1. What is the Aspect Ratio for Images?

The ratio of an image's width to its height is what we refer to as the aspect ratio, and it is represented by two numbers separated by a colon, such as 16:9. The image has an aspect ratio of x:y and is x units wide and y units height. In cinematography, common aspect ratios are 1.85:1 and 2.39:1; in television photography, 4:3 and 16:9. And in still photography, 3:2. The most common cinema aspect ratios are 1.85:1 and 2.39:1. The most common photography aspect ratios are 4:3, the universal video format of the twentieth century, and 16:9, then the universal for HD television and European digital television. Other cinema and film aspect ratios exist but are rarely used.

The most common aspect ratios in still camera photography are 4:3, 3:2, and, more recently, 16:9. Other aspect ratios, like 5:3, 5:4, and 1:1 or square format, are also used in photography, particularly in medium and large formats.
