CSS for the Samsung Galaxy S8+

Target this screen size in CSS (portrait):

@media (max-width: 360px) {
  /* Samsung Galaxy S8+ and smaller */
}
@media (min-resolution: 4dppx) {
  /* high-density screens: serve sharper images */
}

Design for ranges, not single devices: many phones share the same viewport width (for example 360 px). The Samsung Galaxy A55 and Moto G4 use it too.

Frequently asked questions

What is the viewport size of the Samsung Galaxy S8+?

360 × 740 CSS pixels in portrait and 740 × 360 in landscape.

What is the screen resolution of the Samsung Galaxy S8+?

About 1440 × 2960 physical pixels: the viewport multiplied by the device pixel ratio of 4.

Why is the viewport smaller than the screen resolution?

Phones pack several physical pixels into one CSS pixel (the device pixel ratio) so text stays readable. Websites lay out in CSS pixels; images can use the extra pixels for sharpness.
