A history rundown of 16:9 aspect ratio in cinema

16:9 aspect ratio history

16:9 came to revolutionize the 4:3 standard ratio in 1984

A member of the SMPTE Working Group on High-Definition Electronic Production, Dr. Kerns H. Powers, proposed the 16:9 (1.77:1) aspect ratio in 1984.

This was back when nobody was creating 16:9, and the popular choice was 4:3, which was based on TV standard’s ratio at the time.

Dr. Kerns H. Power experimented further and figured out that those aspect ratio rectangles fit within an outer rectangle with an aspect ratio of 16:9 (1.77:1); all of them also covered a smaller standard inner rectangle with the same aspect ratio 16:9 (1.77:1).

The most common choice 4:3 and 2.40:1 video was recorded using a shoot and protect technique that kept the main action within a 16:9 inner rectangle to facilitate HD broadcast.

In the early 1990s the 16:9 aspect ratio gain popularity

After that, in the early 1990s, the European Union instituted the 16:9 Action Plan to accelerate the development of the advanced television services in 16:9 aspect ratio, both in PALplus and in HD-MAC (early HD format).

A decade later almost every computer industry switched to 16:9

Over almost 10 years, in the late 2000s and early 2010s, the computer industry switched from 4:3 to 16:9, the most common aspect ratio for monitors and laptops.

There were several reasons for this shift, including the ability for manufacturers to expand their product ranges by offering the products with wider screens and higher resolution.

This helped consumers quickly adopt such products, and by using the same aspect ratio for both TVs and monitors, manufacturing could be streamlined, and research costs could be reduced.

In March 2011, the 16:9 resolution 1920 x 1080 became the most commonly used resolution among Steam’s users.
