Hello all guys! Welcome back to word.rean.me by Rean Computer 101! Today I show you how to use and manage Slide Master and apply multiple design themes in Microsoft PowerPoint!


Step 1: How to Open & Edit Slide Master

Slide Master controls default fonts, logo position, colors, and layout templates for your entire presentation:

  1. Go to View tab on top ribbon menu > click Slide Master.
  2. Left side panel shows top parent master slide and child layout templates.
  3. Click on top main parent master slide:
  • Insert company or school logo at top right corner.
  • Set master title font (e.g. Khmer OS Muol Light) and body font (Khmer OS Battambang).
  • Format footer text and slide number color.
  1. Click Close Master View button on top ribbon. All existing and new slides will update formatting automatically!

Step 2: How to Apply Multiple Design Themes in 1 File

If you want different slide sections to use different background color themes:

  1. Select specific slide thumbnails on left panel (e.g. slides 5 to 10).
  2. Go to Design tab on top bar.
  3. Find your preferred theme in Themes gallery.
  4. Right click on theme thumbnail > select Apply to Selected Slides (do NOT left click directly or it changes all slides!).
  5. Now slides 1-4 use Theme A and slides 5-10 use Theme B in same presentation file!

Step 3: How to Create Custom Slide Layout Placeholders

  1. In Slide Master view, click Insert Layout button to create new layout.
