If a door opens not "into" a room but rather "out of" the room, it is called "outward-opening". Typically, doors and fittings are installed so that the door swings into the room you want to enter. It essentially moves away from a designated "traffic area," such as a hallway. Exceptions may occur in very small rooms because the option to open outward has a significant advantage: it saves a lot of space. However, be sure to adhere to the standard regulations. In rooms with an area below 1.80 m², only doors that open outward may be installed.
