4x5 Ratio IG Reel Guide for Better Instagram Engagement
Learn how using the 4x5 ratio in Instagram Reels can boost feed engagement, improve composition, and keep visuals perfect in both feed and Reels.
4x5 Ratio IG Reel Guide for Better Instagram Engagement
Optimizing your Instagram Reels with the 4x5 ratio can significantly improve feed engagement without sacrificing full-screen viewing in the Reels tab. This aspect ratio maximizes vertical space in the feed, ensures better composition control, and boosts the chances of your content standing out as users scroll. In this guide, we’ll explore what the 4x5 ratio is, why it matters, and how to use it effectively for higher impressions, watch time, and interactions.

What Is the 4x5 Aspect Ratio and Why It Matters
The 4x5 aspect ratio is a vertical frame format (1080x1350 pixels) widely used for Instagram feed posts. Taller than the square 1:1 format yet shorter than the 9:16 fullscreen format, it provides the perfect middle ground for impactful previews.
Key benefits include:
- More feed space: Increased vertical real estate attracts more attention while scrolling.
- Feed preview alignment: Instagram displays Reels previews in a maximum 4x5 ratio, no matter the original format.
- Better portrait composition: Keeps visuals immersive without feeling overly stretched.

Comparing Common Instagram Aspect Ratios
To see why 4x5 shines for feed previews, compare it with the most common Instagram video ratios:
| Aspect Ratio | Pixel Dimensions (1080px width) | Best For | Drawbacks |
|---|---|---|---|
| 1:1 | 1080x1080 | Grid uniformity | Less feed space |
| 4:5 | 1080x1350 | Feed previews, portraits | Needs careful safe-zone framing |
| 9:16 | 1080x1920 | Stories, full-screen Reels | Feed crops preview to 4:5 |

Benefits of 4x5 Over Full Vertical for Feed Engagement
While 9:16 is immersive in Reels, the feed preview crops it to 4x5. Planning for 4x5 brings distinct advantages:
- Controlled cropping: Avoids losing key visuals in feed previews.
- Balanced visuals: Heads, graphics, and text stay visible in prime viewing space.
- Improved retention: Prevents awkward framing that deters viewers.

How the 4x5 Ratio Displays in Feed vs. Reels Viewer
When uploading a 9:16 Reel:
- Feed Preview: Cropped at 4:5 (1080x1350)
- Reels Viewer: Full 9:16 display
By designing content with a 4x5 safe-zone:
- Feed previews appear polished and intentional.
- Reels tab still delivers immersive visuals.

Summary and Next Steps
Implementing the 4x5 ratio IG Reel strategy allows you to work with Instagram’s feed preview limitations instead of against them.

Action step: Start your next Reel edit using a 9:16 canvas with 4:5 guides, and see how the intentional framing impacts your engagement rate.
