Can I Change the Font Size of Captions in the Video Editor?

Yes — captions in the Video Editor are fully customizable, including font size. Once captions are added to a clip, you can resize them in the Typography panel of the right-hand inspector.

Steps

1. Open your video in the Video Editor

Open the video project that has captions (or generate captions on a clip with audio if you haven't yet — see Generate captions in the Audio section of the Video inspector).

2. Select the captions layer

Click the captions layer on the timeline (or click the captions text on the canvas). The right-hand inspector switches to Captions controls.

3. Adjust the font size

In the inspector, find the Typography section. Inside it, use the Font size control to set a new size — type a number directly into the input or use the up/down arrows to step through values.

The captions on the canvas update live as you change the size.

4. Fine-tune the rest of the look (optional)

While you're in the Typography section, you can also adjust:

Font family — pick a different typeface
Font style — bold, italic, regular, etc.
Line height and Letter spacing — for breathing room between lines and letters
Alignment — left, center, right

And in the other sections nearby:

Layout — position, size, rotation of the captions box
Fill — text color, highlight color, opacity
Stroke — outline width and color
Captions — switch the Style preset, change page duration, set max lines

5. Preview and save

Press play under the canvas to confirm the new size reads well at full speed. Your changes save to the video project automatically — there's nothing extra to click.

How do I know it worked?

You'll know the font size change is applied when:

The captions on the canvas appear at the new size during playback.
The Font size field in the Typography panel shows your chosen value.
When you export the video, the rendered file uses the new size.

Tips

Match size to aspect ratio. Larger sizes (e.g. 80–120) read well on 9:16 vertical videos for TikTok, Reels, and Shorts. Smaller sizes work better for 16:9 widescreen.
Use Style presets first, then tweak. Picking a preset in the Captions → Style section sets typography, color, and stroke as a package — change the size on top to fine-tune.
Pair size with Max lines. If captions wrap awkwardly, increase Max lines in the Captions section, or reduce font size slightly so each phrase fits.
Add a stroke for readability. A small white or black stroke (in the Stroke section) keeps captions readable over busy backgrounds at any size.

Troubleshooting

I don't see a Typography section in the inspector. Make sure the captions layer is selected (not the video clip itself). Click the captions on the canvas or the captions row on the timeline, then look at the right-hand inspector again.

My video doesn't have a captions layer yet. Select the video clip, scroll the right-hand inspector to the Audio section, and use the Generate captions option to create them. Then come back to this article and adjust the font size from step 2.

Captions look fine in preview but the exported file is different. Export again after making changes — old exports keep the previous size. The latest font size only ships with the next render.

I can't type a number into the Font size field. Click directly inside the input first, or use the up/down arrows. If it still won't accept input, click somewhere else on the canvas to deselect, then reselect the captions layer.

I changed the size but it reverted. That can happen if you switch between captions Style presets after editing — the preset re-applies its built-in size. Set the size after picking the preset, and your value will stick.

Next step

Your captions are resized and saved to the video project. When you're ready to share, click Export in the top action row to render a new video file with the updated captions.
