Instagram carousel formula: what goes on every slide

A carousel works when every slide has one job. Slide 1 stops the scroll in three to five words, slide 2 gives one line of context and a comment-keyword offer, each middle slide carries a single idea, and the last slide asks for one action.

That's the order we build every carousel in, week after week. Below, we walk through why each slide does what it does, using a Jaipur block-print label as the example, and the slide limits worth knowing before you start designing.

Why shouldn't slide 1 be a headline?

A headline answers someone who arrived with a question. They searched "how to style a block-print dupatta", and the headline tells them they're in the right place.

A cover has a harder job. It has to interrupt someone who had no question at all, somewhere between a cousin's wedding photos and a cricket meme. A headline asks them to read. A hook only asks them to stop.

A headline answers someone with a question. A cover interrupts someone who had none.

So we keep covers to three to five words, set large, carrying one idea. "How to style a block-print dupatta for every occasion" is a good blog title and a dead cover. "One dupatta, five looks" stops the thumb. The cover patterns we reach for most:

• A promise with a number: "One dupatta, five looks"
• The reader's own doubt: "Too bold for office?"
• Who it's for: "For first-time block-print buyers"
• A reason to pause: "Read before you drape"

The headline still has a home: the first line of your caption, where someone who has already stopped will read it. The same thinking drives a good reel opening, and we've collected examples in our post on reel hooks.

What goes on slide 2, and why put the offer there?

Slide 2 carries two things: one line of context and a comment-keyword offer. The context tells people what the carousel is and who it's for. The offer tells them what they'll get if they comment one word.

For our Jaipur label, slide 2 reads: "Five ways to wear one Sanganeri dupatta, office to sangeet. Comment DUPATTA and we'll DM you the prices and the link."

A good offer is something people already want: a checklist, a size chart, a price list, the link. Your buyers were going to type "link?" or "kitne ka hai" anyway; the keyword simply gives that question one word. Comments and likes sit on the whole carousel post rather than on single slides, so a comment prompted by slide 2 lands on the post like any other.

• Pick one short word that's easy to type on a phone keyboard.
• Say exactly what people will get: "the prices and the link", not "more info".
• Use the same word on slide 2, the last slide and in the caption.

How much should each middle slide say?

One idea per slide: a title of about six words, set large, and one sentence underneath. In our layouts, six words is roughly where a title still reads at thumbnail size. When a slide needs a second sentence, we usually split it into two slides.

Here are the middle slides we'd write for the dupatta carousel:

1. Office: one shoulder, plain kurta. Let the print carry a white cotton kurta.
2. Brunch: knot it as a scarf. A loose knot at the neck works over a denim shirt.
3. College: wear it as a stole. Drape both ends forward over a solid tee.
4. Puja: the classic V drape. Pin it at both shoulders so it stays put.
5. Sangeet: over a solid lehenga. A plain lehenga lets the block print lead.

Each one passes the test we apply to every slide: would someone who saw only this slide still take something away? If yes, it stays.

What should the last slide ask for?

One action. We repeat the slide 2 offer word for word: "Comment DUPATTA for the prices and the link." Whoever swiped all the way to the end is your warmest reader, so don't send them hunting through your profile for a link.

Save and share requests can live in the caption. A last slide that asks for four things (follow, save, share, comment) usually gets none of them, so we pick the one that starts a conversation.

How many slides can an Instagram carousel have?

It depends on how you post. From the Instagram app, a carousel can hold up to 20 photos and videos. If a scheduling tool publishes it for you through Meta's API, the limit is 10 images, videos, or a mix of the two.

Keep every slide the same shape. In the app, the orientation you pick (square, portrait or landscape) applies to every photo and video in the post. Through the API, carousel images are cropped based on the first image, with 1:1 as the default. We design every slide at the same size as the cover.

For sharp slides, export them at least 1080 pixels wide, with an aspect ratio between 1.91:1 and 3:4. And if you add a video to a carousel, remember it isn't treated as a reel: it won't show in your Reels tab or get reels features.

Do Instagram's original-content rules apply to carousels?

Yes. The originality protections that already covered reels now apply to photos and carousels too. Accounts that mostly re-upload other people's work in photo and carousel posts are no longer eligible to be recommended across Instagram.

Adding a border, a watermark, subtitles or a credit in the caption doesn't make someone else's work original. We go through what does count, and how to check where your account stands, in Instagram's original content rules.

For carousel makers, our advice is simple: design your own slides and write your own sentences. A screenshot of another creator's tips with your logo in the corner is a re-upload with a watermark, and that doesn't count as original.

When comments on your slide 2 offer start coming in, Instoly can reply to each one with a DM. Register every spelling of the keyword yourself (DUPATTA, dupatta), because keywords have no language setting.
