Device Size

MacBook Pro 2018 have 15.4 inch screen . Physical dimensions for MacBook Pro 15″ 2018 device is 13.75 x 0.61 x 9.48 INCH or ( 34.93 x 1.55 x 24.07 CM).

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

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.

MacBook Pro 15″ 2018 have ~ 220 pixel density and actual pixel density is about ~ 112 so it have 2 xhdpi 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".

MacBook Pro 15″ 2018 have 15.4" physical screen size with IPS technology and it's native resolution is 2880 x 1800 Pixels with approximately 220 PPI pixel density. MacBook Pro 15″ 2018 has viewport size 1440 x 900 Pixels and its pixel ratio is about 2.

    /* Retina styles here */
}
                                

Retina is actually based upon device pixel ratio. Devices mostly have 2x or 3x display so you can use general retina media queries to display high resolution content on all kind of devices. Retina 2x and Retina 3x media queries given below:
