Room size for a queen bed
The Sleep Foundation recommends about 24 inches of space around each side of the bed. With 24 inches on both sides and at the foot, a queen needs a clear floor area of at least 108 x 104 inches (9' by 8' 8"), before you add nightstands or a dresser. The mattress itself covers 33.3 square feet.
Rug size
Wayfair recommends a 8' x 10' rug under a queen bed, reaching at least 18 to 24 inches past the sides when all the bed legs sit on it. More rug placement rules.
