Facebook Story Best Practices

Design for Vertical Format

Composition Tips:

  • Vertical orientation - Design specifically for 9:16
  • Leave safe zones - Top and bottom for UI elements
  • Center important content - Avoid extreme edges
  • Mobile-first thinking - Design for phone screens
  • Full-screen impact - Embrace the tall format

Technical Considerations:

  • Top safe zone - Profile picture and account info
  • Bottom safe zone - Interaction buttons
  • Side margins - Keep content slightly inset
  • Mobile preview - Always test on actual device

Content Strategy for Stories

What Works in Facebook Stories:

  • Time-sensitive offers and sales
  • Behind-the-scenes moments
  • Event coverage and updates
  • Product teasers and launches
  • Personal, authentic content
  • Quick tips and tricks
  • Poll and interactive content
  • Day-in-the-life content

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.
