Banners are a common feature and the standard accepted size is 460 x 60 pixels. Banners of course, can be of any size and are usually posted horizontally. Banners are created to be noticed but keeping banners simple is also recommended. Banners that are “noisy” with distracting animations can have a negative effect. Smaller banners can be used as avatars in the many chat programs that we use. Banners can be used to post important messages on bulletin boards and other web modules. Gif banners are the simplest to create and easy to publish on websites. Banners can also be made in Flash format which may suit the more commercial website. The samples you see below are the standard half size - but banners do come in all sorts of shapes and sizes.
