RV mattress sizes
RV bed spaces are not the sizes you know from home. This is the list of names you will meet while shopping, with the dimensions usually attached to each one.
Sizes you will see in an RV
| Name | Inches | Centimeters | Where it turns up |
|---|---|---|---|
| Bunk | 28–34 × 75 | 71–86 × 191 | Bunk rooms. Widths vary more than any other size. |
| Twin | 38 × 75 | 97 × 191 | Single beds and some bunk rooms. |
| Three-quarter | 48 × 75 | 122 × 191 | Older and smaller trailers. |
| Full | 53 × 75 | 135 × 191 | Compact bedrooms. |
| Short queen | 60 × 75 | 152 × 191 | The most common RV bedroom size. |
| Queen | 60 × 80 | 152 × 203 | Same as home. Five inches longer than a short queen. |
| Olympic queen | 66 × 80 | 168 × 203 | Wider than a queen, not as wide as a king. |
| Short king | 72 × 75 | 183 × 191 | Larger coaches with a shortened platform. |
| RV king | 72 × 80 | 183 × 203 | Also sold as a narrow king. Four inches narrower than a home king. |
| King | 76 × 80 | 193 × 203 | The home size, listed here for comparison. |
The three catches
Short does not mean small
A short queen is the same width as a home queen and five inches shorter. That difference is the single most common reason a replacement mattress does not fit, because the name sounds close enough to risk it.
An RV king is not a king
An RV king, sometimes sold as a narrow king, is 72 inches wide. A home king is 76. Sheets cut for the home size will swim, and a home mattress will overhang the platform by two inches on each side.
Corners and bases change the answer
Plenty of RV platforms have a corner cut or rounded off so you can walk past the foot of the bed, and many lift up for storage underneath. Both affect what will actually drop into the space, whatever the label says.
Work out your own size
Measure the platform, then compare it against this list. The fit tool draws your space to scale, names the closest size for reference, and gives you a summary to send us. It does not confirm a fit: only your measurements can do that.
