How to Set a Persistent Default Line Style in PowerPoint
Question details
The user wants to set a global, persistent default line style (including color and weight) for all new PowerPoint presentations.
- Product
- Microsoft PowerPoint
- Device & OS
- Windows
- Scenario
- Creating new presentations and needing a standardized line format without having to manually adjust the color and weight every time.
- Observed behavior
- PowerPoint stores default shape and line formatting per-presentation rather than applying them globally to all newly created presentations.
Decide on your preferred line color, weight, and style before creating the template, as these settings will serve as the baseline for your future presentations.
Create and Save a Custom Default Theme Template
This method allows you to save your custom line settings as a globally accessible template for future presentations by modifying the default theme.
Since PowerPoint applies default line styles on a per-presentation basis, the most effective way to make them persistent is to embed the setting into a custom template and use that template when starting new projects.
Open a blank presentation in PowerPoint. Draw a standard line using the Shapes tool, format its color and weight to your preference, right-click the line, and select 'Set as Default Line'.
Once the default is set, delete the line from the slide so that your template remains empty and clean for new projects.
Click 'File' > 'Save As'. Choose 'PowerPoint Template (*.potx)' or 'PowerPoint Macro-Enabled Template (*.potm)' from the file type dropdown menu.
Name the file 'Default Theme.potx' and save it to the directory '%appdata%\Microsoft\Templates\Document Themes'. You can paste this path directly into the File Explorer address bar.
Restart PowerPoint. When creating a new presentation, select your custom theme from the 'Personal' or 'Custom' templates tab to inherit your saved default line settings.

Use a Pre-formatted Blank Presentation
If the custom theme template does not retain the line settings across sessions, use a saved empty presentation as your startup file.
Use WPS Presentation for Simplified Template Management
WPS Office offers a highly compatible and user-friendly Presentation tool that makes it easy to set default object styles and manage custom templates for all your slides.
- 1. Insert and format a line: Open WPS Presentation, go to the 'Insert' tab, select 'Shapes', and draw a line. Adjust the outline color and weight.
- 2. Set as default: Right-click the formatted line and select 'Set as Default Line'. Delete the line to keep the slide clean.
- 3. Save as a custom template: Click 'Menu' > 'Save As', choose 'WPS Presentation Template (*.dpt)' or 'PowerPoint Template (*.potx)', and save it to your custom templates folder.
- 4. Create from template: Next time you start WPS Presentation, go to the 'New' tab and open your saved template to begin with your persistent line styles.

Frequently Asked Questions
Why does my default line style reset when I open a new PowerPoint file?
PowerPoint saves default shape and line formatting on a per-presentation basis. Unless you save these customized settings into a global template or theme, new files will automatically revert to the software's standard default styles.
Can I apply a default line style to an existing presentation?
Yes. You can draw a line in your current presentation, apply your desired formatting (color, weight, dash type), right-click it, and select 'Set as Default Line'. This applies your preferences to any new lines drawn within that specific file.
Where is the Document Themes folder located in Windows?
By default, you can access the Document Themes folder by pressing Windows Key + R, typing '%appdata%\Microsoft\Templates\Document Themes', and pressing Enter. This folder stores custom themes (.thmx) and templates (.potx).
