IAB-recommended banner sizes and file requirements to maximize compatibility across publisher inventory.

Kindly note!

We recommend always using IAB standard sizes when preparing your creatives. Non-standard dimensions significantly reduce the number of ad placements that can serve your ad, which may lead to limited delivery and lower performance.
