  • Boost Readability: Ideal for big screens or virtual presentations where clarity matters.
  • Enhance Visual Appeal: Mixing line weights adds depth and makes your slides look more polished.
  • Maintain a Unified Style: Consistent line thickness supports a clean, professional layout.

If you are already customizing your slides with borders, you might also want to add a border in Google Slides or draw freehand on your slides.
