Poster sessions provide a forum at ASCO meetings and co-sponsored meetings for informal discussion between researchers and attendees. Designing an effective poster gives attendees an opportunity to learn about your research in an easy-to-understand format. The tips below will give you the tools you need to assemble an impactful poster.

Size Limitations for All Posters

 Posters presented at ASCO meetings and co-sponsored meetings can be no larger than 47-inches high and 95-inches wide (120 cm high by 240 cm wide). This is the size of the poster board. For those preparing posters, please do not exceed the size of the poster board.

Suggestions for Formatting Your Poster

  • Write your presentation concisely and keep captions brief. The poster should be self‐explanatory so that you are free to supplement the information and discuss points raised by questions during the poster session.
  • Format of poster is LANDSCAPE (horizontal).
  • Place heading in large‐sized type at the top of the board.
  • List the title and all authors. 
  • All material should be readable from distances of three feet or more.
  • You are strongly encouraged to use a type that is at least 3/8" high (22 pt. minimum).
  • Use bold type to ensure legibility.
  • Make all print very dark (preferably block style) on a very light (preferably white) background. Use letters, arrows, numbers, or other devices to show those who will be viewing your poster the preferred sequence in which your poster should be reviewed.
  • Charts, drawings, and illustrations should be like those you would use in making power point slides.
  • If photographs are used, have them processed with a matte or dull finish.
  • Please clearly print one email address on your poster for attendees to refer to should they have any questions or comments at a time when you are not standing with your poster. If you do not wish to print your own email address, please list another email address for an appropriate contact person for your abstract.
  • The poster can either be made on one sheet (rollup) or in several small sections. Do NOT mount illustrations on heavy cardboard because they may be difficult to keep in position on the poster board.

Inclusion of Quick Response (QR) Codes

If you choose to include a Quick Response (QR) Code on your poster, you must also include the following disclaimer on both print and electronic versions of your poster: "Copies of this poster obtained through QR Code are for personal use only and may not be reproduced without permission from ASCO® and the author of this poster." Written authorization is not required, unless your QR code links to the full text of your abstract, which would be considered a reprint.

Special Note on Use of Commercial Materials

ASCO is committed to minimizing commercial bias in poster presentations and handouts. Poster presentations and handouts should not contain any of the following: commercial logos, company names, or brand or proprietary drug names. Cooperative groups, hospitals, and non-profit company logos are permitted.
