Google Pixel 9 Pro / Pro XL: Screen Size & CSS Viewport

The Google Pixel 9 Pro line brought 3000 nits peak brightness to Android — the first time Google reached this brightness level — combined with a contrast ratio exceeding 2,000,000:1. Together these specs create the most capable display for reading web content in challenging lighting conditions that Google has ever shipped.

The CSS viewport of 412×915 is the primary Android developer reference width. Google's own Material Design guidelines, Lighthouse performance audits, and Core Web Vitals measurements are all calibrated against this viewport. Any responsive design improvement you make for 412px has a direct, measurable effect on how Google's own tooling scores your site.

The LTPO 1–120 Hz adaptive refresh rate means the display runs at as low as 1 Hz for static content and scales up to 120 Hz for fast motion. CSS animations that trigger at 120 Hz look exceptional here, but animations with frame-rate-sensitive logic (using requestAnimationFrame with elapsed-time calculations) should be tested at both ends of this range. Static pages that have background CSS animations may incidentally prevent the display from dropping below 60 Hz, consuming battery unnecessarily for users who are not actively scrolling.
