(4) Determining letter size. The key to legibility is the size of
the lettering in the graphics project, not the overall size of the
project. Just because the overall size of a project is relatively
small, that alone does not dictate the use of small lettering in the
project. The distance from which the viewer must see and understand the
project does dictate the size of the lettering used in a graphics
project. The closer the viewer is to the project, the smaller the
lettering on the project; conversely, the farther away from the project
the viewer is, the larger the letter you must use.
Figure 176 shows the minimum letter height required for a given
distance. If the viewer is 10 feet from the project, the minimum size
letter on a graphic project would be .350.

PART C COMPUTER IMAGING SYSTEMS
Terms and Definitions.
Before you can use any system or piece of equipment, you must understand
