As a concise visual communication tool, the poster enables your inclusion in the circuit of ideas during the conference without your physical presence.

The posters will be presented in the lounge in front of the main Conference Hall 114 during the conference days.

For this reason, the poster should be regarded as a visual and verbal presentation of the submitted abstract and it should meet the following criteria:


All verbal elements should appear in both, English and Bulgarian languages.

TITLE & Subtitles

Include the title of your presentation at the top of the poster. The title should be the same as in the submitted abstract. Characters should be a minimum of 48 to maximum 100 point font size. Your name(s) and institution(s) should also be displayed on the poster. Optional: if you wish, you may leave some contact details: e.g. email, website. Use 48 to 60 point font size for subtitles. You can also allocate a specific colour to the titles and subtitles within the poster so that they will be better distinguished from the text.


The poster should be easily readable at a distance of approx. 1.5 metres. Use Upper and lower case for general content as the use of all-capital text takes 10% more time to be read. Preferable type/font styles: Georgia, Open Sans or Helvetica, but avoid mixing them.


24 to 32 font size lower case single spaced is recommended. The text should be concise and easy to read. Avoid abbreviations. The message that your poster contains should be clear and understandable without the

requirement of oral explanation. If relevant, methods, approaches and results should be presented simply and briefly.

Generally, the poster should be designed to attract the audience to your main message / key idea, not to present all complex details of your work.


Posters are first of all visual presentations. As such, it is good to keep in mind that graphs, charts, photos or tables are particularly eye-catching. It is often considered that around 50% of a poster should be dedicated to illustrations. Use figures, symbols and colour. Figure legends should be short, but informative. If using graphs, they should have a short heading.

Preferably the main visual elements – graphs, charts, diagrams, photographs, etc. should be no smaller than 12cm x 18cm.

Use pictures or images of sufficiently high resolution and of good colour and contrast (not too dark, not too light) in order to ensure good quality print. Be sure to use pictures without copyrights.

Major colours that are easily readable are:

Black / Red / Green / Blue on white or a cream coloured background. If you prefer a different setting make sure it is easy to be perceived.


The poster should be prepared in  portrait  orientation  to  fit  A0 size (841mm x 1189mm), and should be sent as digital PDF file to the organizers who are going to print and prepare the  posters  for  exhibiting.
