How can I get windowWidth, windowHeight, pageWidth, pageHeight, screenWidth, screenHeight, pageX, pageY, screenX, screenY which will work in all major browsers?
You can get the size of the window or document with jQuery:
// Size of browser viewport.
$(window).height();
$(window).width();
// Size of HTML document (same as pageHeight/pageWidth in screenshot).
$(document).height();
$(document).width();
For screen size you can use the screen object:
window.screen.height;
window.screen.width;
This has everything you need to know: Get viewport/window size
but in short:
var win = window,
doc = document,
docElem = doc.documentElement,
body = doc.getElementsByTagName('body')[0],
x = win.innerWidth || docElem.clientWidth || body.clientWidth,
y = win.innerHeight|| docElem.clientHeight|| body.clientHeight;
alert(x + ' × ' + y);

Please stop editing this answer. It's been edited 22 times now by different people to match their code format preference. It's also been pointed out that this isn't required if you only want to target modern browsers - if so you only need the following:
const width = window.innerWidth || document.documentElement.clientWidth ||
document.body.clientWidth;
const height = window.innerHeight|| document.documentElement.clientHeight||
document.body.clientHeight;
console.log(width, height);
Here is a cross browser solution with pure JavaScript (Source):
var width = window.innerWidth
|| document.documentElement.clientWidth
|| document.body.clientWidth;
var height = window.innerHeight
|| document.documentElement.clientHeight
|| document.body.clientHeight;
A non-jQuery way to get the available screen dimension. window.screen.width/height has already been put up, but for responsive webdesign and completeness sake I think its worth to mention those attributes:
alert(window.screen.availWidth);
alert(window.screen.availHeight);
http://www.quirksmode.org/dom/w3c_cssom.html#t10 :
availWidth and availHeight - The available width and height on the
screen (excluding OS taskbars and such).
But when we talk about responsive screens and if we want to handle it using jQuery for some reason,
window.innerWidth, window.innerHeight
gives the correct measurement. Even it removes the scroll-bar's extra space and we don't need to worry about adjusting that space :)

I am surprised that question have about 10 years and it looks like so far nobody has given a full answer (with 10 values) yet. So I carefully analyse OP question (especially picture) and have some remarks
center of coordinate system (0,0) is in the viewport (browser window without bars and main borders) top left corner and axes are directed to right and down (what was marked on OP picture) so the values of pageX, pageY, screenX, screenY must be negative (or zero if page is small or not scrolled)
for screenHeight/Width OP wants to count screen height/width including system menu bar (eg. in MacOs) - this is why we NOT use .availWidth/Height (which not count it)
for windowWidth/Height OP don't want to count size of scroll bars so we use .clientWidth/Height
the screenY - in below solution we add to position of top left browser corner (window.screenY) the height of its menu/tabls/url bar). But it is difficult to calculate that value if download-bottom bar appears in browser and/or if developer console is open on page bottom - in that case this value will be increased of size of that bar/console height in below solution. Probably it is impossible to read value of bar/console height to make correction (without some trick like asking user to close that bar/console before measurements...)
pageWidth - in case when pageWidth is smaller than windowWidth we need to manually calculate size of <body> children elements to get this value (we do example calculation in contentWidth in below solution - but in general this can be difficult for that case)
for simplicity I assume that <body> margin=0 - if not then you should consider this values when calculate pageWidth/Height and pageX/Y
function sizes() {
const contentWidth = [...document.body.children].reduce(
(a, el) => Math.max(a, el.getBoundingClientRect().right), 0)
- document.body.getBoundingClientRect().x;
return {
windowWidth: document.documentElement.clientWidth,
windowHeight: document.documentElement.clientHeight,
pageWidth: Math.min(document.body.scrollWidth, contentWidth),
pageHeight: document.body.scrollHeight,
screenWidth: window.screen.width,
screenHeight: window.screen.height,
pageX: document.body.getBoundingClientRect().x,
pageY: document.body.getBoundingClientRect().y,
screenX: -window.screenX,
screenY: -window.screenY - (window.outerHeight-window.innerHeight),
}
}
// TEST
function show() {
console.log(sizes());
}
body { margin: 0 }
.box { width: 3000px; height: 4000px; background: red; }
<div class="box">
CAUTION: stackoverflow snippet gives wrong values for screenX-Y,
but if you copy this code to your page directly the values will be right<br>
<button onclick="show()" style="">CALC</button>
</div>
I test it on Chrome 83.0, Safari 13.1, Firefox 77.0 and Edge 83.0 on MacOs High Sierra

You can also get the WINDOW width and height, avoiding browser toolbars and other stuff. It is the real usable area in browser's window.
To do this, use:
window.innerWidth and window.innerHeight properties (see doc at w3schools).
In most cases it will be the best way, in example, to display a perfectly centred floating modal dialog. It allows you to calculate positions on window, no matter which resolution orientation or window size is using the browser.
To check height and width of your current loaded page of any website using "console" or after clicking "Inspect".
step 1: Click the right button of mouse and click on 'Inspect' and then click 'console'
step 2: Make sure that your browser screen should be not in 'maximize' mode. If the browser screen is in 'maximize' mode, you need to first click the maximize button (present either at right or left top corner) and un-maximize it.
step 3: Now, write the following after the greater than sign ('>') i.e.
> window.innerWidth
output : your present window width in px (say 749)
> window.innerHeight
output : your present window height in px (say 359)
Complete guide related to Screen sizes
JavaScript
For height:
document.body.clientHeight // Inner height of the HTML document body, including padding
// but not the horizontal scrollbar height, border, or margin
screen.height // Device screen height (i.e. all physically visible stuff)
screen.availHeight // Device screen height minus the operating system taskbar (if present)
window.innerHeight // The current document's viewport height, minus taskbars, etc.
window.outerHeight // Height the current window visibly takes up on screen
// (including taskbars, menus, etc.)
Note: When the window is maximized this will equal screen.availHeight
For width:
document.body.clientWidth // Full width of the HTML page as coded, minus the vertical scroll bar
screen.width // Device screen width (i.e. all physically visible stuff)
screen.availWidth // Device screen width, minus the operating system taskbar (if present)
window.innerWidth // The browser viewport width (including vertical scroll bar, includes padding but not border or margin)
window.outerWidth // The outer window width (including vertical scroll bar,
// toolbars, etc., includes padding and border but not margin)
Jquery
For height:
$(document).height() // Full height of the HTML page, including content you have to
// scroll to see
$(window).height() // The current document's viewport height, minus taskbars, etc.
$(window).innerHeight() // The current document's viewport height, minus taskbars, etc.
$(window).outerHeight() // The current document's viewport height, minus taskbars, etc.
For width:
$(document).width() // The browser viewport width, minus the vertical scroll bar
$(window).width() // The browser viewport width (minus the vertical scroll bar)
$(window).innerWidth() // The browser viewport width (minus the vertical scroll bar)
$(window).outerWidth() // The browser viewport width (minus the vertical scroll bar)

With the introduction of globalThis in ES2020 you can use properties like.
For screen size:
globalThis.screen.availWidth
globalThis.screen.availHeight
For Window Size
globalThis.outerWidth
globalThis.outerHeight
For Offset:
globalThis.pageXOffset
globalThis.pageYOffset
...& so on.
alert("Screen Width: "+ globalThis.screen.availWidth +"\nScreen Height: "+ globalThis.screen.availHeight)
If you need a truly bulletproof solution for the document width and height (the pageWidth and pageHeight in the picture), you might want to consider using a plugin of mine, jQuery.documentSize.
It has just one purpose: to always return the correct document size, even in scenarios when jQuery and other methods fail. Despite its name, you don't necessarily have to use jQuery – it is written in vanilla Javascript and works without jQuery, too.
Usage:
var w = $.documentWidth(),
h = $.documentHeight();
for the global document. For other documents, e.g. in an embedded iframe you have access to, pass the document as a parameter:
var w = $.documentWidth( myIframe.contentDocument ),
h = $.documentHeight( myIframe.contentDocument );
Update: now for window dimensions, too
Ever since version 1.1.0, jQuery.documentSize also handles window dimensions.
That is necessary because
$( window ).height() is buggy in iOS, to the point of being useless
$( window ).width() and $( window ).height() are unreliable on mobile because they don't handle the effects of mobile zooming.
jQuery.documentSize provides $.windowWidth() and $.windowHeight(), which solve these issues. For more, please check out the documentation.
I wrote a small javascript bookmarklet you can use to display the size. You can easily add it to your browser and whenever you click it you will see the size in the right corner of your browser window.
Here you find information how to use a bookmarklet
https://en.wikipedia.org/wiki/Bookmarklet
Bookmarklet
javascript:(function(){!function(){var i,n,e;return n=function(){var n,e,t;return t="background-color:azure; padding:1rem; position:fixed; right: 0; z-index:9999; font-size: 1.2rem;",n=i('<div style="'+t+'"></div>'),e=function(){return'<p style="margin:0;">width: '+i(window).width()+" height: "+i(window).height()+"</p>"},n.html(e()),i("body").prepend(n),i(window).resize(function(){n.html(e())})},(i=window.jQuery)?(i=window.jQuery,n()):(e=document.createElement("script"),e.src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js",e.onload=n,document.body.appendChild(e))}()}).call(this);
Original Code
The original code is in coffee:
(->
addWindowSize = ()->
style = 'background-color:azure; padding:1rem; position:fixed; right: 0; z-index:9999; font-size: 1.2rem;'
$windowSize = $('<div style="' + style + '"></div>')
getWindowSize = ->
'<p style="margin:0;">width: ' + $(window).width() + ' height: ' + $(window).height() + '</p>'
$windowSize.html getWindowSize()
$('body').prepend $windowSize
$(window).resize ->
$windowSize.html getWindowSize()
return
if !($ = window.jQuery)
# typeof jQuery=='undefined' works too
script = document.createElement('script')
script.src = 'http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js'
script.onload = addWindowSize
document.body.appendChild script
else
$ = window.jQuery
addWindowSize()
)()
Basically the code is prepending a small div which updates when you resize your window.
In some cases related with responsive layout $(document).height() can return wrong data that displays view port height only.
For example when some div#wrapper has height:100%, that #wrapper can be stretched by some block inside it. But it's height still will be like viewport height. In such situation you might use
$('#wrapper').get(0).scrollHeight
That represents actual size of wrapper.
I developed a library for knowing the real viewport size for desktops and mobiles browsers, because viewport sizes are inconsistents across devices and cannot rely on all the answers of that post (according to all the research I made about this) : https://github.com/pyrsmk/W
Sometimes you need to see the width/height changes while resizing the window and inner content.
For that I've written a little script that adds a log box that dynamicly monitors all the resizing and almost immediatly updates.
It adds a valid HTML with fixed position and high z-index, but is small enough, so you can:
use it on an actual site
use it for testing mobile/responsive
views
Tested on: Chrome 40, IE11, but it is highly possible to work on other/older browsers too ... :)

table.style.setProperty( 'margin-left', '-'+( table.clientWidth / 2 )+'px' );
setInterval( testSizes, 200 );
EDIT: Now styles are applied only to logger table element - not to all tables - also this is a jQuery-free solution :)
You can use the Screen object to get this.
The following is an example of what it would return:
Screen {
availWidth: 1920,
availHeight: 1040,
width: 1920,
height: 1080,
colorDepth: 24,
pixelDepth: 24,
top: 414,
left: 1920,
availTop: 414,
availLeft: 1920
}
To get your screenWidth variable, just use screen.width, same with screenHeight, you would just use screen.height.
To get your window width and height, it would be screen.availWidth or screen.availHeight respectively.
For the pageX and pageY variables, use window.screenX or Y. Note that this is from the VERY LEFT/TOP OF YOUR LEFT/TOP-est SCREEN. So if you have two screens of width 1920 then a window 500px from the left of the right screen would have an X value of 2420 (1920+500). screen.width/height, however, display the CURRENT screen's width or height.
To get the width and height of your page, use jQuery's $(window).height() or $(window).width().
Again using jQuery, use $("html").offset().top and $("html").offset().left for your pageX and pageY values.
here is my solution!
// innerWidth
const screen_viewport_inner = () => {
let w = window,
i = `inner`;
if (!(`innerWidth` in window)) {
i = `client`;
w = document.documentElement || document.body;
}
return {
width: w[`${i}Width`],
height: w[`${i}Height`]
}
};
// outerWidth
const screen_viewport_outer = () => {
let w = window,
o = `outer`;
if (!(`outerWidth` in window)) {
o = `client`;
w = document.documentElement || document.body;
}
return {
width: w[`${o}Width`],
height: w[`${o}Height`]
}
};
// style
const console_color = `
color: rgba(0,255,0,0.7);
font-size: 1.5rem;
border: 1px solid red;
`;
// testing
const test = () => {
let i_obj = screen_viewport_inner();
console.log(`%c screen_viewport_inner = \n`, console_color, JSON.stringify(i_obj, null, 4));
let o_obj = screen_viewport_outer();
console.log(`%c screen_viewport_outer = \n`, console_color, JSON.stringify(o_obj, null, 4));
};
// IIFE
(() => {
test();
})();
This how I managed to get the screen width in React JS Project:
If width is equal to 1680 then return 570 else return 200
var screenWidth = window.screen.availWidth;
<Label style={{ width: screenWidth == "1680" ? 570 : 200, color: "transparent" }}>a </Label>
Screen.availWidth
I am developing a React Application and want to Detect the bottom of the page on user scroll using Vanilla JS. I googled it out and found that below check works fine for most of the scenarios -
window.innerHeight + window.scrollY) >= document.body.offsetHeight
It works fine yes when in my react application I have not set height as 100vh in my App.css and index.css. But after setting the height as 100vh in both of them it does not.
I was consoling the values of above params without height as 100vh and below was the output on Galaxy S5 device -
window.innerHeight-> 640 window.scrollY -> 0 document.body.offsetHeight-> 265
Consoling the values of above params with height as 100vh and below was the output on Galaxy S5 device -
window.innerHeight-> 640 window.scrollY -> 0 document.body.offsetHeight-> 640
Below is handleScroll code:
handleScroll = () => {
const {
totalUsersCount, users, currentPage, fetchUsersList,
} = this.props;
console.log('window.innerHeight-> ', window.innerHeight, 'window.scrollY ->', window.scrollY,
'document.body.offsetHeight-> ', document.body.offsetHeight);
if (((window.innerHeight + window.scrollY) >= document.body.offsetHeight)) {
fetchUsersList(currentPage + 1);
}
};
How can I check for the bottom of page scroll, when the height is set as 100vh in Vanilla JS as I doing it in React.
When you set body height to 100vh, scrollHeight will remain the height of your window, whatever total content length actually is. scrollHeight doesn't actually return the height of your whole content (as you'd expect), but the visible space in which it can scroll.
What you want is not height css property value but max-height.
Try changing your css to
body {
/* height: 100vh; */
max-height: 100vh;
overflow: auto;
}
Also I don't think it is good to rely on window height for this, since you might later want to wrap your scrollable area (by adding a header for example), thus you'll loss some extra weight and might get errors in your calculation. If you have a reference (wether in React or with vanilla DOM parsing) to the element that handle the scroll (the one that contains your scrollbar), you can use the following test in your scroll function :
handleScroll = () => {
//...
if (target.scrollTop >= (target.scrollHeight - target.offsetHeight)) {
//... your stuff
}
}
Since for now body is your target, you can just :
handleScroll = () => {
//...
if (document.body.scrollTop >= (document.body.scrollHeight - document.body.offsetHeight)) {
//... your stuff
}
}
You need to use document.body.scrollHeight to get the actual height.
Reference : https://javascript.info/size-and-scroll-window#width-height-of-the-document
UPDATED:
for a specific element use any of the selectors and get its scroll height.
const el = document.getElementById('#id');
const scrollHeight = el.scrollHeight;
I'm a JavaScript novice. Have patience with me.
I searched this site for relevant questions and found two: How to get width of a dynamically created element with $comiple in Angularj and jQuery + CSS. How do I compute height and width of innerHTML?. Their relevance and their answers are discussed below. If I missed a relevant question and this is a duplicate question, please direct me to it.
I dynamically create a <div class="popup"> (call it "popup"), populate it with innerHTML from a display: none; <div> in the markup, and insert it on the page. The relevant CSS is:
.popup {
top: 0;
left: 0;
width: 200px;
height: 250px;
}
Using event.clientX, I position popup relative to the cursor position at the time the mouseover event fired, as follows:
var widthOffset = 75, heightOffset = 0;
var windowWidth, popupWidth;
// other code ...
windowWidth = $(window).width();
popupWidth = 200; // popup.style.width returns nothing (not null,
// not undefined, just nothing).
// when event.clientX is in the left half of the window, display popup
// offset to the right of clientX;
// when clientX is in the right half, display popup offset to the left.
if( event.clientX > windowWidth/2 ){ widthOffset = -(widthOffset + popupWidth);}
popup.style.top = event.clientY - heightOffset + "px";
popup.style.left = event.clientX + widthOffset + "px";
There is a working reduced case at the Pen Popup Project Reduced Case on CodePen.
The problem is that I want to programmatically obtain popupWidth not set it as a fixed quantity. But, as the comment states,
popupWidth = popup.style.width;
is nothing. (Maybe it's a null string: popupWidth === "". I'm uncertain.)
The answer to the first question referenced above said to insert popup into the DOM before trying to obtain its width. I have done this. (See the Pen.) Still, it doesn't work.
A comment to the second answer to the second question said:
the root issues is that height cannot be set on an element with display:none.
I had display: none but when I changed it to display: block, and set popupWidth = popup.style.width;, popup "stuttered" fiercely on mouseover.
So the question remains: How do I programmatically get popupWidth just as I did with windowWidth?
With help from #Redu and #torazaburo, the answer became clear.
popupWidth = popup.offsetWidth; is the correct statement but both these conditions must be true:
popup must have been inserted into the DOM, and
display: block; must have been set.
If popup is still in memory or display: block; has not been set, then popup.offsetWidth === 0. If both of the conditions are true, then popup.offsetWidth is equal to the width set in the CSS.
Thanks to both commenters for their help.
You can do like
var popupDiv = document.getElementsByClassName("popup")[0],
width = window.getComputedStyle(popupDiv).width;
If you deal with a window or document type of element then getElementsByClassName(element,null), element.offsetWidth or element.clientWidth doesn't work. You have to access the width value like
var w = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
