Poster Session Guidelines

  • All materials must be confined to:
    - Convention Center: 4' high by 8' wide display board
    - Hotels: 4' high by 6' wide display board
  • Authors must mount their poster during the one hour before the scheduled session start.
  • Poster numbers supplied by ACS will be in the upper corner of each poster board. This number corresponds with the number assigned to each poster in the technical program.
  • Pushpins will be available at the poster session.

  • All posters must remain up until the session ends; they must be removed within one hour. ACS cannot assume responsibility for materials beyond these time limits.

What to Bring

Speakers need to provide their own laptops or arrange for specialty equipment directly with their symposium organizer and/or division program chair. To request other specialty equipment (at the standard fee), contact an ACS Operations Office during the meeting.
