Safe Zone Checker
Upload a finished post, cover, or ad image and check it against Facebook's UI overlay zones.
Anything in the dimmed area risks being covered by platform UI (titles, captions, buttons, rounded corners). Keep key subjects and text inside the dashed line.
UI-overlay formats
Feed, Stories, and Reels each carry their own overlay risk in the actual app — a plain feed image has almost none, while Stories and Reels stack reply bars, sticker shortcuts, and action buttons directly over the top and bottom of the frame.
Cover formats
Page cover, Event cover, and Group cover look similar at a glance but each has its own separate crop and overlap rules — three formats that are easy to mistake for one generic "cover" safe zone when they're really not interchangeable.
Six formats in total, each worth checking under its own exact label rather than assuming a result from one covers the rest.
