Why test your site on Honor 9X?

Narrow viewport

With only 360 pixels wide, Honor 9X is among the most restrictive formats. This is where tables overflow, titles break poorly, and buttons become too small.

3x density

Each CSS pixel of Honor 9X is rendered by 3 physical pixels. Any image, icon, or font provided in simple resolution appears immediately blurry.

Very elongated screen

With a ratio of 19.5:9, Honor 9X displays a lot of height for little width. Sections designed in landscape become endless columns, and full-screen visuals are poorly cropped.

CSS viewport resolution of Honor 9X

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

  • 360 pixels in width
  • 780 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 Honor 9X

3

The device pixel ratio of Honor 9X is 3.

Each CSS pixel is thus rendered by 3 physical pixels, making any image provided in simple resolution immediately visible.

Manufacturer resolution of Honor 9X

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
  • 2340 pixels in height
  • 19.5:9 Screen ratio

391 pixels per inch (ppi) · 6.6 inches diagonal, or 16.7 cm

Media queries and code snippets for Honor 9X

These snippets are generated from the exact characteristics of Honor 9X. Copy them directly into your stylesheet or configuration.

CSS media query

Targets screens whose width matches that of Honor 9X and models of the same format.

@media only screen and (min-width: 360px) and (max-width: 779px) {
  /* Honor 9X */
}

Density media query

Serves high-resolution images to screens of at least 3x.

@media only screen and (-webkit-min-device-pixel-ratio: 3),
       only screen and (min-resolution: 288dpi) {
  /* High-density images and icons */
}

Tailwind configuration

Adds a named breakpoint at the exact width of Honor 9X.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'honor-9x': '360px'
    }
  }
}

JavaScript detection

Detects format and density client-side.

const isDeviceWidth = window.matchMedia('(min-width: 360px)').matches;
const isHighDensity = window.devicePixelRatio >= 3;

Meta viewport tag

Essential for Honor 9X to use its CSS viewport and not a simulated width of 980 pixels.

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

Free Honor 9X simulator

Mobile FIRST does not yet include Honor 9X, 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 Honor 9X Select Honor 9X 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 Honor 9X

These 10 devices share exactly the viewport of 360 x 780 pixels and the 3x density of Honor 9X. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.

Frequently asked questions about Honor 9X

What is the CSS viewport resolution of Honor 9X?

The CSS viewport of Honor 9X measures 360 pixels wide and 780 pixels high. This is the width to use for defining your media queries, not the manufacturer's resolution.

What is the pixel density of Honor 9X?

The device pixel ratio of Honor 9X is 3. Each CSS pixel is thus displayed by 3 physical pixels, requiring you to provide your images in 3x to keep them sharp.

What is the screen resolution of Honor 9X?

The panel of Honor 9X displays 1080 x 2340 physical pixels. This is the value reported by most analytics tools, while your CSS works on a viewport of 360 x 780 pixels.

Which devices have the same viewport as Honor 9X?

10 other models share exactly the viewport of 360 x 780 pixels and the 3x density of Honor 9X: Apple iPhone 12 Mini, Honor 8X, Huawei Mate 20 Lite, Huawei Mate 30, Huawei P30 PRO, Huawei Y9 Prime, Huawei Y9s, Samsung Galaxy S22, Samsung Galaxy S22+, Samsung Galaxy S24. A rendering validated on one is valid on all others.

How to test my site on Honor 9X without the device?

Install the Mobile FIRST extension on Chrome, Firefox, or Edge, then select Honor 9X. Your page displays in a viewport of 360 x 780 pixels with the corresponding mobile User-Agent, in two clicks and for free.

What is the difference with Chrome DevTools' responsive mode?

DevTools resizes the window and applies partial emulation. Mobile FIRST additionally applies the User-Agent of Honor 9X, touch events, scroll behavior, and the actual appearance of the device, and allows capturing directly usable images and videos.

Can I test a localhost address on Honor 9X?

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 Honor 9X 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 Honor 9X?

A media query on the exact width targets Honor 9X: @media only screen and (min-width: 360px). Combine it with the pixel density to precisely target this model and those sharing its format.
