Layout is as important as the science itself - keep it simple.
Exceptional layouts, graphical details, or interactive parts should enhance the understanding of the results.
Challenge your layout by involving your colleagues, e.g. print a version and hang it in the hallway to get feedback.
Not all information can be visualized in exactly the same way. Something compelling on A4 does not automatically work on A0 and vice versa.
Your genuine enthusiasm in presenting your research and your ability to explain the results is very important, but respect that some audiences just want to read the poster and not engage in a long discussion.
Check out these websites for further instructions and inspiration: Designing conference posters and Better posters.
Posters can be in portrait format only. Posters in landscape format will not be exhibited. The dimensions of the poster should be maximum A0 size (84.1 x 118.9cm). Fittings will be provided.
Read the detailed poster guidelines.
