There are at least 18 ad sizes on the Google Display Network (potentially more depending on what country you’re in). Each of them a different size and shape. Generally, the space above the fold is considered the most lucrative ad space since it’s the first thing people see when they land a page. More info about Google Display Network can be found here but below are the most sizes.
