Hi,

Presently CapCut for PC does not include a built‐in option to enlarge the text size of the captions editing interface itself. While you can easily adjust the font size, style, and layout of the captions that appear in your final video, the editing tool’s UI (the text input area where you edit your captions) remains fixed in size.

However, you can try these workarounds:

• System display scaling: Increasing your Windows display or DPI scaling settings will enlarge all interface elements, including CapCut’s, though this affects everything on your screen.
• Adjusting the font size: While you can't directly make the caption editing box bigger, you can change the font size of the captions themselves. Select the caption text you want to adjust. In the text editing panel, you'll find options to change the font, style, and size. Increase the font size to make the captions more visible.
• Magnifier Tool: Using Windows’ built-in Magnifier can help you zoom in on the specific area of the screen while you work.
• Using a larger font: Choose a font that is naturally larger and easier to read. Some fonts tend to appear bigger even at the same font size compared to others.
• Previewing at full screen: When you're working on your captions, you can preview your video in full-screen mode. This will give you a better view of how the captions will look on the final video and help you determine if the size is appropriate.
• If you're still unsure about the caption size, you can export a short section of your video with the captions and check it on a larger screen. This will give you the most accurate representation of how the captions will appear to your audience.

CapCut's PC version has some limitations when it comes to caption customization compared to the mobile version.

Many users have noticed this limitation and have requested a feature update, so this is something will most likely be updated in future releases. For now, adjusting your system settings is your best bet.
