Landscape mode may refer to any of the following:
1. With graphics or printing, landscape mode is a horizontal orientation of a document or image. Landscape mode is commonly used to print charts, wider images, and text that may not fit properly if the page is oriented in portrait mode (vertically).
Pictured is an example of printer options where the user can choose how the printing should be oriented. The top selection is portrait (vertical) orientation, which is taller than wide. The bottom selection is landscape (horizontal) orientation, which is wider than tall.
Most software offers a "page setup" option in the file menu, document settings, or preferences, where orientation can be chosen.
3. With computer monitors, landscape mode refers to most new models that are longer horizontally than vertically. The image below shows a landscape-oriented monitor. While the picture on the monitor defaults to landscape mode, it can be flipped to portrait mode in the monitor settings, if desired.
