Draft several alternative texts for posters and ask a wide range of viewers to tell you which ones seem clearest. You won't need to draft the entire poster for your samples. Instead, focus on one or two key sections—perhaps the text that defines the topic or scope of your poster and the section that explains what viewers should do now that they've read the information on your poster (for example, the text that describes how to stop spreading a common infection among school children). Try out your alternative versions on a few readers with the same level of background knowledge you expect of viewers of your poster. Ask specifically about which version makes the most sense or seems most interesting.
