jQuery provides a good number of methods, including height(), innerHeight(), outerHeight(), width(), innerWidth() and outerWidth() to set and get the CSS dimensions for the elements. Take a look at the illustration below to understand how these methods are calculating the dimensions of an element's box.
The width() and height() methods in jQuery are used to get or set the width and the height of the element respectively. The width and height that were set or gotten don't include padding, border, and margin on the element. The example below shows how you will return the width and height of a <div> element.

</html>Also, within the width() and height() method, you can set the width and height of the element by including the value as a parameter. This value may be a string (i.e. number and unit e.g. 100px, 20em, etc.) or a number. The example below shows how you will set the width of a <div> element to 400 pixels and height to 300 pixels respectively.

The innerWidth() and innerHeight() methods in jQuery are used to get or set the inner width and the inner height of the element respectively. This inner width and height include the padding, however, it excludes the border and margin on the element. The example below shows how you will return the inner width and height of a <div> element with the click of a button.

<p><strong>Note:</strong> jQuery <b>innerWidth()</b> includes the CSS properties (<b>width</b> + <b>padding-left</b> + <b>padding-right</b>), whereas the <b>innerHeight()</b> includes (<b>height</b> + <b>padding-top</b> + <b>padding-bottom</b>).</p>
</body>
</html>
also, the innerWidth() and innerHeight() methods can be used to set the element's inner width and height by passing the value as a parameter. The innerWidth() and innerHeight() methods only alter the width or height of the element's content area to match the specified value.
Take for instance, if the current width of the element is 300 pixels and the sum of the left and right padding is 50 pixels then the new width of the element after setting the inner width to 400 pixels is 350 pixels; i.e New Width = Inner Width - Horizontal Padding. Also, you can estimate the change in height while setting the inner height.

The jQuery outerWidth() and outerHeight() methods in jQuery are used to get or set the ‘outer width’ and the ‘outer height’ of the element respectively. The outer width and height consist of padding and border but exclude the margin on the element. The example below shows how you will return the outer width and height of a <div> element with the click of a button.

We can also get the outer width and height that includes padding and border as well as the margin of the element. To do that just specify the true parameter for the outer width methods, like this outerWidth(true) and outerHeight(true).

</html>More so, you can also set the element's outer width and height by passing the value as a parameter to the outerWidth() and outerHeight() methods. Most importantly, these methods only alter the width or height of the element's content area to match the specified value, like the innerWidth() and innerHeight() methods.
Take a look at this example, if the current width of the element is 300 pixels, the sum of the left and right padding is 50 pixels, and the sum of the width of the left and the right border is 20 pixels then the new width of the element after setting the outer width to 400 pixels is 330 pixels i.e New Width = Outer Width - (Horizontal Padding + Horizontal Border). also, you can calculate the change in height while setting the outer height.
