35-mm Slide Presentation Tips

Slide projector must be ordered via Speaker AV Order Form.

  • You may view your slides using the Slide Viewers in the Speaker Ready Room.
  • Keep your slides with you when you travel, not in your luggage.
  • Use 2" x 2" paper or plastic mounted slides, designated for a 35mm Slide Projector. Be sure that they are clean and in good physical condition.
  • Critically examine every slide and try out the entire set under adverse light conditions before using them at the meeting.
  • Do not mix glass and paper slides. This mix means you must refocus each slide. Create slides from quality, sharp, camera-ready images. Newspaper and fax reproductions make poor slides!
  • Slides must be well designed, simple, and readable by everyone in the audience. It is worthwhile to use professional preparation services, if possible.
  • As a general rule, use one slide for each 1 or 2 minutes of presentation. Each slide should remain on the screen at least 20 seconds.
  • Devote each slide to a single fact, idea, or finding. Illustrate major points or trends, not detailed data.
  • Do not show long or complicated formulas or equations.
  • Use the absolute minimum number of words in the title, subtitles, and captions. Remember that standard abbreviations are acceptable.
  • Use bold characters. Do not use fancy serif fonts. A rule of thumb for the minimum height of readable lettering (size) is 3 millimeters on finished slides. Do not make slides from illustrations or tables that were prepared for publication, they are not good enough quality. A good way to test your material is to stand 1 foot away for every inch of original copy width. If you can't read it from that distance, then your audience will not be able to read it either when it is projected onto the screen.
  • Do not use more than 3 or 4 vertical columns and 6 to 8 horizontal lines on a slide or the information will not be readable. Whenever possible, present data using bar charts or graphs instead of tables. Color graphs are very effective whenever possible, and remember that contrasting colors are easier to see.
  • As a general rule, don't use more than 1 or 2 curves on one diagram; a maximum of 3 to 4 curves may be shown, but only if well separated. Label each curve; do not use symbols and a legend.
  • Mark each slide with a "thumb spot" or a "dot" on the lower left corner of the frame when the slide is held in the correct reading position. Rotate the slide 180° so that, that spot/dot is in the upper right hand corner. Number the slides in proper sequence so that you can read the number when the slide is in the tray ready for projection. Number slides consecutively, each number appearing ONCE in slide set.
  • Make duplicates if you need to show the same slide more than once during your talk, and give each its own number.
  • You may check out slide trays/carousels from the SRR (80-slot only). Please return to the SRR when done with your presentation and take your slides out. Don't leave trays behind anywhere.
  • Take the labeled slide tray to the student volunteer in your session room 30 minutes before your presentation (Student volunteers will not load slides. This is the speaker's responsibility.)
  • Don't forget to retrieve your slides immediately after your presentation. If materials are left behind and found, please check in with the Speaker Ready Room - 309/310 or the Annual Meeting Office, Room 401 to see if your slides have been found.
