What is a science poster anyway?

So what’s a science poster anyway? It’s not a commercial poster, obviously, but what is it exactly?

So as I’m pulling my hair figuring out how to fit everything into the space, I suddenly realized a science poster is an exhibition design problem. What it is, really, is a 48″ × 36″ 2D exhibition space, complete with artefacts (photos, illustrations, charts and tables) and integrated explanatory panels.

No wonder font size adjusted for anticipated viewing distance is so important. We aren’t really designing posters; we are actually designing mini exhibits.
