4:5 Aspect Ratio Guide for Instagram Posts and Photos
Learn how to use the Instagram 4:5 aspect ratio for crisp, eye-catching vertical posts, with optimal dimensions, tools, and shooting tips.
Understanding the 4:5 Aspect Ratio for Instagram and Social Media
The 4:5 aspect ratio is a proportional relationship between the width and height of an image or video where for every 4 units in width, there are 5 units in height. This taller-than-square format is a sweet spot for mobile-first platforms, especially Instagram, where vertical real estate in the feed captures greater viewer attention.
Mathematically:
Width : Height = 4 : 5Example:
- 1080 px wide × 1350 px tall → matches the ratio and maintains pixel density.
In photography and video composition, the aspect ratio affects both framing and how users experience your content on-screen. The 4:5 configuration is often referred to as the “vertical portrait for feed” format because it maximizes impact within the Instagram feed without extending to the full vertical 9:16 mobile frame.

Why the 4:5 Aspect Ratio is Popular on Instagram
Instagram’s feed design prioritizes tall content, giving it more space to grab attention. Taller posts hold the viewer's gaze longer before the next scroll.
Advantages of 4:5 on Instagram:
- Improved visibility: Fills more vertical space than a square image.
- Native support: No cropping of key elements.
- Professional aesthetic: Versatile for portraits, products, and lifestyle shots.
Fact: Instagram limits feed image height to 1350 pixels, making 4:5 the tallest ratio possible without cropping.

Recommended Pixel Dimensions for Best Quality
To ensure crisp, high-quality images within Instagram’s specifications, use:
- Width: 1080 pixels
- Height: 1350 pixels
These sizes maintain the 4:5 ratio and display optimally across modern devices.
Other typical 4:5 dimension sets:
- 864 × 1080 px
- 1200 × 1500 px

4:5 vs. 1:1 vs. 9:16: A Quick Comparison
Here’s how 4:5 compares with other common aspect ratios for social media:
| Aspect Ratio | Dimensions (Example) | Best Use Case |
|---|---|---|
| 1:1 (Square) | 1080 × 1080 px | Classic Instagram grid look |
| 4:5 (Vertical Portrait) | 1080 × 1350 px | Maximizing vertical feed space |
| 9:16 (Full Portrait) | 1080 × 1920 px | Stories, Reels, TikTok |
In feeds, 4:5 offers a balanced vertical composition—more height for impact than square, but without the cropping that 9:16 experiences in grid view.

Visual Storytelling Benefits of 4:5
The 4:5 ratio is favored by storytellers and content creators because:
- It guides the viewer’s gaze in a vertical path—ideal for full-body portraits, tall products, and layered scenery.
- It allows for richer backgrounds without wasted space.
- It increases the likelihood of users pausing their scroll.
Studies show vertical imagery tends to receive higher engagement on mobile-first apps compared to landscape content.

Best Practices for Shooting in 4:5
To capture content directly in 4:5:
- Enable camera grid lines to guide framing.
- Increase distance from your subject to accommodate vertical space.
- Consider both foreground and background for more immersive vertical compositions.
- Leave headroom and footroom for potential cropping.
Some mobile cameras let you select the aspect ratio before shooting, which saves editing time later.

Optimizing Resolution and Compression for Instagram
Instagram compresses uploads, but you can minimize quality loss by:
- Exporting as JPEG at 80–90% quality.
- Using the sRGB color profile.
- Keeping file size under 1 MB.
- Sticking exactly to 1080 × 1350 px to avoid unwanted scaling.
If you capture in higher resolution, resize before posting to ensure control over the final look.

Common Mistakes to Avoid with 4:5 Content
To get the most from your posts, avoid:
- Cropping out vital visual elements (e.g., tops of heads).
- Uploading low-resolution files that may appear grainy.
- Placing text too near edges where it risks being cut off in previews.
- Over-saturating or over-sharpening during edits, which looks unnatural after compression.
