Poster Presentation Guidelines

Poster sessions afford an opportunity for presenters to engage attendees in a rich discussion of their research during a 1.5-hour session at CROI. Presenting authors illustrate their study findings by displaying graphs, figures, diagrams, and text that describes their main finding (options), background, methods, results, and conclusions on posters that also serve as reference materials after the conference.

New for CROI 2020: Template for an Alternate Poster Design

CROI is piloting a new poster format that is intended to attract interested attendees to your poster presentation by quickly focusing them on the main findings of the study. The format is optional, and we look forward to feedback from poster presenters and attendees.

Presenters may download the poster template in this PowerPoint slide. The slide notes contain a poster development guide that includes formatting notes (eg, font size, use of color, poster print size) and poster content requirements (eg, poster number and no QR codes).

Poster Videos

Poster presenters have the opportunity to upload an up to 5-minute video description of their research immediately prior to CROI. Poster presenter videos will be available to attendees during the conference via the CROI Mobile App, and available to the public after the conference on the CROI website.

Video Content: Poster presenter videos should (1) place the study in context with the field through a brief background, (2) briefly summarize the methods used in the study, (3) highlight important data and key results, and (4) focus primarily on important conclusions and the implications for future research.

Poster Video Upload Instructions

An email with a link to upload video has been sent to poster presenters.

Videos must be submitted by March 6, 2020 to be available during CROI.  Videos will not be accepted after March 11, 2020. The video must follow these specifications:

  • The video may not exceed 5 minutes in duration
  • Presenters should confirm the audio and video quality prior to submitting
  • The video should be submitted as a MP4 file
    • If submitting as an MP4 is not an option, alternate file formats will be accepted, but they must be formats that could be uploaded to YouTube. See Supported YouTube file formats
    • If your video is not supported by YouTube, it will not be supported on the CROI webcast portal
  • Presenters may test that their video is supported by uploading to YouTube. Review the YouTube Quick Start Guide for instructions on how to upload videos. Users may set their test video to “Private” so it will not be visible to other users on YouTube. See Change video privacy settings
  • You must agree to the consent form for release of the video on the CROI webcast site.
  • Technical questions may be submitted to

Instructions on how to record your narration and into your PowerPoint slides are available here.

Electronic Posters

Poster presenters are required to upload an electronic version of their final poster as a PDF file prior to the conference. The electronic poster will be available to attendees at the conference via the Mobile App and to the public after CROI. Questions about this requirement should be sent to

Electronic poster submission is now open. To upload the final version of your electronic poster, log in to the CROI Abstract Website and access your schedule in the Speaker Center. Then, click the Upload Presentation button by your poster presentation listing. In order for CROI attendees to view posters during the conference, please submit the final version of the electronic poster by March 6, 2020. Electronic posters will be available to the public after CROI.

Note: Please save the poster as a PDF in the smallest file size possible. Other file types are not supported.

Presenting Author Responsibilities

The presenting author is responsible for presenting the abstract at the conference and must be present at the poster during the entire session. If exigent circumstances require presentation by an alternate coauthor named on the abstract, please contact CROI immediately by email at

Requirements for Presentation Development

Presentations from randomized trials and cohorts should follow the International Committee of Medical Journal Editors (ICMJE) guidelines, including reporting of study designs, (eg, prospective, observational, randomized, double-blind, STROBE, CONSORT, or others), statistical methods, and outcomes by demographic variables. See the ICMJE guidelines for more details.

Appropriate information and correct terminology should be used with regard to sex and gender. For human clinical or epidemiological studies, sex-stratified results should be provided or who was included if it includes only a single population. Appropriate terminology such as cisgender (people whose gender match the sex assigned at birth) or transgender (people whose gender does not match the sex assigned at birth) should be used. Both sex and gender data should be provided in the presentation. Presentations of preclinical data including use of cell lines and animal studies should include the sex of the animals or the sex of the source of the cell lines. If data are not available on sex and gender, this should be identified as a limitation in your presentation.

Out of respect for their contributions to our scientific advances, avoid calling study volunteers “subjects.” The preferred terms are study “participants” or “volunteers.”

Please also note whether the study is ongoing or completed and whether the results are preliminary or final.

Publication or Presentation Prior to CROI

If your study data are accepted for publication or presentation after the abstract submission to CROI, and that publication or presentation is expected to take place before CROI, you must contact CROI at to provide details as soon as your presentation is accepted for review, presentation, or publication in another venue or outlet. Please be aware that, although publication in these circumstances will not necessarily prevent presentation of the research at CROI, our strong preference is that any additional publication or presentation happen either simultaneous to or following presentation at CROI. Requests to publish or present research accepted for presentation at CROI prior to its presentation at CROI will be evaluated on a case-by-case basis. Failure to notify the conference promptly regarding plans to publish or present a CROI-accepted abstract prior to CROI may result in the removal of the study from the conference program.

Format and Required Information

Poster material should be well labeled and legible from a distance of 10 feet. We suggest using the CROI Template for an Alternate Poster Design [hyperlink to the PPTX of the poster format].

Poster Title: The poster title should be the same as the title submitted with the abstract and appear in boldface at the top in either all capital letters or standard American Medical Association (AMA) title case (Nouns, pronouns, verbs, and other important words begin with uppercase letters; coordinating conjunctions, articles, and prepositions of 3 letters or fewer should all be in lowercase letters unless they are the first or last words in a title or subtitle).

Poster Number: The poster number should be displayed in the upper right corner (“0000” in the Alternate Poster Design template). This is not the abstract number you had during submission but a number you will be assigned and sent to you by email which notes the position of the poster in the poster hall. This number will be sent to you after late-breaking abstracts have been accepted in January

QR Codes Are Not Allowed: Please note that QR codes or bar codes are not permitted on posters displayed at CROI or on electronic versions of the posters to be uploaded to the CROI website.

Displaying Your Poster

The suggested size for your poster either 54 inches (width) x 36 inches (height) or 60 inches x 40 inches (137.2 cm x 91.4 cm or 152.4 cm x 101.6) based on using the CROI Template for a Better Poster Design [hyperlink to the PPTX of the poster format]. The minimum size for a poster is 36 inches (width) x 24 inches (height) so attendees can see the poster at a minimum of 10 feet away.

Maximum Size: The size of the board for displaying the poster is 96 inches (width) x 48 inches (height). The maximum size of a poster is 93 inches (width) x 45 inches (height).

The face of the poster board is covered with Velcro-receptive fabric. Push pins will be provided for to hang your poster.

Poster Printing

Presenting authors should print their physical poster based on the requirements listed in the sections above. CROI does not print posters on behalf of presenters.
