While vertical video dominates Reels and Shorts, square (1:1) video remains the optimal format for certain placements — Facebook feed posts, Instagram feed posts, and LinkedIn feed videos. Understanding when to use square versus vertical gives your business a format advantage that most competitors overlook.

When square video outperforms vertical
Square video (1:1 aspect ratio) occupies 78% more screen space than horizontal video in Facebook and Instagram feeds, while being more versatile than vertical video for certain placements. There are specific situations where square is the better choice:
Facebook News Feed posts.
While Facebook Reels are vertical, standard feed video posts perform best in square format because the feed layout gives square videos more visual real estate than vertical videos outside the Reels tab.
Instagram feed posts.
Instagram feed videos (not Reels) display square and slightly vertical (4:5) formats most prominently. If you are posting to the feed rather than Reels, square format fills more space.
LinkedIn feed videos.
LinkedIn's desktop-heavy audience often views content on horizontal screens. Square video is a compromise that works well on both desktop and mobile.
Email marketing.
Square video thumbnails and GIFs display consistently across email clients where vertical video gets cropped or letterboxed.
Using FluxNote reels for square video placements
FluxNote generates reels in vertical 1080x1920 format, which is optimized for Reels, Shorts, and TikTok. For square feed placements, you have several options:
Crop the vertical output to square.
Use any basic video editor to crop the center section of your vertical reel to 1080x1080. The center-weighted text and animation design means the core message remains intact after cropping.
Create vertical for Reels, square for feed.
The most effective strategy is distributing vertical animated reels to Reels/Shorts/TikTok while creating separate square-optimized content for feed posts. This ensures each placement gets the ideal format.
Prioritize vertical for most use cases.
In 2026, vertical video is the dominant format across all major platforms. Square video is best reserved for specific feed placements and email marketing where vertical does not display optimally.
The key insight is that format choice should follow placement. Where is your video going to appear? Match the format to the placement for maximum visual impact.
Square video strategy for business advertising
Square video excels in specific advertising contexts:
Facebook feed ads.
Square video ads in the Facebook News Feed get higher click-through rates than horizontal video ads because they occupy more screen space. For businesses running feed-based ad campaigns (not Reels ads), square is the optimal format.
Instagram carousel ads.
Video slides within Instagram carousel ads display best in square or 4:5 format. Animated business content as carousel slides creates an interactive, multi-scene ad experience.
Retargeting campaigns.
Square video retargeting ads in Facebook and Instagram feeds are effective because they appear where users expect standard content, reducing ad blindness compared to obviously-formatted ad placements.
A/B test formats.
Run the same business reel in both vertical (for Reels placement) and square (for feed placement) to see which format drives better results for your specific audience. The data will guide your format strategy going forward.
