Below are some of the standard banner sizes used on web pages. It is a sort of convention to develop banners based on these sizes; however, we are not bound by these dimensions, as it were. Two other sizes for banners are also in use: 350x300 and 720x300. These are generally not used on web pages but as pop-up or pop-under ads displayed on separate browser windows.
The standard sizes for banners have been formulated by the Internet Advertising Bureau.

We list the most popular formats. You may identify other formats surfing the web. Have a look at your favorite websites to get some impressions what banner size they are using.
