Best 4:5 Ratio Dimensions for IG Posts and Photos
Learn ideal 4:5 ratio dimensions for Instagram, why they boost feed visibility, recommended specs, and tips for engaging vertical photo composition.
Understanding the 4:5 Aspect Ratio for Instagram Posts
If you’re aiming to boost engagement on Instagram, learning how to use the IG post 4:5 aspect ratio can make a huge difference. This portrait-oriented format (width 4 units, height 5 units) is widely favored by brands, influencers, and photographers because it maximizes vertical screen space without being cropped by Instagram’s feed layout. More vertical coverage means your content grabs attention quicker as users scroll—and that added visibility often translates into more likes, comments, and shares.

Comparing 4:5 vs 1:1 vs 16:9
While Instagram supports multiple aspect ratios, each format impacts feed presence and viewer engagement differently.
| Aspect Ratio | Format | Feed Coverage | Pros | Cons |
|---|---|---|---|---|
| 4:5 | Portrait | High | Maximizes vertical space; eye-catching; better for storytelling | Less horizontal space; may require reframing |
| 1:1 | Square | Moderate | Classic Instagram look; easy framing | Less visual impact compared to 4:5 |
| 16:9 | Landscape | Low | Great for wider scenes; cinematic feel | Minimal feed coverage; easily overlooked |

Why 4:5 Posts Perform Better in the Instagram Feed
The IG post 4:5 format typically delivers:
- More vertical space in the feed, which catches the viewer’s eye before they scroll away.
- Larger image display compared to square or landscape formats.
- Better storytelling potential for portraits, tall subjects, and infographics.
- Higher engagement rates due to immersive visuals.
Social media marketing studies show portrait-mode images outperform square images by up to 20–30% in engagement rates.
