Choosing the right mattress size for your camper trailer is more important than you might think. After all, the quality of your sleep can significantly affect your overall camping experience. But with so many options out there, finding the right camper trailer mattress sizes for your RV can be overwhelming. Whether you're looking to replace an old mattress or are outfitting your RV for the first time, this guide will help you choose the best option to ensure a comfortable night’s sleep on the road.
Camper Trailer Mattress Sizes
When it comes to camper trailer mattress sizes, there are several types to choose from depending on your RV’s layout and the kind of sleeping experience you want. The right size will make your sleep more comfortable and your RV space more functional. Here’s a look at the most common mattress sizes:
| Mattress Type | Dimensions (inches) |
|---|---|
| RV Twin Size Mattress | 38 x 75 |
| Truck Size Mattress | 39 x 75 |
| Bunk Size Mattress | 28 x 75 |
| RV Three Quarter Size Mattress | 48 x 75 |
| RV Full or Double Size Mattress | 54 x 75 |
| RV Short Queen Size Mattress | 60 x 74 |
| RV Queen Size Mattress | 60 x 80 |

The right mattress size will depend on the space available in your RV and how much room you need to sleep comfortably. For example, RV queen mattress sizes are a popular choice because they strike a good balance between comfort and space. However, smaller options like the RV truck size mattress might work better for tight spaces.

How to Accurately Measure Your RV Mattress Size
Before purchasing a new mattress, you’ll need to measure your RV bed to ensure a perfect fit. Here’s a quick guide on how to measure the size of your RV mattress:
- Measure the Length: Start by measuring the length of the bed from the headboard or wall to the foot of the bed. Make sure to measure along the floor to account for any curves or slants in the area.
- Measure the Width: Measure the width from one side of the bed to the other, paying attention to the widest point.
- Check the Depth: If you’re upgrading to a thicker mattress, the depth is important to ensure it fits comfortably within your bed frame.
- Account for Extra Space: It's always a good idea to leave a small gap around the mattress for ease of movement, especially if your bed frame has built-in support.
By following these steps, you'll be able to choose the right camper mattress that fits perfectly in your RV.

Common Types of RV Mattresses
Not all RV mattresses are created equal. Depending on your comfort preferences and needs, you may want a specific type of mattress. Here are four popular choices to consider:
Memory Foam Mattresses
Memory foam mattresses are loved for their ability to mold to your body’s shape, providing excellent support and comfort. These mattresses help relieve pressure points, making them a great option for those who prioritize comfort while sleeping. Additionally, memory foam is durable and tends to last longer than other materials, making it a solid investment for your camper.
Innerspring Mattresses
Innerspring mattresses are a more traditional option and are often chosen for their firmness and bounce. They are made with coils that provide a supportive sleeping surface, and they tend to be more affordable compared to memory foam. While they’re not as popular in RVs as memory foam, they can still offer a good night’s sleep and are often lighter than foam mattresses.
Hybrid Mattresses
Hybrid mattresses combine the benefits of both memory foam and innerspring coils. These mattresses are designed to give you the best of both worlds: the comfort of foam and the support of coils. Hybrid mattresses are becoming more popular in RVs because they offer durability, support, and a balance of comfort, making them a great option for long trips.
Latex Mattresses
Latex mattresses are known for their durability, comfort, and eco-friendliness. Made from natural or synthetic latex, these mattresses offer great support and are resilient, meaning they won’t sag over time. If you're eco-conscious and want a mattress that provides firm support, a latex mattress could be a great fit for your RV.

Differences Between an RV Mattress and a Regular Mattress
Understanding the key differences between an RV mattress and a regular mattress can help you make a more informed decision when shopping for your camper. Here’s a quick rundown of what sets them apart:
- Size: RV mattresses come in custom sizes, which are typically smaller than regular mattresses. For instance, the camper queen mattress size is usually smaller than a standard queen mattress, so be sure to measure your space before purchasing.
- Weight: RV mattresses are designed to be lighter than traditional mattresses, which is important when considering your RV's weight capacity. A lighter mattress will reduce the overall weight of your RV, helping with fuel efficiency.
- Design: RV mattresses are built to withstand the constant movement of travel. While regular mattresses are designed for stationary use, RV mattresses are crafted to hold up to the shifting and vibrations of the road.
- Cost: RV mattresses tend to be more affordable than regular mattresses. They are specifically designed to be durable and functional in the mobile environment, so they often come with fewer luxury features than a regular mattress.

Can You Use a Regular Mattress in an RV?
While it's technically possible to use a regular mattress in your RV, it’s not the best choice for most situations. Regular mattresses are built for stationary use and may not handle the bumps and movement that come with RV travel. Additionally, RV beds are often smaller and more uniquely shaped than regular beds, so a regular mattress may not fit properly.
Using a regular mattress in your RV can also put unnecessary strain on your RV’s weight capacity, which could affect your fuel efficiency and performance. For the best results, it’s recommended to choose a mattress that’s specifically designed for RV use.
Conclusion
Choosing the right camper trailer mattress size is key to enjoying a comfortable sleep while on the road. With so many options available, knowing the different types of RV mattresses and their sizes can help you find the perfect fit. Whether you're looking for a memory foam mattress or a traditional innerspring, make sure to measure your space and consider your personal comfort needs.
