Instagram Carousel size at a glance
Carousel posts in portrait 4:5 format are among Instagram's highest-engagement content types. The 1080×1350 canvas takes up more vertical feed space than square posts and supports up to 10 swipeable slides.
Why 1080×1350 matters
The 4:5 ratio occupies roughly 25% more screen real estate than a 1:1 square in the feed, giving your content a significant visibility advantage. Carousels also get re-shown by the algorithm when users don't swipe through all slides on the first pass.
What happens when the size is wrong
Mixing aspect ratios across slides forces Instagram to crop or letterbox individual frames, creating an inconsistent swipe experience. Uploading at lower resolution results in noticeable softness after compression.
Best practices
- Use the same 1080×1350 dimensions for every slide so the viewer experience is seamless.
- Place swipe cues or continuation elements near the right edge to encourage swiping.
- Keep text large and centered — each slide should deliver one clear idea at a glance.
