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)
Reference: https://help.optimizely.com/Build_Campaigns_and_Experiments/Use_screen_measurements_to_design_for_responsive_breakpoints
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 ... :)

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 have a fixed-positioned full-screen image gallery. The container div height is set via jQuery, and the next div (#page) has a margin-top equal to window.height.
Here is this code:
var windowH = $(window).height();
var windowW = $(window).width();
function marginTop() {
var currentH = $(window).height();
$("#page").css("margin-top", currentH +'px');
$("#image-gallery").css("height", currentH +'px');
console.log('mTop fired!');
};
$(window).resize(function() {
var newH = $(window).height(); // Records new windows height after resize
var newW = $(window).width();
var maxH = windowH + 90; // Sets a positive delta of some px
var maxW = windowW + 60;
var minH = windowH - 90; // Sets a negative delta of some px
var minW = windowW - 60;
if(newH > maxH) { // If the height difference is more than 50px, then set new marginTop for #page
marginTop();
console.log('fire for bigger height');
} else if(newH < minH) {
marginTop();
console.log('fire for smaller height');
} else if(newW > maxW) {
marginTop();
console.log('fire for bigger width');
} else if(newW < minW ) {
marginTop();
console.log('fire for smaller width');
}
});
I've split the conditions in several else if statement because it didn't work fine, and I had to check out when it was working, when not.
The various if...elseif...elseif... solve a problem on mobile browsers: without that delta, the #image-gallery div would change dimension when the address bar appears or disappears, resulting in stuttering adjustments of the div's height. Moreover, i did not want to redraw the whole thing for small changes in viewport on desktop too.
However it has some problem, as it doesn't work correctly. In particular:
marginTop() is fired only for window.resize with smaller height (checked from console.log)
on desktop, if the window is resized through the top-right-corner button, it doesn't fire at all.
removing all the if-else-if conditions, it works fine on desktop in any situation (but the address-bar is still a problem on mobile)
Can't figure it out, the code seems fine to me, but not to browsers. Where's the catch?
Tested on Firefox and Chrome latest
There's a host of small problems here. Your if statement, as is, will never reach the width compares. First of all, with the width being in a if else with the height, then height is always evaluated first and width is never hit if height is adjusted.
Next, your "current height|width" as seen at var windowH = $(window).height(); is never reset. This means, if the user show up with a viewport (say browser is minimized) of 200:150, then height:width will always be measured based on 200:150. This would make for a very different experience from someone using a much larger viewport.
Another issue, often found with window re-sizing, is the multiple amount of times your code will fire. This can cause major issue with overlapping commands, thus causing double feedback.
Below is how I would handle this and a suggested rebuild.
/* simple method to get the current window size as an object where h=height && w=width */
function getWindowSize() {
return { h: $(window).height(), w: $(window).width() };
}
function doWork(typ, msg) {
// report msg of change to console
console.log(typ == 'h' ? 'HEIGHT:\t' : 'WIDTH:\t', msg);
// we really only need fire your method if height has changed
if (typ == 'h') marginTop();
// a change was made, now to reset
window.sizeCheck = getWindowSize();
}
// your original method
// brokered off so it can be used independently
function marginTop() {
var currentH = $(window).height();
console.log('currentH', currentH)
$("#page").css("margin-top", currentH +'px');
$("#image-gallery, #page").height(currentH);
console.log('mTop fired!');
}
/* action area for window resize event */
function windowResize() {
// made my variables short and sweet,
// sch=sizeCheck, scu=sizeCurrent
var sch = window.sizeCheck, // get previously set size
scu = getWindowSize(),
maxH = sch.h + 90,
minH = sch.h - 90,
maxW = sch.w + 60,
minW = sch.w - 60;
if (scu.h > maxH) doWork('h', 'View Got <b>Taller</b>');
else if (scu.h < minH) doWork('h', 'View Got <i>shorteR</i>');
// for what you want, the following isn't even really nec
// but i'll leave it in so you can see the work
if (scu.w > maxW) doWork('w', 'View Got <b>Wider</b>');
else if (scu.w < minW) doWork('w', 'View Got <i>thinneR</i>');
}
$(function() {
// ezier to maintain one global variable than to scope
// shot 2 which could easily be overriden in a latter method,
// by simple confusion
window.sizeCheck = getWindowSize();
// call of event to establish correct margin for the page div
marginTop()
$(window).resize(function(e) {
// this will clear our timer everytime resize is called
if (this.tmrResize) clearTimeout(this.tmrResize);
// resize is called multiple times per second,
// this helps to seperate the call,
// and ensure a little time gap (1/4 second here)
this.tmrResize = setTimeout(windowResize, 250);
});
})

Someone passed by and then voted -1 to my question. I'd just like to know who's the braveheart that judges others without even posting a simple comment. This behaviour should be forbidden, we're not on 9gag neither 4chan.
I am using an image as the background for my site. It has a black/white gradient, and is 1px wide.
The CSS:
background-image:url('../image/gradient.png');
which makes it repeat itself. The height of the image is 2000px.
Is it possible to change the height of the image dynamically, so it fits all page sizes: If the height of a page is less than 2000px, the height of the image should be smaller, if the height of the page is bigger, the image should be bigger.
Thanks in advance
I have tried various in-browser gradient techniques, and they dont seem to work the same on all browsers.
I usually approach this problem in one of two ways.
If you can use CSS3, then use CSS gradients (I always find http://colorzilla.com/gradient-editor/ a good choice to play about with gradients), you can then set this to be 100% height of the window.
If CSS3 isn't an option, i usually just pick a height, say 500px, and make a gradient for that. Then, since gradients typically go from colour A to colour B, just set the underlying background colour to match colour B and the gradient will work similarly on all monitors.
Assuming a gradient going from blue to black:
body {
/* ensure body always fills viewport */
min-height: 100%;
/*gradient fades to black so set underlying BG to black*/
background: url(/path/to/gradient.gif) repeat-x #000;
}
}
Maybe am not getting the right context of your question, but this can be do it easily with somethin like
#SomeImg.src {
width: 100%;
position: absolute;
top: 0;
left: 0;
}
Resize this page to see it action: http://css-tricks.com/examples/ImageToBackgroundImage/
With CSS3 you can use background-size: cover and there are some other techniques discussed here.
You could create several images with varying heights and dynamically match the closest image size. If you do this you'd need to tie into the window.resize event to update the image if the user resizes the window.
window.onload = setBackgroundImage;
window.onresize = setBackgroundImage;
function setBackgroundImage() {
var winH = 500;
if (document.body && document.body.offsetWidth) {
winH = document.body.offsetHeight;
} else if (document.compatMode=='CSS1Compat' && document.documentElement && document.documentElement.offsetWidth ) {
winH = document.documentElement.offsetHeight;
} else if (window.innerWidth && window.innerHeight) {
winH = window.innerHeight;
}
if (winH > 400) {
document.body.style.backgroundImage = "url('../image/gradient800px.png')";
} else if (winH > 800) {
document.body.style.backgroundImage = "url('../image/gradient1000px.png')";
} else if (winH > 1000) {
document.body.style.backgroundImage = "url('../image/gradient1500px.png')";
} else if (winH > 1500) {
document.body.style.backgroundImage = "url('../image/gradient2000px.png')";
} else {
document.body.style.backgroundImage = "url('../image/gradient400px.png')";
}
}
I don't think the solution is very pretty, but it should work.
