Use size to your advantage. One of the most important decisions to consider when designing a sign board is the size of the design itself, as well as the size of the typeface and graphics[graphics?:graphics pattern] that you will be using. By simply applying a contrast in size, like making one element of your design vastly larger or smaller than another element, it can manipulate your message. For example, if you were to create a bold, over-sized headline at the top of your sign board, using a reduced type size for the tagline at the bottom, this makes the headline feel larger, therefore, giving it more of an impact.
