Because research posters are often viewed in crowded, social environments, they must present core ideas simply and clearly. Text should be large, such as $72$ points for the title and $28$ points for main content, organized under clear headings using short sentences or bullet points instead of dense paragraphs. Content should flow vertically in columns to allow multiple people to read simultaneously without crowding. Additionally, presenters can enhance visual interest by using colorful figures, photographs of apparatuses, or copies of visual stimuli, provided purely decorative elements are not overused.
