Why this exists

For years, these numbers were a mystery for developers, designers, and testers. We parroted screen sizes from spec sheets while users were experiencing something completely different in the browser — and nobody had those viewports in one place.

I measure those scenarios on real hardware and simulators and publish them here — viewports you can copy into DevTools, use in Figma, and test automation. The dataset keeps growing and updates when OS or browser UI changes.
