Arrange materials in vertical columns rather than a horizontal row format. It is easier for viewers to scan a poster by moving systematically along it rather than a zig zagging back and forth in front of it. 24 Title and subtitles should be in capital letters, although the authors and affiliations in the main title can be lower case to accentuate the title. General text should be in lower case and double-spaced, as this is much easier to read. General text is most easily produced by photographic enlargement of typewritten text or by personal computers with word processing programs equipped with large font sizes.
Complex graphs are too difficult to read and comprehend.
Simple use of color can add emphasis effectively. Detailed information should be provided in a legend accompanying each graph. Photographs and micrographs should have good contrast and sharp focus and should not contain unnecessary or distracting detail. Remember that they will be viewed from a distance of from 3 to 8 feet and should be large enough to be understood from that distance. Important objects should be labeled, and there should be clear indication of scale.
