What Are The Dimensions Of An RV King Mattress? Size Guide & FAQs
If you’re wondering “What Are The Dimensions Of An Rv King Mattress”, you’re likely trying to figure out whether a king mattress will fit in your RV or replace an existing RV king bed. RV mattress sizes can be confusing, because they often differ from standard residential sizes. This guide breaks it down clearly.
What is an RV king mattress?
An RV king mattress is a king-size mattress made specifically for recreational vehicles. It is designed to fit the compact, sometimes irregular bed platforms found in motorhomes, fifth wheels, and travel trailers.
Unlike a standard home king mattress, an RV king can be shorter, narrower, or both, depending on the model of the RV and its available floor space.
What Are The Dimensions Of An RV King Mattress?
The most commonly used RV king mattress dimensions are:
| RV King Type | Approx. Dimensions (W × L) |
|---|---|
| Standard RV King | 72" x 80" |
| Narrow RV King | 70" x 80" |
| Short RV King | 72" x 75" |
These are typical industry dimensions, but there is no single universal RV king size. RV manufacturers may use slightly different measurements, so it’s important to measure your existing mattress or bed platform before ordering.
How is an RV king different from a regular king?
A standard residential king is usually about 76" x 80". Comparing that to common RV king sizes:
- A standard RV king (72" x 80") is typically 4 inches narrower than a home king.
- A narrow RV king (70" x 80") is about 6 inches narrower.
- A short RV king (72" x 75") keeps the width of a standard RV king but is about 5 inches shorter.
This difference matters because:
- A regular king mattress might overhang the platform in an RV.
- Overhang can interfere with doors, slide-outs, storage compartments, or walking space.
- Sheets and bedding for a regular king may not fit well on an RV king, and vice versa.
Why do RV king dimensions vary?
RV interiors are designed to maximize space, often with:
- Slide-outs that need clearance when moving
- Curved or angled corners
- Built-in storage under or around the bed
To accommodate these layouts, manufacturers often specify custom mattress dimensions, leading to several common RV king formats rather than one fixed size.
How do I know which RV king size I have?
To figure out what RV king dimensions you need, measure your current mattress or the bed platform:
- Measure the width
- From one side edge to the other, at the widest point.
- Measure the length
- From the head to the foot of the bed, along the center.
- Check for special features
- Rounded corners, cut-outs, or notched areas
- Hinges or folding sections on the base
- Surrounding cabinets or walls that restrict space
Then compare your measurements to common RV king sizes like 72" x 80", 70" x 80", or 72" x 75". When in doubt, use the platform size rather than relying only on an older or compressed mattress.
Can I use standard king bedding on an RV king mattress?
It depends on which RV king you have:
- On a 72" x 80" RV king, standard king sheets may fit loosely because the mattress is narrower.
- On a short RV king (e.g., 72" x 75"), standard king sheets might bunch at the foot since they’re made for an 80" length.
- Fitted sheets are usually the most affected; flat sheets and blankets can be more forgiving.
Many RV owners:
- Use RV-specific king sheets when possible, or
- Opt for deep-pocket king sheets and tuck them more tightly, especially with narrower or shorter mattresses.
What should I consider before replacing an RV king mattress?
When looking at What Are The Dimensions Of An Rv King Mattress in the context of replacement, it helps to think beyond just width and length:
- Thickness / Height
- A very thick mattress can reduce headroom or make it harder to sit up if there are overhead cabinets.
- Access and weight
- Heavier mattresses can be harder to move through tight RV doors or lift if there’s storage under the bed.
- Bed frame design
- Some RV beds lift on gas struts or fold; the mattress size and weight should work with that mechanism.
- Sleeping partners
- A wider RV king, when possible, can provide more personal space for two sleepers.
