Importance of banner width and height

[Richard Smith]

Could you briefly introduce these four types (Simple or Geo cities or Cursor or Floating)? In addition, I do have the width and height of the banner but I can't link the banner and the zone

Banner Size is 300x250

Zone size is 320x250

    Banner and Zone size should get matched. Here Banner size and Zone size get Mismatched. In this case need to change the zone size same as banner size.
