What is the best way to calculate precise pixel dimensions for mobile devices?

Upon inspecting the browser's developer tool, it indicates that the resolution of an iPhone X is 375*812, although this may not be the actual resolution. While CSS pixels do not always align perfectly with display resolution, the question remains - If I adjust the width and height of HTML elements to match the simulated iPhone display in the developer tools, will the view appear the same on an actual iPhone?

Answer №1

A helpful tip is to utilize CSS media queries if you want to avoid manually coding resolution values for various devices, making your work much more efficient.

Here's an example:

/* Extra small devices (phones, 600px and down) */
@media only screen and (max-width: 600px) {...}

/* Small devices (portrait tablets and large phones, 600px and up) */
@media only screen and (min-width: 600px) {...}

/* Medium devices (landscape tablets, 768px and up) */
@media only screen and (min-width: 768px) {...}

/* Large devices (laptops/desktops, 992px and up) */
@media only screen and (min-width: 992px) {...}

/* Extra large devices (large laptops and desktops, 1200px and up) */
@media only screen and (min-width: 1200px) {...}
