Image Aspect Ratio Calculator

The Image Aspect Ratio Calculator is a fast and simple tool built with pure HTML, CSS, and JavaScript. Just input your image’s width and height, and the tool will automatically calculate the aspect ratio in both traditional format (like 16:9) and decimal format (like 1.78).

This tool is ideal for web designers, developers, photographers, and content creators who want to ensure images and videos are scaled properly for responsive layouts, UI components, or media frames. Whether you’re prepping for a web project, presentation, or social media content, this tool helps maintain clean visuals and accurate proportions.

No frameworks, no bloat — just a reliable utility you can use directly in your browser or embed on your own site.
