How wide is a queen bed frame?

A queen bed frame is 60 inches wide, matching the standard queen mattress dimension of 60″ × 80″ (width × length).

Most queen bed frames are built to fit a 60-inch-wide mattress snugly, though the outer frame footprint typically runs 63–65 inches wide once rails and any side flanges are included. Platform frames with built-in slats stay closer to 62 inches outer width, while metal frames with bolt-on side rails often reach 64–65 inches. Always measure the outer frame dimensions before placing a queen bed frame in a room, not just the mattress size.
