Common Facebook Story Mistakes
Using Horizontal Images
Horizontal images in vertical format create large letterbox bars that waste screen space and look unprofessional.
Ignoring Safe Zones
Content placed at extreme top or bottom gets covered by Facebook's UI elements like your profile picture and interaction buttons.
Text Too Small
Text must be large enough to read on mobile devices. What looks fine on desktop may be illegible in stories.
Not Optimizing for Mobile
Stories are viewed almost exclusively on mobile. Desktop preview doesn't reflect actual viewing experience.
