When you type text within PowerPoint, the appearance of your text, such as its font type and size is based on the
Theme which is applied to your presentation. So if you use PowerPoint's default
Office Theme, then anything you type into a text object may be in the Calibri typeface. You can
easily change the Theme Fonts set altogether for
your presentation, and all text instances will change to the default typefaces of the new Theme or Theme Fonts set. However, there
may be times when you want to override these defaults and choose a typeface that is different, or even a different font size. In
this tutorial, we use the terms typeface and font type interchangeably. Let us now explore how you can choose different font types
and change the font size of the selected text on
the slide in PowerPoint 2013 for Windows:
- Create a new presentation and type some text in the placeholder, as shown in Figure 1.

Figure 1: Text on the slide
- Select the text which you want to format (refer
to Figure 1, above). Now, navigate to the Home tab of the
Ribbon and locate the Font group, as shown
highlighted in red within Figure 2.

- Within the Font group, click the down-arrow located next to Font option, as shown
highlighted in red within Figure 3. This brings up the Font
drop-down gallery, as shown in Figure 3.

As you can see in Figure 3, above the Font drop-down gallery is divided into two sections:
-
Theme Fonts, highlighted in blue, within
Figure 3 above, displays the active font types of your presentation.
-
All Fonts - displays all fonts installed on the system, highlighted in
green within Figure 3, above.
- To change the font type from the default Theme Fonts to some other font, first select the text. Thereafter, open the
Font drop-down gallery shown in Figure 3, scroll down and choose any font type from within the
All Fonts section. As you hover your cursor over any of the font types you'll see a
Live Preview of fonts changing on the active slide.
Figure 4 below shows a different font type, Arial being selected, and also a live preview of this
font type on the selected text can be seen within the Slide
Area. Compare the slides shown in Figures 4 and 1. Click on the font type (as opposed to
hovering over it) within the drop-down gallery to apply it to the selected text.

Alternatively, you can directly type the name of the font within the Font box, as shown in
Figure 5. Start typing the first few alphabets of the font you want to use. For example, when we typed
Ari, we could locate Arial. Once the font name is active (see Figure 5), press
the Enter key to apply the font type to the selected text.

- With the text still selected, navigate to the Home tab of the
Ribbon and within the Font group click the
down-arrow located next to Font Size option, as shown highlighted in red within
Figure 6. This brings up the Font Size drop-down gallery, as shown in
Figure 6.

- Note that the highlighted font size is the size of the currently selected text. Now, scroll down the Font Size
gallery to select other font size. As you hover your cursor over any of the font size, you'll see a
Live Preview of the changed font size of the selected text
on the slide, as shown in Figure 7 (compare it with Figure 4, shown earlier on this age). Also
you can directly type in the font size value within the Font Size box.

Alternatively, you can also use the Increase Font Size and Decrease Font Size buttons,
highlighted in red within Figure 7 above to change the font size of selected text.
- Selecting the text (or alternatively right-clicking some selected text) brings up the
Mini Toolbar which includes the same options
(highlighted in red within Figure 8) as within Font group of
Home tab of the Ribbon, to change the font type and font size of the selected text.
