'Get div height with plain JavaScript

Any ideas on how to get a div's height without using jQuery?

I was searching Stack Overflow for this question and it seems like every answer is pointing to jQuery's .height().

I tried something like myDiv.style.height, but it returned nothing, even when my div had its width and height set in CSS.

Solution 1:[1]

var clientHeight = document.getElementById('myDiv').clientHeight;

or

var offsetHeight = document.getElementById('myDiv').offsetHeight;

clientHeight includes padding.

offsetHeight includes padding, scrollBar and borders.

Another option is to use the getBoundingClientRect function. Please note that getBoundingClientRect will return an empty rect if the element's display is 'none'.

Example:

var elem = document.getElementById("myDiv");
if(elem) {
  var rect = elem.getBoundingClientRect();
  console.log("height: " + rect.height);  
}

UPDATE: Here is the same code written in 2020:

const elem = document.querySelector("#myDiv");
if(elem) {
  const rect = elem.getBoundingClientRect();
  console.log(`height: ${rect.height}`);
}

jsFiddle

var element = document.getElementById('element');
alert(element.offsetHeight);

Solution 4:[4]

var myDiv = document.getElementById('myDiv'); //get #myDiv
alert(myDiv.clientHeight);

clientHeight and clientWidth are what you are looking for.

offsetHeight and offsetWidth also return the height and width but it includes the border and scrollbar. Depending on the situation, you can use one or the other.

Hope this helps.

The other answers weren't working for me. Here's what I found at w3schools, assuming the div has a height and/or width set.

All you need is height and width to exclude padding.

    var height = document.getElementById('myDiv').style.height;
    var width = document.getElementById('myDiv').style.width;

You downvoters: This answer has helped at least 5 people, judging by the upvotes I've received. If you don't like it, tell me why so I can fix it. That's my biggest pet peeve with downvotes; you rarely tell me why you downvote it.

In addition to el.clientHeight and el.offsetHeight, when you need the height of the content inside the element (regardless of the height set on the element itself) you can use el.scrollHeight. more info

This can be useful if you want to set the element height or max-height to the exact height of it's internal dynamic content. For example:

var el = document.getElementById('myDiv')

el.style.maxHeight = el.scrollHeight+'px'

try 

myDiv.offsetHeight 


console.log("Height:", myDiv.offsetHeight );
#myDiv { width: 100px; height: 666px; background: red}
<div id="myDiv"></div>

Best way is -

var myDiv = document.getElementById('myDiv');

var myDivWidth = myDiv.clientWidth || myDiv.offsetWidth || (myDiv.getBoundingClientRect()).width;
var myDivHeight= myDiv.clientHeight || myDiv.offsetHeight  || (myDiv.getBoundingClientRect()).height;
          
console.log("Width: "+ myDivWidth + "px");
console.log("Height: "+ myDivHeight + "px");
<div style="padding: 50px; margin: 8px auto; outline: 1px solid green;">

  <div id="myDiv" style="width: 100%; height: 256px; padding: 50px; margin: 4px; background: #000000; color: #ffffff; outline: 1px solid red;">
  This is "#myDiv" <br>
  Width: 100% <br>
  Height: 256px
  </div>

</div>

Here's one more alternative:

var classElements = document.getElementsByClassName("className");

function setClassHeight (classElements, desiredHeightValue) 
    {
        var arrayElements = Object.entries(classElements);
        for(var i = 0; i< arrayElements.length; i++) {
            arrayElements[i][1].style.height = desiredHeightValue;
        }

    }

One option would be

const styleElement = getComputedStyle(document.getElementById("myDiv"));
console.log(styleElement.height);

  1. HTMLElement.style - returns defined Style of element
  2. clientHeight - height + padding
  3. offsetHeight - height + padding + borders
  4. scrollHeight - return height + padding
  5. getBoundingClientRect() - return left, top, right, bottom, x, y, width, and height properties
  6. getComputedStyle() - returns all CSS properties of an element

// returns defined Style of element
const styleHeight = document.getElementById('myDiv').style.height;
console.log('style Height : ', styleHeight);

// height + padding
const clientHeight = document.getElementById('myDiv').clientHeight;
console.log('client Height : ', clientHeight);

// height + padding + borders
const offsetHeight = document.getElementById('myDiv').offsetHeight;
console.log('offset Height : ', offsetHeight);

// height + padding
const scrollHeight = document.getElementById('myDiv').scrollHeight;
console.log('scroll Height : ', scrollHeight);

// return left, top, right, bottom, x, y, width, and height properties
const getBoundingClientRectHeight = document.getElementById('myDiv').getBoundingClientRect().height;
console.log('get Bounding Client Rect Height : ', getBoundingClientRectHeight);

// returns all CSS properties of an element
const styleElementHeight = getComputedStyle(document.getElementById("myDiv")).height;
console.log('style Element Height : ', styleElementHeight);
<div id="myDiv" style="margin:10px;padding:20px;height:200px;">
    <input type="Text">
    <input type="button" value="submit">
</div>

<div id="item">show taille height</div>
<script>
    alert(document.getElementById('item').offsetHeight);
</script>
