What is an Aspect Ratio Calculator?
An aspect ratio calculator is a tool that helps you determine the dimensions of an image or video based on a specific ratio (like 16:9 for widescreen video or 4:5 for social media). You can lock either the width or the height and adjust the other dimension, and the calculator will automatically calculate the corresponding value to maintain the chosen aspect ratio. It's essential for designers, video editors, and anyone working with digital media.
Common uses include social media images, video editing, web design, and screen layouts.
