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. Enter a desired width for a 16:9 HD size video to get the width and height needed to maintain the aspect ratio when resizing your original video.

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.
