Graphs and diagrams should be easy to read. Leave space around your graphics. Choose graph types that are appropriate to the information that you want to display Use a legend Label everything - the axes, the legend, the graph itself, etc. However, all lines should be thick enough to be viewed from a distance. Only use pictures and clip art when they add interest and complement the subject matter.
Tables Keep it simple and limit the length of the table.
Use keywords or key phrases, not sentences. Leave space around the table. Equations Should be kept to a minimum. Use the same method for emphasis throughout the poster Make graphs the same size, especially if they are to be compared. Captions for graphics should be at either the top or bottom of the graphic.
