Why Test on Honor 400 Pro?
Viewport
Its larger viewport stresses layout adaptability and content flow.
Pixel Density (DPR)
High DPR highlights image sharpness and scaling errors.
Performance & Animations
Fast UI interactions reveal animation performance issues.
Viewport Size (CSS Resolution)
The CSS viewport defines how media queries, layout breakpoints, and responsive components behave.
For Honor 400 Pro, the CSS viewport measures:
- Width: 427 px
- Height: 933 px
ℹ️ The visible height can vary slightly depending on the browser UI (Safari, Chrome, etc.).
Some analytics platforms only display the physical screen resolution (see below) instead of the CSS viewport size, so keep that in mind when interpreting results.
To see exactly how this viewport behaves in real conditions, you can simulate Honor 400 Pro directly in your browser using Phone Simulator.

Pixel Density (Device Pixel Ratio)
Honor 400 Pro has a device pixel ratio of 3.
Each CSS pixel is rendered using 3 physical pixels, resulting in sharper text and images.
For CSS targeting:
@media only screen and (-webkit-min-device-pixel-ratio: 3) {
/* High-DPI specific styles */
}In JavaScript:
window.devicePixelRatio;
// returns: 3Physical Screen Resolution
Physical resolution refers to the actual number of hardware pixels on the display. While it does not affect CSS layouts, it is commonly shown in analytics and device specifications.
- Width: 1280 px
- Height: 2800 px
ℹ️ Physical resolution is not used for CSS layouts but is often shown in analytics tools.
