Safe zones for captions in vertical video

Short answer

A safe zone is the part of a vertical frame that platform buttons, names and captions do not cover. Keep captions and key text well inside it, away from the bottom and right edges where interface elements usually sit. Layouts differ by platform and change, so test on a real phone before posting.

Why do safe zones matter?

Interface elements overlay your video, and text under them is hard to read. A caption placed too low can be hidden by the post text or buttons.

How do you build a safe margin?

Keep key text toward the middle of the frame
Leave generous space at the bottom and on the right
Test a draft by uploading as private or previewing on a phone
Keep the same margin across all platforms

We do not give exact pixel margins because platforms change their layouts. Test on a real device.

How do skills handle it?

Explainer places captions under your chin on a dark pill, and Bold uses a dark plate. Check the stills on your phone before you render.

Frequently asked questions

Is the safe zone the same everywhere?

No. Layouts differ and change.

Where do buttons sit?

Commonly along the right side and bottom, but check each app.

How do I test?

Preview a draft on a real phone in the target app, check that nothing is covered by buttons or text, then adjust your margins.

Can I use the same margin for all platforms?

A cautious margin works for most.

Do captions need a background?

A plate helps contrast.
