Turn Off AutoFit in PowerPoint (Stop Text Shrinking)

AutoFit is the PowerPoint feature that quietly shrinks your text when a placeholder starts to overflow. Add two bullets and the whole list drops from 20 pt to 16 pt, with tighter line spacing to match. To turn off AutoFit in PowerPoint, you choose Do not Autofit in Format Shape (or Stop Fitting Text from the AutoFit Options button), and to do it for a whole deck you change it on the slide master. In a training deck that several people keep adding to, leaving AutoFit on is how body text ends up at 24 pt on one slide and 13 pt on the next, unreadable from the back of the room.

What AutoFit does and where it applies

Microsoft's guide to AutoFit options explains that the AutoFit Options button appears at the lower-left corner of a placeholder only when it starts to overflow, and that shrinking the text to fit is the default for placeholders. The button appears only on placeholders, not on text boxes you draw yourself.

That distinction explains most of the confusion. Placeholders are the dotted boxes a layout puts on the slide ("Click to add title," "Click to add text"). Text boxes drawn with Insert > Text Box default to growing the box to fit the text instead, so they spill off the bottom of the slide rather than shrinking.

To check whether a slide has been shrunk, select the body text and look at the font size box on the Home tab. If it reads smaller than the layout's body size (typically 18 to 24 pt) and nobody set it that way, AutoFit did.

There are three settings:

How to turn off AutoFit

Turn off AutoFit for one placeholder

When a placeholder overflows, click the AutoFit Options button at its lower-left corner and choose Stop Fitting Text to This Placeholder. Choose AutoFit Text to Placeholder from the same menu to turn it back on.

If the button isn't showing, use Format Shape:

1. Click the placeholder's border so the whole box is selected.
2. Click the dialog launcher in the corner of the Drawing group on the Home tab, or right-click and choose Format Shape.
3. In the pane, select Text Options, then the Text Box icon.
4. Choose Do not Autofit.
5. Text that already shrank does not grow back. Select it and set the size you want.

Turn off AutoFit for the whole deck

On a 20-slide deck, doing this one placeholder at a time means 40 rounds. Change it once on the master:

1. On the View tab, select Slide Master.
2. Select the master at the top of the pane. Select its title placeholder, set Do not Autofit in Format Shape, then do the same for the body placeholder.
3. Check any layout whose placeholders have their own settings and change those too.
4. Select Close Master View.

Slides that were already adjusted by hand may keep their old setting. Select them and click Reset in the Slides group on the Home tab to bring placeholders back to the layout, or reapply the same layout from Home > Layout, as Microsoft's guide to reapplying a layout describes.

Turn off AutoFit for all new files

To stop AutoFit in every placeholder you create from now on, go to File > Options > Proofing > AutoCorrect Options, open the AutoFormat As You Type tab, and clear AutoFit title text to placeholder and AutoFit body text to placeholder. This is a setting for your copy of PowerPoint, so it does not change existing files, and each person on the team has to set it on their own computer.

Three ways to handle the overflow

Once AutoFit is off, overflowing text spills past the placeholder. That is the signal to edit, not shrink. The rest of the AutoFit Options menu helps:

Split Text Between Two Slides. PowerPoint creates a new slide with the same title right after the current one and divides the text roughly in half.

Continue on a New Slide. Leaves the text where it is and creates a new slide with the same title for you to keep typing.

Change to Two Columns. Formats the existing text in two columns, good for long lists of short items. Switching the slide to a Two Content layout from Home > Layout does much the same.

These options work only on placeholder body text. For a drawn text box, cut the extra text and paste it onto another slide.

A worked example: a distributor training deck

Ridgeline Manufacturing's sales support team is cleaning up a 22-slide product training deck for next month's distributor sessions with Lakeview Distribution. Three product managers have been adding specs and installation notes all year. Body text ranges from 20 pt to 13 pt, and the training room holds 40 people, so nothing below 18 pt is acceptable.

In Slide Sorter, the coordinator flags the crowded slides, then checks the font size box on each one. Seven of the 22 are below 18 pt. None of the product managers remembers shrinking anything; AutoFit had been trimming the text a little each time they added a line.

She turns AutoFit off for the title and body placeholders on the slide master, sets body text to 20 pt, and closes Master View. Reset brings four of the seven back to 20 pt, but now the text overflows on those four.

Each gets a different fix. Two slides mix specs and installation notes, so she uses Split Text Between Two Slides and adds "(1 of 2)" and "(2 of 2)" to the titles. One slide is a 12-line checklist of short items, so she switches it to Two Content. The last one repeats an explanation from the previous slide, so she cuts the duplicate. The deck grows from 22 to 24 slides, and every body slide is now 20 pt.

Finally, she checks that titles don't jump between slides. If a title placeholder's vertical alignment is set to Middle, one-line and two-line titles sit at different heights, so she sets them all to Top from Home > Align Text.

When to leave AutoFit on

AutoFit has its place. For an announcements slide whose length changes every week, or notes typed live during a meeting, shrinking is convenient. It has no lower limit, though, and reduces line spacing along with font size. For anything presented to a room, treat a body size below 18 pt as the point to split the slide.

When text keeps shrinking anyway

Only the title was changed. Title and body placeholders have separate settings. Check both on the master.

Pasted slides behave differently. Slides pasted with Keep Source Formatting carry their original settings. Choose Use Destination Theme when pasting, or click Reset.

One layout overrides the master. If a layout's placeholder still has AutoFit on, every slide using it keeps shrinking. Check each layout in Slide Master view.

Line spacing still looks tight. AutoFit reduces line spacing too. After turning it off, reset Line Spacing in the Paragraph group to match the other slides.

Version differences

AutoFit settings and Split Text Between Two Slides work the same way in PowerPoint for Microsoft 365, PowerPoint 2019 through 2024, and PowerPoint for Mac. Microsoft notes that PowerPoint for the web does not split text between slides automatically; cut and paste the overflow or use the desktop app.

FAQ

Q. I turned off AutoFit but the text is still small.

Turning it off stops future shrinking; it does not restore the original size. Select the text and set the size, or set it on the master and click Reset.

Q. Why don't I see the AutoFit Options button on my text box?

The button appears only on placeholders. For drawn text boxes, use Format Shape > Text Options > Text Box and pick a setting there.

Q. Does AutoFit affect tables?

No. Table cells don't shrink text; rows get taller instead. If a table runs off the slide, split its rows across two slides.

How inline AI keeps text sizes consistent

inline AI scans the deck you have open, finds every slide AutoFit has shrunk, turns it off on the master, sets one body size, and then splits or tightens each overflowing slide by topic. For manufacturers updating training decks and customer proposals all year, inline AI also keeps the specs, stock levels and prices inside those slides current.
