Ease of Reading
Type should be easy to make out and comprehend:
· Fine or thin lines may disappear when projected. Text needs to be heavy(bold) enough to provide good contrast to the background.
· Avoid fonts that are too bold. The type may run together, making it difficult to read.
· Use no more than 2–3 typefaces and styles (bold, italic, etc.) per presentation.
· Change type sizes or vary type color to distinguish differences.
· Use large text sizes. Text should be large enough to read without effort. For most presentation media, titles should be 36- to 48-point and text should be 24- to 36-point for computer screen shows and 35-mm slides. For video, text should be a minimum of 30-point. For
posters, text should be a minimum of 24-point for the body, and 72-point for
the title.
· Different fonts may have the same point size but can vary in line length(Fig. 7).
