Overview & History
The term "aspect-ratio" refers to the proportional relationship between the width and height of a display or image. It is commonly expressed as two numbers separated by a colon, such as 16:9. Aspect ratios have been a fundamental concept in various fields, including photography, film, and web design, for decades. Historically, different industries have adopted different standard aspect ratios based on technological and aesthetic considerations.
