The user needs to prevent PowerPoint from automatically changing or scaling the font size of text pasted from other sources.

How to Stop PowerPoint from Automatically Scaling Pasted Text

Product: Microsoft PowerPoint
Device & OS: Mac and Windows
Scenario: Pasting text from a source document that has different formatting into a PowerPoint slide presentation.
Observed behavior: PowerPoint automatically changes the pasted text size to match source formatting, which overrides the "Do Not AutoFit" setting applied in the slide master.

Before you start

Ensure your presentation is saved and verify that the "Do Not AutoFit" option is enabled in your slide master settings before applying specific pasting methods.

Solution 1Recommended

Use the Keep Text Only Paste Option

The most effective way to strip source formatting and prevent unwanted text scaling is to paste the content as unformatted text.

By choosing to keep text only, PowerPoint ignores the font size, color, and font family of the original document. Instead, it instantly applies the existing font settings of the destination text box on your slide.

Copy the text

Highlight the desired text in your source document or webpage and press Ctrl+C (Windows) or Command+C (Mac) to copy it.

Right-click the destination

Navigate to your PowerPoint slide and right-click inside the text box where you want the text to appear.

Select Keep Text Only

Under Paste Options in the context menu, click the icon that looks like a clipboard with a capital 'A' (Keep Text Only).

Pro Tip: Using this method guarantees the text will adhere to your slide master's 'Do Not AutoFit' constraints.

Solution 2

Paste Unformatted Text via Paste Special

Use the Paste Special dialog box to explicitly select unformatted text from the ribbon menu.

Solution 3

Use the Merge Formatting Option

Use Merge Formatting if you want the text to adapt to the destination size while retaining basic elements like bolding or italics.

Frequently Asked Questions

Can I set 'Keep Text Only' as the universal default in PowerPoint for Mac?

Currently, PowerPoint for Mac does not offer a universal setting to make 'Keep Text Only' or unformatted text the default pasting method across the entire application. You must manually select this option when pasting.

Why does text still resize when 'Do Not AutoFit' is selected?

The 'Do Not AutoFit' setting prevents text boxes from resizing text when it overflows the bounding box. However, pasting text that includes its own source formatting overrides this command, causing the text size to change according to the copied style rather than the slide master.

What is the keyboard shortcut for Paste Special?

On Windows, you can press Ctrl+Alt+V to open the Paste Special dialog box quickly. On a Mac, use Control+Command+V, then select 'Unformatted Text' from the menu.
