Frequently asked questions
What are safe zones in vertical video?
The regions platform UI doesn't cover. TikTok's right rail eats roughly the right 15% (like/comment/share stack); the bottom ~20% carries captions and sounds; Reels and Shorts differ in the details. Anything essential — faces, text, hooks — belongs inside the remaining middle.
Are these overlays exact?
Close, not gospel: platforms A/B-test their UI constantly and phone aspect ratios vary. The overlays here follow the commonly published guidance and get refreshed in one JSON file — treat them as a strong draft, and keep truly critical text well inside.
What size should my video be?
1080×1920 (9:16) is the native vertical canvas everywhere. The previewer letterboxes anything else so you can still judge coverage.
Can I check a video, not just a frame?
Grab a screenshot of the busiest moment (usually where text appears) and check that — coverage doesn't move during playback, so one representative frame tells the story.
