Poster Guidelines

Each poster board will be VERTICAL with eight-foot-high x four-foot-wide (243cm x121cm) of usable space. In addition to the board a sign indicating your paper final ID and push-pins will be provided.

Presenters should display the paper title and authors and affiliations on their poster. Please note that poster papers are not supplied with electricity or audiovisual equipment.

Poster Session Schedule & Set-up/Tear Down

Posters must stay up the entire session time, as attendees will be visiting the posters during the entire session period.  If a poster is removed before the conclusion of the session it may be considered not presented and will not be indexed in Ei Compendex or Scopus. Authors should remain in the vicinity of their presentation board for the entire duration of the session to answer questions from attendees. Also, the presenting author should remain with the poster for the majority of the session time.

There are three (3) Poster Sessions for CLEO. All poster sessions are held in the Exhibit Hall.

Authors should set-up their posters during the times listed below, for the corresponding session. All presenters must remove their posters at the conclusion of the session. Management will discard any remaining posters after the time listed below.

Suggestions for Poster Format

Posters should be readable by viewers five feet away. The message should be clear and understandable without oral explanation. The following guidelines have been prepared to help improve the effectiveness of poster communications.

Initial Sketch

Try various styles of data presentation to achieve clarity and simplicity.

Rough Layout

Enlarge your best initial sketch, keeping the dimensions in proportion to the final poster. The rough layout should be full size. Print the title and headlines. Indicate text by horizontal lines. Draw rough graphs and tables. This will give you a good idea of proportions and balance. If you are working with an artist, show the poster layout to your colleagues and ask for comments. This is still an experimental stage.


The figures and tables should cover slightly more than 50% of the poster area. If you have only a few illustrations, make them large. Do not omit the text, but keep it brief. The poster should be understandable without oral explanation.


Resist the temptation to overload the poster. More material may mean less communication. Prepare an 8-inch high headline strip that runs the full width of the poster. Include the title, authors and affiliations on the strip in letters not less than 1-inch type. Post a large typed copy of your abstract.
