Will a sleeping bag fit on an RV bunk?

Answered by RV Parts Giant · Upland, CA · November 9, 2026

Short answer: Usually, if you match length as well as width. Most RV bunks are about 75 in long and 30 to 38 in wide. A 75 x 33 in bag like the REDCAMP fits that length exactly. The common 86.6 in long bags hang about 12 in past a 75 in bunk. For an RV short queen (60 x 75 in), a 2-person bag about 59 in wide matches the width.

Plenty of families put sleeping bags on the bunks instead of making them up with sheets. The bag rolls up in the morning, and the kids sleep in their own. Whether it fits comes down to two numbers, and on most bunks it is the length, not the width, that catches people out.

Know your bunk

Most bunk mattresses we sell are about 75 in long. Widths come in three sizes: a narrow bunk of about 30 to 31 in, a twin at about 38 in, and an RV three-quarter at 48 in. See do twin sheets fit an RV bunk for how to tell which you have. RV short queens are 60 x 75 in.

Bag sizes against a 75 in bunk

Bag	Size	On a 75 in bunk
REDCAMP cotton flannel	75 x 33 in	Same length as the bunk; 33 in wide covers a narrow bunk with 2 to 3 in to tuck
TANSTRIDER 4-season	86.6 x 31.5 in	About 11.6 in longer than the bunk; 31.5 in fits a narrow bunk's width
Kanyak waterproof, rated 32°F	86.6 x 32.48 in	Also about 11.6 in over; good for adults and tall teens
FUNDANGO 2-person queen, 39–63°F	220 x 150 cm (about 86.6 x 59 in)	Matches a 60 in short queen's width, with the same length overhang

The overhang is our own subtraction: an 86.6 in bag on a 75 in bunk leaves about 11.6 in to fold under at the foot or let hang over the end. On an upper bunk with a rail or end wall, fold the foot under. On a dinette bed, it drapes over the edge.

Pick the length by who sleeps there

Kids and short sleepers on a 75 in bunk: a 75 in bag lies flat with nothing to fold.
Adults or tall teens: the 86.6 in bags give foot room, and the extra length simply folds under.
Couples on the short queen: the FUNDANGO zips two people into one bag about 59 in wide.

Warmth

Each listing gives a temperature rating: 32°F for the Kanyak, 39–63°F for the FUNDANGO queen. Match it to the coldest night inside the rig, which depends on whether the furnace runs overnight. Keep fitted bunk sheets for the nights you want a made-up bed. The 31 x 75 in pair fits narrow bunks where twin sheets hang loose.
