What is the aspect ratio?
The dimensions of an image i.e. the ratio of the width and height is called the aspect ratio. Different camera devices and social networks use a wide range of aspect ratios that are known to the creators. The creators thus can resize or preset the aspect ratio of the image to make it suitable for posting. Here are a few common aspect ratios across display devices and posting platforms.
