This guide simulates the 1080×1920 Stories/Reels frame and shades exactly where Facebook overlays its own interface, so you can confirm your headlines, logos and faces sit in the safe central zone rather than hiding behind a button or caption.
How it works
Facebook reserves fixed strips of the vertical frame for UI: the top holds the profile chip and close button, and the bottom holds the caption, audio attribution and action buttons. The tool models these as percentage margins of the 1080×1920 canvas — roughly the top 13% and bottom 18% for Stories, with Reels reserving a little more at the bottom.
The simulator draws the full frame, shades the dead zones, and outlines the green safe area in the centre. Anything you place inside that green box is guaranteed visible across devices; anything in the shaded bands risks being covered.
Tips
- Centre your key message vertically — the exact middle of the frame is always safe.
- Leave the bottom strip clear on Reels, where the caption and music label can expand to two lines.
- When in doubt, keep a 14% margin on all four edges; it is the most reliable cross-device safe zone.
