Instagram Carousel Design: 9 Tips for Slides People Actually Swipe

1. Treat the first slide as an ad

Most people will only ever see slide one. It has to promise something specific: a question, a number, a surprising statement. For Art Innova Dentalmed, the cover of one carousel simply asks 'How do you know it is time to book a check-up?'. It sets up the answer without giving it away.

Put your logo small and keep the headline large. If the cover is not readable at thumbnail size, rework it.

2. One idea per slide

When a slide tries to say three things, the reader says none of them. Split the content until each slide has one point. It is better to have eight light slides than five heavy ones.

3. Write for a phone held at arm's length

• Headlines: as big as the layout allows.
• Body text: never smaller than you can read on a phone without zooming.
• Maximum of around 30 to 40 words per slide.
• Strong contrast between text and background, especially over photos.

4. Use a repeatable visual system

A consistent template makes the carousel feel like one object. For the Selfconsulting engineering and architecture account, the carousels share a deep green background, a mint highlight colour, thin line graphics and the logo in the same corner. Readers feel the series before they read it.

5. Give people a reason to swipe

Visual cues help: an arrow, a slide counter, an element that runs across two slides, or a line of text that is clearly unfinished at the edge. Art Innova's service carousels use three small arrows on the cover for exactly this reason.

6. Make every slide scannable

Use lists with short items, bold the key words and keep alignment consistent. Someone should understand the slide in two seconds, and enjoy it more if they read it fully.

7. Order the slides like a story

1. Cover: the question or promise.
2. Context: why this matters.
3. The main points, one per slide.
4. A summary or example.
5. A closing slide with a single call to action.

8. Finish with one action

The last slide is where people decide what to do next. Choose one action: save, share, book, visit the site. Asking for five things gets you none.

Carousel ideas that work for most brands

• A myth versus reality slide series, as used on the KDT Romania account.
• A step-by-step guide to a process your customers find confusing.
• A list of questions to ask before buying your product or service.
• A 'what is the difference between X and Y' explainer.
• A before and after, or a checklist people will want to save.

Pick a topic you have already answered in messages from customers. That is proof that people want it.

9. Check what works, then repeat it

Look at which carousels get saved and shared, not just liked. Saves usually mean useful content. Then repeat that structure with a new topic. If you want carousels designed as a system for your brand, have a look at my social media design service.

Frequently asked questions

What size should an Instagram carousel be?

The 4:5 portrait format, 1080 by 1350 pixels, takes the most space in the feed and usually performs well. Square 1080 by 1080 also works.

How many slides should a carousel have?

As many as the idea needs. Most useful carousels have between five and ten slides. Do not pad.

Should text be in the image or in the caption?

Put the main content in the slides and use the caption for context, keywords and a call to action.
