Why test your site on Microsoft Surface Duo?

Two orientations to validate

On Microsoft Surface Duo, your visitors constantly switch from portrait to landscape. Both orientations correspond to two different breakpoints, and the second is almost always the least tested.

2.5x density

With a density of 2.5x, Microsoft Surface Duo provides a useful benchmark to ensure your images remain sharp without serving unnecessarily large files.

Wifi connection

This model is representative of Wifi usage. Testing on it ensures your page remains usable when images and fonts load slowly.

CSS viewport resolution of Microsoft Surface Duo

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.

  • 1114 pixels in width
  • 705 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 Microsoft Surface Duo

2.5

The device pixel ratio of Microsoft Surface Duo is 2.5.

In other words, a 1-pixel square in CSS occupies 2.5 pixels on the panel. An image exported at actual size will appear blurry.

Manufacturer resolution of Microsoft Surface Duo

This resolution is the hardware's. It explains the display's sharpness, but it's never the one to target in a media query.

  • 2785 pixels in width
  • 1762 pixels in height
  • 14:9 Screen ratio

588 pixels per inch (ppi) · 5.6 inches diagonal, or 14.2 cm

  /* Microsoft Surface Duo */
}

Density media query

Serves high-resolution images to screens of at least 2.5x.

@media only screen and (-webkit-min-device-pixel-ratio: 2.5),
       only screen and (min-resolution: 240dpi) {
  /* High-density images and icons */
}

Tailwind configuration

module.exports = {
  theme: {
    screens: {
      'microsoft-surface-duo': '1114px'
    }
  }
}

JavaScript detection

Detects format and density client-side.

const isDeviceWidth = window.matchMedia('(min-width: 1114px)').matches;
const isHighDensity = window.devicePixelRatio >= 2.5;

Meta viewport tag

Essential for Microsoft Surface Duo to use its CSS viewport and not a simulated width of 980 pixels.

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