What Size Mattress Fits in a Truck Bed?

Size is a crucial consideration when selecting a mattress for your truck bed. Since most truck beds are between six and eight feet long, you must find a mattress that fits within those dimensions. Several mattress sizes will fit in a truck bed, but the most common options are twin, full, and queen. Remember that a twin mattress is the smallest option and will usually only be comfortable for one person.

A full mattress is slightly larger and can comfortably sleep two people. A queen mattress is the largest option and can comfortably sleep three people. It’s essential to consider how many people will be using the mattress and how much space you have in your truck bed when choosing a size.

If you have a large truck bed and plan on using the mattress for multiple people, then a queen mattress would be the best option. However, if you have a smaller truck bed or only plan on using the mattress for one person, then a twin or full mattress would be better. Whatever size you choose, measure your truck bed before purchasing to ensure the mattress will fit.

In case you already have a mattress that doesn’t fit in your truck bed, here are two tips on how to make it work:

Try placing the mattress lengthwise instead of widthwise. This will give you more room to maneuver and make getting the mattress into the bed easier.

If the mattress is too long, try cutting it down to size. This is a more drastic measure but it can be done if you’re desperate. If all else fails, you can always sleep in the cab of your truck! Just make sure to bring a pillow and blanket to be comfortable.


What Is the Standard Size Bed for a Truck?

Suppose you’re considering purchasing a truck bed. In that case, one of the first questions you must answer is what size bed you need. The standard size for a truck bed is 8 feet long and 5 feet wide. However, you may also find beds that are 6 feet long and 4 feet wide or 10 feet long and 6 feet wide. Remember that the dimensions of a truck bed can vary depending on the make and model of the truck. For example, a Ford F-150 has a different bed size than a Chevy Silverado. When in doubt, always check with the manufacturer before making a purchase.

Will a King Size Mattress Fit in a Truck Bed?

If you’ve ever considered making your truck bed more comfortable using a king-size mattress, the answer is yes; it will fit in most truck beds, but only if placed in a slanting position. This means that one side of the mattress will be higher than the other, which may only be comfortable for some. If you plan on using the mattress for multiple people, we recommend choosing a queen-size mattress. Remember that a king-size mattress is more challenging to move and maneuver, so consider this when deciding.

How Do You Transport a Mattress in a Truck?

Transporting a mattress in a truck can be challenging, but taking a few precautions can help ensure it arrives at its destination without damage:

  1. Take measurements of the mattress and the truck to ensure the mattress will fit.
  2. Clean the mattress to remove any dirt or debris that could cause stains. Once the mattress is clean, wrap it in plastic or place it in a particular mattress bag to protect it from moisture.
  3. Load the mattress into the truck and secure it using straps or rope.

With careful planning, you can transport your mattress safely and without damage.

How to Determine Your Truck Bed Size

Truck owners’ most common question is how to measure their truck bed. To get started, you need to know your truck’s dimensions. The easiest way to find them is by searching for your truck’s make, model, and year online. Once you have the measurements, you can measure your truck bed. Remember that there are different truck bed sizes, so you must also consider that.

You can quickly determine your truck bed size using a steel tape measure to measure the length and width of the bed from the inside of the bed rails. The most common truck bed sizes are:

Length: 80 inches (2032 mm)

Width: 60 inches (1524 mm)

Height: 14–17 inches (355–432 mm)

Remember that these measurements may vary depending on your truck’s make and model. If you need clarification about your bed size, consult the owner’s manual or contact the manufacturer.

How Wide is a Full-Size Truck Bed?

A full-size truck bed is typically between six and seven feet wide. However, there may be some variation between different truck models. For example, a Ford F-150 is six and a half feet wide, while the bed of a Chevy Silverado is seven feet wide. The bed’s width is crucial when selecting a truck, as it determines the cargo the truck can carry.

Suppose you need to transport large items or loads of materials regularly. In that case, you should choose a truck with a broader bed. On the other hand, if you only need to transport large items occasionally, a narrower bed may be sufficient. Ultimately, testing different trucks and assessing which bed width suits your needs is the best way to determine the correct size.

Can a Mattress Fly Out of a Truck?

You may wonder whether a mattress can fly out of the back of a truck, especially if you’ve seen a mattress on a truck bed. The answer is yes, but it’s more complex than it seems. For a mattress to fly out of a truck, the truck must be moving fast enough, and the mattress must be positioned just the right way. If the mattress lies flat against the truck floor, it will likely stay in place.

However, if the mattress is leaning against the side of the truck or protruding from the back, it is more vulnerable to becoming airborne. The speed of the truck is also a factor. At lower speeds, there’s less force acting on the mattress, making it less likely to fly out. But at higher speeds, wind resistance increases, providing enough force to dislodge even a heavy mattress.


Determining the mattress size that fits your truck bed is essential for anyone planning to transport a mattress. Loading and securing the mattress properly in the truck are also crucial to prevent damage during transport. However, truck beds can serve other purposes, such as sleeping, particularly during camping. Therefore, determining the size of the mattress that fits in a truck bed is also essential for anyone who plans on using their truck bed as a makeshift bedroom. Proper planning ensures that your mattress fits snugly in your truck bed, allowing you to enjoy a comfortable night’s sleep no matter where you are.
