The user wants to prevent PowerPoint's Autofit feature from altering the line spacing when it reduces the font size inside a placeholder.

How to Keep PowerPoint Line Spacing Fixed When Autofitting Text
Product
PowerPoint
Device & OS
not provided
Scenario
Formatting text inside a slide or Slide Master placeholder when the text exceeds the placeholder dimensions.
Observed behavior
PowerPoint automatically shrinks both the font size and the line spacing simultaneously, leading to inconsistent text formatting across different slides.
Before you start

Open your presentation and ensure you are working in the Slide Master view (View > Slide Master) if you want these spacing adjustments to apply to all new slides universally.

Solution 1Recommended

Set Line Spacing to 'Exactly' in Points

Changing the line spacing setting from Multiple/Single to Exactly forces PowerPoint to maintain the precise distance between lines, even if the Autofit feature activates and reduces the text size.

By default, PowerPoint uses relative line spacing (like Single or Multiple). When the font shrinks, relative spacing shrinks along with it. Applying an absolute value via the 'Exactly' setting overrides this behavior.

1
Select the placeholder

Click on the border of the text box or placeholder you want to adjust so that the entire block is selected.

2
Open Line Spacing Options

Go to the Home tab on the ribbon, click the Line Spacing icon in the Paragraph group, and select Line Spacing Options from the dropdown menu.

3
Change to Exactly

In the Paragraph dialog box, locate the Spacing section. Change the Line Spacing drop-down from 'Multiple' or 'Single' to 'Exactly'.

4
Enter a point value

In the 'At' box next to it, enter a specific point value (e.g., 24 pt) that corresponds to your desired spacing.

5
Apply changes

Click OK to save. Now, when you add more text to the placeholder, the font size will shrink but the line spacing remains fixed at your specified points.

Set Line Spacing to 'Exactly' in Points
Choosing the Right Point Value: A standard rule of thumb is to set the Exact spacing slightly larger than your default font size (for instance, set spacing to 24 pt for a 20 pt font) to ensure the text remains legible without lines overlapping.

Frequently Asked Questions

Why does PowerPoint change my line spacing when I type too much text?

This happens because the 'Autofit text to placeholder' feature is enabled by default. When the text exceeds the placeholder confines, PowerPoint proportionately shrinks both the font size and the line spacing to squeeze the content into the available space.

How do I turn off Autofit in PowerPoint entirely?

Right-click the placeholder perimeter and select 'Format Shape'. In the pane that appears, navigate to 'Text Options', click the 'Textbox' icon, and select 'Do not Autofit'. This prevents both font size and spacing from shrinking, though overflowing text will spill out of the box.

Does setting 'Exact' line spacing affect different font sizes in the same text box?

Yes. When line spacing is set to Exactly in points, that spacing remains fixed regardless of the font size. This can cause text overlapping issues if you later increase the font size to be significantly larger than the predefined exact point value.
