- Bold, high-contrast subtitles with a dark outline work best on mobile - thin fonts disappear on small screens.
- The viral TikTok style uses bold white text with a black outline and word-by-word highlight animation.
- Keep subtitle text large enough to read on mobile - at least 5% of video height.
- Use a semi-transparent background box if the video has busy backgrounds that make text hard to read.
