Poster Presentation Guide

Please read the poster section of ASLO’s guide on preparing a successful presentation.

Posters will be available in the poster gallery for the entire meeting. There will be dedicated poster sessions where you will be available to discuss and answer questions about your presentation. Outside of your session, you will be able to interact with attendees in two ways: text chat and video calls.

Poster presenters do NOT need to pre-record a talk about their presentation. Save your poster as a PDF.

Poster Content

The presentation must cover the material as cited in your abstract.

  • Place the title of your paper and your paper number prominently at the top of the poster board to allow viewers to identify your paper. Indicate 1) the abstract’s presentation number, 2) title, and 3) authors’ names.
  • Highlight the authors’ names, e-mails, and address information in case the viewer is interested in contacting you for more information.
  • Prepare all diagrams or charts neatly and legibly. Paragraph and figure caption text should be AT LEAST 24-point font (0.9 cm height) and headers AT LEAST 36-point font (1.2 cm height).
  • Use different colors and textures/symbols for each line or bar contained in your graph or chart. A serif font (e.g., Times) is often easier for reading main text, and a non-serif font (e.g., Arial or Helvetica) for headers and figure labels.
  • Organize the paper on the poster so it is clear, orderly, and self-explanatory. You have complete freedom in displaying your information in figures, tables, text, photographs, etc.
  • Use squares, rectangles, circles, etc., to group similar ideas. Avoid cluttering your poster with too much text. Label different elements as I, II, III; or 1, 2, 3; or A, B, C, making it easier for a viewer to follow your display.
  • Include the background of your research followed by results and conclusions. A successful poster presentation depends on how well you convey information to an interested audience.

Constructing Your Poster


  1. In PowerPoint, begin by creating a 1-slide PowerPoint presentation - choose a blank slide. (The entire poster must be contained in only one slide.)
  2. Adjust the slide size to make the poster dimensions a maximum of 48” x 36” (915 mm x 1220 mm) or a smaller size if desired.
  3. Save your poster as a .pptx file while you are working on it. (When you are all finished and ready to submit your poster, save a copy as .pdf)

Google Sheets

  1. Go to in your browser
  2. Click the big “+” symbol to start a new slideshow
  3. In “File / Page Setup” choose “Custom” and set the size of your slide to 48” x 36” (915 mm x 1220 mm) or to a smaller size if desired.
  4. In “Slide / Apply Layout” choose “Blank”
  5. When you are all finished and ready to submit your poster, choose “File / Download” and choose “PDF Document”

To keep the file size of your virtual poster manageable, use a tool like the Adobe's Acrobat On-line PDF Compressor to reduce your poster's file size.
