Height of the screen (in relation to aspect ratio)
The aspect ratio of an image describes the proportional relationship between its width and its height. The most common aspect ratios used today in the presentation of films in cinemas are 1.85:1 and 2.39:1. In still camera photography, the most common aspect ratios are 4:3, 3:2, and more recently being found in consumer cameras 16:9. Other aspect ratios, such as 5:3, 5:4, and 1:1 (square format), are used in photography as well, particularly in medium format and large format.
Often, screen specifications are given by their diagonal length. The height of the screen is related to the aspect ratio and the diagonal length
