Font Size and Lettering Use at least 36 point font for your text and 48 point font for the title. Avoid using italicized or fancy scripts. Highlighting with colors or underlining important information is acceptable, but make sure your font style is consistent over the entire poster. Avoid using all capital letters except for the title. Handwritten posters appear sloppy and imply that not much effort went into preparing the poster.
Viewers typically expect information to flow from left to right and from top to bottom.
If you want to use a different flow, be sure to give explicit signals on your poster. Use headings and subheadings to label information. Keep these short and to the point since they function as an index. Use the same margins on both graphics arid text. Don't use glossy paper because reflections will make the content more difficult to read.
