In choosing a layout you'll want to keep these issues in mind. You can find more examples and discussion in the sources under the Helpful Resources tab.

• the story of your presentation should be readily apparent and easy to follow
• the most important parts of your story should appear in the most prominent locations
• the sequence of your presentation should be obvious and natural
• take advantage of natural eye movement patterns - top to bottom and left to right in English
• don't overcrowd - leave blank space to separate the sections of your poster
• leave margins around the edges
• limit text to short blocks
• title should be prominently displayed at the top
• authors' names, affiliations, and contact information should be readily visible near the title

You may choose to design your poster from scratch, but sometimes a template that may fit your needs already exists . Check out examples of real posters to get ideas that may work for you.
