Why test your site on Huawei Y9 Prime?

Narrow viewport

With only 360 pixels wide, Huawei Y9 Prime 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 Y9 Prime 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 Y9 Prime 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 Y9 Prime

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.

  • 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 Y9 Prime

3

The device pixel ratio of Huawei Y9 Prime is 3.

In other words, a 1-pixel square in CSS occupies 3 pixels on the panel. An image exported at actual size will appear blurry.

Manufacturer resolution of Huawei Y9 Prime

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
  • 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 Y9 Prime

These snippets are generated from the exact characteristics of Huawei Y9 Prime. Copy them directly into your stylesheet or configuration.

CSS media query

Targets screens whose width matches that of Huawei Y9 Prime and models of the same format.

@media only screen and (min-width: 360px) and (max-width: 779px) {
  /* Huawei Y9 Prime */
}

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 Y9 Prime.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'huawei-y9-prime': '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 Y9 Prime to use its CSS viewport and not a simulated width of 980 pixels.

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

Mobile FIRST does not yet include Huawei Y9 Prime, 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 Y9 Prime Select Huawei Y9 Prime 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 Y9 Prime

These 10 devices share exactly the viewport of 360 x 780 pixels and the 3x density of Huawei Y9 Prime. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.

What is the screen resolution of Huawei Y9 Prime?

The panel of Huawei Y9 Prime 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 Y9 Prime?

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

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 Y9 Prime 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 Y9 Prime?

A media query on the exact width targets Huawei Y9 Prime: @media only screen and (min-width: 360px). Combine it with the pixel density to precisely target this model and those sharing its format.
