What Does 1080x1350 Actually Mean?
The number 1080x1350 refers to the pixel width and height of an image:
- 1080 pixels wide: Aligns with Instagram’s recommended maximum width, minimizing scaling or compression.
- 1350 pixels tall: Produces a 4:5 aspect ratio, ideal for vertical portrait posts.
A 4:5 aspect ratio offers a taller format than square posts, yet is fully displayed in feeds without cropping—perfect for maximizing visual presence.

Why 1080x1350 is Optimal for Instagram Portraits
Instagram supports multiple image orientations:
- Square (1:1 ratio, typically 1080x1080 pixels)
- Landscape (1.91:1 ratio, e.g., 1080x566 pixels)
- Portrait (4:5 ratio, 1080x1350 pixels)
On mobile screens, portrait posts occupy more vertical real estate, allowing them to dominate the visual field before users scroll past. This increased footprint can draw more attention, fostering higher engagement.
