Most Effective Utilization of Overhead Cells

Effective Use of Overheads

  1. Limit each visual to one idea. If the topic is complex, consider using overlays to build a concept or present a complicated issue.

  2. Keep visuals simple. Remember the six-by-six rule: No more than six lines per transparency, no more than six words on a line. Use active words and short phrases.

  3. Use 18 point type (quarter-inch high letters) or larger. Type should be non-ornamental, easy to read, and kept within a centered 8 by 10 inch box to allow for framing on the projector stand.

  4. Don't use more than two type styles on any single visual. Use the same typeface for a series. Mix upper-case letters for readability, with occasional use of all caps for contrast or headings.

  5. Use tinted film to reduce lamp glare; add colored markings for realism and emphasis. Tints can be used for a series on one topic, but use only two or three colors per transparency. Too many colors make it difficult for the eye to focus on important parts of the overhead.

  6. Don't mix horizontal and vertical formats or use vertical lettering. Many experts suggest using horizontal formats (just as in 35mm slides) exclusively for maximum visibility.

  7. Position material on the upper part of your transparency. Your audience can see the top of the screen better than the bottom.

  8. Don't number items unless the rank order is germane. Use check marks, bullets, boxes and arrows.

  9. Turn the projector lamp off during discussions to focus the participants' interest and attention. Keep blank sheets of film nearby for ad libbing and don't be afraid to add marginal comments to your transparencies during the presentation.

  10. Before giving the presentation, view your overheads from all angles, especially the sides and back of the room, to ensure they'll be clearly read and understood by everyone.
