Why test your site on Sony Xperia X?

Narrow viewport

With only 360 pixels wide, Sony Xperia X 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 Sony Xperia X is rendered by 3 physical pixels. Any image, icon, or font provided in simple resolution appears immediately blurry.

Older hardware

The hardware of Sony Xperia X dates from 2016. Its processor makes costly animations, heavy scripts, and display times visible that recent devices mask.

CSS viewport resolution of Sony Xperia X

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
  • 640 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 Sony Xperia X

3

The device pixel ratio of Sony Xperia X is 3.

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

Manufacturer resolution of Sony Xperia X

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
  • 1920 pixels in height
  • 16:9 Screen ratio

441 pixels per inch (ppi) · 5 inches diagonal, or 12.7 cm

Media queries and code snippets for Sony Xperia X

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

CSS media query

Targets screens whose width matches that of Sony Xperia X and models of the same format.

@media only screen and (min-width: 360px) and (max-width: 639px) {
  /* Sony Xperia X */
}

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 Sony Xperia X.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'sony-xperia-x': '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 Sony Xperia X to use its CSS viewport and not a simulated width of 980 pixels.

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

Free Sony Xperia X simulator

Mobile FIRST does not yet include Sony Xperia X, 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 Sony Xperia X Select Sony Xperia X from the list of devices. The viewport switches to 360 x 640 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 Sony Xperia X

These 5 devices share exactly the viewport of 360 x 640 pixels and the 3x density of Sony Xperia X. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.
