Preparing Your Poster for DDW

Photography Policy

The photography policy allows photos of posters for personal, social or non-commercial use; however, presenters have the right to request no photography, and in those situations, photography is strictly prohibited. If you do not want to allow attendees to take photos of your poster, you may hang a DDW “no photos” icon sign, available at the Poster Hall Information Desk, on your poster board on your assigned day.

Poster Number

Each poster board is assigned a number corresponding to the poster numbers listed in the in the program. For example, Sa1000 is poster 1000 presented on Saturday. Please use the board that corresponds with your abstract number.

Poster Size

The maximum size of DDW poster presentations is 4’ high by 6’ wide. DDW will provide tacks to affix your presentation to the poster board along with a poster presenter ribbon at each poster board.

Required Information

Poster presentations must include full disclosure information for the entire author string. Product-specific promotional material or event listings are prohibited on posters or in the Poster Hall.

Suggested Guidelines for Preparing an Effective Poster

We will provide suggested templates that you may use for your poster or you can use your own format as long as it does not exceed the 4’ high by 6’ wide size limitation. DDW suggests the following templates:

  • Text Lettering: Lettering for text and illustrations should be at least a font size of 30 points (0.4” or 10.5mm).
  • Depicting Sections: Each section should be numbered with text in a font size of 50 points (0.7” or 17.5mm) to guide the reader through your poster. Color is an effective method for separating sections and adding graphic impact. Try to avoid color combinations that are difficult to read.
  • Premise: Your poster should include three to five brief sentences that outline the information necessary to understand the study and why it was performed. The question(s) to be asked or the hypotheses tested should be clearly and succinctly stated.
  • Methods: Outline your methods briefly, providing only details for new methods, or modifications of older methods.
  • Graphics: Results presented in the form of a graph or chart are always more effective than blocks of text. Provide a legend for symbols and other details and interpretation of results below each panel.
  • Conclusion: State the conclusion succinctly in large type. Many viewers read this first; hence, it should be easily understandable.

Poster Presenter Training Sessions

In the morning before the Poster Hall opens, you will have the opportunity to learn techniques for effective poster presentations from experienced presenters. Training sessions will take place in the DDW Knowledge Hub, located in the Poster Hall (South Hall A) on Saturday, May 2 through Monday, May 4 from 7:30 to 7:45 a.m.

Poster Printing Service

DDW is offering a poster printing service (fee required) for accepted poster presenters at DDW 2020 that includes printing, packaging, and shipping directly to McCormick Place. Presenters can access the poster printing submission site using the login credentials sent by email from in mid-March to view suggested templates and shipping information.


To increase the visibility and reach of your science, you are encouraged to submit an ePoster. DDW attendees and the public will be able to view this electronic version of your poster along with any audio narration or video files you choose to add. This service is provided free of charge and expands the reach of your science to your colleagues. Visit the DDW ePosters Archive to view examples from previous meetings.

The secure ePoster submission and poster printing site will be open in mid-March. Presenting authors should refer to the email message that will be sent from in mid-March for login information. Full submission instructions and ePoster FAQs are available on this site.
