In case you haven’t noticed in the table above, most RV mattresses – just like semi-truck mattress sizes – are smaller than traditional mattress sizes. Which makes sense because recreational vehicles are not exactly known for having vast amounts of space.
To save space, most RVs will have custom bunk beds or pull-out beds for you to use. Of course, this will vary depending on the specific design of your RV.
RVs usually give you a small but cozy sleeping area hence the smaller mattress sizes. Moreover, RV mattresses can also come in odd shapes to fit the structure of some campers and RVs. We go into more detail on the most popular RV mattress sizes in the section below.
RV Twin
A RV twin size mattress comes in different dimensions ranging from 28″ x 75″ to 38″ x 80″.
If you’re wondering why there are many twin size variations, it’s simply because RVs are not all the same. It’s usually the width that varies depending on the space in your RV, while the length will often be 75 or 80 inches.
A RV twin mattress is suitable for one person only, which could be a child or an adult with a smaller body type. To choose the right dimensions, make sure to measure the sleeping space in your RV and consider your height so you won’t get a mattress that’s too short.
RV Truck
RV truck size mattresses come in two variations: 35″ x 79″, and 42″ x 80″.
Mostly used in semi-trucks or camper vans, truck-size mattresses can also be used in RVs and campers. This RV mattress size is best suited for taller individuals who are looking for a space-saving option.
RV Bunk
Another RV mattress size that comes in different dimensions, RV bunk mattresses range from 28″ x 72″ to 42″ x 80″.
Always measure the bunk beds in your RV to get the exact dimensions that you need.
Most commonly found in Class C motorhomes, RV bunk beds are great for kids and young adults.
RV Three quarter
RV three quarter mattresses come in 48″ x 75 and 48″ x 80″ dimensions.
You should opt for this mattress if your RV doesn’t have enough space for a full or double bed. A RV three quarter mattress is suitable for one adult, or two kids.
RV Full/Double
A RV full or double mattress measures 53″ x 75″.
It’s just one inch smaller than a regular full mattress and it’s the most popular of all RV mattress sizes. An RV full mattress is ideal for individuals who want extra space to move around and stretch their body.
RV Short Queen
RV short queen mattresses are 60 inches wide and 75 inches long.
As its name suggests, it’s five inches shorter than a regular queen mattress but it has the same width. It’s a great alternative for couples who can’t fit a long mattress into their camper or RV.
RV Queen
The RV queen mattress size is no different than a traditional queen which measures 60″ x 80″.
Thus, you won’t have to look for a mattress that says “RV queen” because you can just get a standard queen mattress. This RV mattress size is best suited for couples who want ample sleeping space which isn’t different from what they would get in a bedroom.
RV King
A RV king size mattress measures 72″ x 80″.
It’s not so commonly used as its the biggest RV mattress size and it takes up a lot of space. Nevertheless, if you have a bigger RV and you want a wider mattress, go ahead and get an RV king mattress. It can comfortably fit average-sized couples and it can also fit a parent with two small kids.
RV mattresses vs. regular mattresses
The two main differences between RV mattresses and regular mattresses are size and thickness.
RV mattress sizes are often smaller and designed to fit in tight, narrow spaces. They are also usually thinner at less than 8 inches thick so you won’t bump into the ceiling of your RV while sitting or getting up.
When it comes to construction, RV mattresses and regular mattresses are pretty much made with the same materials. You can get a memory foam mattress, a latex mattress, and even an innerspring mattress for your RV or camper. And, you can also choose what firmness level you like for your RV mattress.
Below, I compare the dimensions of RV mattresses and regular mattresses. I also mention their benefits and who they’re a good fit for.
Twin
A twin-size mattress measures 38″ x 75″.
It’s the smallest standard mattress size in the US and it’s best for average-sized individuals who don’t have a lot of space. However, if you’re someone who’s a little bit taller, you should opt for a twin XL mattress which has the same width but is five inches longer.
As I mentioned earlier, a RV twin mattress has many variations and dimensions. Some RVs and campers can fit regular twin mattresses, but others will require a smaller bed.
Full
A regular full mattress’s dimensions are 54″ x 75″.
That’s just one inch narrower than an RV full or double bed. Full mattresses are great for individuals who need more room for themselves. But if you sleep with a partner, it’s not the best mattress for couples and we would steer you toward a bigger size, although some brands offer a full XL mattress.
Queen
Regular queen and RV queen mattresses have the same dimensions, 60″ x 80″.
If you have a queen mattress at home, you can also use it in your RV as long as it has enough space for a queen bed. Touted as the best-selling mattress size in the US, queen mattresses are ideal for couples who don’t want to feel cramped up in bed.

King
A regular king size mattress measures 76″ x 80″.
It’s four inches wider than an RV king mattress but they both have the same length. You should get a king mattress if you sleep with a partner and you want something wider than a queen bed. Moreover, a king mattress can accommodate you and your partner plus one child maximum.
If you co-sleep with several children, we recommend getting an oversized bed such as an Texas king or an Alaskan king bed.
California king
Finally, a California king mattress measures 72″ x 84″.
It has the same width as an RV king but it’s four inches longer. If you’re a taller person, this is a great albeit expensive option for you to have some more legroom. California king beds are also suitable for couples who want a longer mattress, but it is a bit smaller than a king-size mattress.
FAQs
Yes, you can cut an RV mattress to fit your RV as long as it’s made entirely out of foam.
