The design of the page is also important. Use standardized indentations and capitalizations to provide visual cues. Only use all capital letters in short titles or to label a visual. The use of all capital letters gives readers the feeling of being shouted at. Smaller blocks of copy, horizontal and vertical divisions, and shorter lines of five to six inches increase readability.
Columns afford maximum use of white space.
Margins, with the exception of the interior margins of bound publications which are often in a shadow, don't have to be more than one-quarter of an inch. Straight left-hand margins are helpful, but right justification has little impact on the visual effectiveness of a page. Lastly, consider how the publication handles. To help clients compensate for decreased abilities to focus and recognize images, it's important to apply these publication clues to any teaching tool that involves seeing. When planning posters, slides, and overheads for a presentation, the same principles of contrast and identification apply.
