You may have heard the term ‘IABs’ bandied about by ad professionals in the past and thought to yourself, what on earth are they talking about?
If you’ve tried googling IAB, you’ll have only been able to find information about the Internet Advertising Bureau (which is, technically, the source of this term) but clearly isn’t what ad professionals mean when they ask ‘where are my IABs?’
When we (ad people) use the term IABs we’re just referring to adverts that adhere to the starndardised set of size specifications that the actual IAB set out for everyone.
So, when you next hear ‘IABs’ you’ll know that it’s just industry jargon for regulation spec ads. Nothing too exciting!
The actual IAB specs (now, in 2022) are:
Ad Unit Name
Fixed Size (px)
Max kB: Initial Load
Max kB: Subload
300x50 or 320x50
Super Leaderboard/ Pushdown
Mobile Phone Interstitial
640x1136 or 750x1334 or 1080x1920
Feature Phone Small Banner
Feature Phone Medium Banner
Feature Phone Large Banner
