Aspect ratio calculations matter a lot depending on whether it is an image, design project or a digital video you are working with.

Aspect ratios are largely defined by numbers, as in a mathematical ratio that clearly defines how many inches high and how many inches wide your video, image and design projects should be. While aspect ratios are measurements of the height and width, they are often reduced to the smallest usable ratio in order to fit perfectly in every medium.

To achieve a perfect aspect ratio, you must employ the use of an aspect ratio calculator. It reduces any margin of error. Check the what is aspect ratio post.
