So you are looking for what size mattress fits in a truck bed? The short answer depends on your truck bed mattress size, model, and layout. Whether you need to transport belongings or sleep comfortably, understanding dimensions is crucial.
Most short beds fit Twin or Full mattresses flat, while long beds may handle Queen sizes. For the best fit, measure your truck bed dimensions, especially around wheel wells and bed rails. You’ll need to consider whether a queen-size mattress or queen box spring will fit inside with the tailgate closed.
Some popular solutions include RV mattress sizes, air mattresses with wheel well cutouts, and custom foam mattress options. Whether you’re planning to haul a new mattress home, deliver one, or build a cozy truck camping setup in your pickup truck, you’ll find the ideal fit here. Let’s dive in!
Understanding Truck Bed Sizes & Variations
Before choosing a mattress, you must know your truck bed dimensions by model. Not all truck beds are the same length or width. Sizes vary by brand, year, and cab style. A crew cab may have a shorter bed than a regular cab, even on the same model.
Also, take note of the wheel wells’ clearance. These cut into the flat bed space and can affect the mattress width. Even if a mattress is the right length, the width may not fit flat between the wheel wells. The location of these wheels matters when you carry or load a mattress.
Pro tip: Always measure from the inside of the tail gate to the cab wall. Don’t forget to factor in the tailgate utilization if you plan to sleep with it down for extra length. Some guys prefer to leave the tailgate open for those extra inches when they sleep or transport mattresses.
Here’s a quick look at common bed sizes:
| Truck Model | Short Bed (Length) | Standard Bed (Length) | Long Bed (Length) |
| Ford F-150 | 5.5 ft | 6.5 ft | 8 ft |
| Chevy Silverado | 5.8 ft | 6.6 ft | 8.2 ft |
| Ram 1500 | 5.7 ft | 6.4 ft | 8 ft |
| Toyota Tacoma | 5 ft | 6 ft | – |
| GMC Sierra 1500 | 5.8 ft | 6.6 ft | 8.2 ft |
| Nissan Frontier | 5 ft | 6 ft | – |
Standard Mattress Sizes vs. Truck Bed Compatibility
Now that you know your truck bed dimensions, it’s time to match them with standard mattress sizes. But keep in mind that mattresses are designed for bedrooms, not truck beds. So, fit may not always be perfect, especially with wheel well spacing in the way. When you haul or deliver a queen mattress, these factors become even more important.
Twin / Twin XL
Twin mattresses (38″ x 75″) fit most short bed pickups and lay flat without issues. Twin XL (38″ x 80″) works well for longer short beds like on a Chevy Silverado or Ram 1500. Best for solo sleepers and easy to fit between wheel wells. You can secure with tie downs or ratchet straps for transport.
Full / Full XL
Full (54″ x 75″) and Full XL (54″ x 80″) are good for standard beds, especially in trucks with no wheel well intrusion (or with a platform above the wells). They offer more space than a Twin but may need trimming or custom cuts if your bed narrows toward the cab. Use plywood as a base if needed to protect the foam.
King / Queen Size Mattress
Will a queen-size mattress fit in a 6.5′ truck bed? Yes, if you leave the tailgate down, but only width-wise (60″). It’s tight and may require a wheel well cutout. King mattresses are almost always too big unless you’re customizing a long, flatbed, or platform setup. When you transport a queen box spring with the mattress, the space becomes even tighter.
Wheel Well Challenge
Most truck beds are narrow between the wheel wells. Measure this area carefully, it’s usually around 38–42″. Even if a mattress fits the bed’s full width, it may not squeeze between the wheel wells without trimming. Some people use rope or duct tape to compress the mattress temporarily, but this isn’t ideal for foam.
If you’re serious about comfort, consider RV-sized mattresses. They come in narrower widths for sleeper cab compatibility and truck camping comfort. The dimensions work better with standard pickup truck layouts. Commercial drivers should note that semi-truck mattress dimensions differ significantly from those of pickup beds, especially in terms of length requirements and cab configurations.
Top Mattress Types for Truck Beds
Choosing the right mattress for your truck means balancing comfort, fit, and function. Some materials handle cold nights, others pack down better. Whether you need to load it frequently or keep it in place, material matters. Let’s explore the most popular mattress types for 2025.
Memory Foam
Memory foam is one of the popular ones. It molds to your body and offers excellent truck camping comfort. It’s great for pressure relief, but can trap heat or stiffen in cold climates. A foam mattress can be easier to secure with straps compared to spring models. For a comparison of the current top-rated truck bed mattresses, including specialized foam options, see our detailed guide.
Pros:
- Soft, supportive sleep
- Can be trimmed for wheel wells
- Works well with cooling mattress toppers
- Easier to tie down without damage
Cons:
- Heavier to lift and carry
- Susceptible to cold-weather performance issues
- Can collect dirt if not protected
Top Pick: Amerisleep AS3. It’s eco-friendly, breathable, and has RV-size options available.
Hybrid Mattresses
Hybrid models combine foam and coils. They’re great for airflow and bounce and often meet FMVSS 302 safety standards for flame resistance. These work fine in a pickup truck bed but require careful lifting to avoid damage.
Pros:
- Better support for back sleepers
- Available in many RV mattress sizes
- Maintains shape in good condition
Cons:
- Bulkier than foam-only options
- Not ideal for ultra-compact truck setups
- Heavier weight makes them harder to pull out
Top Pick: Dreamfoam Hybrid. It’s budget-friendly, cooling gel, medium-firm feel, and available in short queen.
Air Mattresses
Airbeds are ideal for temporary setups. They pack small and can inflate when needed, perfect for overland campers or hunters. You can dump the air and store it in your garage when not in use.
Pros:
- Portable and lightweight
- Easy to deflate and store
- Can sit in the seat when deflated
Cons:
- Can lose air overnight
- Not ideal in very cold or hot conditions
- May need duct tape for emergency repairs
Top Pick: AirBedz Pro3. It has a built-in pump, fits over wheel wells, and has a 1,000-lb capacity.
Custom King or Queen Mattresses: When to Consider Them
Sometimes, standard sizes just don’t fit flat in your truck bed. That’s when a custom semi truck mattress becomes the perfect solution. If your truck bed has unique dimensions, wheel well cutouts, or a built-in platform with bed rails, custom sizing is worth it.
Ideal For
- Trucks with built-in storage or odd shapes
- Campers with tailgate extenders or toolboxes
- Drivers who want an exact fit and maximum comfort
- Those with trailer or van conversions
Sizing Process
Measure length, width, and wheel well spacing at the exact location. Then share your specs with a local or online mattress builder. Many offer templates to guide you. Watch a video tutorial if available to ensure accuracy.
Material Options
- Memory foam (easy to cut to size)
- Latex (durable and naturally cooling)
- Cooling gel hybrids
- Fire-retardant builds (meets FMVSS 302 safety)
Cost
Prices start around $300 for basic builds. Higher-end custom truck mattresses can run $800+, especially with advanced cooling or orthopedic layers. Consider if you need matching sheet sets, too.
When standard just won’t do, go custom. Search terms like “custom truck mattress near me” can help you locate local makers or RV mattress builders who understand pickup truck needs.
How to Measure Your Truck Bed for a Mattress
Getting the right fit starts with precise measurements. Use a tape measure to record the truck bed length, width, and wheel well spacing. This ensures your mattress will lie properly without issues.
Steps you can follow:
- Measure from the tail gate to the cab (inside the bed)
- Measure between the wheel wells for width
- Note the height to the top of the bed rails
- If you use a platform or bed liner, subtract that from the vertical space
- Consider tailgate use. An open tailgate may allow for a longer mattress
- Check at an angle for diagonal placement options
These numbers help you pick or build a mattress that won’t bunch up or slide. Some use foam mattresses with cutouts or DIY camper mattress plans to match tricky spaces. Always double-check sizing before ordering! Pull out your measuring tape at multiple points since truck beds aren’t always perfectly square.
Pro Tips for Comfort & Safety
Sleeping in a truck bed doesn’t have to mean sacrificing comfort. A few smart upgrades can turn your space into a cozy, safe sleep zone. Whether you’re at home in your garage or out camping, these tips help.
Cooling Hacks
Memory foam holds heat. Try a cooling gel topper or breathable sheets. For summer trips, store your mattress in a shaded spot during the day. Protect it from direct sunlight to maintain its good shape.
Safety First
Choose fire-resistant models that meet FMVSS 302 mattress safety standards. These materials slow flame spread in emergencies, making them a must for enclosed sleepers. Secure it with proper tie-downs, not just rope or duct tape.
Storage Smarts
Use roll-up or tri-fold mattresses. They save space when not in use. Vacuum-seal bags work well for thin foam beds. Store them standing on their side with legs or supports if needed.
Budget Fixes
For a quick upgrade, try a truck bed mattress topper solution. Even a 2-inch pad improves comfort. Combine with a DIY base like plywood for better support. This is fine for occasional use and costs less.
Some more tips
- Add anti-slip pads to keep the mattress from sliding
- Use a bug screen if sleeping under an open canopy
- Try modular cushions for odd-shaped beds
- Keep gear organized so nothing damages the mattress
- Use a sheet or cover to protect from dirt

Creative Solutions for Small/Non-Standard Beds
If your truck bed is under 6 feet, don’t worry, you still have smart options. Many campers with 5-foot or 5.5-foot beds make it work using creative tricks and compact setups. Even with a short bed, you can sleep well or transport mattresses effectively.
Short Beds (5–5.5 ft)
For compact pickups like the Ford Ranger or Toyota Tacoma, full-size mattresses won’t fit inside with the tailgate closed. Try using a foldable tri-fold mattress, or cut down a Full XL foam mattress to size. Some brands offer short RV mattress sizes that fit snugly between wheel wells. You might need to sit at an angle or use creative positioning.
Modular Designs
Use modular pads or folding mattress panels that stack during travel. These are easy to store and adjust based on available space. Many DIY campers love this style for flexibility and cost savings. They’re easier to lift and carry, too.
Topper Trick
If you already have a thin pad or bench, just add a mattress topper for comfort. Look for cooling foam toppers or gel options for warm nights. This trick works well if space is limited, but comfort is a must. Secure with tie downs to prevent sliding.
Other Budget DIY Ideas
Some use puzzle foam floor mats beneath a 3-inch topper for a cheap base. You can also try stacking sleeping pads or yoga mats in layers. Combine with a mattress protector to keep everything dry and clean. Watch online video guides for more creative solutions.
So even if your truck is small, your sleep doesn’t have to suffer. With the right approach, you can make any pickup truck bed comfortable.
Frequently Asked Questions
Will a queen mattress fit in a 6.5′ truck bed?
A queen mattress is 80 inches long, which is just over 6.5 feet. It might fit if you lower or remove the tailgate. However, width and wheel well clearance often make it a tight squeeze. The same length issue applies to a queen box spring.
Do memory foam mattresses get too cold for winter camping?
Yes, memory foam can become stiff in cold weather. This affects comfort and support. Using a cooling gel topper or an insulated mattress cover can help regulate temperature. Store inside when possible to maintain good shape.
What’s the most common semi-truck mattress size?
The most common size is around 36″ wide and 75″ long, similar to a twin XL. This fits most sleeper cabs comfortably. Custom sizes are also popular for specific truck models and unique bed rail configurations.
Can I use a regular mattress in my truck?
Regular mattresses are usually too big or thick for truck beds. They also lack cutouts for wheel wells. It’s better to use truck bed mattresses or custom-sized foam mattress options for the best fit. You’ll struggle to tie them down properly.
How do I stop my mattress from sliding in the truck bed?
Use non-slip mats or rubber pads under the mattress. You can also strap it down using cargo nets, ratchet straps, or tie downs. Keeping the mattress snug against the cab and tailgate helps reduce movement. Never use just rope or duct tape alone.
Are truck bed mattresses waterproof?
Many truck bed mattresses have waterproof covers or come with waterproof protectors. Still, adding an extra waterproof layer is a good idea for longer trips. This protects from rain and dirt during transport.
What thickness is ideal for truck bed mattresses?
Most truck bed mattresses are between 4 and 6 inches thick. Thicker mattresses offer more comfort but can reduce storage space. Consider your comfort needs and bed height when choosing thickness. It is too thick and won’t fit flat under a tonnea
Conclusion
Knowing what size mattress fits in a truck bed is really important before you buy one. Whether you have a short bed or a long bed, choosing the right mattress size and type makes all the difference. From queen-size mattress options to custom foam solutions, there’s something for every pickup truck.
With options like memory foam, hybrid, air, or custom mattresses, you can find comfort tailored to your truck’s space and your needs. Remember to measure carefully around wheel wells and bed rails. Consider if you need to transport with a box spring or just the mattress alone.
Hope this guide will help you measure carefully and pick smart. Whether you’re using ratchet straps to secure for transport or creating a permanent sleep setup, the right mattress transforms your truck bed. Enjoy better rest on every trip!
