OnePlus 9 & 11 viewport size

OnePlus 9 / 11 (2021) lays web pages out at 412 × 919 CSS pixels with a pixel ratio of 2.625.

Browser bars and the visible area

The viewport height is the whole screen, but Chrome on Android keeps part of it for its own interface. In portrait about 80 px at the top (status bar and address bar) and 16 px at the bottom (navigation bar) are covered, leaving roughly 412 × 823 CSS px for the page when it first opens. In landscape the bars take about 80 px.

That is why 100vh can be taller than what people see. Use 100svh for the smallest visible height, 100dvh for the current one, and keep the most important content and buttons within the first 823 px.

Testing on the OnePlus 9 & 11

Android phones render with Chromium, the engine behind Chrome. Pixel ratios like 2.625 mean thin borders and small images can look blurry or uneven — check them at the real ratio. See how to test a website on Android.
