PowerPoint Text Box Autofit Keeps Turning Back On: Fix

You set a text box to Do not autofit in PowerPoint, but the next time you open the presentation or add text, the setting reverts to Shrink text on overflow. This behavior occurs because PowerPoint applies autofit settings on a per-presentation and per-shape basis, and some settings are stored in the presentation file itself rather than as a global default. This article explains why the autofit option keeps turning back on and provides three reliable methods to stop it from resetting permanently.

Why PowerPoint Autofit Keeps Turning Back On

PowerPoint’s autofit feature is designed to automatically resize text within a shape when the text exceeds the shape’s boundaries. The setting Shrink text on overflow is enabled by default for all new text boxes created from the Insert > Text Box command. When you manually change a text box to Do not autofit, the change applies only to that specific shape instance. PowerPoint does not save this preference as a global default. The next time you create a new text box or open a different presentation, the default autofit behavior reasserts itself.

Additionally, some presentation templates or slide masters contain preconfigured autofit settings. If a slide master has autofit enabled for placeholder text boxes, any text box derived from that master will inherit the autofit behavior regardless of local changes. This is why the setting appears to “turn back on” — the master setting overrides the individual shape setting when the presentation is reopened or when the shape is recreated.

Three Methods to Permanently Disable Text Box Autofit

Use the method that matches your workflow. Method 1 disables autofit for a single text box. Method 2 sets a default for all new text boxes in the current presentation. Method 3 changes the slide master to control autofit across the entire presentation template.

Method 1: Disable Autofit for a Specific Text Box

1. Select the text box
   Click the border of the text box to select the entire shape, not just the text cursor.
2. Open Format Shape pane
   Right-click the text box border and choose Format Shape. Alternatively, go to the Shape Format tab and click Format Pane.
3. Go to Text Options > Text Box
   In the Format Shape pane, click the Text Options tab (the icon with an A and lines). Then click the Text Box icon (a box with text lines inside).
4. Select Do not autofit
   Under the Autofit section, choose Do not autofit. The text box will now keep its size regardless of text length.
5. Close the Format Shape pane
   Changes are applied immediately. Save the presentation to preserve the setting for this text box.

Method 2: Set Do Not Autofit as the Default for New Text Boxes

1. Format a sample text box
   Create a text box and apply Do not autofit using Method 1 steps 1 through 4.
2. Right-click the text box border
   Make sure you click the border, not the text inside. A context menu appears.
3. Choose Set as Default Text Box
   Click Set as Default Text Box from the context menu. All future text boxes inserted in this presentation will use Do not autofit.
4. Test the default
   Insert a new text box from Insert > Text Box. Type a long sentence. The text box should not resize or shrink text.

Note: This default applies only to the current presentation. Other presentations will still use PowerPoint’s default autofit setting.

Method 3: Change Autofit in the Slide Master

1. Open Slide Master view
   Go to View > Slide Master. The Slide Master tab appears.
2. Select the topmost slide master
   In the left thumbnail pane, click the first and largest thumbnail. This master controls all layouts below it.
3. Select a text placeholder
   Click the border of a text placeholder, such as the title or body text area.
4. Open Format Shape pane
   Right-click the placeholder border and choose Format Shape.
5. Set Do not autofit
   In the Format Shape pane, go to Text Options > Text Box and select Do not autofit.
6. Repeat for other placeholders
   If your presentation uses multiple text placeholders, repeat steps 3 through 5 for each one.
7. Close Slide Master view
   Click Close Master View on the Slide Master tab. All slides based on this master will now use Do not autofit.

If Autofit Still Turns Back On After the Fix

Autofit resets after saving and reopening the presentation

This usually happens when the presentation uses a custom template that has autofit enabled in the slide master. Open the presentation again, go to View > Slide Master, and check each layout for autofit settings. Change all text placeholders to Do not autofit. Save the presentation as a .potx template file if you want to reuse the setting in new presentations.

Autofit turns back on when you paste text from another source

Pasting text from Word, a web page, or another presentation can bring formatting that triggers autofit. After pasting, click the Paste Options button that appears at the bottom-right of the pasted text and choose Keep Text Only. Then apply Do not autofit to the text box again.

Autofit re-enables when you resize the text box manually

PowerPoint sometimes resets autofit to Shrink text on overflow when you drag a text box handle to resize it. After resizing, immediately right-click the text box border, open Format Shape, and verify that Do not autofit is still selected. If it changed, reapply the setting.

Comparison of Autofit Disable Methods

Item	Single Text Box	Default for Presentation	Slide Master
Scope	One text box only	All new text boxes in current presentation	All text placeholders in the template
Persistence	Lasts until manually changed	Lost when presentation is closed	Saved with the template
Steps required	5 steps	4 steps	7 steps
Best for	One-off text boxes	Repeated text box insertion in one file	Company-wide or recurring presentations

You can now disable autofit permanently for any text box using the Format Shape pane, set a default for the current presentation, or modify the slide master for template-wide control. If autofit continues to reset, check the slide master settings first. Use the Set as Default Text Box command each time you start a new presentation to avoid the problem repeating.
