While changing the Slide Layout for any given slide(s) in PowerPoint 2016 for Mac, you typically access the Home tab of the Ribbon and click the Layout button. This brings forth the Layout drop-down gallery, as shown in Figure 1 below. The number of Slide Layouts that you see within this gallery may differ depending upon the Theme of your active presentation. However, with PowerPoint's default Office Theme applied, you may see 11 layouts (refer to Figure 1, again).

So, where do these Slide Layouts come from? What influences how they look, or how the placeholders within them are laid out? To find out answers to these questions, you need to access Slide Master View within PowerPoint.
In Slide Master view, you'll find that the left pane contains two distinctly different elements: a larger thumbnail representing the Slide Master (highlighted in red within Figure 2) and several smaller slide thumbnails below representing individual Slide Layouts (highlighted in blue within Figure 2).

In any typical PowerPoint presentation, the Slide Master (highlighted in red within Figure 2, above) is hierarchically placed at the highest position for information about the background, color, fonts, effects, placeholders (size and position), etc. The Slide Layouts which are placed at a lower hierarchy level get all this information from the Slide Master they belong to.
When you modify the Slide Master, you are making changes to all the influenced Slide Layouts beneath that Slide Master. For example, if you change the Background Style in a Slide Master, this should reflect the new Background Style in all the dependent Slide Layouts. However, the reverse is not true. If you make any changes to the Slide Layout, that change is never reflected in the Slide Master. In fact, for that change in particular, the Slide Layout stops being influenced by the Slide Master. Exploring our earlier example of changing the Background Style, any change made to the Background Styles in a Slide Layout will not affect the Slide Master or any other Slide Layouts within the presentation.
The eleven Slide Layouts available within the Slide Master are:
- Title Slide Layout
- Title and Content Layout
- Section Header Layout
- Two Content Layout
- Comparison Layout
- Title Only Layout
- Blank Layout
- Content with Caption Layout
- Picture with Caption Layout
- Title and Vertical Text
- Vertical Title and Text
