What Size Are Camper Mattresses? Guide to Common RV and Camper Bed Dimensions

If you’re wondering “What Size Are Camper Mattresses” before replacing or upgrading your RV bed, you’re not alone. Camper and RV mattresses can be confusing because they often don’t match standard home mattress sizes. This guide explains the most common camper mattress dimensions, how they compare to regular sizes, and what to check before you buy.

What Does “Camper Mattress Size” Actually Mean?

A camper mattress is a mattress designed to fit the limited and often irregular spaces in campers, RVs, travel trailers, and motorhomes. Even when a bed is labeled “queen” or “king” inside an RV, its dimensions may differ from a standard queen or king used at home.

So when you ask “What Size Are Camper Mattresses”, the real answer is: it depends on your RV model and bed type, but there are some common patterns.

Common Camper Mattress Sizes and Dimensions

Below is a simple table with typical camper mattress sizes. Actual measurements can vary slightly by manufacturer, but these are common reference dimensions:

These sizes are often called “RV” or “camper” to distinguish them from standard home sizes.

How Are Camper Mattress Sizes Different from Regular Mattresses?

Are RV queens the same as normal queens?

Not always. Many people discover that their “queen” RV bed is a “short queen”:

• Standard queen (home): 60" × 80"
• RV short queen: usually 60" × 74"–75"

This means RV short queens are about 5–6 inches shorter, which helps them fit better in tight spaces or around corners, but can feel short for taller sleepers.

What about king and twin sizes?

• RV king: Often 70"–72" wide × 80" long, which may be narrower than some home king options.
• RV twin and bunk sizes: These can be narrower and/or shorter than standard twin mattresses to fit bunk areas, over-cab spaces, or slide-outs.

Because of this, standard fitted sheets and mattress protectors may not fit camper mattresses correctly, especially in bunk or “short” sizes.

How Do I Find Out What Size My Camper Mattress Is?

If you’re trying to answer “What Size Are Camper Mattresses” for your specific RV, the easiest method is to measure the bed platform or current mattress.

Steps to measure your camper mattress

1. Remove all bedding so you can see the full mattress or platform.
2. Use a tape measure and record:
   • Width: from side to side
   • Length: from head to foot
3. Check if corners are rounded or if one side is cut or angled (common in some RVs).
4. Note any obstructions, like:
   • Walls on three sides
   • Cabinets, doors, or steps nearby
   • Slide-out mechanisms

These details matter because many camper beds are designed to clear overhead cabinets or allow a door to close, so extra length or thickness may cause issues.

Why Camper Mattress Size Matters

Knowing what size camper mattresses usually are helps you avoid:

• Ordering the wrong size, which may not fit the platform
• Mattress overhang, which can cause discomfort or uneven support
• Difficulty moving around in tight spaces (narrow aisles, end-of-bed clearance)
• Problems with slide-outs, where a mattress that’s too thick or long can get pinched

For many RV owners, the right mattress size is a balance between comfort and space efficiency.

Can I Use a Regular Mattress in My Camper?

Sometimes you can, but there are a few things to consider:

• Fit on the platform: A standard size may hang over the edge or block a cabinet or door.
• Weight: Some home mattresses are heavier, and RVs have weight limits and storage constraints.
• Flexibility: Getting a full-size mattress through narrow RV doors or around tight corners can be challenging.

Many people look specifically for RV or camper-sized mattresses because they’re designed to fit the unique dimensions and weight needs of mobile spaces.

✔️ Quick Mattress Takeaways

Key points consumers should understand about “What Size Are Camper Mattresses”
