This document provides guidance on designing and presenting scientific posters at conferences. It discusses that posters are a visual medium to communicate research to attendees walking by. Key considerations for an effective poster include having a clear layout with sections like introduction, methods, results and conclusions. Fonts should be large and easy to read from 1.5 meters away. Graphics and minimal text are important to convey the main messages quickly. The poster should be designed so specific sections are easy to locate. When presenting, authors should speak clearly and concisely about why their research is important without reading the poster directly. Practice and feedback help improve the presentation.
