Templates for better posters

There’s been a frenzy of discussion on Twitter this summer about conference poster design (see #betterposter, #betterposters, #butterposter) so perhaps it’s a good time to re-share my Powerpoint templates. If you’re new to posters please see my page, “Designing conference posters” for details.

Below is a standard horizontal template. I recommend 500-800 words and 1 or 2 graphics that are understandable without you needing to explain them.

Note that there is no requirement for the text boxes to have a line around them — it’s easy to set line width to zero. And if you want to delete the background color (gray, here), you can eliminate the “rectangles within rectangles” look. Totally up to you.

If you want to include a QR code, put it at the bottom so that it doesn’t distract from your interesting graphs and illustrations. Like this:

But be cautious about including a QR code. By design it invites a viewer to fire up their camera phone, and I’d wager that most will also take a pic of your entire poster. So skip the QR code if you don’t want people to take pics of your poster. A compromise is to print business cards that have the QR code (as well as poster title, your name, your email address) and then leave them in an envelope pinned next to your poster (“please take one!”).

Here’s a template that moves the Literature cited, Acknowledgements, and Further information to the far right column … which causes the Materials & methods and Results areas to have more room. But the Conclusions box gets squished (such is geometry).

Here’s a template that might work for a humanities topic. I’ve chosen to have a question/result/conclusion flow (from left to right) inside the main arena, but you can always rearrange. There are also no rules about section names — just redo those, too.

The final template is a portrait-style one. For this orientation I think it’s critical to put the least important sections on the very bottom (that position is really hard to read without stooping).

If you’d like to read an article about the better posters frenzy, here’s one from Inside Higher Education in which I’m quoted a few times.

Killing mosquitoes with autocidal gravid ovitraps

In case you are looking for a way to kill mosquitoes without sprays, here are three types of traps that kill pregnant (gravid) mosquitoes that are searching for water in which to oviposit. Each is filled with water and decomposing plant matter (hay, compressed rabbit food, or leaves), then equipped with special lids (and sticky cards) that prevent females from escaping once they get inside. In addition to killing the females, any eggs that the female might lay are also prevented from developing by the presence of screens that trap the emerging mosquitoes from escaping. All of this happens passively, 24/7, all summer long, without the use of chemicals.

I have two from Biogents, two from BioCare (which look like these), and one that I made (instructions). They all work great but the DIY one seems to catch the most mosquitoes so far.

Every homeowner should have them. Coupled with other preventative measures (eliminating stagnant water, reducing excess vegetation, etc.), you can knock back mosquito levels and enjoy your yard again. Five units is probably sufficient for an average yard but I plan on making a few more this summer just to make sure.

Ideally, everyone on your block should have them, too, so if you are planning on ordering some you should first send a note to all your neighbors to see whether you can make a bulk order. E.g., if you order a lot of Biogents you can shave a few dollars off of each unit (e.g., Amazon has bulk-order option). Buying a bunch might seem like a lot of money but compare it to the cost (~$700) of having a company like Mosquito Squad spray your yard with pyrethroids every several weeks (every year). Using these passive traps also saves all the pollinators that are killed by those pesticides.
