What is an Aspect Ratio?

An aspect ratio defines the relationship between the width and height of an image or screen. Common choices like 16:9 (widescreen) or 4:3 (standard television) dramatically impact how a story feels visually.

A Brief History of Notable Aspect Ratios:

4:3 (1.33:1): Once the dominant format for early cinema and television, seen in classics like The Wizard of Oz(1939).
16:9 (1.78:1): Standard for HDTV and streaming content today, perfect for YouTube, Netflix, and broadcast TV.
