RV mattress sizes are not the same as the sizes you buy for a house. The main RV-specific sizes are the RV short queen (60 x 75 inches), the RV queen (60 x 80 inches), the RV short king (72 x 75 inches) and the RV king (72 x 80 inches), according to the size chart from the Sleep Foundation. A short queen is about 5 inches shorter than a standard home queen, so a household queen can be too long for a short queen bed platform.
Because dimensions vary between RV models and mattress brands, always measure your own bed before ordering. Below is a full chart, then a step-by-step way to measure.
RV Mattress Sizes Chart
All dimensions are width x length in inches. Where sources differ, the table shows the range.
| RV mattress size | Dimensions (inches) | Notes |
|---|---|---|
| RV bunk | 28–35 x 75–80 | Bunk beds in family RVs; size varies by RV design |
| RV twin | 35–38 x 75 | Most often in entry-level travel trailers and bunkhouse models |
| RV three-quarter | 48 x 75 or 48 x 80 | One adult or two smaller children |
| RV full (double) | 53–55 x 75 | Smallest size that fits a couple somewhat comfortably |
| RV short queen | 60 x 74 or 60 x 75 | More common in RVs than a standard queen because it takes up less space |
| RV queen | 60 x 80 | Same as a home queen |
| RV short king | 72 x 75 | About 5 inches shorter than an RV king |
| RV king | 72 x 80 | 4 inches narrower than a home king |
| RV California king | 72 x 84 | Longer and narrower than a home king |
| Eastern (standard home) king | 76 x 80 | Same as a standard home king |

The word “king” means different things in an RV. An RV king (72 x 80) is 4 inches narrower than a standard home king (76 x 80), and an RV short king is also 5 inches shorter. The Sleep Foundation recommends confirming the exact measurements with the manufacturer before buying.
RV Queen Mattress Size: Short Queen vs Queen
The queen is where most mix-ups happen. An RV short queen is 60 inches wide and 74 or 75 inches long; an RV queen is 60 x 80, the same as a home queen.
- If your RV bed is a short queen, a standard 80-inch queen will be about 5 inches too long. Camping World notes it may not sit flat on the platform.
- If your bed is a full 80-inch queen, a regular queen mattress matches the length and width. Still check its thickness and weight (see the measuring steps below).
Escapees advises measuring a queen bed carefully, or you could end up with the wrong length mattress.
RV King Mattress and Short King
The RV king (72 x 80) and RV short king (72 x 75) share the same 72-inch width; the short king is about 5 inches shorter. Standard king sheets fit an RV king in a pinch but billow at the sides, according to Camping World; RV-specific bedding is sold in short queen, RV king and short king sizes.
RV Bunk Mattress Sizes
Bunks vary the most. Escapees lists bunk mattresses at 28–35 inches wide and 75–80 inches long, and the Sleep Foundation lists five common bunk sizes: 28 x 75, 30 x 75, 30 x 80, 34 x 75 and 35 x 79 inches. Measure each bunk separately. Escapees notes that a three-quarter bed often sits below a smaller bunk, though not always.
How to Measure an RV Mattress
- Measure the platform as well as the old mattress. Camping World suggests measuring your existing mattress first and always confirming the dimensions of the bed platform. Measure from side to side (width) and head to foot (length); Escapees notes the mattress must fit the bed base.
- Look for cut or rounded corners. Some RV beds have a corner cut off to leave room for a bathroom door or a closet. Escapees advises measuring any odd angles or corners; you may need a custom mattress.
- Check the height clearance. Escapees says the height of the space is easy to forget, especially in a truck camper. Make sure you still have room to roll over — and to put sheets on.
- Allow for slide-outs and built-in furniture. If a mattress is longer than the bed base and the bed sits against a dresser or under a counter, Escapees warns it can strain the slide-out or the furniture when the slide comes in.
- Note the thickness limit. Camping World points out that a mattress that is too thick can make an emergency exit unusable. Its mattress examples range from 4 to 14 inches thick.
- Ask about weight. RV mattresses typically rest on a sheet of about ⅜-inch plywood, and a residential queen can weigh up to 150 pounds, according to Camping World. Check the maximum mattress weight with your RV manufacturer.
Write the measurements, the corner shape and the maximum thickness on your phone before you shop. If your bed has a cut corner or an unusual length, custom RV mattress makers can build one to size, as Escapees notes, though these can cost more.
Choosing an RV Mattress for Comfort and Easy Access
A few points make a real difference for couples and for anyone who wants an easier bed to live with:
- Room to walk around the bed. Camping World notes that a mattress that is too long can keep you from comfortably walking around the bedroom, and that many RVs use shorter beds to leave space on either side. If you are still choosing between RV classes, check the bed layout on each floor plan.
- Lighter mattresses are easier to lift if the bed hinges up for storage. A foam mattress is usually best for RVs because of size and weight limits, according to the Sleep Foundation.
- Height matters. A thicker mattress raises the sleeping surface; check that you can still sit on the edge comfortably and that the emergency exit stays clear.
- Bedding: buy sheets labeled for your RV bed size. Camping World notes RV bedding is widely sold in short queen, RV king and short king sizes.
Frequently Asked Questions
What size is an RV queen mattress?
An RV queen is usually 60 x 80 inches, the same as a home queen, while an RV short queen is 60 x 74 or 60 x 75 inches. Measure your bed platform’s length to know which one you have; Escapees warns that guessing can leave you with the wrong length mattress.
Can I put a regular queen mattress in my RV?
Yes, if your RV has a full 60 x 80 queen platform, but check the thickness and the weight limit first. If it is a short queen (60 x 75), a regular queen will be about 5 inches too long and may not sit flat, according to Camping World.
What is the most common RV mattress size?
Camping World says a short queen (60 x 75) is more common in RVs than a standard queen because it takes up less space. Sizes still vary by model, so measure your bed platform and confirm the measurements with the manufacturer, as the Sleep Foundation recommends.
How thick should an RV mattress be?
There is no universal thickness, according to the Sleep Foundation. Camping World’s mattress examples range from 4 to 14 inches. Choose a thickness that keeps the emergency exit usable and leaves enough height above the bed to roll over and change the sheets.
Do RV mattresses need special sheets?
Short queen, RV king and short king beds fit best with RV-size sheets, which Camping World says are widely available. Regular king sheets will work on an RV king in a pinch, but they billow at the sides.
