What a scheduled carousel supports
Up to 10 media items per carousel, and they don’t have to be all-image or all-video — photos and videos can be mixed in the same carousel. Each item gets its own child container built against Instagram’s API, then a parent container wraps them into the single post a viewer swipes through.
Why carousels can take a moment longer to publish
Instagram’s API requires every child item — and the carousel parent container itself — to finish processing before the carousel can go live, not just the first item. A carousel with a video mixed into otherwise-static images waits on that video’s encoding the same way a standalone Reel would, so a mixed-media carousel can take a little longer to appear than an all-image one.
Counting against the daily publish limit
Whether a carousel has 2 items or the full 10, Instagram counts it as one published post toward the account’s rolling 24-hour publish cap — this is genuinely useful for anyone trying to fit more content into a limited daily volume.
How to schedule an Instagram carousel
To schedule an Instagram carousel: connect a Professional account, upload 2–10 images or videos in the order they should swipe, write one shared caption, and set a time — SkedCast builds the child and parent containers and auto-publishes it for you.
FAQ
- How many items can an Instagram carousel have?
- Up to 10 images and/or videos in a single carousel post.
- Can I auto post a carousel to Instagram, or just single images?
- Carousels auto post the same way single images do — SkedCast can auto publish a carousel to Instagram at the time you schedule it, no manual step required.
- Can I mix photos and videos in one carousel?
- Yes — Instagram’s carousel format allows mixed image and video items in the same post.
- Does a 10-item carousel use up 10 of my daily post limit?
- No — Instagram counts an entire carousel, regardless of item count, as one published post against the account’s daily publishing cap.
- Can I set alt text on individual carousel items?
- Yes — alt text can be attached per media item for accessibility.
- Can I edit one item in a carousel after it’s published?
- No — Instagram’s API does not support editing a published post, carousels included; the only option after publishing is to delete the whole post.
- Why does a carousel with a video item take longer to schedule than an all-image one?
- Every child item and the parent container must finish processing before the carousel publishes, and a video item processes the same way a standalone video does, which adds a short real delay compared to an all-image carousel.
