How to add a different caption to each Instagram carousel slide (2026)
Instagram now lets you write a unique caption for every carousel slide. Here is how to turn on multiple captions, plan slide-level copy, and avoid the rollout gotchas.
Until June 2026 an Instagram carousel carried one caption for the whole post — ten slides, one block of text. Instagram now lets you attach a separate caption to each slide, and the text shown under the post changes as the viewer swipes. Instagram head Adam Mosseri announced it as the rollout began on June 18, 2026, and it is reaching everyone globally over roughly a week.
This is about the post text under each slide, not burned-in video subtitles — for adding subtitles to a video clip, see the captions tutorial linked below. Slide-specific captions turn carousels into a real step-by-step format: a recipe where each slide is a step, a product comparison where each slide names a trade-off, a before-and-after where each frame gets its own line. The catch is the writing — a 20-slide carousel can now mean 20 captions to plan.
This guide covers turning the feature on, writing captions that earn the swipe, and the rollout and cross-posting gotchas that trip people up.
The steps
Update Instagram and confirm you have the feature. The toggle ships in a recent app version and is rolling out gradually, so update Instagram from the App Store or Google Play first. The feature reaches accounts over about a week from June 18, 2026, so if you do not see the multiple-captions option yet, you are not doing anything wrong — check back over the following days. There is nothing to enable in Settings; the option appears inside the post composer once it reaches your account.
Start a carousel post. Tap the plus button to create a new post and select two or more photos or videos — a carousel is any post with more than one item, up to the 20-slide limit. Pick your slides in the order you want them to appear; you can reorder later, but the captions you write are tied to a slide, so a stable order saves rework. Apply any edits or filters, then continue to the caption screen.
Switch on multiple captions. On the caption screen you will see a toggle that switches between a single caption for the whole post and multiple captions, one per slide. Single is the default, so flip it to multiple captions. Nothing changes for viewers if you leave it on single — the per-slide option is entirely opt-in.
Write a caption for each slide. With multiple captions on, swipe through the slides in the posting screen and type a caption under each one. You do not have to fill every slide; leave a caption blank where the image speaks for itself. Treat each caption as the line that should be on screen the moment a viewer lands on that slide — context, a stat, a step number, or the punchline for that specific image.
Make slide one earn the swipe and the last slide convert. Slide one still does the heaviest lifting: it sets up the promise and is what most people read before deciding to swipe, so lead with the hook there. Use the middle slides to deliver the payoff one beat at a time, and put your call to action — save, follow, comment, link in bio — on the final slide where intent peaks. Per-slide captions reward a deliberate arc, not the same sentence repeated.
Keep hashtags and the searchable text in one place. Do not scatter hashtags across every slide caption. Anchor your hashtags and the main keyword-rich description on the first slide caption, which behaves most like the old single caption for discovery, and keep the per-slide captions clean and contextual. This keeps the post readable as people swipe and avoids a wall of tags interrupting the story.
Preview by swiping, then share. Before posting, swipe through your own draft and read each caption against its slide as a viewer would — mismatched text under the wrong image is the most common error. Confirm the order, fix any caption that references the wrong slide, then share. After posting you can edit captions, but reordering slides on a live post can desync caption-to-slide pairing, so get the order right before you publish.
Common gotchas
The feature is rolling out gradually from June 18, 2026. If you do not see the toggle, update the app and wait a few days — it is not a setting you can force on.
Single caption is the default. If you forget to flip the toggle, your carousel posts with one caption and no per-slide text.
Captions are tied to a specific slide. Reordering slides after writing captions — or after posting — can leave text under the wrong image. Lock the order first.
Per-slide captions are an Instagram feature. A carousel cross-posted to Facebook, LinkedIn, or a blog will not carry them — those destinations need their own copy.
This is the post text, not video subtitles. If you want spoken-word captions burned into a video slide, that is a separate workflow.
Writing 20 thoughtful captions is real work. A carousel where every slide has a forced, low-value caption reads worse than a clean single caption — only add per-slide text where it earns its place.
Where Kompozy fits
Per-slide captions are a gift for storytelling and a tax on production: a posting cadence of several carousels a week now multiplies into dozens of captions to write, slide by slide, inside the composer. Kompozy is built for exactly that volume problem. Its Carousel Posts format generates a full multi-slide post from a single source — the brand-exact slide artwork through HyperFrames plus the copy for each slide — governed by your Persona Brief so slide 1's hook, the middle beats, and the final call to action read as one consistent voice instead of fourteen captions you forced out at midnight. You review and approve a finished carousel and paste the per-slide text in, rather than starting every slide from a blank field.
The scale story is where it pays off. Point Kompozy at a blog post, a webinar, or a list of topics and it drafts a week of carousels at once, each with slide-level copy ready to drop into Instagram's multiple-captions toggle, then schedules and publishes them on autopilot — and fans the same idea into the formats other channels want, since per-slide captions do not travel to Facebook, LinkedIn, or a blog. Creator ($49/mo for 2,500 credits) covers a solo creator running a steady carousel habit; Pro ($299/mo for 18,000 credits) handles multi-brand, high-volume output; Enterprise is custom. Instagram gave carousels more room to tell a story — Kompozy is how you fill that room without it eating your week.
Frequently asked questions
How do I add a different caption to each carousel slide on Instagram?
Start a carousel post, go to the caption screen, and switch the toggle from single caption to multiple captions. Then swipe through each slide and type its caption. The displayed text will change as viewers swipe. Single caption is the default, so you have to turn the option on.
Why can I not see the multiple-captions toggle?
The feature is rolling out gradually after its June 18, 2026 launch and reaches all accounts over about a week. Update Instagram to the latest version and check again in a few days — there is no setting to enable it manually.
How many captions can a carousel have?
Instagram still caps carousels at 20 slides, so you can write up to 20 individual captions — one per slide. You can also leave some slides without a caption.
Do slide captions replace the main caption?
In practice the first slide caption does the job the old single caption did — it is the most visible text and the best place for your main description and hashtags. The remaining slide captions add context as people swipe rather than replacing that anchor.
