Occupancy-based hotel room types A single room is intended to sleep one person and most likely has one king or queen bed in the room. Double rooms, sometimes called double-double rooms, have two separate beds.

A hotel room with a single bed is typically called a "Single Room" if the bed is intended for one person (usually a twin or "single" sized bed), but it is more commonly marketed as a "King Room" or "Queen Room" in modern hotels. In the hospitality industry, rooms are often named after the size of the bed rather than the number of people, so a "Standard King" implies one large bed for up to two people. If you are specifically looking for a room with one bed but extra space, it might be called a "Studio" or a "Junior Suite." It is important to distinguish this from a "Twin Room," which specifically contains two separate beds. For solo travelers on a budget, some European and Japanese hotels still offer true "Single" rooms with a tiny bed and minimal square footage, but in North America, the "Single" designation has largely vanished in favor of "King" or "Queen" rooms that can accommodate couples or solo travelers alike.
