How To Find The Aspect Ratio of An Image

Before we go into the different image sizes, it would be helpful to learn how to calculate the aspect ratio. That way, we can find out if we can use it “as is” on Facebook. 

To calculate it, we re-write the width and height of the image as a fraction and reduce it to its least common denominator. 

Let’s say we had an image whose dimensions are 1600 px by 900 px. If we wrote that as a fraction and simplified it, it would be 16/9, or a 16:9 aspect ratio.

4:5 aspect ratio can be used for images but Facebook highly recommends using them for video. 

As a caveat, the 4:5 ratio can only be used if the image doesn’t contain a link. Otherwise, you’re better off using either 1.91:1 or 1:1 aspect ratio.

Other than that, 4:5 can fit most other placements like Stories, Instant Article, and the Audience Network.
