Poster design is a useful art to master for presenting information to others. Whether you are advertising a cause or sharing your research findings, a well-designed poster can be an effective way of presenting your information. Viewers tend to glance at posters very briefly before deciding whether to give them a closer look. To draw people in and effectively share your message, you must design an attractive poster that viewers will want to examine.
Identify your message and audience. Your poster should have one main point that it is trying to get across. If you try to communicate too many points in a single piece, the results will be cluttered and confusing rather than clear and effective. You should also consider your audience. If you are communicating with children, you will want to use few words. An academic audience will be more willing to read some of the more detailed text on the poster.
Use large fonts for any text on the poster. The title should be 85pt. or larger. Text should be no smaller than 24pt. Keep all writing to a minimum. Too much reading will turn viewers away and make for a boring and unattractive poster.
Select images with a resolution of 200 dpi or higher. Allow these graphics to dominate the poster. Select clear, obvious pictures that will show the audience what you are trying to get across. Avoid obscure images that will require viewers to carefully read a caption in order to understand what they are seeing.
Use a cohesive colour scheme. Pictures that incorporate several vivid colours will make your poster more attractive, but text in bright colours on coloured backgrounds will not. Use simple borders without wavy or jagged edges and stick to the same colour for all borders on the page. Dark text on a very light background is easiest to read.
Allow enough blank space between elements to keep the poster from looking cluttered. Columns and rows should be clearly separated by empty space, not filled with graphics. On the other end of the spectrum, you can take white space too far if there is more space around an item than the item itself actually takes up. The majority of the poster should present images or information. A single picture floating in the middle of a vast emptiness will appear unsettling and will not be attractive to your viewers.
