Description
The offsetWidth property returns the viewable width of an element (in pixels)
including padding, border and scrollbar, but not the margin.
The offsetWidth property is read-only.
Tutorial:
The offsetParent
All block-level elements report offsets relative to the offset parent:
- offsetTop
- offsetLeft
- offsetWidth
- offsetHeight
The offset parent is the nearest ancestor that has a position other than static.
If no offset parent exists, the offset is relative to the document body.

The Difference between
clientHeight/clientWidth and offsetHeight/offsetWidth
Without a scrollbar:
const elmnt = document.getElementById("myDIV");
let text = "";
text += "Height with padding: " + elmnt.clientHeight + "px<br>";
text += "Height with padding and border: " + elmnt.offsetHeight + "px<br>";
text += "Width with padding: " + elmnt.clientWidth + "px<br>";
text += "Width with padding and border: " + elmnt.offsetWidth + "px";
