Free Caption Safe-Zone Preview
Place sample caption text inside a 9:16 frame and check its clearance from typical top, bottom, and right-side platform interface areas.
Planning overlay only. Verify the final post on real devices because app chrome changes by account, locale, and version.

What the browser changes
The overlay is a planning approximation based on common interface regions. Platform UI changes by device, account state, locale, post type, and application version.
- Choose a default caption Y position for vertical exports.
- Compare one-line and two-line caption blocks.
- Brief an editor or motion designer before rendering a full batch.
- This is not a pixel-perfect screenshot of every app version.
- Captions can still collide with stickers, usernames, descriptions, and accessibility settings.
- Always test the final post on target devices and accounts.
Quick answers
Are these official platform templates?
No. They are practical planning overlays, not official or guaranteed interface specifications.
Do I need to upload my video?
No. Use representative text in the preview, then verify the final export separately.
Why does the safe area vary?
Platforms change UI by device, locale, account, and post type, so no single overlay covers every viewer.
