When you’re planning to run a programmatic display campaign, it’s important to know which banner sizes are most popular and effective. 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 by the inventory or ad slots they make available on their sites.
