What is Aspect Ratio?

Aspect ratio is the proportional relationship between the width and height of an image, video, or screen. It is typically expressed as two numbers separated by a colon (e.g., 16:9). The aspect ratio determines how content will appear on different displays and is crucial for photography, videography, web design, and UI development.
