Short King Mattress Dimensions: 72x75 and 70x74
Short king mattress dimensions are often 72 x 75 inches, but some RV beds measure 70 x 74 inches. Measure the platform before ordering, since the name alone doesn't confirm the fit.

Short king mattress dimensions are often 72 x 75 inches, but some RV platforms measure about 70 x 74 inches. Measure your bed frame before ordering, because “short king” doesn't always mean one exact size.
Check the usable length and width, including any rounded corners or cutouts. A mattress that is even a little too large can press against walls or cabinets, while a smaller one can leave gaps.
What are the standard short king mattress dimensions?
A common RV short king measures 72 inches wide by 75 inches long. Some compact RV beds are closer to 70 x 74 inches, so the mattress name isn't enough to confirm a fit.
Measure the platform from edge to edge at the head, middle, and foot. If the measurements vary, use the tightest usable width and length when comparing mattresses.
The EGO White is a 10-inch memory foam mattress sized 72 x 75 inches. Its size makes it an option for a platform that measures close to those dimensions.
The Roam 2.0 is also 72 x 75 inches, with a 12-inch hybrid build and pocketed coils. Its extra thickness makes platform and overhead clearance worth checking.
For more options in this size, see our guide to RV short king mattresses for 72 x 75 beds.
How do you measure an RV short king bed?
Measure the inside length and width of the mattress platform, not the outside of the bed frame. Record the smallest usable measurements if the platform is tapered or has rounded corners.
Use a tape measure and keep it level across the surface. Check whether the head or foot has a notch, a curve, or another shape that a rectangular mattress might cover.
Also measure the available height beneath windows, cabinets, and other fixtures. A thicker mattress can change how much clearance remains around the bed.
Should you choose a 72 x 75 or a 70 x 74 mattress?
Choose a 72 x 75 mattress only if the platform has room for its full footprint. If your measurements are closer to 70 x 74, look for a mattress made to those dimensions or ask about a custom fit.
Don't assume foam will compress enough to solve a mismatch. A mattress can push against the frame, lose usable sleeping space, or sit unevenly if the fit is too tight.
If the bed shape or dimensions are unusual, our guide to custom RV mattresses made to order explains when a custom size may make sense.
Is an RV short king the same as an RV king?
An RV short king is usually shorter than an RV king, although the labels vary by brand and bed frame. An RV king is commonly around 72 x 80 inches, while a short king is often 72 x 75 inches.
Compare the actual length and width before choosing between the two. Our guide to RV king versus regular king dimensions explains how RV king measurements compare with a standard king.
A short king isn't the same as a short queen, either. For queen-size measurements, see RV queen mattress sizes, including 60 x 80 and 60 x 75.
What should you check besides mattress length and width?
Check the bed shape, mattress thickness, and surrounding clearance before you order. A close match in length and width may still be wrong if the platform has corners or fixtures that need extra room.
Measure the mattress thickness your bed can accept. The 10-inch EGO White and 12-inch Roam 2.0 have the same listed footprint but different profiles.
A topper also needs a size and pocket depth that suit the mattress. The ELEMUSE RV Short King Pillow Top Topper has a soft, overfilled construction and a deep pocket described as fitting 8 to 21 inches.
Its stated size is RV king at 72 x 80 inches, so compare that footprint with your short king mattress before choosing it. A topper that's too large may bunch or hang over the edges.
How do you choose a short king mattress that fits?
Start with your platform measurements, then match the mattress length, width, and shape. For a platform near 72 x 75 inches, the EGO White and Roam 2.0 share that footprint; compare their 10-inch foam and 12-inch hybrid builds against your clearance.
For a bed closer to 70 x 74 inches, don't rely on the short king label alone. Look for a closer size or consider a made-to-order mattress, and measure again before placing an order.
Frequently asked questions
What are short king mattress dimensions?
A common RV short king mattress measures 72 x 75 inches, though some beds are closer to 70 x 74 inches. Measure the platform's length and width at several points, then check for rounded corners, cutouts, and clearance before choosing a replacement.
Is a short king the same as an RV king?
The names can overlap, but they don't guarantee identical dimensions. RV king beds are often around 72 x 80 inches, while short king beds can be 72 x 75 inches or smaller.
Measure your bed frame and compare both dimensions before ordering.
Will a regular king mattress fit a short king bed?
A regular king mattress is much wider and longer than a short king, so it generally won't fit an RV short king platform. Check the frame's usable space and nearby walls or cabinets, then compare it with the mattress dimensions.
Can I use a topper on an RV short king?
A topper can add cushioning, but its dimensions should match the mattress and its pocket depth should fit the mattress thickness. Measure both before buying.
A loose or oversized topper can bunch at the edges or interfere with nearby RV fixtures.
