Design for context

Keep the context in mind when creating your slides. In a presentation, your slides should complement your spoken words. Use them to display visuals like charts and graphs, highlight key takeaways with large text, and reinforce your main points.
As a handout, slides become a reference document. In this case, include more detailed information, data, or explanations to ensure they stand alone.
If your slides will serve both purposes, consider creating two separate versions tailored to each context.
