Way finding signage is one of the most important tools in a civilized society being said, we as people hate to be missed guided or to get lost when trying to locate something and that’s when way finding signage comes in. Way finding in a more brief term is signage that helps people navigate from place to place as for a example, Street signs help us locate where were going how to get back from where we started and how to refer someone to a street, without way finding signage there would be a lot of lost people. Another example of signage is in the design of billboards, there is a rule of thumb named the 55mph rule. What this rule means is that a successful billboard must contain a high contrast, limited content and of course it must contain a legible font that will create a memorable impression within the viewer. In signage especially in street signs legibility is key this means that there should almost always be a sans-serif bold font used to ensure legibility. Sans-serif fonts are used everywhere within the U.S and they can be located within just about every street sign you see.
