Presentation Guidelines

Oral Presentations

Speakers must be in the meeting room 45 minutes before their session begins to load their presentation and check in with the session chair. Presentations should be labeled with their presentation number and last name, e.g 14Smith. A MAC will be provided by the meeting in each room. Keynote and Powerpoint will be available. The slides should be created in a 16:9 format. Bring your presentation on a usb stick to load on the conference computer. 

All plenary and parallel session presentations are 12 minutes: 10 minutes for the talk and 2 minutes for a question and answer period. *There are shorter presentations for community updates. The speakers for those talks will be notified. 

Because oral presentation requests far exceed the number of slots available, all authors should be prepared to present a poster if their abstract is not selected for an oral presentation.

Standard equipment provided in each plenary, workshop, and platform session room includes an LCD data projector, screen, lectern, pointer, and microphone.

Please note: for those presenting in Royce Hall, the front doors will be locked until 45 minutes before the session starts. All presenters in Royce Hall should enter on the door to left, next to the lobby, labeled, "Presenter Entrance".


Preparing Effective Oral Presentations



  1. Presentations should be in 16:9 format.
  2. Keep visuals clear and easy to read. Abbreviate your message. SIMPLE graphs, charts and diagrams are much more meaningful to an audience than complex cluttered ones.
  3. Avoid using too many patterns and graphics in one frame.
  4. Use a minimum of words for text and title frames. Five to eight lines per frame and five to seven words per line are the maximum-fewer is better.
  5. Use upper and lower case lettering, which is more legible than all capital letters.
  6. Vary the size of lettering to emphasize headings and subheadings, but avoid using more than three sizes per frame.
  7. Select sans serif type (example: Arial) which projects better and is easier to read than serif type.
  8. Maintain the same or similar type sized from frame to frame, even if some frames have less copy than others.
  9. Keep all type horizontal, even in charts.
  10. Consider color with care. A dark background with highly contrasting text and graphics is most readable. Cool colors (example: deep blue, turquoise, purple) appear to recede and make white or light colored text more readable. In one study, blue was found to be the most effective background color for projection. Do not use red for text; it is extremely difficult to read.
  11. Highlight your main point or heading with a dominant color (example: yellow for the heading, white for body text). Avoid the use of intensely bright or saturated colors that compete with the text.
  12. Maintain a consistent color scheme. Use no more than six colors throughout your presentation.
  13. Select backgrounds to enhance your text or graphics. A background that transitions smoothly from lighter to darker shades of the same hue can be effective. Some software packages permit the gradation from one color to another. A textured background can be effective, but it should not detract from or compete with text or images.
  14. Remember the basics of good design: Plan a template. Use colors consistently with light fonts on a dark background. Keep text clear and easy to read.
  15. After finalizing your presentation, you may consider going back and deleting two slides so as to keep your presentation on time.


Poster Presentations

All regular submitted abstracts will be scheduled as posters. If a regular submitted abstract is scheduled in a concurrent session, the author must still display and present a poster. The poster area will be open on a 24-hour basis beginning on March 12, 2019 at 5:00 p.m. through March 16, 2019 at 9:00 a.m. in the exhibit and poster area. Posters may be mounted on boards beginning at 5 p.m. on March 12, 2019. Two posters will share an 8’wide by 4’ tall space. Posters that are larger than 3’8” tall by 3’10” wide will be removed. Please note that the posters should be formatted in a vertical (portrait) layout. GSA cannot be responsible for items left in the hall including but not limited to poster tubes, purses, backpacks, etc. Please keep personal items with you at all times.

All posters will be located in the exhibit and poster area at the conference site. You must be wearing your official meeting badge to gain entry to the exhibits and posters.

IMPORTANT: Poster Size and Format

Each presenter is allotted one-half of a 4' x 8' (height x width) board. Posters should be formatted in PORTRAIT/VERTICAL format. Posters using more space than allotted will be removed. The GSA staff, facility staff, and personnel breaking down the boards will not be responsible for posters left up by their authors. Work crews will remove posters that remain on the poster boards after 10 p.m. on March 30, 2019.

The Poster presentation schedule will be available in May, 2019. GSA will place a number on your poster board. 

If you do not want photos taken of your poster, you should add this icon to your poster.

Preparing Effective Posters

Here are some tips for ensuring your poster presentation is effective:

  • PLAN: An effective poster requires careful thought and preparation. It is not sufficient to enlarge an abstract and add a few figures. First identify your one, two, or three principal messages. Then work out the most effective way to convey those points and choose a headline to help highlight each message. Your poster should be self-explanatory so that you are free to answer questions and expand on particular points.
  • TEXT: Your poster text should be easily readable and the design well organized. Use a type size that can be read easily at a distance. Text that is too small is the most common problem in poster design. Keep the text succinct.
  • GRAPHICS: Summarize current research with clear and self-explanatory graphics: charts, tables, micrographs, diagrams etc. Simple use of color can add emphasis.
  • TITLE: Prepare a heading at the top of your poster indicating the abstract title, authors, and affiliations. Make the title large enough to be read easily from a reasonable distance (~ 4 feet). Authors may opt to include a picture of themselves to allow people to find them to discuss their work after the day of their presentation.
  • METHODS: Details of methodology should be brief and placed at the end of the legend.
  • CONCLUSION: Many successful posters provide a bulleted list of conclusions and questions raised.
  • REFERENCES: Some references should be provided, but they need not be as extensive as those in papers.
