IAB Ad Unit Guidelines
The Interactive Advertising Bureau (IAB) is an organization that was set up to not only police the internet advertising world - but also to help promote internet advertising as a whole. The IAB does not make mandatory guidelines on any of the ad sizes, but it was determined that if everyone used approx. the same size ads - it would make life on the media planner and advertiser a whole lot easier. So below you will find the IAB recommended ad sizes that we try to follow:
Rectangles and Pop-Ups |
Banners and Buttons |
Skyscrapers |
Those sizes that are bold above are part of the Universal Ad Package.
