Sometimes PowerPoint users forget that changes to features, like bullet styles and indentations, don’t have to be made on every slide—they need be made only once, on the slide master. The PowerPoint slide master stores information about the theme and slide layouts of presentations, including backgrounds, colors, fonts, effects, placeholder sizes, and positioning. Using the slide master can give you peace of mind as you make a presentation, because you know your slides will be consistently formatted.
Note: These slide master instructions are for PowerPoint 2010 and PowerPoint 2007.
To make changes to PowerPoint themes or layouts, from anywhere within your presentation, click the View tab, and then click Slide Master. You will see a slide master, as shown here.
The PowerPoint slide master stores information for your entire presentation.
The slide master includes placeholders showing the layout of text on the slides and the style in which text will be formatted. The slide master includes corresponding layouts to accommodate different types of information. You can apply a layout to a selected slide in Normal view: On the Home tab, in the Slides group, click the arrow next to the Layout icon.
Remember that changes you make to the layout or formatting on the slide master are automatically applied to all the slides in your presentation. If you want to change the placement or text styles for a specific slide only, select that slide, and work in Normal view. Then, make any of the types of changes mentioned here.
To change the bullet style for all first-level bullets in a presentation, make the change on the slide master:
From anywhere within your presentation, click the View tab, and then click Slide Master.
Click anywhere in the first bullet.
Click the Home tab.
In the Paragraph group, click the arrow beside the Bullets icon and then click Bullets and Numbering.
Select the bullet style and attributes you want for your first-level bullets, and then click OK.
You can change the style for all first-level bullets in your presentation.
In a similar way, you can make other adjustments to the style and format of the slide master, using formatting options on the Home tab. For example, you can change the text color and size, and you can change the indentation of the bullets from the Paragraph dialog box.
You can use slide masters for a lot more than adding repeated information or changing formatting, too.
