HTML <video> height Attribute

❮ HTML <video> tag

Example

A video player with a specified height and width:

<video width="320" height="240" controls> <source src="movie.mp4" type="video/mp4"> <source src="movie.ogg" type="video/ogg"> Your browser does not support the video tag. </video> Try it Yourself »

Definition and Usage

The height attribute specifies the height of a video player, in pixels.

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

Note: Do not rescale video with the height and width attributes! Downsizing a large video with these attributes forces a user to download the original video (even if it looks small on the page). The correct way to rescale a video is with a program, before using it on a web page.
