Please Be Advised:

Upload your Poster file ahead of the deadline if you need to coordinate the audio recording in a timely manner.


Please make sure you include your new abstract number that you have received in your abstract notification on your poster. ISTH will provide each presenting author with the abstract presentation number once confirmation has been received.


  • Please make sure you include your new abstract number that you have received in your abstract notification on your ePoster.

  • The poster should be readable from a distance of 1.5 – 2 meters (4 – 6 feet).

  • The text should be no less than 8 mm (22 point font) and preferably larger.

  • Use a constant font throughout the poster.

  • Use a black and bold type to ensure legibility and let your important points stand out.

  • We suggest that you show the preferred sequence in which your poster should be reviewed; this can be done by using 3 – 5 columns so the eye movement is down the columns.

  • Highlight your main findings. Don’t hide your conclusions, consider putting them at eye level, at the top of the right column or alternatively start with the Conclusions. Otherwise, we suggest that you structure your poster by Introduction, Methods, Results, and Conclusions. State your aims in the end of the introduction.

  • The figures and tables should cover approximately 50% of the poster area.

Other Recommendations:

  • If possible, avoid abbreviations and acronyms, especially in the Conclusion section.

  • Seek simplicity, keep text to a minimum and avoid redundancies.

  • Feel free to provide one or more key references.

  • Prepare a short (< 60 seconds) oral guide through your poster to be offered to those that prefer your words before reading for themselves.

  • Handouts of your abstract/poster are allowable. We encourage you to include your email address on your poster or handout, so anyone interested may contact the abstract author about questions, comments, or future research inquiries.

Audio Recording FAQ

  • Is there a deadline for audio narration recording?

  • If I submit before the deadline but then need to re-upload with new edits, am I able to do so?

  • If I re-upload a new ePoster, will my old audio files be deleted?
    No. The audio will remain the same unless a section of the ePoster is removed.

  • Are you limited to the number of narrations you can use?
    One per section maximum.

  • Can you narrate specific figures? Or only the larger sections in the ePoster template provided?
    Any section can have narration (except if you send us a video to add on a section).

  • Is there a time limit on the recorded narrations (per section or overall)?
    No. But please keep it short and concise.

  • Can audio files be uploaded?
    No. The audio must be recorded online in order to be directly uploaded in the correct format on the correct section.

  • When can I add audio narration?
    After you submit your ePoster file, we will process it to an electronic poster. This can take a few hours to a few days depending on the volume we receive. You will receive an email once the audio narration is ready to be recorded.
