How does the Facebook Reels safe overlay work?
Facebook Reels ads appear between organic Reels in the dedicated Reels tab or within the main Facebook feed. The UI for Reels is significantly more complex than Stories, featuring a right-side engagement rail and a dense bottom info section that includes the profile, caption, and audio attribution.
FB Reels safe-overlay best practices
- The Right-Side Engagement Rail: Unlike Stories, Reels have a persistent set of icons on the right (Like, Comment, Share). You must leave at least 80px of margin on the right edge to prevent your content from being obscured.
- Top 130px for Navigation: The top of the screen contains the "Reels" label and search/menu icons. Keep this area clear to maintain a professional look.
- The Bottom 240px "Power Zone": This is where the profile name, "Sponsored" label, caption, and CTA reside. Any critical text or logos placed here will be completely unreadable.
Visual Hierarchy: Capturing Attention in a Feed
Reels are a "lean-in" experience where users actively swipe for new content. Your ad must compete for attention:
- The Center Focus: Place your primary subject in the central "Safe Overlay." Avoid placing important elements on the right half of the screen where they might clash with the engagement rail.
- Caption Clearance: Remember that captions can be 1-2 lines long by default. Our overlay shows the "expanded" safe overlay to ensure your message gets through even if the user is reading the caption.
- Dynamic Bottom: The "Sponsored" CTA pill is dynamic and can vary in color based on the ad creative. Ensure your bottom-most visible content has enough contrast to remain distinct from the CTA.
Optimizing for the "Right-Side Rail"
The right 80px of a Facebook Reels ad is a high-interaction zone.
- No Text on Right: Never place headlines or small text on the right side. It will be shredded by the "Like" and "Comment" icons.
- Vertical Balance: Because so much UI is on the right and bottom, try to balance your visual weight on the left and upper-middle sections of the screen.

How does FB Reels UI differ from Instagram Reels? While the layout is similar, Facebook's bottom navigation bar and top header have different dimensions and icon placements. Our tool uses Facebook-specific metrics to ensure your ad doesn't look like a direct port from Instagram that ignores Facebook's unique UI.
