The single most important thing about buying an RV mattress is getting the size right — and RV sizes are not the same as the ones in your house. Order a standard queen for a spot that needs an RV Short Queen and it simply won’t fit. This guide explains every common RV mattress size, how each differs from its household equivalent, and exactly how to measure your rig so you buy the right one the first time.
Why RV mattress sizes are different
RV manufacturers shave inches off standard mattress dimensions to save space and weight inside the rig. That’s why an “RV Queen” is shorter than a household queen, and why bunks use a whole range of odd, narrow cutouts. The differences are usually just a few inches — but a few inches is the whole game when a mattress has to drop into a fixed frame. Always match the RV size exactly rather than assuming a household size is close enough.
RV Short Queen (60″ x 75″)
The most popular RV size and the most common upgrade. An RV Short Queen is 60 inches wide by 75 inches long — the same width as a household queen, but five inches shorter. It’s found in the majority of travel trailers and fifth wheels. If your rig has a “queen” bed, measure it: there’s a good chance it’s actually a Short Queen.

RV Queen & standard Queen (60″ x 80″)
Some newer or larger RVs fit a full-length queen (60″ x 80″), the same as a household queen. Others use an RV Queen that’s slightly shorter. Because “queen” can mean either in an RV, measuring is essential — don’t assume. Our best RV Short Queen guide covers the most common case.
RV King (72″ x 80″ or 76″ x 80″)
An RV King is typically 72 or 76 inches wide by 80 inches long — narrower than a household king (76″ x 80″) in many rigs, giving you residential-length sleep in an RV-friendly width. Larger motorhomes and luxury fifth wheels are where you’ll find these. Confirm whether yours is 72 or 76 inches wide before buying.

RV Bunk sizes (many dimensions)
Bunks are the trickiest — there’s no single standard. Common RV bunk dimensions include 28″ x 75″, 30″ x 75″, 30″ x 80″, 32″ x 74″, 34″ x 75″, 35″ x 79″, and 42″ x 80″. Because they vary so much, measuring your exact bunk cutout is non-negotiable. Bunk mattresses are also thinner — usually 5–6 inches — to fit the compartment and leave headroom. See our best RV bunk mattress guide.

RV Twin, Short Full & Short King
Rounding out the lineup: RV Twin (usually 38″ x 75″ or 38″ x 80″), Short Full (53″ x 75″), and Short King (72″ x 75″ or 72″ x 80″). These appear in smaller campers, vans, and specialty layouts. As always, measure before you buy — the “short” versions trim length to fit the rig.
How to measure your RV mattress
Do this before you order anything. Remove the old mattress and measure the flat bed platform or cutout, not the old mattress (which may have shrunk or been trimmed). Measure width, length, and available height (headroom above the platform, accounting for any slide-out or storage lid). Round to the nearest inch and match to the sizes above. If you’re between sizes, size down slightly — a mattress that’s a hair small will fit; one that’s too big won’t.
Frequently asked questions
Is an RV Short Queen the same as a regular queen? No — same width (60″) but 5 inches shorter (75″ vs 80″). It’s the most common RV bed size.
How do I know what size my RV mattress is? Measure the bed platform inside your rig (width x length x available height). Don’t assume “queen” means a household queen — many RVs use Short Queen.
Are RV king mattresses smaller than regular kings? Often yes — many RV kings are 72″ wide versus a household king’s 76″, though some are full 76″ width. Measure to confirm.
What size are RV bunk mattresses? They vary widely — 28″ to 42″ wide and 74″ to 80″ long. Measure your exact bunk cutout before buying.
The bottom line
RV mattress sizes trim inches off household dimensions to fit the rig, and getting the size right is the whole ballgame. RV Short Queen (60″ x 75″) is the most common by far, RV Kings run narrower than household kings, and bunks come in a dozen odd sizes. Measure your bed platform — width, length, and available height — before you order, size down if you’re between, and your new mattress will drop right in.
