What's the best all-around caption font?

Arial Black. It's thick, readable on any background, available on every platform, and works with every caption style. If you only learn one font for captions, make it this one.

Can I use custom fonts in my video captions?

It depends on the tool. Most video editors support system fonts. Tools like [Dubcap](https://dubcap.app) offer 13+ font options including Roboto, Poppins, Lato, Bebas Neue, Georgia, and Impact — covering every content type without needing to install anything.

Should I use uppercase or lowercase captions?

Uppercase works for short, punchy phrases (3-4 words per group). Lowercase is better for longer text and conversational content. Most podcast and interview content reads better in uppercase with word-by-word highlighting. Editorial content reads better in mixed case.

Does font choice affect watch time?

Yes. Unreadable captions cause viewers to scroll away in the first 1-2 seconds. A/B tests consistently show that switching from a thin, hard-to-read font to a bold sans-serif like Arial Black or Roboto Bold improves average watch time by 10-20%.

What font weight should I use?

Bold (700) at minimum for captions. Extra Bold (800) or Black (900) is better. Regular weight only works if your caption style includes a solid background box. Never use Light or Thin weights for captions. --- *Want to try different caption fonts on your own clips?
