Why test your site on Huawei Y9s?

Narrow viewport

With only 360 pixels wide, Huawei Y9s 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 Huawei Y9s 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, Huawei Y9s 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 Huawei Y9s

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 Huawei Y9s

3

The device pixel ratio of Huawei Y9s is 3.

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

Manufacturer resolution of Huawei Y9s

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 Huawei Y9s

These snippets are generated from the exact characteristics of Huawei Y9s. Copy them directly into your stylesheet or configuration.

CSS media query

Targets screens whose width matches that of Huawei Y9s and models of the same format.

@media only screen and (min-width: 360px) and (max-width: 779px) {
  /* Huawei Y9s */
}

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 Huawei Y9s.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'huawei-y9s': '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 Huawei Y9s to use its CSS viewport and not a simulated width of 980 pixels.

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

Free Huawei Y9s simulator

Mobile FIRST does not yet include Huawei Y9s, 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 Huawei Y9s Select Huawei Y9s 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 Huawei Y9s

These 10 devices share exactly the viewport of 360 x 780 pixels and the 3x density of Huawei Y9s. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.

Comparison with similar models

The neighboring formats of Huawei Y9s are the ones to test right after, as they reveal poorly placed breakpoints.

Frequently asked questions about Huawei Y9s

What is the CSS viewport resolution of Huawei Y9s?

The CSS viewport of Huawei Y9s 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 Huawei Y9s?

The device pixel ratio of Huawei Y9s 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 Huawei Y9s?

The panel of Huawei Y9s 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 Huawei Y9s?

10 other models share exactly the viewport of 360 x 780 pixels and the 3x density of Huawei Y9s: Apple iPhone 12 Mini, Honor 8X, Honor 9X, Huawei Mate 20 Lite, Huawei Mate 30, Huawei P30 PRO, Huawei Y9 Prime, 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 Huawei Y9s without the device?

Install the Mobile FIRST extension on Chrome, Firefox, or Edge, then select Huawei Y9s. 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 Huawei Y9s, 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 Huawei Y9s?

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 Huawei Y9s 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 Huawei Y9s?

A media query on the exact width targets Huawei Y9s: @media only screen and (min-width: 360px). Combine it with the pixel density to precisely target this model and those sharing its format.
