Starting in August 2002, the Ad Sizes Task Force began a process to reduce the number of ad sizes for the purposes of reducing the costs and inefficiencies associated with the planning, buying and creating online media. The result was the Universal Ad Package, a set of four ad sizes that all compliant member publishers have agreed to support. For a list of publishers that are currently compliant with the UAP standards, see below.

Universal Ad Package Compliance

Publishers who are UAP compliant provide advertisers a set of 4 ad units (728x90, 300x250, 160x600 and 180x150) that enable advertisers the ability to reach the majority of that publisher’s audience – using, collectively, these units.

Publishers who currently UAP compliant are listed below. They have been awarded the UAP Compliance Seal.
