About Aspect Ratio. The aspect ratio of an image defines the proportion between its width and height. It is always expressed as two numbers separated by a colon (x:y). For example, images with the aspect ratio of 16:9, no matter how big or small, will always have the width of 16 and the height of 9 units of the same length. Therefore, 16 centimeters wide and 9 centimeters high image as well as 32 centimeters wide and 18 centimeters high image has the same 16:9 aspect ratio. Time ago I did a research trying to find a solution to calculate aspect ratio of a resolution, and this answer helped me to write the code below, which works fine for all common resolutions, but I just discovered that it fails to calculate the aspect ratio for many other resolutions, for example my code below will give a result value of '683:384' when trying to calculate the aspect ratio for.

### 3 2 Aspect Ratio

Now, let’s say we want to calculate aspect ratio for an image that has 300px width and 150px height.
Aspect Ratio = Width / Height
Aspect Ratio = 300 / 150 = 2 / 1 => Aspect ratio of our image is 2:1
