Device & OS: not provided
Scenario: Creating new text boxes in a presentation and wanting them to automatically use a specific line spacing.

Solution 1Recommended

Configure a Default Text Box and Save as a Custom Theme

This method ensures that any new text box created in future presentations uses your preferred line spacing by modifying the default template.

PowerPoint determines the formatting of newly inserted shapes and text boxes based on the presentation's default theme settings. To permanently change this, you must set a new default text box and save the entire presentation as your default template or theme.

Insert a new text box

Navigate to the 'Insert' tab on the ribbon, select 'Text Box', and click anywhere on the slide to create it.

Adjust the line spacing

Type sample text into the text box. Highlight the text, go to the 'Home' tab, click the 'Line Spacing' icon in the Paragraph group, and set your desired spacing (e.g., 1.5 lines).

Set as Default Text Box

Right-click the outer border of the text box and select 'Set as Default Text Box' from the context menu.

Save as a custom theme or template

Click 'File' > 'Save As' and select 'Browse'. In the 'Save as type' dropdown, choose either 'Office Theme (*.thmx)' or 'PowerPoint Template (*.potx)'.

Name and save the file

Name the file 'Default Theme'. Ensure it is saved in your 'Document Themes' or 'Custom Office Templates' folder, then click 'Save'. You can now select this template when creating new presentations.

Configure a Default Text Box and Save as a Custom Theme

Testing Your New Settings: Restart PowerPoint and create a new presentation using the 'Default Theme' you just saved to verify that new text boxes maintain your custom line spacing.

Frequently Asked Questions

Why does my PowerPoint text box keep reverting to single line spacing?

By default, PowerPoint uses the built-in theme settings for new text boxes. Even if you change the spacing in one text box, new ones will revert to the base theme settings unless you explicitly set your custom text box as the default and save the presentation as a new template.

What is the difference between saving as a .potx and a .thmx file?

A .potx file is a PowerPoint Template that saves specific slide layouts, placeholder text, backgrounds, and default text box settings. A .thmx file is an Office Theme that saves colors, fonts, and effects, which can be applied across multiple Office applications like Word and Excel.

Where should I save my custom PowerPoint template to find it easily?

Custom templates should be saved in the 'Custom Office Templates' or 'Document Themes' folder inside your Documents directory. This ensures they automatically appear in the 'Personal' or 'Custom' tab when you launch PowerPoint to create a new presentation.
