Poster clinic: Simple design is best

Part 3 in a series

Rows of postersNow that you have your text ready, it is time to work on the design of the poster. This can be done in many ways. Most people will start from a template they found online or provided by their institution. These are very handy if you don’t have much time or little design skills. But since almost everyone is using very similar templates, you see that posters often look alike.

For example, as you see in this picture, most posters tend to be in blue and white. Although this is a very quiet color combination that makes for comfortable viewing, it does not help attract the reader’s attention the same way green or warm color accents might have done.

Another issue is that templates tend to be organized into columns, which are very inviting to fill with text. If you use a template, make sure to avoid columns and work with smaller blocks of text instead. These also give you much more freedom to adapt the design to the specific needs of your message.

Personally, I start by choosing an essential figure and putting it in large format in a very central position and building everything around that. Next, put the different text sections (Purpose, Methods, Results, Discussion, take-home message) in separate boxes and place them in logical positions around the central figure. Make sure each box is titled, numbered and has a similar design (e.g. same color and width) to ensure the reader immediately understands how to navigate your poster. Using such boxes will allow you much more freedom in your design. Once the boxes are roughly where you want them to be, add the title and other elements (bibliography, extra information). At this point you should have a rough idea of the layout, although the shape and positions of the objects may still change.

Now it is time for the artistic part. In this area I cannot guide you too much, that is up to your inner artist, but here are some guidelines:

  • Color is a very powerful way to attract attention and should be used sparingly. Limit the number of different colors on your poster and work with complementary colors. The combination of greyscale and accent colors work great as well.
  • Choose a different design for poster elements according to their content (e.g. text boxes are square and red, extra information grey, etc.) to indicate their relative importance.
  • Think about colorblind readers. To those with red-green color blindness (about 5% of the population) blue-green and magenta-violet will appear grey and indistinguishable from one another. For your convenience, here is a simulation of how they experience colors.
  • Make sure the text contrasts strongly from the background for easy reading. Avoid using text with a textured background.
  • Use a maximum of two font types that are easy to read, such as sans serif fonts (e.g. Arial, Calibri, Verdana, etc.). Never use Comic Sans!
  • Ensure that the figures have a sufficiently high resolution to avoid pixelated images. It is preferred to use vector graphics (e.g. Excel graphs imported into PowerPoint).
  • Verify that all the design elements (text blocks, figure blocks, etc.) are aligned with each other. Most software packages have automated tools for this purpose.
  • Make sure font sizes are large enough to read comfortably from a discrete distance. Important text should never be smaller than 28 pt.
  • Do not use the logos of entities you are not associated with, such as ARVO or companies, to avoid giving the impression that they endorse your work.
  • Instead of classic handouts, add a QR code linking to a pdf version of the poster. There are plenty of great websites that let you make a QR code for free. Use a link shortener such as Bit.ly to avoid having to add a large, complex looking block to your poster.

Here are a few of my old ARVO posters based on these principles for inspiration:

To make the design process more concrete, let’s consider a typical ‘wall of text’ research poster and see how we can improve it step-by-step.

Poster

Looking critically at the contents, you will see that much of the text is not essential. Some parts state facts that your target audience is likely to already know. Other parts are repetitions and some parts are just fluff to make it sound better. We start by taking out these parts, along with the unnecessary abstract section and one unimportant image, keeping only the parts in green. The numerical data in the Results section can be turned into a table that is a lot easier to understand. The title can also be simplified.

Poster example

In the reorganized poster, the essential elements such as the main figure and the take-home message should stand out. For example, feature the figure very large in the center and give it a light orange background. The title and take-home message can be put in a bright orange box with a large font. Aspects that are less important for your personal storytelling (e.g. text blocks) should go into white boxes on the side of the figures. These don’t need to stand out, just like the eye image that can be in greyscale. The extra information, which is least important, goes in a grey box somewhere out of the way. The resulting design will make all the main points in your story stand out immediately, even if you are not there to talk about it.

It doesn’t take much work to create a better-looking poster…

Poster example

Since people are often visual learners, make sure to bring anything that can help visualize your research story. If you present a new app, show it on your phone. If your work involves virtual reality, bring a VR headset. If it is about a molecule, bring a model. A time series of pictures can be turned into an animation on a tablet, etc.

Also, don’t be afraid to do something original with your design! At the 2014 ARVO meeting our research group featured a round poster. This simple idea made it look so different from all others that it stood out from a distance and attracted lots of attention. In another field someone even made an entire comic poster of her work.

Original post design

One final tip is to make sure to practice your poster talk as a 30-second elevator pitch and a longer, two-minute version. The better you are prepared, the better you will be able to tell your story.
Good luck!
