Why test your site on OnePlus 8?

Very elongated screen

With a ratio of 20:9, OnePlus 8 displays a lot of height for little width. Sections designed in landscape become endless columns, and full-screen visuals are poorly cropped.

2.625x density

With a density of 2.625x, OnePlus 8 provides a useful benchmark to ensure your images remain sharp without serving unnecessarily large files.

Actual media queries

The 412 x 915 pixels viewport of OnePlus 8 rarely matches the round breakpoints of frameworks. It is precisely between these values that layouts break.

CSS viewport resolution of OnePlus 8

This is the width your CSS considers. All your breakpoints and media queries compare to this value, not the number of physical pixels on the panel.

  • 412 pixels in width
  • 915 pixels in height

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 8

2.625

The device pixel ratio of OnePlus 8 is 2.625.

Your images should therefore be exported 2.625 times larger than their display size, otherwise they will appear softened on this screen.

Manufacturer resolution of OnePlus 8

This is the actual number of pixels on the panel. This value does not affect your layouts, but it's the one reported by technical specifications and most analytics tools.

  • 1080 pixels in width
  • 2400 pixels in height
  • 20:9 Screen ratio

402 pixels per inch (ppi) · 6.6 inches diagonal, or 16.6 cm

Media queries and code snippets for OnePlus 8

These snippets are generated from the exact characteristics of OnePlus 8. Copy them directly into your stylesheet or configuration.

CSS media query

Targets screens whose width matches that of OnePlus 8 and models of the same format.

@media only screen and (min-width: 412px) and (max-width: 914px) {
  /* OnePlus 8 */
}

Density media query

Serves high-resolution images to screens of at least 2.625x.

@media only screen and (-webkit-min-device-pixel-ratio: 2.625),
       only screen and (min-resolution: 252dpi) {
  /* High-density images and icons */
}

Tailwind configuration

Adds a named breakpoint at the exact width of OnePlus 8.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'oneplus-8': '412px'
    }
  }
}

JavaScript detection

Detects format and density client-side.

const isDeviceWidth = window.matchMedia('(min-width: 412px)').matches;
const isHighDensity = window.devicePixelRatio >= 2.625;

Meta viewport tag

Essential for OnePlus 8 to use its CSS viewport and not a simulated width of 980 pixels.

<meta name="viewport" content="width=device-width, initial-scale=1">

Free OnePlus 8 simulator

Mobile FIRST does not yet include OnePlus 8, 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 8 Select OnePlus 8 from the list of devices. The viewport switches to 412 x 915 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 8

These 4 devices share exactly the viewport of 412 x 915 pixels and the 2.625x density of OnePlus 8. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.

Yes. The extension works on any URL open in your browser, including localhost:3000, 127.0.0.1, or a password-protected pre-production environment.

Do you need to buy a OnePlus 8 to test your site?

No. The simulation covers the vast majority of development needs at no cost. A final test on a real device is still recommended before critical production deployment, but it's no longer necessary for each iteration.

Which media query to use to target OnePlus 8?

A media query on the exact width targets OnePlus 8: @media only screen and (min-width: 412px). Combine it with the pixel density to precisely target this model and those sharing its format.
