Hi @Dakota Clark
Thank you for your prompt response.
Please note that this feature is typically available in the desktop version of PowerPoint, so if you're using PowerPoint for the web or a simplified version, the Slide Master may not be accessible.
To help you update your default font, here are a couple of alternative methods you can try:
1.Check Your PowerPoint Version
Some simplified or web-based versions of PowerPoint (like PowerPoint for the web or mobile) don’t include the Slide Master feature. Make sure you're using the desktop version of PowerPoint.
2.Use the “Design” Tab Instead
If Slide Master is unavailable, you can try this workaround:
- Go to the Design tab.
- Click Variants (on the right side).
- Choose Fonts > Customize Fonts.

- Set your Heading and Body fonts.
- Name your font set and click Save.

This will apply the font to the current presentation, but not globally.
3.Change the Default Font for All New Presentations
To make a font the default for all future presentations:
- Open a blank presentation.
- Apply your preferred font using the steps above.
- Save the file as a PowerPoint Template (.potx):
- File > Save As > Browse
- Choose PowerPoint Template (.potx)
- Save it in this folder:
C:\Users<YourName>\Documents\Custom Office Templates
When creating new presentations, select this template via:
- File > New > Choose your custom template for future presentations.

4.Use Keyboard Shortcut to Access Slide Master (if available)
- At the Home tab, try pressing: Alt + W + M
- This is the shortcut for View > Slide Master.

- The Slide Master tab appears between the File tab and the Home tab. If nothing happens, it confirms the feature isn’t available in your version.
