New Instagram Feed Ratio Guide for Post Optimization
Instagram has updated its visual display rules, introducing a new Instagram feed ratio that influences how images, videos, and ads appear in the feed. This shift impacts engagement, visibility, and the aesthetic appeal of posts. For marketers, creatives, and casual users alike, learning how to adapt to these new aspect ratios is essential for optimized posting and improved audience retention.
This guide explains the latest ratio changes, why they matter, and how to tailor your content strategy to fully leverage them.

Updated Instagram Feed Ratio — What’s Changed?
Originally, Instagram favored the traditional square (1:1) format. Over time, vertical posts became more common. Now, the new Instagram feed ratio standardizes and slightly redefines permitted aspect sizes to better reflect mobile-first usage patterns.
Key ratio updates:
- Vertical posts now occupy the full 4:5 aspect ratio.
- Square posts remain 1:1, with higher resolution suggested.
- Horizontal posts are still allowed, but capped at 1.91:1 — less favorable visually.
- Feed previews are optimized for taller visuals, encouraging longer attention spans.

Old Ratio vs New Ratio — User Experience Differences
Previously, all posts were tightly cropped to fit a uniform grid. With the new update:
- Vertical content sees more screen real estate without user interaction.
- Cropping is reduced, preserving key composition details.
- Scrolling is smoother, with tall posts guiding eye movement.
These changes make vertical formats far more prominent, subtly encouraging creators to shoot and post in portrait orientation.

Why Instagram Adjusted the Feed Ratio
Instagram’s updates are responses to user behavior and competition.
Main reasons:
- Mobile-first design focus — Tall posts dominate the small screen.
- Boosting engagement — Data shows vertical posts outperform on likes, comments, and shares.
- Competitive strategy alignment — Rivals like TikTok and Pinterest already use vertical priorities.
The feed ratio change seeks to hold attention longer and deepen post interaction.

Ideal Photo Dimensions for Each Orientation
| Orientation | Aspect Ratio | Recommended Pixel Size | Notes |
|---|---|---|---|
| Vertical (Portrait) | 4:5 | 1080 x 1350 | Maximizes screen coverage |
| Square | 1:1 | 1080 x 1080 | Balanced grid aesthetics |
| Horizontal (Landscape) | 1.91:1 | 1080 x 566 | Best for panoramic visuals |
Using the recommended sizes prevents pixelation and unwanted cropping.

Best Practices for Cropping Images
Cropping influences composition and clarity under the new feed ratio rules.
Cropping tips:
- Position subjects centrally or slightly higher for vertical shots.
- Maintain safe margins around faces and text.
- Preview crops in the Instagram app before posting.
- Export in consistent aspect ratios using editing software.
Good cropping preserves narrative and visual quality.

Impact on Carousel Posts and Multi-Image Layouts
Carousel posts remain prime storytelling tools. With the updated ratios:
- Maintain identical aspect ratios across all carousel slides.
- Vertical carousels encourage stronger engagement.
- Consistency in design avoids disruptive transitions.
Plan carousels carefully for optimal feed space utilization.

Optimizing Video Content for the New Feed Ratio
Vertical video enjoys increased visibility:
- Shoot in 1080 x 1350 resolution.
- Use top/bottom areas for branding or captions.
- Avoid black borders — they waste space.
Pro Tip: Adapt vertical Instagram Reels into feed videos without stretching or cropping issues.

This proactive approach streamlines production and ensures platform compliance.
