RV mattresses almost never match a home mattress chart. Bunk beds, three-quarter beds, RV Queen and RV King are all cut narrower or shorter than their home-size names suggest, which is exactly why a regular fitted sheet ends up bunched, twisted, or popping off a truck sleeper or camper bed by the second night. Here's how an RV fitted sheet is actually sized, what sizes exist, and how to pick the right one for your rig.
Why a home fitted sheet doesn't work in an RV
A Queen mattress in your house measures 60x80 inches. An "RV Queen" often measures closer to 60x75 or even 60x74, a few inches shorter to fit around wheel wells, cabinets, and the tighter footprint of a camper or trailer. Bunk beds and truck sleeper beds are narrower still, some as tight as 28 inches wide. A home fitted sheet built for standard dimensions will either hang loose and bunch up under you, or the elastic will fight to stretch over a mattress it was never cut for, and either way it comes loose fast on a bed that's already moving down the highway.
RV mattress sizes
| Size | Typical use |
|---|---|
| Bunk 28x75 | Narrow truck sleeper or camper bunk |
| Bunk 34x75 | Slightly wider bunk or camper bed |
| Bunk 30x80 | Longer bunk configuration |
| Bunk 42x80 | Wider bunk bed setups |
| Three Quarter | Between Twin and Full width |
| RV Short Queen | Most common RV master bed size |
| RV Short King | Wider RVs and fifth wheels |
| RV King | Larger motorhomes and Class A RVs |
Even within these categories, manufacturers vary a few inches from rig to rig, so measuring your actual mattress before ordering is worth the extra minute, especially since RV beds are often tucked into slide-outs or built-in frames where a couple inches makes the difference between fitting and not.
How to measure your RV mattress before you order
Pull the mattress away from the wall or slide-out if you can, and measure width and length edge to edge with the bare mattress, not over an existing sheet or pad. Round to the nearest inch on each dimension. Then measure depth: straight down from the top surface to where the mattress meets the platform, adding the height of any topper. If your numbers land close to one of the standard RV sizes but not exact, order the closest size and lean on the 100% Fit Guarantee if it doesn't work out, rather than guessing at a custom cut you don't actually need.
Deep pockets and 360 elastic still matter on the road
If anything, a fitted sheet needs to hold on more securely in an RV than at home. A moving vehicle adds vibration and constant small shifts that work a loose sheet free far faster than a stationary bed ever would. SGI's RV fitted sheet comes with the same deep pocket and 360-degree all-around elastic used across its home lines, in 12" or 15" pocket depth depending on your mattress thickness, so the sheet grips the entire perimeter of the mattress rather than just the corners.

The RV fitted sheet is woven from long-staple 600 thread count cotton, breathable and smooth without needing special care, which matters when laundry access is limited on the road. It comes in 9 colors, White, Butter, Light Grey, Dark Grey, Taupe, Burgundy, Navy Blue, Black, and Moss, so a small space doesn't mean settling for whatever's left over.
Breathability matters more in an RV than it might at home too. Campers and trucks often run without the climate control of a full-size house, especially overnight with the engine off, so a fabric that traps heat is a real problem in summer. Long-staple cotton stays cooler and wicks moisture better than the polyester-blend sheets that tend to ship as generic RV bedding, which is part of why upgrading the stock sheets is one of the more noticeable comfort changes you can make in a small space.
If your bed doesn't match any of these sizes
Some rigs use a genuinely custom mattress shape that doesn't fit even the RV size chart. If that's your situation, SGI also makes a custom fitted sheet, cut to your exact measurements rather than any preset size, backed by the same 100% Fit Guarantee.
Care instructions
Machine wash in cool or warm water and tumble dry on low. The cotton is fade-resistant and holds its softness wash after wash, which matters for something that's going to live through a lot more loading, unloading, and road vibration than a sheet at home ever does.
A few common questions
Can I use a regular Queen sheet on my RV Queen mattress?
Usually not well. Most RV Queen mattresses run a few inches shorter than a home Queen, so a standard sheet will bunch at one end or fight the elastic trying to stretch over the wrong footprint. Measuring your actual mattress before ordering is the safest bet.
Why does the sheet come in 12" and 15" pocket depths?
RV mattresses vary in thickness more than people expect, from thin factory-original pads to thicker aftermarket upgrades. Picking the pocket depth that matches your actual mattress, plus any topper, keeps the sheet from riding up at the corners.
Does the RV fitted sheet come with pillowcases?
Yes, it ships as a 3-piece set: the fitted sheet plus 2 pillowcases with envelope closures.
What if my RV mattress is a non-standard shape?
SGI's custom fitted sheet can be cut to your exact measurements if none of the standard RV sizes match your bed.
