What is Aspect Ratio?

The aspect ratio of an image or screen is the proportional relationship between its width and its height. It is commonly expressed as two numbers separated by a colon, such as 16:9. For every 16 units of width, there are 9 units of height. This ratio determines the shape of the rectangle, regardless of its actual size. Maintaining the aspect ratio is essential when resizing images or videos to prevent them from becoming stretched or distorted.
