Here's the first page of a four page comic I drew in 2006. Generally in comics anything more than nine panels on a page looks cluttered. Watchmen, you may recall, is built around a nine-panel grid, and is dense with information. Dark Knight Returns uses a sixteen-panel grid, but back then Frank Miller was young and brilliant enough to pull that off. This comic was an attempt to use a rigid twenty-panel grid. As you will see, you can only fit so much in each panel.
