Some of the considerations you should keep in mind when selecting typefaces for a map are the following: individual type of shapes or letterform, shape and flow of the text and the spatial organization of all the words typed on the page. It is common nowadays to use different typefaces to make something more attractive. However, when it comes to things like a map, typefaces can make a difference from great to worst. The individual type of shapes creates visual hierarchy in a map – an example of this one is Titus’ atlas of Hamilton Co., Ohio from Actual Surveys by R.H. Harrison C.E. and company.
The shape and flow of the text normally makes it easier for the buyer or reader of the map to know which location he or she wants to find; if you are representing a river, then you can make the shape and flow of the text appear like one. Lastly, spatial organization affects the entire design of the map – without this, a map would be difficult to understand.
