Instagram Carousel Size & Dimensions

The exact dimensions Pasteup exports.
Every panel uses the same portrait dimensions, which keeps the swipe consistent and makes seam placement predictable.

The final output, numbered so the upload order stays clear.
How it works
From photos to three finished slides.
Choose Carousel
The editor opens at the fixed three-panel portrait size.
Compose across guides
Solid boundaries show where each 1080-pixel panel begins and ends.
Keep subjects clear
Move faces, products, and small text away from unintended cuts.
Export without resizing
Use the generated JPEGs directly so all panels retain matching dimensions.
Design for panels and the full swipe.
Correct dimensions prevent technical mismatch; strong composition prevents awkward cuts.
Use one ratio
Keep every uploaded carousel asset at the same aspect ratio for a consistent post.
Respect the seams
A boundary can connect images, but it should not accidentally divide a face or key detail.
Expect other previews
Instagram may crop thumbnails in some surfaces, so keep critical subjects away from extreme edges.
