4:5 Pixel Ratio Guide for Social Media Images
Learn how to use the 4:5 pixel ratio to maximize Instagram and Facebook feed impact with optimal dimensions, engagement tips, and design tools.
Understanding the 4:5 Pixel Ratio for Social Media Success
The 4:5 pixel ratio is a portrait-oriented aspect ratio that has become a go‑to choice for social media images — especially on Instagram and Facebook feeds. In this format, the width is 4 units and the height is 5 units, giving a slightly taller‑than‑square appearance that beautifully fills mobile screens.
A common and optimal resolution for a 4:5 image is 1080px (width) × 1350px (height). This dimension meets Instagram’s official guidelines, maintains crisp quality, and looks great across different devices without requiring users to expand the post.
Photographers, content creators, and social media managers often choose the 4:5 pixel ratio because it maximizes visibility, showcases more of the subject, and enhances engagement potential.

Why the 4:5 Ratio Dominates Instagram and Facebook
On popular platforms like Instagram and Facebook, feed space is a competitive resource. Taller images naturally command attention — they stay visible longer while the user scrolls and can effortlessly stand out in a busy feed.
The 4:5 ratio is the tallest portrait format allowed on Instagram without automatic cropping. This advantage translates to:
- Greater visibility — Users see the image on‑screen for longer duration.
- Enhanced storytelling — Portrait images capture more subject detail in the frame.
In Facebook feed ads, the same principle applies: taller visuals often deliver stronger performance, helping your content cut through the clutter.

4:5 vs. 1:1 vs. 2:3 Aspect Ratios
Not all aspect ratios perform equally. Here’s a comparison of the most common formats:
| Aspect Ratio | Example Dimensions (px) | Usage | Pros | Cons |
|---|---|---|---|---|
| 4:5 | 1080 × 1350 | Instagram portrait, Facebook feed ads | Max vertical space, ideal for mobile viewing | Horizontal images require cropping |
| 1:1 | 1080 × 1080 | Instagram standard posts | Symmetrical, easy composition | Occupies less feed space |
| 2:3 | 800 × 1200 | Photography prints, Pinterest boards | Classic photo ratio with timeless appeal | Crops in feed previews on social platforms |
Compared to 1:1 or 2:3, 4:5 strikes a balance between maximum visual impact and avoiding awkward auto‑cropping.

Guidelines for Creating 4:5 Ratio Images
1. Start with Optimal Dimensions
Build your canvas at 1080px × 1350px to protect the composition from unexpected cropping.
2. Prioritize High Resolution
For web use, 72 PPI is the minimum; go higher if your work might be repurposed for print.
3. Resize and Crop Mindfully
When converting horizontal shots:
- Crop thoughtfully to preserve your subject.
- Use neutral or thematic backgrounds to fill vertical space.
Example:
Original image: 3000 × 2000 px (3:2 ratio)
Crop to: 1080 × 1350 px (4:5 ratio)4. Lock Aspect Ratio Export Settings
Never stretch or squeeze images — maintain proportional scaling for quality and accuracy.
