This document provides guidance on creating effective scientific posters. It discusses key elements like having a single, focused message; using graphics to tell the story; and having a well-ordered sequence. The planning process involves knowing conference rules and judging criteria, choosing a layout, and editing text carefully. Effective layout avoids clutter, uses simple lettering and colors, and doesn't fight reader gravity. Presenters should bring a poster hanging kit, extra copies, and business cards when presenting and be prepared to discuss their work.
