IAB banner specs
The following IAB banner specifications are for Workbench and Google Ad Manager.
Animated banners (animated GIFs) can loop only three times, and the total animation can’t exceed 15 seconds. Repetitive or rapid flashing, blinking in excess, or visually stressful animations aren’t allowed.
Assets may only be produced as JPEG, GIF, or PNG.
Up to 6x the pixel dimensions are supported for all IAB banners on Workbench. Specifications are optimized for all supported devices.
For campaigns sold directly by Apple, advertisers must provide assets that are at least 2x the pixel dimensions (for example, IAB 320 x 50 asset requirements would be 640 x 100).
For use of third-party ad tags, see Third-party ad tag technical specs. For ads utilizing any third-party ad tags, we recommend testing your ads with the Workbench Ad Tester.
