Browser Support

Internet Explorer Firefox Opera Google Chrome Safari

The height attribute is supported in all major browsers.

Definition and Usage

The height attribute specifies the height of the <input> element.

Note: The height attribute is used only with <input type="image">.

Tip: Always specify both the height and width attributes for images. If height and width are set, the space required for the image is reserved when the page is loaded. However, without these attributes, the browser does not know the size of the image, and cannot reserve the appropriate space to it. The effect will be that the page layout will change during loading (while the images load).

Differences Between HTML 4.01 and HTML5

The height attribute is new for the <input> tag in HTML5.

<input height="pixels" />
