Screen Dimensions

Apple iPhone X screen size is 5.8 inch with ~ 82.9% body ratio of actual device size. Physical dimensions for Apple iPhone X device is 5.65 x 2.79 x 0.30 INCH or ( 143.6 x 70.9 x 7.7 MM).

Displaying of Units are in this order "Height x Width x Thickness"

Screen Pixel Density and CSS Pixel Ratio

"Pixel" is smallest unit/element of any display.

The total number of pixels that fit into an inch is referred to as "Screen Density" or "Pixel Density" and it measured as "Pixels Per Inch".
Pixel Desnsity have limits to display Pixels Per Inch depends on different screen sizes. When number of pixels per inch increases than it's screen-size limit, the Display resolution will increase but actual device width/height in pixels remain same. Actual device pixels are known as Device Independent Pixels or CSS Pixel Ratio.


Apple iPhone X resolution is 1125 x 2436 PX with ~ 458 pixel desnsity.
Apple iPhone X viewport size is 375 x 812 PX with ~ 153 actual pixel density, which means it have 3 xxhdpi display pixel density.

Screen Resolution and Viewport

The sum of pixels which are displaying on a device is called as "Screen Resolution". and sum of actual pixels of any device is reffered to as "Viewport".

Apple iPhone X have 5.8" physical screen size and its resolution is about 1125 x 2436 Pixels with approximately 458 PPI pixel density. Apple iPhone X has viewport size 375 x 812 Pixels and its pixel ratio is about 3.
