OnePlus 6T: CSS viewport of 412 × 892 px, resolution and responsive test

Why test your site on OnePlus 6T?

CSS viewport resolution of OnePlus 6T

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 6T

The device pixel ratio of OnePlus 6T is 2.625. In other words, a 1-pixel square in CSS occupies 2.625 pixels on the panel. An image exported at actual size will appear blurry.

Manufacturer resolution of OnePlus 6T

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

• 1080 pixels in width
• 2340 pixels in height
• 402 pixels per inch (ppi)
• 6.4 inches diagonal, or 16.3 cm
• Screen ratio of 19.5:9

Media queries and code snippets for OnePlus 6T

@media only screen and (min-width: 412px) and (max-width: 891px) {

}

@media only screen and (-webkit-min-device-pixel-ratio: 2.625),

}

// tailwind.config.js
module.exports = {

Free OnePlus 6T simulator

Mobile FIRST does not yet include OnePlus 6T, 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 6T — Select OnePlus 6T 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.

Models sharing the format of OnePlus 6T

These 5 devices share exactly the viewport of 412 x 892 pixels and the 2.625x density of OnePlus 6T. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.

• OnePlus 7
• Samsung A50
• Samsung Galaxy A17
• Samsung Galaxy A30
