HTML DOM offsetHeight
Property
Example
Get the height of a div element, including padding and border:
Definition and Usage
The offsetHeight
property is a read-only property that returns the height of the element in pixels, including padding and border, but not margin. It returns an integer value in pixels.
Typically, an element's offsetHeight
is a measurement of the element's CSS height, including the element's border, padding, and the vertical scrollbar (if present and rendered), but not including the heights of pseudo-elements like :before
or :after
.
For the document's body object, it includes the linear sum of the CSS height of the replaced elements. The height of the content that extends downward for floating elements is ignored.
If the element is hidden (for example, the element or one of its ancestors has style.display
set to none
), it returns 0.
Note: To understand this property, refer to the CSS Box Model.
Tip: This property is often used together with the offsetWidth property.
Tip: Use the clientHeight and clientWidth properties to return the visible height and width of an element, including padding.
Tip: To add scrollbars to an element, use the overflow property.
This is a read-only property.

More Examples
Example
The following example demonstrates the difference between clientHeight/clientWidth
and offsetHeight/offsetWidth
properties:
var elmnt = document.getElementById("myDIV");
var txt = "";
txt += "Height including padding: " + elmnt.clientHeight + "px<br>";
txt += "Height including padding and border: " + elmnt.offsetHeight + "px<br>";
txt += "Width including padding: " + elmnt.clientWidth + "px<br>";
txt += "Width including padding and border: " + elmnt.offsetWidth + "px";
Example
The following example demonstrates the difference between clientHeight/clientWidth
and offsetHeight/offsetWidth
properties after adding scrollbars to the element:
var elmnt = document.getElementById("myDIV");
var txt = "";
txt += "<b>div style information:</b><br>";
txt += "Height including padding: " + elmnt.clientHeight + "px<br>";
txt += "Height including padding, border, and scrollbar: " + elmnt.offsetHeight + "px<br>";
txt += "Width including padding: " + elmnt.clientWidth + "px<br>";
txt += "Width including padding, border, and scrollbar: " + elmnt.offsetWidth + "px";
