The Element.clientHeight read-only property is zero for elements with no CSS or inline layout boxes; otherwise, it's the inner height of an element in pixels. It includes padding but excludes borders, margins, and horizontal scrollbars (if present).

clientHeight can be calculated as: CSS height + CSS padding - height of horizontal scrollbar (if present).

When clientHeight is used on the root element (the <html> element), (or on <body> if the document is in quirks mode), the viewport's height (excluding any scrollbar) is returned. This is a special case of clientHeight.

Note: This property will round the value to an integer. If you need a fractional value, use element.getBoundingClientRect().


var intElemClientHeight = element.clientHeight;

intElemClientHeight is an integer corresponding to the clientHeight of element in pixels. The clientHeight property is read–only.
