Mini Lesson

A digital poster is a visual design created on a computer or tablet to share information or an idea. An infographic goes further — it combines text, icons, and data in a visual layout to explain a topic clearly and quickly. Tools like Canva, Google Slides, or even drawing apps can help you make both.

Poster vs Infographic

  • Poster — usually promotes an event, idea, or message with a strong visual and a short headline.
  • Infographic — shows information step by step or in sections, using charts, icons, and labels.
  • Both use color, fonts, and images to communicate clearly.

Key Design Principles

  • Contrast — use colors that stand out against each other so text is easy to read.
  • Alignment — keep text and images lined up neatly, not scattered.
  • Hierarchy — make the most important text larger or bolder.
  • Whitespace — leave empty space around elements so the design breathes.
  • Consistency — use the same font and color style throughout.

Steps to Create a Digital Poster

  1. Choose your topic and decide on a key message.
  2. Open a design tool and select a poster or infographic template.
  3. Add a headline — make it short, bold, and eye-catching.
  4. Insert text boxes with key facts, keeping sentences short.
  5. Add images or icons that match your message.
  6. Choose a color palette — two or three colors work best.
  7. Review: Is everything readable? Is the layout balanced?
  8. Save and export as PNG, PDF, or JPEG to share.

💡

Less is more in design. Too much text or too many colors makes a poster confusing. Pick your most important information and keep everything else simple.
