Why test your site on Samsung Galaxy S24?

Narrow viewport

With only 360 pixels wide, Samsung Galaxy S24 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 Samsung Galaxy S24 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, Samsung Galaxy S24 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 Samsung Galaxy S24

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.

  • 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 Samsung Galaxy S24

3

The device pixel ratio of Samsung Galaxy S24 is 3.

Your images should therefore be exported 3 times larger than their display size, otherwise they will appear softened on this screen.

Manufacturer resolution of Samsung Galaxy S24

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
  • 2340 pixels in height
  • 19.5:9 Screen ratio

Media queries and code snippets for Samsung Galaxy S24

These snippets are generated from the exact characteristics of Samsung Galaxy S24. Copy them directly into your stylesheet or configuration.

CSS media query

@media only screen and (min-width: 360px) and (max-width: 779px) {
  /* Samsung Galaxy S24 */
}

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 Samsung Galaxy S24.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'samsung-galaxy-s24-2024': '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 Samsung Galaxy S24 to use its CSS viewport and not a simulated width of 980 pixels.

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