:: Standard Banner Ad Sizes ::.

The Internet Advertising Bureau (IAB) specifies standard size advertising banner sizes. The size 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 often set file size limitations on specific banner ads too as any image, especially multi-frame animated images add to the overall file size of the web page and thus increase the download time.

The IAB refers to banner ads as Interactive Marketing Units (IMU) Ad Formats and regularly approves new sizes and types (rectangle, pop ups, sky scrapers, etc.)  Here are a few of the traditional sizes:
