Tips

Legibility is of paramount concern for presentation fonts.
Professional designers usually recommend a sans serif font for body type. Some instances of body type are fairly small, such as in table data or chart labels, and sans serif fonts are more legible in smaller sizes than serif fonts are.
Serif fonts are suitable for heading fonts.
Professional designers usually suggest that if you'll be sharing your presentation with others, don't be creative in your font selections. If a font you use isn't available on other peoples' computers when they view your presentation, a different font will be substituted for the missing one, causing text to be resized or misaligned.

The Create New Theme Fonts dialog box lets you choose from fonts that are already on your system. To learn how to download a font to your system, see Download and install custom fonts to use with Office.
