About this site
Aspect Ratio Calculator Pro is a small collection of free calculators for people who work with screens, video and images: the aspect ratio calculator, an inches to pixels converter, an image resolution checker and a screen resolution check, plus guides to the sizes behind them.
Built to be quick and private
Every tool runs in your browser. Numbers you type and images you check are not sent anywhere. The pages load no third-party scripts, fonts, ads or trackers.
Who is behind it
The site is written and maintained by the Aspect Ratio Calculator Pro Editorial Team. Guides are researched and drafted with AI assistance, and every figure is checked against the linked sources before it goes live. The math in each tool is covered by automated tests. Details are in the editorial policy.
