Using Video on HBS Websites

There are two ways to watch video on HBS websites: in a player embedded in the page, and in a lightbox, or modal window, that hovers above the page.

Modal: (click video thumbnail)

On recently redesigned websites both players have a minimum width of 564 pixels. On all other websites, the embedded video player is 480 x 270 px and the player in the modal window is 640 x 360 px.

All video files for external websites should adhere to the file size requirements at the top of the page. Videos will be automatically re-sized to fit the player.

For more on web design specifications please see our web style guide.

Video thumbnails
A video thumbnail is the image displayed in the video player when the video is not playing. YouTube automatically selects a thumbnail image for each video. If you would like to customize your video thumbnail, please indicate this in your YouTube request form and provide Marketing & Communications with an image.
