Monitor Aspect Ratio (Definition, Importance and Examples) 🖥️ 2021

First let's define aspect ratio.

Definition

The aspect ratio is a ratio between width and height. It is represented as two numbers separated by a colon (4:3, 16:9, and 21:9).

Let's say you have high definition video (Full-HD) and want to know what is his aspect ratio.

Full HD resolution is 1920 pixels wide and 1080 pixels high. So the screen aspect ratio calculation would be as follows:

1920/1080 = 16/9 or 16:9.

16:9 literally means "16 divided by 9".

Typical monitor aspect ratios

Typical monitor aspect ratios are:

  • 4:3.
  • 16:9.
  • 21:9.

Examples:

  • (1): Cameras.
  • (2): Computer monitors. 
  • (3): Computer monitors. 
  • (4): Widescreen computer monitors.
  • (5): TVs and widescreen computer monitors.
  • (6): Cinema.
  • (7): CinemaScope (A kind of movie).

You can find what your aspect ratio is in sites like:
