What's the Difference Between jQuery's `width`, `innerWidth`, and `outerWidth`?

Distinguishing Width, InnerWidth, and OuterWidth in jQuery

To elucidate the differences between these properties, let's delve into their definitions and practical implementation.

Width

• Represents the element's width, excluding padding but including borders.
  innerWidth
• Defines the element's width, excluding padding and borders.
  outerWidth
• Encompasses the element's width, inclusive of both padding and borders.

Similarly, height, innerHeight, and outerHeight operate on the vertical dimension.

In your given example:

var div = $('.test');

The element has a defined width of 200px, height of 150px, and no padding or borders. Therefore, all three width-related properties (width, innerWidth, and outerWidth) return "200px". Likewise, all three height-related properties return "150px".

However, if padding or borders were applied to the element, the results would vary:

<div class="test">

In this scenario:

• width would still be "200px".
• innerWidth would be "180px" (200px - 20px padding).
• outerWidth would be "220px" (200px 2 × 5px border).

These properties provide a granular level of control for working with element dimensions in jQuery and accommodating various CSS styles.
