How to set default fonts and colours in PowerPoint so every new file is on brand
Create a custom theme with your brand fonts and colours, then save it as the default theme. Go to View > Slide Master, set your theme fonts (Fonts > Customise Fonts) and theme colours (Colours > Customise Colours), close the slide master, then go to the Design tab and click the dropdown arrow in the Themes group. Select "Save Current Theme" and save it to PowerPoint's default Document Themes folder. Every new blank presentation will use your brand settings from that point forward.
How do you set default fonts?
In the slide master view, click Fonts on the Slide Master ribbon and select Customise Fonts. Assign your brand's heading typeface to the Heading slot and your body typeface to the Body slot. Name the font theme with your organisation's name. These fonts become the default for every placeholder, text box and title across the template.
If you want these fonts to persist as the default for all new presentations (not just those created from a specific template), save the theme to the Document Themes folder as described above. PowerPoint uses the most recently saved theme as the default when you create a blank presentation.
How do you set default colours?
In the slide master view, click Colours > Customise Colours. Enter your brand's HEX or RGB values into each of the 12 theme colour slots. Map your primary brand colour to Accent 1, your secondary colour to Accent 2, and fill the remaining slots with supporting palette colours. Name the colour theme with your organisation's name.
These colours populate the colour picker across the entire application. When staff choose a font colour, shape fill or chart series, your brand colours appear as the default options in the top row of the picker. This single setup step eliminates the majority of off-brand colour choices.
How do you save the theme as the default?
Close the slide master and return to Normal view. On the Design tab, click the dropdown arrow at the bottom-right of the Themes group. Select "Save Current Theme". PowerPoint opens the Document Themes folder automatically. Save the theme file (.thmx) with a descriptive name. To make it the true default for blank presentations, save a .potx template with this theme applied to the default template location (File > Options > Save > Default personal templates location).
On Windows, you can also replace the default blank presentation template. Save your themed file as "Blank.potx" in the C:\Program Files\Microsoft Office\root\Document Themes folder (the exact path varies by Office version and installation type). This requires administrator access and affects every user on that machine.
Does this affect Word and Excel too?
Theme files (.thmx) are shared across Office applications. If you save a .thmx theme and apply it in Word or Excel, the same fonts and colours become available. However, each application has its own default template, so saving a theme in PowerPoint does not automatically change the defaults in Word or Excel. You need to create and distribute default templates for each application separately.
At Ideaseed, we build theme files as part of every Microsoft Office template suite we deliver. The .thmx file ensures that PowerPoint, Word and Excel all share the same colour palette and font settings, even though each application needs its own template for layout and structural elements.
What if staff override the defaults?
Staff can still choose any font or colour from the full picker. Theme defaults do not lock staff out of other options. They make the on-brand choice the easiest choice. If your brand's heading font appears at the top of the font list and your brand colours appear in the first row of the colour picker, most staff will use them out of convenience.
If you need stricter control, combine theme defaults with a well-built slide master (so layout elements are locked) and staff training (so people understand why brand consistency matters). No single technical setting replaces good training.
How do you deploy defaults across a team?
For small teams, share the .thmx file and ask staff to save it to their Document Themes folder. For enterprise rollouts, use Group Policy to set the default template location to a network share or SharePoint library containing your branded templates. This ensures every user starts from the same defaults without manual configuration.
Setting default fonts and colours takes a few minutes and shapes every presentation your team creates from that point on. Build the theme, save it as a .thmx and a .potx, and distribute both to your team.
If you need a consistent set of defaults across PowerPoint, Word and Excel, Ideaseed can build a complete template suite for your organisation.
