What Is Aspect Ratio On a Monitor?

Aspect Ratio is used to measure the proportional height and width of a monitor. For example, a 16:9 monitor will have 16 pixels on the horizontal axis for every 9 pixels on the vertical axis.

How to Measure Aspect Ratio?

To measure the aspect ratio of a monitor, you need to measure the width and height of the screen in pixels or inches, and then divide the width by the height.
Here's how to measure aspect ratio on a monitor:

  1. Identify the resolution of the monitor. You can usually find this information in the product specifications or settings of your computer.
  2. Measure the width and height of the screen in pixels or inches. If you measure in pixels, make sure the monitor is set to its native resolution.
  3. Divide the width by the height to get the aspect ratio. For example, a resolution of 1920 x 1080 pixels would result in an aspect ratio of 16:9 (1920 divided by 1080 equals 1.78).

You can also use online aspect ratio calculators or tools to measure the aspect ratio of your monitor.

What Are Common Aspect Ratios?

Common aspect ratios for monitors include:

  1. 1.33:1 (4:3) - This aspect ratio was standard for many CRT monitors and early LCD monitors. It has since been largely replaced by widescreen aspect ratios.
  2. 1.66:1 (5:3) - This aspect ratio is commonly used in European cinema.
  3. 1.78:1 (16:9) - This is the most common aspect ratio for widescreen monitors and is used for HDTV and most video content.
  4. 1.85:1 - This aspect ratio is commonly used in North American cinema.
  5. 2.35:1 - This is an ultra-widescreen aspect ratio commonly used in cinema for panoramic shots. Some monitors with this aspect ratio are available for gaming and professional applications.
