How Can I Get Screen, Web Page, and Browser Window Dimensions Across Different Browsers?

Obtaining Screen, Web Page, and Browser Window Dimensions Across Major Browsers

To capture the dimensions of various screen and window elements in all major browsers, consider utilizing the following techniques:

Current Screen Dimensions

Access the screen object to retrieve screen width and height:

window.screen.height;
window.screen.width;

Current Web Page Dimensions

For HTML document size, utilize jQuery:

// Size of HTML document (similar to pageHeight/pageWidth)
$(document).height();
$(document).width();

Browser Window Dimensions

jQuery can also retrieve browser window dimensions:

// Size of browser viewport
$(window).height();
$(window).width();

Legacy Calculations

For legacy browsers, it was common to use a combination of window and document properties to obtain dimensions:

windowHeight = window.innerHeight || document.documentElement.clientHeight;
windowWidth = window.innerWidth || document.documentElement.clientWidth;
pageHeight = document.body.scrollHeight;
pageWidth = document.body.scrollWidth;
pageX = window.pageXOffset || document.documentElement.scrollLeft;
pageY = window.pageYOffset || document.documentElement.scrollTop;
screenHeight = window.screen.availHeight || window.screen.height;
screenWidth = window.screen.availWidth || window.screen.width;
screenX = window.screen.availLeft || window.screen.x;
screenY = window.screen.availTop || window.screen.y;
