Quick answer
The carousel tips that matter most: write before you design, make slide 1 a promise and slide 2 a second hook, keep one idea per slide, end slides on small cliffhangers, put a summary slide before the end, ask for one action (a save or a send), and use the 4:5 size with the same look on every slide.
Planning: tips 1 to 5
- Write it before you design it. A carousel is an argument in slides. If the words do not work as a plain list, no design will save them.
- Pick one promise. "How to price your first client" beats "Freelancing tips". One promise per carousel; save the rest for next week.
- Choose the job: teach (saves), relate (shares), or sell (comments and DMs). Each wants a different last slide.
- Steal from your own questions. Every question a client, colleague or follower asked you twice is a carousel.
- Turn what already worked into slides. A thread, a long caption or a talk that did well is a carousel waiting to happen (here is how).
Writing: tips 6 to 11
- Slide 1 is a promise, not a title. "7 pricing mistakes that cost me $40K" over "Pricing". 15 hook formulas here.
- Make slide 2 a second hook. Mosseri has said Instagram will often give a carousel "a second chance" by showing the second slide to people who did not swipe (Adam Mosseri, via Social Media Today). It has to stand on its own.
- One idea per slide. If you need "and", you need another slide.
- End slides on a small cliffhanger. "That fixed half of it." makes the next swipe feel necessary.
- Cut every word you can. Aim for a slide that reads in about three seconds. Big text, short lines.
- Use real numbers or none. "Doubled my rate" with proof beats "10x your income" without. Readers can smell invented results.
Design: tips 12 to 16
- Go tall: 3:4 (1080 × 1440) or 4:5 (1080 × 1350). Since May 2025 Instagram shows 3:4 images "exactly as you shot it", carousels included (Instagram, via Social Media Today), and 3:4 is the taller of the two. Full size guide. For a seamless photo carousel, Edits' new carousel editor (October 2026, iOS for now) lets a photo or headline run from one slide into the next.
- Same look on every slide. Same font, colours, margins and name, so it reads as one post, not ten.
- Put a swipe cue on slide 1. An arrow or "swipe" tells people there is more.
- Keep words away from the edges. Canva advises previewing how a carousel looks in both the feed and your profile grid, because small shifts in shape change how it crops (Canva).
- Put your face and name on the slides. A tweet-style slide with your photo and handle makes every share carry your name with it.
Posting and growth: tips 17 to 21
- Add a summary slide before the end. All the points on one slide is the one people screenshot and save.
- Ask for one action. Save, send, follow or comment: pick one. Mosseri has said sends per reach correlate with reach more than anything else (AMP Agency), so "send this to someone who…" is a strong ask.
- Write a real caption. In Eden's 2026 carousel study, carousels with captions over 400 characters broke out 28.5% of the time against about 25% for short ones. Summarise the carousel, end on a question, and add alt text to each slide.
- Don't sweat hashtags or timing. The same study found the whole spread across hashtag counts was 2.6 points, and across posting hours 3.4. Posting often mattered more: creators posting 3+ carousels a week broke out 30.1% of the time.
- Fix the order later if you must. Since March 2026 you can reorder a posted carousel with a long press and drag, but you still cannot add slides (Social Media Today, March 2026). Then reuse the slides on Threads and LinkedIn, and post a Reel of the same idea (carousels vs Reels).
FAQ
What is the most important carousel tip?
Make the first slide a specific promise. If slide 1 does not earn the swipe, nothing else is seen. Our carousel hook formulas show how.
How much text should go on each carousel slide?
As little as gets the idea across, usually one or two short sentences. A slide should read in a few seconds on a phone. If it needs more, split it.
Should every slide look the same?
The look should, so the post reads as one piece: same font, colours, margins and name. The content changes slide to slide.
Do hashtags matter on carousels?
Barely. In Eden's 2026 study of 655,385 carousels, the difference between no hashtags and 11 or more was about one point of breakout rate.
How many slides should a carousel have?
More than most people think: the 2026 data favours longer carousels, as long as every slide earns its swipe. The full answer is in how many slides should a carousel have.
