Listicle
A counted set of items. The most forgiving structure because each slide stands alone — a reader who drops at slide four still got value.
4–12 slides · best at 7
6 carousel structures with a brief for every slide. Pick an arc, set the length, and write into the shape rather than guessing at it.

Hook
State the count and the payoff. The number sets the contract.
Item
One item, named in the first three words. Detail underneath.
Item
Next item. Keep the same shape as the last so the rhythm holds.

Pick
Name the one you would actually choose, and why.
Close
One line of what to do next. No hard sell.
Where this goes wrong: Promising a number in the hook and delivering fewer. The count is a contract — under-deliver once and the next carousel gets scrolled.
Each one suits a different job and fails in a different way. The failure mode is usually the more useful half.

Two options weighed against each other. Works when the reader is already choosing and wants the decision narrowed, not widened.

A sequence the reader can repeat. The only structure where slide order is load-bearing — steps out of order are worse than no steps.

A single narrative across slides. Highest completion rate when it works because each slide owes the next — and the highest drop-off when the middle sags.

Named beliefs, taken apart one at a time. Structurally a listicle with conflict, which buys more attention per slide.

One example examined closely. Narrow by design — fewer readers, but the ones who stay convert hardest.

A carousel fails in its shape more often than its wording. Pick the arc first and the writing gets easier.
If a slide is not escalating, proving, or resolving something, it is padding — and padding is where readers leave.
You will not find slide limits or image dimensions here. Those change without notice and a stale spec is worse than none, so we stick to craft.
Once the structure is settled, the question is what builds and schedules it. We compared the options.
Because we have not verified them and platforms change them without announcing it. A carousel spec that is six months stale will cost you a failed upload, so we cover the part that does not expire — what each slide has to do. Check the platform's own developer docs for the numbers.
It matters more than most advice admits, but not in the way people say. There is no magic number — what matters is that the structure you chose supports the count. A story needs room to escalate; a listicle can be four slides or twelve. The planner clamps each structure to the range it works in.
The structures transfer, because they are about how attention moves across slides rather than platform mechanics. What differs is the first slide — Instagram carousels are often found via profile grid rather than a scrolling feed, which changes how much work the opener has to do.
The planner is plain JavaScript assembling structures we wrote by hand — there is no model behind it and nothing is sent anywhere. The structures come from patterns that recur across well-performing carousels, not from a dataset we can cite.
Planning is the free part. ShowsFarm renders the slides and publishes the carousel, and pays for this site. Build carousels faster →
