How to get the screen size (width, height) in JavaScript

Learn, how to get the device width and height in JavaScript

Using availHeight and availWidth

We can use the screen.availWidth and screen.availHeight properties to get the screen size of a device in pixels.

Example:

window.screen.availWidth; // 1440

window.screen.availWidth; // 877

Note: The availWidth, availHeight properties excludes the device taskbar.

If you want to get the total width and height of the user’s screen including taskbar, you can use the screen.width and screen.height properties.

window.screen.width; // 1440

window.screen.height; // 900
