| Dedicated Full-Size Short Bed (5.5 ft) | Custom 60 in W x 68 in L (Wheel cutouts) | Yes (Custom cutouts wrap around wells) | Closes fully on 5.5 to 5.8 ft beds | Optimal tailored comfort for 2 adults |
| Dedicated Full-Size Standard (6.5 ft) | Custom 60 in W x 76 in L (Wheel cutouts) | Yes (Custom cutouts wrap around wells) | Closes fully on 6.5 ft beds | Luxurious full-width sleep for 2 adults |
| Mid-Size Truck Custom (Tacoma/Colorado) | Custom 54 in W x 60-72 in L | Yes (Engineered for narrow 40-42 in wells) | Fits 5 ft short bed or 6 ft long bed | Perfect custom fit for mid-size trucks |
Dedicated Truck Air Mattresses: The AirBedz Cutout Advantage
Because standard home mattresses fit so poorly inside truck boxes, outdoor gear manufacturers developed specialized truck bed air mattresses, pioneered by brands like Pittman Outdoors AirBedz. The revolutionary design innovation of these dedicated mattresses is integrated wheel well cutouts. Heavy-duty puncture-resistant PVC or TPU fabric is molded with indented pockets on each side that slide directly over the protruding steel wheel wells.
By hugging the contours of the wheel wells, a dedicated truck air mattress utilizes the full width of the truck bed—from exterior wall to exterior wall (measuring roughly 60 to 64 inches across). This expands usable sleeping surface area by nearly thirty percent, allowing two full-grown adults to sleep comfortably side-by-side with plenty of elbow room. Furthermore, many models include inflatable insert pillows that fill the wheel cutouts, converting the truck mattress back into a standard rectangular air bed for home guest room use.

Tailgate Solutions for Short 5.5-Foot Truck Beds
The single most common challenge in modern truck camping is the prevalence of short 5.5-foot (66-inch) beds on modern four-door crew-cab trucks. Because an average adult human measures between 68 and 72 inches tall, sleeping flat in a 66-inch bed with the tailgate closed forces you into a cramped fetal position. To solve this spatial limitation, truck campers utilize the tailgate as an extended sleeping platform.
Lowering the tailgate adds eighteen to twenty-four inches of flat, reinforced horizontal space, expanding the usable bed floor from 5.5 feet to a generous 7.0 to 7.5 feet. AirBedz and Rightline Gear manufacture specialized short-bed mattresses with optional tailgate extension air pads that cover the lowered tailgate completely. To protect campers from rain and mosquitoes when camping with the tailgate open, campers pair the mattress with a fitted truck bed tent that wraps securely around the open tailgate lip.
Examine camping setups based on truck bed lengths and tailgate positions:
| Truck Bed Length | Tailgate Position During Sleep | Effective Mattress Length | Recommended Camper Protection |
|---|---|---|---|
| 8.0-Foot Long Bed | Tailgate Closed Fully | 80 to 96 Inches (Full length) | Standard fiberglass camper shell or tonneau |
| 6.5-Foot Standard Bed | Tailgate Closed Fully (Adults ≤ 6'2") | 76 to 78 Inches flat length | Fitted truck bed tent or standard truck cap |
| 5.5-Foot Short Bed (Tailgate Closed) | Tailgate Closed (Cramped angle) | 60 to 64 Inches max length | Only suitable for children or diagonal solo sleeping |
| 5.5-Foot Short Bed (Tailgate Open) | Tailgate Dropped Flat Open | 82 to 88 Inches extended length | Truck bed tent with extended tailgate vestibule |
How to Measure and Set Up an Air Mattress in Your Truck Bed
Follow these five camping steps to measure your truck bed and inflate your mattress for a comfortable night outdoors.
Measure Length with Tailgate Closed and Open
Measure from the inside front bulkhead to the closed tailgate, then lower the tailgate and measure to the outer edge.
Measure Width Between the Wheel Wells
Measure the narrowest horizontal span between the inner wheel humps (typically 48 to 50 inches on full-size trucks).
Sweep Bed Clean and Lay Down Moving Blanket
Sweep away all gravel and grit, laying a heavy moving blanket or tarp on the bed floor to protect the air mattress from punctures.
Align Wheel Well Cutouts and Inflate Mattress
Unfold the dedicated truck mattress, seat the cutout pockets over the wheel wells, and turn on the built-in 12V rechargeable pump.
Fit with Deep-Pocket Sheets and Sleeping Bags
Dress the mattress with a fitted queen sheet and heavy cold-weather sleeping bags for a warm, comfortable night under the stars.
Frequently Asked Questions (8 Questions Answered)
Q1: Can a regular queen air mattress fit in a truck bed?
A standard Queen is 60 inches wide and will not fit flat between the 48-50 inch wheel wells; it will buckle unless supported above the wells.
Q2: What size air mattress fits in a 6.5-foot truck bed?
A standard Twin fits flat between the wells, but a custom 6.5-foot truck mattress with wheel cutouts (60x76 in) fits best, utilizing the full width.
Q3: What size air mattress fits in a 5.5-foot truck bed?
A custom 5.5-foot short-bed truck mattress with wheel cutouts fits best; campers typically lower the tailgate and use a truck tent for full legroom.
Q4: Can you sleep in a 5.5-foot truck bed with the tailgate closed?
Only if you are under 5 feet 5 inches tall or sleep diagonally across the bed; adults over 5'6" will find a closed 5.5-foot bed too short.
Q5: What is an AirBedz mattress?
AirBedz is a dedicated truck bed air mattress featuring patented side cutouts that fit around truck wheel wells, utilizing the full width of the bed.
Q6: How do you power the pump for a truck air mattress?
Most dedicated truck air mattresses feature a built-in rechargeable NiMH battery or include a 12-volt DC cord that plugs into your truck cigarette lighter.
Q7: Will a truck air mattress get punctured by spray-in bedliners?
Rough spray-in bedliners can abrade PVC over time; always lay down a moving blanket, canvas tarp, or foam gym mat beneath the air mattress.
Q8: Can two people sleep on a truck bed air mattress?
Yes, dedicated full-size truck air mattresses are 60 inches wide (the same width as a Queen bed), easily accommodating two adults.
