In buildings, spaces whose main function is circulation are called corridor (or also corridor), and serve to connect different rooms or rooms, or even different elements in the same room. By their nature, hallways usually have a markedly longer dimension, corresponding to the direction of circulation, and a shorter one. When the proportion between length and width is not so pronounced, the corridor is called "hall", and can accommodate other specific uses, usually as a waiting area...

Corridors are common in homes, where they give access from the hall or living room to the interior rooms. With similar purposes there are also corridors in other buildings such as offices, hotels, educational centers, health centers, etc.

Aisles are found in stores, warehouses and factories, where they have shelves on both sides. In warehouses and factories aisles may consist of storage pallets and in factories aisles may separate work areas. In gyms, exercise equipment is usually arranged in hallways.

In today's homes, hallways usually have a width of 80 cm to 100 cm and their length depends on both the size of the house and the distribution of its rooms. The hallway is usually an interior area so it is important that it has good lighting. Due to its small dimensions, it does not accommodate much furniture, although it can accommodate small tables or chairs, sideboards or shelves, as well as various ornaments such as paintings, etc.

The term corridor is also applied to narrow transportation corridors and other centers and establishments.

Making the hallway is a gesture by which the players of a football, basketball or other sport team stand in two rows at the access door to the field so that those of the opposing team pass through the middle while applauding them. It is considered an act of tribute that is professed to the team that has just won the "League (sport)") or other sports competition. It is typical in the Spanish league.[2]​.
