What is aspect ratio?
Aspect ratio refers to the relationship between the width and the height of an image or display. It is expressed as two numbers separated by a colon, such as 16:9 or 4:3.
The first number represents the width of the image or display, while the second number represents the height. For example, an aspect ratio of 16:9 means that the width of the image or display is 16 units, while the height is 9 units. This is the aspect ratio commonly used for widescreen displays, such as those found on TVs and computer monitors.
An aspect ratio of 4:3, on the other hand, means that the width of the image or display is 4 units, while the height is 3 units. This is the aspect ratio commonly used for traditional TVs and computer monitors.
Aspect ratio can be important for a number of reasons. In photography, for example, the aspect ratio of the camera’s sensor or film can affect the composition of the photograph and the way it is framed. In video, the aspect ratio can affect the way the video is displayed on different devices, such as TVs or mobile phones. It can also affect the way the video is edited and the way it looks when it is played back.
