HTML <video> width Attribute

The width attribute on a <video> tag sets the width of the video player. The width is specified in pixels -- without the ‘px‘ unit.

Example

#

A width attribute on a <video> element.
The width attribute overrides the original video width.

<video width="320" height="240" controls>
  <source src="/media/movie.mp4" type="video/mp4">
  <source src="/media/movie.ogg" type="video/ogg">
</video>

Using width

The width attribute sets the width of the video element.

The width is defined in pixels, without the 'px' unit.

The browser will maintain the correct aspect ratio if the height is not set.

Tip: Try using the actual dimensions of the video file.
It requires fewer resources to play a video in the actual size.
