Banner Advertising Standard Sizes. The Internet Advertising Bureau (IAB) specifies standard advertising banner sizes. The size (dimensions) of your banner ad is important because the sites you want to advertise on may only accept certain size ads and typically charge more for larger ads. Webmasters also often set file size limitations on specific Banner Adverts too as any image, especially multi-frame animated images add to the overall file sizes of the web page and thus increases the download time of that page.
