As we’ve seen earlier in this chapter, impressive presentation aids do not take the place of a well-prepared speech. Although your presentation aids should be able to stand on their own in delivering information, do not count on them to do so. Work toward that goal, but also plan on explaining your presentation aids so that your audience will know why you’re using them.
One mistake you should avoid is putting too much information on an aid. You have to narrow the topic of your speech, and likewise, you must narrow the content of your presentation aids to match your speech. Your presentation aids should not represent every idea in your speech. Whatever presentation aids you choose to use, they should fulfill one or more of the functions described at the beginning of this chapter: to clarify or emphasize a point, to enhance retention and recall of your message, to add variety and interest to your speech, and to enhance your credibility as a speaker.
As a practical matter in terms of producing presentation aids, you may not be aware that many college campuses have a copy service or multimedia lab available to students for making copies, enlargements, slides, and other presentation aids. Find out from your instructor or a librarian what the resources on your campus are. In the rest of this section, we will offer some tips for designing good-quality presentation aids.
Easily Seen or Heard by Your Audience
The first rule of presentation aids is that they must be accessible for every audience member. If those in the back of the room cannot see, hear, or otherwise experience a presentation aid, then it is counterproductive to use it. Graphic elements in your presentation aids must be large enough to read. Audio must be loud enough to hear. If you are passing out samples of a food item for audience members to taste, you must bring enough for everyone.
Do not attempt to show your audience a picture by holding up a book open to the page with the photograph. Nobody will be able to see it. It will be too small for your listeners in the back of the room, and the light will glare off of the glossy paper usually used in books with color pictures so that the listeners in front won’t be able to see it either.
Text-based visuals, charts, and graphs need to be executed with strong, clean lines and blocks of color. Weak lines in a graph or illustration do not get stronger with magnification. You must either strengthen those lines by hand or choose another graphic element that has stronger lines. On a poster or a slide, a graphic element should take up about a third of the area. This leaves room for a small amount of text, rendered in a large, simple font. The textual elements should be located closest to the part of your graphi
