Standard Web Banner Sizes

Web banner ads have a come a long since the dawn of the Internet Age. They are advertisements that appear in various sites on the internet. Internet advertising has gained popularity over land-based advertising. Experts normally provide customers an idea of the market, help them to choose the

banner designs carefully, and come-up with the most appropriate copy. The banners are placed on different parts of the webpage (at the bottom, sides, on top) for efficiency.



The IAB (Internet Advertising Bureau) launched its Reimagining Interactive Advertising initiative in early 2009. The objective was to discuss about standard advertising banner sizes with media agencies, creative agencies, and publishers in the new age of digital marketing.

The organization also created IAB Ad Unit Guidelines for in-page display ads, such as flat JPGs, animated GIFs, and standard Flash files. The procedures are applicable to media companies, marketers, and agencies that buy, sell, create, and plan interactive marketing/advertising. IAB Rich Media Guidelines are available for Rich Media ad formats like "transitional" and "peelback" web banner designs.



The goal is to simplify and reduce the work by following the framework of guidelines for web page design and advertising inventory. This is because many websites set file size limitations and only accept specific ad sizes. They charge more for larger ads (especially multi-frame animated images) that intensify the overall file size of the web page and increase the download time. Further, many sites have automated software to block standard web banner designs.

Everybody is free to define their own formats though standards and guidelines have evolved over the years. However, it would be wise to follow the standard banner size guidelines if you want get recognized as a great company, look professional, and become one of the top visited websites. Your traffic will increase on the site if your banner gets picked up and placed on another site (strong back links).

The web banner designs come in different sizes (button ad to leaderboard ad). Their size is measured in pixels.
