Case Study Carousel Examples: What 243 Instagram Outliers Show
Real case study carousel examples from 243 Instagram outliers, how often the format reached 2× its creator’s usual, and how to write one slide by slide.
A case study carousel takes one real person, brand or project and shows what happened and why, one step per slide. In our library, 243 of the 4,699 outlier carousels are case studies, from 70 creators, and they beat their creator’s usual by a median of 2×.
On average the format is exactly that: average. Its biggest outliers, though, share two habits worth copying. Here’s what the data shows, real case study carousel examples grouped by type, and how to write one.
Do case study carousels perform well on Instagram?
About as well as the average carousel. Each carousel is scored against its own creator’s usual: likes + comments divided by the median of up to 20 of that creator’s carousels posted closest in time. Across 11,240 scored carousels, 577 are case studies. Here’s how they compare with the whole sample:
- Beat their creator’s usual: 48.0% of case studies, against 48.9% overall
- Reached 2×: 23.7%, against 23.6%
- Reached 3×: 14.2%, against 14.6%
That puts case studies fifth of nine formats for reaching 2×. Reference posts (36.7%, from only 128 posts), lists (25.6%), how-tos (24.9%) and opinion posts (24.5%) did better. Stories (23.1%), quizzes (21.9%), news (19.0%) and showcase posts (17.9%) did worse.
So the format alone won’t lift a post. Our reading is that a case study lives or dies on its subject: the same structure about someone nobody cares about this week is just a long post. That’s an interpretation, not a proven cause, and these are creators we track rather than a random sample of Instagram.
Case study carousel examples, by type
The case-study outliers in our library fall into a few clear kinds.
1. The news-peg breakdown
The biggest case study in the library is a 15-slide post by @impact that scored 108.4×, with 3,104,759 likes and comments. Its caption opens: “Bad Bunny’s halftime show performance was nothing like the Super Bowl has ever seen before.”
Two more of the top six case studies are about Dolly Parton, posted a day apart in late August 2026. The @femaleinvest caption opens “Yesterday, Dolly Parton passed away.”
“In a world that tells women to tone it down... Be more Dolly.” — @femaleinvest, 31.2×, 26,418 likes and comments, 13 slides
“Brand case study: Dolly Parton Built A $450 Million Brand by Never Rebranding.” — @camillemoore, 14.1×, 17,460 likes and comments, 8 slides
Same subject, same week, two angles: one about a way of living, one about building a brand. The news gave readers a reason to stop; the angle gave each account its own post.
A smaller version of the same move: “Alix Earle just announced... her next angel investment” (@ruffinmitchener, 12.3×, 5 slides).
2. The person and a number
“she made $85,235 in two weeks. Nina is an ER nurse with $150,000 in student loans. Two weeks ago she started selling a $45 guide →” — @stanforcreators, 33.5×, 9,992 likes and comments, 8 slides
A result, a person and a starting point, all on the cover. The reader knows who Nina is, what she did and roughly how before swiping, and the arrow asks for the swipe. The numbers fit a wider pattern: across 6,689 first slides we’ve transcribed, those with a number reached 2× their creator’s usual 24.2% of the time, against 21.1% for those without.
3. The project breakdown
Designers and agencies use case studies to show their own work.
- “Every minute of delay costs money. We designed for the seconds that matter⏳” (@rondesignlab, 17×, 11,220 likes and comments, 16 slides)
- “The best thing AI can do…” (@aluncreative, 13.1×, 13,604 likes and comments, 15 slides)
Those are captions. The @aluncreative first slide reads “From commodity to luxury The AI Experience”: a before and an after in the opening four words. Both posts are long; our guess is that readers who swipe into a project breakdown came to see the work.
4. The personal lesson
A case study doesn’t need a brand. @jasonrewired_ scored 13.4× with a 14-slide post (21,770 likes and comments) whose first slide reads: “The birthday taps It sounded ridiculously obvious.”
It names a small, specific moment and admits up front that the lesson is simple. That borders on a story carousel, and the line between the two formats is thin. What makes it a case study is that one example carries the whole post.
5. The comment-gated breakdown
A 7-slide AI & tech case study by @albert.olgaard scored 50.4×, with 24,175 likes and comments. Its caption reads: “Comment “TEAM” for the link”.
Comments count towards every score in our library, so a post that asks for a comment to get a link will lift its own number. That doesn’t make the result less real, but compare it with care against posts that didn’t ask.

BRAND CASE STUDY: Dolly Parton Built A $450 Million Brand by Never Rebranding.
What should the first slide of a case study carousel say?
Name the subject and the result. “A brand case study” on its own is a label. The @camillemoore cover adds a person (Dolly Parton), a number ($450 million) and a twist (never rebranding).
Three patterns from our 6,689 transcribed first slides back this up:
- Six to ten words did best. First slides of 6–10 words reached 2× their creator’s usual most often (24.9%), against 19.8% for five words or fewer.
- Statements did better than questions. 48.2% of statement hooks beat their creator’s usual, against 41.3% of question hooks.
- Capitals cost a little. Mostly-capital first slides beat their creator’s usual 44.0% of the time, against 48.7% for normal case.
The @stanforcreators cover breaks the word-count pattern and still worked, so treat these as odds, not rules. More first-slide patterns are in our breakdown of carousel hooks.
How many slides should a case study carousel have?
The median case-study outlier in our library has 8 slides, the same as lists and how-tos, one more than opinion posts and one fewer than stories.
The biggest ones run longer. Of the nine top case studies above, five have 13 or more slides: @impact (15), @femaleinvest (13), @rondesignlab (16), @jasonrewired_ (14) and @aluncreative (15). Across all formats, carousels with 11–15 slides reached 2× their creator’s usual most often (27.9%) and 2–3 slide carousels least often (17.5%).
That is a correlation. Our guess is that a case study with enough evidence to fill 15 slides is often a better case study, not that extra slides did the work. Use as many slides as the story has real steps, and cut any slide that only repeats the one before.
How to write a case study carousel
- Pick a subject people already care about. A name in this week’s news, a well-known brand, a client result in your niche. The top case studies in our library lean on subjects readers recognise before they swipe.
- Find your angle. @femaleinvest and @camillemoore covered the same person in the same week with different lessons. Ask what your audience would take from it, not what happened.
- Put the subject and the result on the cover in 6–10 words. A number helps if it’s real and sourced.
- Set the scene in one slide. Who, where they started, what was at stake. The @stanforcreators cover does this in one line: an ER nurse with student loans.
- One turning point per slide. Each slide is a decision, a move or a piece of evidence, in the order it happened.
- End with the lesson, stated plainly. The reader should be able to repeat it in one sentence.
- Check every fact. A case study is a claim about a real person or business. If you can’t source a number, leave it out.

Frequently asked questions
What is a case study carousel?
An Instagram carousel that walks through one real example, a person, brand or project, to show what happened and what it teaches. In our library, 243 of the 4,699 outlier carousels are case studies, from 70 creators.
Do case study carousels get more engagement than other formats?
Not on average. In our sample of 11,240 scored carousels, 23.7% of case studies reached 2× their creator’s usual, against 23.6% overall. Reference posts (36.7%) and lists (25.6%) did better; news (19.0%) and showcase posts (17.9%) did worse.
How many slides should a case study carousel have?
The median case-study outlier in our library has 8 slides, but five of the nine top examples above have 13 or more. Use as many slides as the story has real steps, and no more.
What makes a good case study carousel topic?
In our library, the biggest case studies cover a subject readers already know: a Super Bowl halftime show, Dolly Parton, a celebrity’s investment. The rest name a specific person and result, such as a nurse who made $85,235 in two weeks.
