OnePlus 7 Pro: CSS viewport of 412 × 892 px, resolution and responsive test

Why test your site on OnePlus 7 Pro?

CSS viewport resolution of OnePlus 7 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 OnePlus 7 Pro

The device pixel ratio of OnePlus 7 Pro is 3.5. In other words, a 1-pixel square in CSS occupies 3.5 pixels on the panel. An image exported at actual size will appear blurry.

Manufacturer resolution of OnePlus 7 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
• 516 pixels per inch (ppi)
• 6.7 inches diagonal, or 16.9 cm
• Screen ratio of 19.5:9

Mobile FIRST does not yet include OnePlus 7 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 OnePlus 7 Pro — Select OnePlus 7 Pro from the list of devices. The viewport switches to 412 x 892 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.
