AAPT Transparency Preparation Guidelines

These remarks are intended for preparation of transparencies. Please consider them as thoughtful suggestions designed to enhance your presentation and the enjoyment and understanding of your audience.

  • Consider the visual impact your presentation needs to make in order to interest the audience. Everything should be legible.

  • Choose a simple font such as Times, Helvetica or Prestige Elite and stick with it. Avoid overuse of outlining and shadowing, It can be distracting. To make something stand out, use a larger font size, bold or underline instead. Framing the text by putting a box around it will also help the audience focus.

  • The title should be in very large type, 48 pt or larger. Headings and sub-headings should be at least 36 pt. You need not use all capitals for titles and headings, it can sometimes make them harder to read.

  • Text on sheets should be between 18 and 24 pt to be legible. Use double or 1.5 spacing between lines of text. Keep each sheet relatively short and to the point. Readability is best when there are no more than 10 – 12 lines of text on a transparency.

  • Whenever possible, use graphs, charts, tables, figures, pictures or lists instead of text to get your points across.

  • Make sure your presentation flows in a logical sequence. It should have an introduction, body and conclusion, just like any other presentation. Arrange it ahead of time to make sure it follows the correct order.
