What Size Mattress Is in a Pop Up Camper? Mattress Dimensions Explained

If you’re wondering “What Size Mattress Is In a Pop Up Camper”, you’re usually trying to figure out whether you can replace, upgrade, or add a topper to your current camper beds. Pop up campers don’t always use standard mattress sizes, so getting this right can save you time, money, and frustration.

Below is a clear breakdown of typical pop up camper mattress sizes, how they compare to standard beds, and what to check before ordering anything new.

Are Pop Up Camper Mattresses Standard Sizes?

In many cases, pop up camper mattresses are close to standard bed sizes (like full, queen, or king), but they are often shorter, narrower, or rounded at the corners to fit the camper’s layout.

Common patterns you’ll see:

• One or two slide-out bunk ends (beds that extend from the sides/front/back)
• A dinette area that converts into a smaller sleeping surface
• Non-standard lengths, such as 72–75 inches instead of 80 inches

Because of this, the answer to “What Size Mattress Is In a Pop Up Camper” is usually: “It depends on your specific model, but it will be close to a standard bed size with custom dimensions.”

Typical Mattress Sizes Found in Pop Up Campers

While there’s no universal standard, many pop up campers use mattress sizes in this range:

These are typical ranges, not guarantees. Many campers use a version of “RV short queen” (60 x 75) or slightly modified king or queen sizes.

How Can I Find the Exact Mattress Size in My Pop Up Camper?

The most reliable way to answer “What Size Mattress Is In a Pop Up Camper” for your specific rig is to measure it directly.

Steps to measure your camper mattress

1. Remove bedding and toppers
   Strip away sheets, pads, and covers so you can see the original sleeping surface.

2. Measure the platform, not just the foam
   Use a tape measure to check:

   • Width: side to side
   • Length: head to foot
   • Thickness clearance: from the platform to the ceiling when closed, if possible

3. Note any shape quirks

   • Rounded corners
   • Angled sides
   • Cut-outs around cabinets or supports

4. Write measurements in inches
   Most mattress and foam sizes are listed in inches, so this helps you match more accurately.

📝 Tip: When in doubt, a mattress that is slightly smaller than the platform is usually easier to work with than one that’s too large and bunches up when closing the camper.

How Do Pop Up Camper Mattresses Compare to Home Mattress Sizes?

Pop up camper beds often mimic the width of home mattresses but change the length:

• A 60-inch-wide camper mattress is similar to a queen, but may be shorter (75 inches instead of 80).
• A 70–72-inch camper mattress is similar to a king, just sized for RV use.
• Smaller bunk ends and dinette beds are often narrower and shorter than a standard twin.

Because of these differences, standard fitted sheets may not fit well. Many campers use:

• Flat sheets tucked tightly
• Sheet straps or clips
• Slightly oversized sheets folded under

Can I Replace My Pop Up Camper Mattress With a Regular One?

Sometimes yes, sometimes no. It depends on:

1. Thickness and closing clearance

Pop up campers are designed to fold down with the mattress in place. If you add a thicker mattress:

• Make sure the roof still fully latches
• Check that nothing presses too hard on windows, canvas, or cabinets

2. Weight

Heavier mattresses can make lifting and lowering the roof more difficult. Lighter foam options are often easier for frequent setup and teardown.

3. Fit around corners and edges

If your existing mattress has rounded or cut corners, a standard rectangle mattress might:

• Overhang the platform
• Bunch up against walls or zippers
• Interfere with door closing

Many owners either:

• Use custom-cut foam to match their measurements, or
• Choose a standard size that’s close but slightly smaller, then fill any small gaps with pads or pillows.

What Should I Consider Before Upgrading My Pop Up Camper Mattress?

When thinking about What Size Mattress Is In a Pop Up Camper and how to improve it, consider:

• Exact platform measurements (width, length, clearance)
• Number of sleepers and their height
• Ease of setup (folding, roof lifting, storage)
• Weight and bulk when the camper is closed
• Comfort preferences (some prefer adding a topper rather than replacing the entire mattress)

Many people find that adding a thin topper sized to the existing mattress is a simple way to improve comfort without changing the mattress dimensions or creating fit issues.
