AspectCalculator

AspectCalculator is a user-friendly and intuitive piece of software whose main purpose resides in offering you the means of correctly determining the best width and height for the videos you wish to convert or resize.

No setup required

Since it is a portable tool, you have no need to install it on your system, as you can just decompress the downloaded archive and run the executable by double clicking it.
Consequently, this means it can be stored and run from a removable storage device, like a USB stick or other similar drives, using it on all compatible systems, without having to wait around for the setup to complete.

Obtain the proper aspect ratio value for converting or resizing movies

AspectCalculator displays a simple, non-adjustable window as its interface, allowing you to learn the video aspect ratio you need right away. It features two main gliders that let you manually define the width and height values in pixels.
At the same time, the application enables you to just input the value you need in the text box. Given that the best dimensions should be divisible by eight, the tool automatically performs this calculation and informs you of the result, so you can make sure it suits your particular needs.
AspectCalculator also generates the aspect ratio value (width / height). Each result can be copied to clipboard by pressing the dedicated button in the interface. Moreover, the program is able to provide you with the precise string that can be used when processing videos with FFmpeg or x264 encoders, copying it to your clipboard at the click of a button.

A handy video aspect ratio calculator

All in all, AspectCalculator proves to be a useful and effective utility that you can rely on for quickly determining the best width and height ratio for movie conversion or resizing tasks, with little to no effort entailed.
