How Aspect Ratios Have Changed Over Time Because of Movies

By Casey Chan on at

If you haven't learned anything interesting today, watch this fascinating history lesson on how the aspect ratios we know (16:9, 4:3) became the standard of what we see. For any film geek or ratio nerd, it's a lovely trip back into time where things can become standard by just doing it for a long time.

Probably the best wrinkle in aspect ratio history is how 16:9 came about: old 4:3 movie theaters birthed 4:3 television sets, which stopped people from going to 4:3 movie theaters, which made 4:3 movie theaters go widescreen to offer something different at home (which also eventually gave way to widescreen TVs).
