Use master-level guides to align objects across all slides

Master-level guides are color-coded, fixed guides that you set in the slide master. Just slide them into place. Then, as you work in Normal view, you can align slide objects with these guides to help you achieve visual balance across all slides.

On the View tab, check Guides, check Ruler, and then click Slide Master .

Tip: Showing the Ruler (in addition to the Guides) can help you to better measure how far apart you want to place your guides.
At the top of the left pane, click the slide master.
One vertical guide and one horizontal guide appear to start with.
To add more guides, right-click anywhere on the slide master, point to Grid and Guides, and then click either, Add Vertical Guide or Add Horizontal Guide.
To move a guide, rest the pointer over it, and when the pointer becomes a two-headed arrow ( or ), drag the guide to where you want it.

Note: When you drag a guide, a tag appears near the pointer (below) showing the distance to the center of the slide.
To color-code the guides, right-click a vertical or horizontal guide, point to Color, and then click a color.

Tip: To delete a guide, right-click the guide and then click Delete.
