They are wall-mountable, ceiling-mountable, and freestanding in a way that helps guide people safely and efficiently to where they need to go. In spaces such as universities, corporate buildings, and hospitals, arrow signs are a basic yet efficient way of wayfinding in spaces where there are multiple routes and multiple exits and entrances. In guiding people to lobbies, bathrooms, and exits, arrow signs are a basic and efficient way of directing movement.
