Definition and Usage

The naturalWidth property returns the original width of an image.

For example, if you have an image that is originally 100 pixels wide. Then, you style the image with CSS/or by using the HTML "width" attribute to make it 500 pixels wide. The naturalWidth property will return "100", the width property however, will return 500.

Tip: Use the naturalHeight property to return the original height of an image, or the height property to set or return the value of the height attribute of an image.

Note: This property is read-only.
