Huawei Mate 20 Pro: CSS viewport of 360 × 780 px, resolution and responsive test

Why test your site on Huawei Mate 20 Pro?

CSS viewport resolution of Huawei Mate 20 Pro

This is the resolution that interests designers and developers the most, as it determines breakpoints and the definition of media queries. In practice, it's the only one mentioned in a stylesheet.

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.

Pixel density of Huawei Mate 20 Pro

The device pixel ratio of Huawei Mate 20 Pro is 4. In other words, a 1-pixel square in CSS occupies 4 pixels on the panel. An image exported at actual size will appear blurry.

Manufacturer resolution of Huawei Mate 20 Pro

This resolution is the hardware's. It explains the display's sharpness, but it's never the one to target in a media query.

• 1440 pixels in width
• 3120 pixels in height
• 538 pixels per inch (ppi)
• 6.4 inches diagonal, or 16.2 cm
• Screen ratio of 19.5:9

Mobile FIRST does not yet include Huawei Mate 20 Pro, but a model with the same format is available. You can already validate your breakpoints and display density.

This is where the difference with Chrome DevTools' responsive mode is seen: DevTools resizes a window, the extension replicates the device's browser and allows exporting shareable screenshots and videos.

1. 01 Install the extension — Add Mobile FIRST to Chrome, Firefox, or Edge. Installation is free and requires no account.
2. 02 Open the page to test — Go to the URL to check, including a local address like localhost:3000.
3. 03 Choose Huawei Mate 20 Pro — Select Huawei Mate 20 Pro from the list of devices. The viewport switches to 360 x 780 pixels, and the mobile User-Agent is applied.
4. 04 Check rendering — Scroll, change orientation, test your forms, then capture an image or video to share.

Models sharing the format of Huawei Mate 20 Pro

These 1 devices share exactly the viewport of 360 x 780 pixels and the 4x density of Huawei Mate 20 Pro. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.
