Instagram and LinkedIn carousels: how to make one people read to the last slide
The carousel is one of the most effective formats for a small business. It lets you explain, walk through a process or compare options. People save it and share it, which makes it a great way to show what you know.
But a poorly built carousel gets abandoned at slide two. Here’s how to structure one so people swipe all the way through.
Why carousels work
- They hold attention: every swipe is an interaction, and time spent on the post goes up.
- They get saved: useful, step-by-step content is something people want to come back to.
- They get shared: a clear checklist or method is easy to send to a coworker.
- They show your expertise without filming a video or talking on camera.
The structure that works, slide by slide
- Slide 1, the hook: a clear promise or a specific problem. Example: “5 mistakes that scare off your customers on Instagram.”
- Slide 2, the context: why the topic matters and what the reader will get out of it.
- Slides 3 to 7, the content: one idea per slide, with a short headline and one or two sentences of explanation.
- Second-to-last slide, the recap: the whole thing summed up in one image, the one people save.
- Last slide, the call to action: save, comment, send a DM, check out your offer.
Six to ten slides is a good balance: enough to deliver real value, short enough that people finish it.
Design rules
- Go vertical (4:5 on Instagram): it takes up more room in the feed.
- One idea per slide, with a headline you can read on a phone without zooming in.
- Keep text light: if a slide needs more than 30 words, split it in two.
- Stay consistent: same colors, same fonts, same layout from one carousel to the next.
- Use strong contrast between text and background.
- Add a visual cue on the first slide (an arrow, “save this”) to invite the swipe.
Instagram vs. LinkedIn: what’s different
On Instagram, a carousel is posted as a series of images (or videos). The tone can be more visual and more direct. The caption backs up the first slide and should open with a hook of its own.
On LinkedIn, carousels are usually posted as a PDF document: each page becomes a slide. The tone is more professional, and the examples lean toward business results. The text above the document matters as much as the document itself.
The same carousel can work on both networks: just adjust the export format, the tone of the caption and the call to action.

The caption that goes with it
The caption isn’t a summary of the carousel. It restates the hook in a different way, adds context or a quick story, and ends with a question or a call to action. On Instagram, add a few specific hashtags rather than a long list.

Frequently asked questions
How many slides should a carousel have?
Six to ten slides for most topics. Instagram allows more, but a longer carousel has to earn every extra slide.
What image size should I use for an Instagram carousel?
Portrait 4:5 (1080 × 1350 pixels) is the most common, because it takes up more space in the feed. Every slide in a carousel should use the same size.
How do I post a carousel on LinkedIn?
Export your slides as a single PDF, then add it as a document to a new post. Give the document a title: it shows above the slides.
