Dashed zones are common interface-risk areas, not official templates.

under the hood

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.

common use cases

  • 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.

limitations to check

  • 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.

frequently asked questions

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.
