When it comes to media buyouts online, you need to have your creatives designed to certain specifications and dimensions. In an attempt to form some kind of universal ad standards, the IAB (Interactive Advertising Bureau) has created a set of standard sizes, some of which are used much more prominently than others.

Recommended File-types

  • Flat JPG/JPEG
