An ad template is the size of an ad theme that is measured in pixels. Each ad theme in our theme gallery is comprised of different ‘ad templates’ or ad sizes. The different ad templates include: 728X90, 160X600, 300X600, 300X250, 320X50, 300X50 (all measured in pixels).
For example: The 320X50 ad template is for mobile, and the 728X90 ad template is known as a ‘leaderboard banner’ and is typically placed at the top of a webpage.
