A document with a horizontal dimension greater than its vertical dimension is in landscape orientation.

Explanation:

Screen orientation implies the way in which a screen is displayed, either vertically or horizontally, so that the device organizes the text and the digital display through its pivot function, which allows the screen to be rotated 90º without lose the content that is being displayed.

There are two screen orientations, the vertical or portrait, which focuses on the height and not the amplitude; and the horizontal or landscape, which expands the amplitude and cuts the height of the screen.
