Ad size is the height and width of a display ad. There are more than a dozen ad sizes running on out-of-home signs and billboards - the most common and popular dimensions are measured in pixels and are 1800 w x 500 h and 1500 w x 500 h. For example, a large format 14’ h x 48’ w outdoor billboard bulletins typically requires 1800x500 pixel @96dpi in RGB and JPEG image. Larger ad sizes are recommended, because these ads are more viewable, perform better, more likely to be seen, and have higher recall rates.
