  • Confirmation will also be given as to whether it will be an oral presentation or poster.

Poster Format

  • All posters should be a visual presentation of your submitted abstract and they should meet the following criteria:


  • The poster must be no larger than A0 size (AO size is 841mm x 1189mm)
  • Orientation of your poster must be in portrait style.


  • The title should be the same as in the submitted abstract
  • 20-24 mm or 100 point maximum
  • Upper and Lower Case
  • At the top of the poster include the title of the presentation, the name of the authors and the institution where the work was completed.


  • 48 point is suggested – 60 point maximum
  • Title Case Headings such as “Introduction”, “Methods”, “Results”, “Discussions” and “Conclusions” are useful

Content Lettering

  • The poster should be easily readable at a distance of two metres. Use UPPER and lower case for general content as the use of all-capital text is difficult to read. Avoid using a mixture of type/font styles
  • 24-28 point – 32 point maximum
  • Single spaced Upper and Lower Case
  • The text should be brief throughout
  • Any description of methods should be simple and concise


  • The message that your poster contains should be clear and understandable without the requirement of oral explanation.
  • Methods should be presented simply and concisely
  • After the title, the two most important panels are the Introduction and the Conclusion.
  • On the basis of these two panels, a reader will decide whether to consider the poster details and perhaps talk to the presenter.
  • These panels need to be very simple, concise and visually attractive
  • Results should be presented graphically if possible. Avoid large tables of data. Results should be in line with those originally submitted in your abstract
  • Use pictures, symbols and color. Figure legends are essential and should be short but informative
  • Each graph should have a short heading. For visual effect, we recommend that graphs be no smaller than 12cm x 18cm.
  • A matte finish on photographs gives better visibility. Photographs should be no smaller than 12cm x 18cm.
  • Use the space to attract your audience for discussion, not to present complex details of methods and results
