FAQ

Frequently Asked Questions

Why is 4:5 the best ratio for Instagram engagement?

4:5 is the tallest aspect ratio Instagram allows in the feed without cropping. A taller post takes up more vertical space on a phone screen, which means more attention per scroll and typically higher engagement than 1:1 squares.

What's the exact pixel size for a 4:5 Instagram post?

1080×1350 is the recommended 4:5 size for Instagram feed posts. It matches the platform's display width (1080) and uses the maximum allowed height (1350), so Instagram won't downscale or crop.

What's the difference between 4:5 and 1:1?

1:1 is a perfect square (e.g., 1080×1080). 4:5 is taller — 4 units wide for every 5 units of height (e.g., 1080×1350). 4:5 fills more of the feed; 1:1 is the classic square look.

Will Instagram accept a 4:5 image exactly?

Yes. Instagram natively supports 4:5 portrait feed posts at 1080×1350. Upload directly — no extra cropping, no white bars added. Anything taller than 4:5 will be center-cropped by Instagram.

Why does portrait outperform square on Instagram?

Portrait posts physically occupy more pixels on a vertical phone screen, so a viewer spends more time looking at them while scrolling. More dwell time generally translates into more likes, saves, and comments.
