OnePlus 8T: CSS viewport of 412 × 914 px, resolution and responsive test

Why test your site on OnePlus 8T?

CSS viewport resolution of OnePlus 8T

This resolution is what your stylesheet actually manipulates. It determines the applied breakpoint, the number of displayed columns, and the size of your images.

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 8T

The device pixel ratio of OnePlus 8T is 2.625. Each CSS pixel is thus rendered by 2.625 physical pixels, making any image provided in simple resolution immediately visible.

Manufacturer resolution of OnePlus 8T

This is the number of physical pixels on the screen, as announced by the manufacturer. Useful for preparing your image exports, useless for your media queries.

• 1080 pixels in width
• 2400 pixels in height
• 402 pixels per inch (ppi)
• 6.6 inches diagonal, or 16.6 cm
• Screen ratio of 20:9

const isHighDensity = window.devicePixelRatio >= 2.625;

Free OnePlus 8T simulator

Mobile FIRST does not yet include OnePlus 8T, 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 8T — Select OnePlus 8T from the list of devices. The viewport switches to 412 x 914 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 OnePlus 8T

These 6 devices share exactly the viewport of 412 x 914 pixels and the 2.625x density of OnePlus 8T. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.

• OnePlus 7T
• Samsung Galaxy A51
• Samsung Galaxy A70s
• Samsung Galaxy A71
• Samsung Galaxy S10 Lite
• Samsung Galaxy S20 FE
