RV Mattress Sizes

Quick answer: the most common RV mattress size is the RV Queen Short: 60″ × 75″ — the width of a home Queen, 5 inches shorter. RV beds are rarely standard home sizes, so measure your platform before you buy anything. The chart below covers every common RV and camper size.

RV Mattress Sizes Chart

RV Size	Inches (W × L)	Centimeters	Notes
RV Queen Short	60″ × 75″	152 × 191 cm	Most common RV size
RV Short King	72″ × 75″	183 × 191 cm	Wider, same shorter length
RV Queen	60″ × 80″	152 × 203 cm	Same as home Queen — measure first
RV King	72″ × 80″	183 × 203 cm	Narrower than home King (76″)
RV Full / Double	54″ × 75″	137 × 191 cm	Small travel trailers
RV Twin	38″ × 75″	97 × 191 cm	Common in smaller RVs
RV Bunk (common)	28″ × 75″ / 30″ × 80″ / 35″ × 79″	varies	Always measure — bunk sizes vary by model
Three-Quarter	48″ × 75″	122 × 191 cm	Older campers and some vans

Our chart agrees with the Sleep Foundation’s RV mattress sizes chart, including its warning that dimensions vary between manufacturers and models.

How to Measure Your RV Bed

Because rv mattress sizes are set by each manufacturer rather than one national standard, the platform in your vehicle is the only measurement that counts.

1. Measure the platform, not the old mattress — width and length, wall to wall.
2. Check for rounded corners — many RV mattresses have radius corners at the foot; note the radius if you order custom.
3. Measure overhead clearance on bunks and cab-over beds before choosing a thickness; RV mattresses are typically 5″–8″ thick, thinner than home mattresses.

Travel trailers and fifth wheels usually follow the same chart: Short Queens in the main bedroom, narrow bunks (often 28″–35″ wide) for kids. Pop-up campers commonly use sizes close to 48″ × 72″ or 60″ × 80″ depending on the model — again, the platform measurement is the only reliable guide. Home sizes are listed in our mattress sizes chart for comparison, and home Queen dimensions are on their own page.

Short Queen and bunk sheets are the usual RV headache — our sheet sizes guide has a section on special and RV sizes.

If you are new to the vehicle types behind these bed layouts, the RV Industry Association’s guide to what an RV is explains the classes — motorhomes, travel trailers, fifth wheels and truck campers — that these sizes are built for.

If your trailer happens to fit a true home size, compare it against the standard Queen dimensions (60″ × 80″) before assuming you need an RV-specific model.

Oversized Mattresses: Texas, Wyoming, Alaskan King and Family Beds

At the opposite extreme from RV bunks sit the oversized home sizes, sold for very large primary bedrooms and families who share one bed. They are specialty products — expect custom or semi-custom pricing, long lead times, and bedding from the same maker rather than a store shelf.

Two practical warnings before you fall for the square footage. First, access: a one-piece Alaskan King will not turn through a standard doorway or stairwell, so these mattresses are usually shipped in sections or built with a fold. Second, support and bedding: frames are custom, sheets are made to order, and rotating a mattress this size is a two-person job. For almost every household, a standard King (76″ × 80″) plus a child’s own bed is the cheaper and easier answer — oversized sizes earn their cost only when the whole family genuinely sleeps together every night.

For the home version of the biggest bed in this chart, see our King size bed dimensions guide — note the home King is 4 inches wider than the RV King.

Replacing an RV Mattress: Three Checks First

When the factory mattress wears out — most are thin foam that lasts a few seasons — run these checks before ordering from the chart above. Weight: slide-out bedrooms have weight limits, and a thick residential-style mattress can strain the mechanism, so stay near the original’s weight class. Corner shape: note any radius (rounded) corners and order the same corner cut, or the replacement will overhang the platform. Door and hatch access: the new mattress has to enter through the RV door or a cargo hatch, so a flexible foam or roll-packed model is often the only realistic choice in a trailer with a narrow entry.

Using an RV bunk as a kids’ bed on the road works the same way as at home — the Twin size guide covers bunk thickness limits and guard-rail rules.

Frequently Asked Questions

What is the most common RV mattress size?
The RV Queen Short, 60″ × 75″ — Queen width in a shorter length to fit RV bedrooms.

Can I use a regular home mattress in an RV?
Only if the platform is a true home size (some RVs do fit a standard 60″ × 80″ Queen). Most RV platforms are shorter or narrower, and home mattresses are heavier and thicker, which matters for slide-outs and weight limits.

Are RV king mattresses the same as home kings?
No. An RV King is usually 72″ × 80″ — 4 inches narrower than a home King (76″ × 80″).

What thickness should an RV mattress be?
Typically 5″ to 8″. Check slide-out and bunk clearances before choosing; thicker is not always possible.
