Crop an image to 4:5 (portrait)

Why 4:5 wins feed space

4:5 means four wide for every five tall, slightly taller than a square. On a phone it fills roughly 25 percent more vertical screen than 1:1, which stops the scroll, while staying within the maximum height a feed will display without trimming.

That ceiling matters. Post something taller than 4:5 to Instagram and it crops the ends to fit, cutting your composition. Crop to 4:5 first and the feed shows exactly what you framed. For the wider Instagram picture across all its formats, see crop for Instagram.

Framing for a tall portrait

4:5 favors vertical subjects: a standing person, a tall product, a portrait headshot. Keep the subject centered in the taller box, leaving a little headroom at the top so nothing feels cramped against the edge.

If your source is landscape, 4:5 will crop the sides hard. Slide the box to the key part of the scene, and accept that a wide photo loses a lot of its width to become a tall post.

Crop to 4:5, then size it

A 4:5 Instagram portrait is commonly 1080x1350 pixels. Crop to the ratio here, then resize to 1080x1350 so it uploads at the exact size the feed displays, sharper than letting the app downscale a larger file.

The whole crop happens on your device, with nothing uploaded. Frame the portrait, download, and post.
