A ballroom or ballhall is a large room inside a building, the primary purpose of which is holding large formal parties called balls. Traditionally, most balls were held in private residences; many mansions and palaces, especially historic mansions and palaces, contain one or more ballrooms. In other large houses, a large room such as the main drawing room, long gallery, or hall may double as a ballroom, but a good ballroom should have the right type of flooring, such as hardwood flooring or stone flooring .. For most styles of modern dance, a wooden sprung floor offers the best surface.

In a building or ship, a room is any enclosed space within a number of walls to which entry is possible only via a door or other dividing structure. The entrance connects it to either a passageway, another room, or the outdoors. The space is typically large enough for several people to move about. The size, fixtures, furnishings, and sometimes placement of the room within the building or ship support the activity to be conducted in it.
