How to get the size of screen, current web page and browser window using jQuery?

Last Updated : 23 Apr, 2019

jQuery can be used to get the dimensions of the current page. The dimensions include the screen, viewport and document height, and width.

Getting the window dimensions: Window size is the size of the browser window. This is the size that changes when the browser is resized. The windows height and width can be accessed with the height() and width() method after selecting the window object.
Getting the document dimensions: Document size is the size of the HTML document. The documents height and width can be accessed with the height() and width() method after selecting the document object.
Getting the screen dimensions: Screen size is the total size of the user's screen. The screen's height and width can be accessed with the height and width property.

Example:

html

<!DOCTYPE html>
<head>
    <title>

        web page and browser window using
        jQuery?
