Why test your site on Xiaomi 12 2022?

Narrow viewport

With only 360 pixels wide, Xiaomi 12 2022 is among the most restrictive formats. This is where tables overflow, titles break poorly, and buttons become too small.

3x density

Each CSS pixel of Xiaomi 12 2022 is rendered by 3 physical pixels. Any image, icon, or font provided in simple resolution appears immediately blurry.

Very elongated screen

With a ratio of 20:9, Xiaomi 12 2022 displays a lot of height for little width. Sections designed in landscape become endless columns, and full-screen visuals are poorly cropped.

CSS viewport resolution of Xiaomi 12 2022

This is the width your CSS considers. All your breakpoints and media queries compare to this value, not the number of physical pixels on the panel.

  • 360 pixels in width
  • 800 pixels in height

The height remains indicative: Safari, Chrome, and other mobile browsers reduce the visible area with their address bar, which folds on scroll.

Be cautious when analyzing your statistics: some tools only report the manufacturer resolution, never the CSS viewport presented here.
