Professional Poster Construction

Graphics & Images

Images:

  • should be at least 5" X 7" in size.
  • should be cropped to eliminate unnecessary information and focus the audience's attention.
  • should be enlarged if necessary to provide sufficient detail.
  • should include captions - your audience will see what they are told to see.
  • from the world wide web, when printed large on a poster, may have large pixels that distort an image.
  • that are scanned for a poster should be 300 dpi (dots per inch).

Graphs:

.

  • should be simple and clean.
  • should be 2-dimensional unless you are displaying 3-dimensional data.
  • should have an information ink to total ink ratio as near to 1:1 as possible (Tufte, 2006). Colored backgrounds, grid lines, elaborate axis labels, and other unnecessary ink on a graph detract from the data and pattern plotted on the graph.
  • axes should be selected such that the plot of the relationship of the data makes sense. The X-axis, for example, should be the independent or predictor variable and the Y-axis should be the dependent or criterion variable.
  • should be captioned rather than referenced in the narrative portion of the poster.
  • should be of the appropriate type to communicate information quickly and easily (e.g., a line graph to illustrate an interaction, a bar graph to illustrate differences between groups, a pie chart to illustrate proportions of a whole).
  • should illustrate your data with integrity and truthfulness. Data should be graphed in context with adequate explanatory labels and proportional scales. Time series data involving money should be adjusted for inflation.
