Exploring Standard Ad Unit Sizes: Google AdSense 300 x 250 – Medium Rectangle

CNN Web page has 300x250 Display Ad in the right sidebar

This is the first of a series of posts on Google AdSense ad sizes. The main reason I’m doing this is for my own reference. There won’t necessarily be any great insight or advice on how to use these ads. It is mainly a test environment so I can see all of the current AdSense options in action.

Four Recommended Ad Sizes

AdSense has four main recommended AdSense ad unit sizes, which are the following:

• 300 x 250 – Medium Rectangle
• 336 x 280 – Large Rectangle
• 728 x 90 – Leaderboard
• 160 x 600 – Wide Skyscraper

The 300×250 – Medium Rectangle

This ad can contain either text ads or banner ads. This ad unit can be seen throughout the Internet on web sites everywhere and is not only the main recommended size by Google AdSense, but also by the Yahoo! Advertising Network, Microsoft Advertising and the Interactive Advertising Bureau.

Usually, the 300×250 – Medium Rectangle is found either in a side bar or directly in the content with the text wrapped around it, as seen here.
