Creator Use Cases
Use Stories for day-to-day audience engagement — polls, Q&As, and behind-the-scenes content that builds community.
Use Reels for high-reach content that can go viral and attract new followers — tutorials, trends, and entertainment.
Cross-promote Reels in Stories to give your Reels content additional exposure to your existing audience.
Save important Stories as Highlights so they become permanent reference content on your profile.
Test content ideas in Stories first (low effort), then produce the winning concepts as polished Reels.

Workflow Guidance
Film all vertical content at 1080×1920 (9:16) — both formats share the same dimensions and safe zones.
Keep critical content (text, faces, CTAs) in the center 70% of the frame for both Stories and Reels.
For Stories, design with the top 15% (profile/status bar) and bottom 15% (reply bar/caption) as off-limits.
Repurpose Reels content into Stories by trimming clips — get more mileage from your best footage.
Save Story templates in your design tool at 1080×1920 for quick daily creation.
