Camper Mattress Sizes | What Fits Your RV

Camper mattress sizes are not universal — they follow RV-specific dimensions like short queen (60 x 75 in) and RV king (72 x 80 in), which often differ from home beds.

Most people discover the hard way that a “queen” in an RV is not the same as a queen at home. Camper mattress sizes vary by floorplan and manufacturer, and assuming the name matches a household bed is the fastest route to a bad purchase. The good news: once you measure your platform, the right fit is straightforward.

The Common Camper Mattress Sizes You’ll Encounter

RV mattresses come in a handful of standard dimensions, though the exact size depends on your camper’s layout. The single most common is the short queen, which is 5 inches shorter than a standard home queen.

• RV short queen — 60 x 75 in
• RV queen — 60 x 80 in
• RV king — 72 x 80 in
• RV short king — 72 x 75 in
• RV full/double — 53 x 75 in
• RV three-quarter — about 48 x 75 in
• RV twin — about 38 x 75–80 in
• RV bunk — roughly 28–35 x 75–80 in

As Camping World’s RV mattress guide points out, these dimensions are consistent across most current RVs, but the truth is there is no official universal US standard for camper mattresses. The practical rule is to match the size your RV manufacturer specifies for that exact bed.

How RV Sizes Compare To Home Mattresses

If you’re replacing a mattress, the difference between household and RV dimensions matters. A standard home queen is 60 x 80 in, so an RV short queen is simply that queen cut 5 inches shorter. Similarly, a standard king is 76 x 80 in, while an RV king is typically 4 inches narrower at 72 x 80 in.

Full-size beds translate more directly. A standard full is 54 x 75 in, and the RV full or double at 53 x 75 in is close enough that many buyers find compatible options. The real surprises live in bunks and compact campers, where custom sizing is the norm. Bunk mattresses alone can measure anywhere from 28 x 75 in to 35 x 79 in depending on the model, and some RV twins appear as 38 x 75 in while others use 38 x 80 in.

Measuring Before You Buy Is Non-Negotiable

The most common mistake in camper mattress shopping is buying by name alone. A bed labeled “queen” in an RV is often the short queen, not the home size, and assuming otherwise leads to a mattress that hangs off the platform or jams against the walls.

Before ordering, measure the platform itself, not the old mattress. Check the actual length and width of the sleeping surface, note whether the corners are square or radiused, and verify the depth limit — a mattress that is too thick can interfere with bunk rails, cabinet doors, or slide-out mechanisms. A tape measure costs five minutes and saves a return shipping fee.

As Tom’s Guide’s RV mattress guide notes, published dimensions can vary between manufacturers and layouts, which is why the manufacturer spec for your specific model is the final authority. When in doubt, the floorplan diagram in your RV owner’s manual settles the argument.
