Aspect Ratios Explained.
An aspect ratio represents the proportional relationship between a display or media file's width and its height. It is written as two numbers separated by a colon, such as 16:9.
For example, a widescreen aspect ratio of 16:9 means that for every 16 units of width, there are 9 units of height, regardless of the physical size or absolute pixel measurements.
