Smart Science – using design principles to inform scientific posters

November 2017

When it comes to communicating science, there’s a lot to think about. Design is an important and often overlooked aspect —many researchers focus most of their efforts on content.

But design deserves at least equal, if not more, attention. Fortunately for scientists, design is a science and can be learned. Get more scientific with your design — it’ll help you get a message across.

Posters are a popular way to showcase new research to the scientific community. The use of intelligent design principals is vital to maximise the impact of your poster. Here’s some advice for making better posters.

Text and tables

This is where most of what you want to say will be displayed, the right design and layout here is vital.

  • A large block of text is not inviting to anyone
  • Each section of text should be clear and concise, focusing on a single area.
  • Five to six lines of text with 25-30 characters per line is generally best. Use bullet points to break up sections and highlight important points.
  • A large font (minimum 24-point size) is important so that the text can be read from at least one metre away.
  • Poster text should be organised in columns — this helps your eyes move less as you read.
  • There should be a good balance of text, diagrams, tables and graphics. Avoid large blank areas.
  • Tables and figures with colours are more engaging and exciting to look at and are often a clear and easy way to show complex information. (But be careful with what colours you use.)
  • Black text on a white background is often the easiest to read.

Colour is important and should be considered carefully. Opposite colours tend to make a bold — if potentially clashing — statement and are therefore more likely to catch the eye of a passing delegate. But use your best judgement on making something look good first and striking second. Studies of Event Related Potentials (a measure of neural activity related to cognitive and sensory processes) have shown that higher attention is paid to yellow- and green-based colours.

Light at a conference is important to consider. Although glossy laminate may look better, opting for a matt lamination ensures everyone will be able to see it regardless of how much light you have. Many conferences or universities have set guidelines as to the layout and size of posters. This is always an important thing to consider: a rectangle in a sea of square posters stands out for the wrong reasons.

What happens when you’ve grabbed someone’s attention? In terms of information content, a study comparing the effectiveness of different methods of health education found that found that more specific topics were preferred over broad coverage, suggesting that it is better to pick a small area of research to focus on rather than attempting to cover an expansive topic.

Surveys have shown one to one discussions are more valuable, with 55.4% of conference delegates preferring individual discussions with authors about the posters rather than moderated presentations. This is the most important chance to discuss your research as it gives you the opportunity to discuss things that have not been included in the main body of the poster and gives you opportunities to answer questions.

Posters may not currently be the most valued way of showcasing results, but with the help of intelligent design, posters can be revolutionised! Posters are and will remain a vital part of scientific conferences. So next time you have a poster to design, consider the use of science to guide you.
