Banner ad specs

Banner ads are static 320×50 display units. On Web, the same size can sit on a Moment, under the seek bar. For GAM setup, see GAM banner format.

Creative guidelines

Static only: No animation, video, or moving GIF elements.
Legibility: Use clear visuals and simple copy readable at 320×50. Avoid dense text, fine print, or cluttered layouts.
Contrast: Strong contrast between background, text, and logo.
Single focus: One brand mark and one short message work best at this size.
File size: Optimize the image so it stays within the maximum file size in the specifications table while remaining sharp.
