Getting the Instagram portrait post right

The 4:5 portrait has been Instagram’s go-to tall format for years and is still the standard for carousels and cross-posting to Facebook.

Every slide follows the first one’s shape — keep them all 4:5.

The classic tall post

Carousels love 4:5. In a carousel every slide takes the shape of the first one, so designers usually build all slides at 1080×1350. Resize them together here to keep every slide identical.

Works on Facebook too. 4:5 is also the tallest uncropped feed shape on Facebook, so one 1080×1350 image can go to both networks.

On the profile grid a 4:5 post is shown as a 3:4 thumbnail, losing a thin band at the top and bottom. Keep headlines away from the very edges, or use the 3:4 post size if the grid look matters most.

Frequently asked questions

What size is an Instagram portrait post?

1080×1350 pixels, a 4:5 ratio. It is also the usual size for carousel slides.

Is 1080×1350 still a good Instagram size?

Yes. It is shown in full in the feed and remains the standard carousel size. Only the profile grid thumbnail trims it slightly.

Why do my carousel slides have different crops?

Instagram uses the first slide’s shape for all of them. Resize every slide to 1080×1350 first.

Can I post a 4:5 image on Facebook?

Yes — it is the tallest uncropped feed image there too. See the Facebook post resizer.

Are my images uploaded?

No. Resizing happens entirely in your browser. Nothing is transmitted or stored, and you can disconnect from the internet after the page loads and it still works.
