Interactive Advertising Bureau (IAB) Issues Guideline for Half-Page Ad Units

New York, NY (April 6, 2004) – Keeping pace with the development of new effective online ad units, the Interactive Advertising Bureau’s (IAB) Ad Sizes Task Force Today announced a standard specification for the half page ad unit. The standard will enable advertisers and their agencies to develop one iteration for half page ad content accepted by all of those publishers that accept the ad unit.

“After soliciting industry feedback on the efficacy of the half page ad unit, and in recognition of its growing usage, the Task Force is recommending the 300 X 600 pixel unit, as the industry-wide specification for the half page unit,” said Adam Gelles, Director Industry Initiatives, IAB. “As with all of the IAB ad size recommendations, our goal is to simplify the process for advertisers and their agencies, and enable publishers to offer a consistent sized unit for their customers.”

The specifications for the half page unit and file sizes are as follows:
