What is a 4:3 Ratio?

A 4:3 ratio is a proportional relationship between two numbers, indicating that the first number is four times larger than a single unit of the second number. This ratio is often used to describe the aspect ratio of images, screens, and photographs. For example, in a 4:3 aspect ratio, the width of an image is 4 units while the height is 3 units. This ratio was standard for television screens and computer monitors before the wide adoption of widescreen displays.
