A full (double) mattress measures 54"x75". See the minimum room size, how much clearance you get, and what furniture fits alongside it.
Whether it fits comes down to the measurements most people skip.
Real openings run about 1 to 2 inches under the labeled size, and a single inch can flip the result. Check your own measurements before you buy or move.
Verdicts compare all six item orientations against the space using verified building standards. See our methodology

Frequently asked
A 9x10 foot room (108"x120") is the minimum. This gives you 27" of clearance on each side and 45" at the foot. For nightstands on both sides and a dresser, aim for 10x10 or larger.
01In rooms under 10x10, a full bed gives you 3" more clearance per side and 5" more at the foot compared to a queen. The difference is modest but can be the margin that makes nightstands workable.
02Yes, in a room at least 10x10. Place the bed against one wall and a 48" desk against the opposite wall. You will have about 45" between the bed foot and the desk — enough for a chair with room to push back.
