What Size Mattress Fits in a Truck Bed?

Types of Truck Beds

There are three types of truck beds: short bed, long bed, and extra-long bed. The truck bed size will determine what size mattress will fit. For example, a short bed is usually six and a half feet long, which means that a twin mattress will fit perfectly. A long bed is usually eight feet long, which means that a full or queen mattress will fit. An extra-long bed is usually nine or ten feet long, which means that a king mattress will fit.

Short Bed

A short bed is defined as a truck bed that is less than six and a half feet long. Most beds in this category are around six feet long. While there are some that are five and a half or five feet long, these are less common. Short beds usually have an interior width of around 50 inches. This gives you enough room to lie down comfortably, but not much more beyond that. If you’re looking for a little extra space, you might want to consider a medium bed instead.

Trucks with short beds are typically used for work purposes. They’re perfect for hauling lumber, dirt, or other materials. They can also be used for camping or other outdoor activities, but you’ll likely be limited in terms of what you can bring with you.

Long Bed

The long bed is the biggest of the three mattress sizes available for pickup trucks. It measures 8 feet long and is ideal for those who frequently haul large items or need extra space for sleeping comfortably. A long bed also gives you more options when it comes to towing, as you can attach a larger trailer or camper without issue.

Extra Long Bed

The extra long bed — often called the “long bed” — is the longest of the truck beds and measures in at 8 feet. These beds are typically found on heavy duty trucks, such as the Chevrolet Silverado 3500 HD, Ford F-350 and RAM 3500. If you frequently haul large loads or need extra space for gear, an extra long bed is a good option.

Mattress Sizes

A mattress is an important piece of furniture to have in your home. It’s not only comfortable, but it also provides support for your body while you sleep. There are many different sizes of mattresses available on the market, so how do you know which one is right for you? In this article, we’ll be discussing the different mattress sizes and what size mattress fits in a truck bed.


A twin mattress is the smallest mattress size available. It’s idea for kids or for adults who are 5 feet 2 inches or shorter. A twin mattress is also a good choice if you need an extra bed for guests but don’t have a lot of space. You can find twin mattresses that are 39 inches wide and 75 inches long, or you can find a twin XL, which is slightly longer at 80 inches.


A full mattress is 54 inches wide and 75 inches long. This size mattress is also known as a “double” mattress. A full size mattress is a good choice for one person who wants plenty of room to spread out, or two people who don’t mind snuggling close together.


Dimensions for a queen size mattress are 60″ x 80″. A queen mattress is large enough to comfortably accommodate two people and is the most popular mattress size among couples. If you have a limited amount of space in your bedroom, a queen mattress is a good compromise between getting a good night’s sleep and having enough room to move around.


A king size mattress is 76 inches wide and 80 inches long, making it the largest mattress size commercially available. This size is also referred to as an “Eastern king” because it is the most popular choice on the East Coast of the United States. However, it is becoming more popular nationwide. A king size mattress is ideal for couples who want ample personal space while sleeping, or for people who have pets or children who often sleep in the bed with them.

Mattress Dimensions

Truck beds come in different sizes, which can make it difficult to decide on the right mattress size. However, there are some standard mattress sizes that will fit most truck beds. These include twin, full, queen, and king. Let’s take a look at the dimensions of each of these mattress sizes.

Short Bed

A short bed mattress is designed to fit in the smaller truck beds that are becoming increasingly popular. These mattresses are typically between 74 and 79 inches long, which leaves enough room for most people to sleep comfortably. However, if you are taller than average, you may want to consider a different size mattress.

Long Bed

A long bed truck is typically 8 feet long, but can vary between different models.The most common mattress size for a long bed truck is a queen mattress, which is 60 inches wide by 80 inches long. However, other mattress sizes such as full, king, and California king can also fit in a long bed truck. For example, a full mattress is 54 inches wide by 75 inches long, while a king mattress is 76 inches wide by 80 inches long. If you have a specific mattress size in mind for your truck, it’s best to measure the dimensions of your truck’s bed to ensure that the mattress will fit properly.

Extra Long Bed

An extra-long or extended cab truck bed is typically 84” long. The most common mattress size for this type of truck bed is a full-size mattress, which is 54” wide and 75” long. Full-size mattresses will fit in an extra-long truck bed with about 30” of length to spare. If you need a little more room to move around or if you just want a little more space to yourself, you can also opt for a queen-size mattress. Queen-size mattresses are 60” wide and 80” long, so they will fit in an extra-long truck bed with about 24” of length to spare.

Truck Bed Mattress Comparison

A mattress for a truck bed is not the same size as a regular mattress. A truck bed mattress is bigger in order to fit the larger size of a truck bed. There are a few options when it comes to finding a truck bed mattress. You can find one that is the same size as your truck bed, or you can find one that is smaller.

Short Bed vs. Long Bed

When choosing a mattress for your truck, you need to know whether you have a short bed or long bed. Truck beds come in two sizes: short beds are typically between 5.5 and 6.5 feet long, while long beds are usually between 7 and 8 feet long. If you’re not sure which size mattress you need, measure your truck bed from end to end to be sure.

Short bed mattresses are typically smaller in width than long bed mattresses, so they may not fit as securely in the bed. You may need to use straps or other methods to keep the mattress in place while you’re driving. Long bed mattresses typically have a higher weight capacity than short bed mattresses, so they can accommodate more people or heavier items.

Long Bed vs. Extra Long Bed

When it comes to truck bed mattresses, there are two main types: long bed and extra long bed. Both types have their pros and cons, so it’s important to know which one is right for you before making a purchase.

Long beds are the most common type of truck bed mattress. They’re typically between six and seven feet long, which is enough to comfortably fit two people. Long beds are great for couples or families who want to sleep in the same bed, but they’re not ideal for taller people because they might not be able to stretch out fully.

Extra long beds are just that: extra long. They’re usually around eight feet long, which gives taller people the ability to stretch out and sleep comfortably. However, extra long beds are less common than long beds, so they might be harder to find and more expensive.


A truck bed is a great place to store a mattress, whether you’re planning to use it for camping or as an extra bed for guests. But what size mattress will fit in a truck bed?

The answer depends on the size of your truck bed. For example, a full-size truck bed will fit a twin-size mattress, while a mid-size truck bed will fit a full-size mattress.

To be sure your mattress will fit in your truck bed, measure the length and width of your mattress and compare it to the dimensions of your truck bed. If you’re still not sure, ask a sales associate at your local mattress store for help.
