When you’re planning to run a programmatic display campaign, it’s important to know what are the most popular and effective banner sizes. This is a critical component in running a programmatic campaign, and will determine the campaign reach, and what inventory you can access. Display-banner dimensions are controlled by publishers, and the inventory or ad-slots they make available on their site.
