Understanding the 1080 x 1350 Image Size for Instagram
If you want your Instagram portrait posts to stand out and maximize engagement, then mastering the 1080 x 1350 pixel image size is essential. This resolution—1080 pixels wide by 1350 pixels tall—offers a 4:5 aspect ratio, which is perfect for grabbing attention in the feed. In this guide, you’ll learn why this size works so well, how to set it up correctly, design best practices, and tips to ensure your images remain crisp when uploaded.

Why the 4:5 Aspect Ratio Works Best on Instagram
Instagram supports several aspect ratios, but 4:5 portrait reigns supreme for feed posts because:
- It fills more of the user’s display while scrolling.
- It hits Instagram’s max display height without triggering cropping.
- It gives you more visual real estate for photography, graphics, and text.
A 4:5 ratio means the height is 1.25 times the width. So at 1080 pixels wide, you get 1350 pixels tall.

Comparing Portrait, Square, and Landscape Formats
Below is a quick comparison between the three common feed formats:
Format | Recommended Size (px) | Aspect Ratio | Feed Impact |
---|---|---|---|
Portrait | 1080 x 1350 | 4:5 | Max vertical space; high engagement potential |
Square | 1080 x 1080 | 1:1 | Balanced; common standard |
Landscape | 1080 x 608 | 1.91:1 | Wide; less vertical scroll space |
Key takeaway: Portrait dominates screen space, often resulting in a higher reach.
