Assuming you are talking about queen size beds in the United States, they are typically 60 inches wide by 80 inches long. This gives each person 30 inches of width, or about 2.5 feet. Most people can comfortably fit on a queen size bed, although some may find it a bit snug. Two people can sleep on a queen size bed comfortably with room to spare, or four people can sleep on it if they are willing to be cozy.
