How to make an Instagram carousel: in the app, in Canva, or with AI
A carousel is a single post that holds up to 20 photos or videos, swiped one at a time. It is the format that teaches, proves and sells best on Instagram, and in 2026 it is also the one with the highest average engagement rate of any format. Making one is easy; making one that looks designed and gets swiped is the part most guides skip.
Three methods below, from the plain in-app upload to the 20-second AI version, plus the sizes, the seamless trick, the structure that earns swipes, and the mistakes that lose them.
The short answer
In the Instagram app: tap the plus button, choose Post, tap the select-multiple icon (two overlapping squares), pick up to 20 photos or videos in the order you want them, tap Next, edit, add your caption and share. To make one that looks designed, build the slides first at 1080 by 1350 pixels (4:5) or 1080 by 1440 (3:4) in Canva or a template, then upload them in order.
To make one in about 20 seconds, type the topic into Virallized AI: it writes the hook, the slides and the caption in your brand voice, designs them in one of 30 templates with your logo and colours, and exports the set ready to upload.
Method 1: Make a carousel in the Instagram app, step by step
1. Open Instagram and tap the plus button at the bottom of the screen (or swipe right from the feed), then choose Post. 2. Tap the select-multiple icon, the two overlapping squares above your camera roll. 3. Tap your photos or videos in the order you want them to appear; a number appears on each. You can mix photos and videos, and you can add up to 20. 4. Tap Next. Instagram crops every slide to the aspect ratio of the first one, so choose the first slide deliberately. 5. Edit if you want (filters and adjustments apply per slide), tap Next again, write the caption, add up to five hashtags, tag people or a location, and tap Share.
Two things people miss. You can press and hold a slide on the selection screen to drag it into a different position before posting. And you can make a carousel on desktop too: instagram.com's Create button accepts multiple files, which is the easiest route when the slides were designed on a computer.
Method 2: Design the slides first (Canva or any template)
Uploading camera-roll photos makes a carousel; designing the slides first makes a post people save. Set your canvas to 1080 by 1350 pixels (4:5, the classic standard) or 1080 by 1440 (3:4, the tallest post-ready size, which also matches the profile grid since Instagram moved it to 3:4). Keep every slide the same size, because Instagram applies the first slide's ratio to all of them. Keep text away from the bottom edge where the caption overlay sits, and away from the very top where the account name sits.
Structure before decoration: a hook slide that states the promise, one idea per interior slide in large type, and a closing slide that says what to do next. Then export as PNG or high-quality JPEG, transfer to your phone (or post from desktop) and upload in order. The carousel size guide has the full dimension table with a live preview, and the templates gallery shows 30 real design families to borrow a structure from.
Method 3: Generate the carousel with AI
Designing ten slides by hand takes most people 30 to 60 minutes, which is why so many carousels never get made. Virallized AI removes that step: type the topic, pick a tone, a goal (saves, follows, DMs or sales) and a slide count, and it writes the hook slide, the interior slides and the closer, then lays the whole set into any of 30 designer templates with your logo, colours and saved voice, in about 20 seconds. Everything is editable before you export at Instagram's native sizes, named in posting order, ready for Method 1.
Your first five generations are free with every feature unlocked (a card on file verifies the account; nothing is charged unless you subscribe), plans start at $49 a month, and Virallized growth clients already have ten a month included. It does not post to Instagram for you: you export finished files you own.
Sizes, limits and the rules that changed
Up to 20 slides per carousel (raised from 10 in 2024). Photos and videos can be mixed. One aspect ratio per carousel, set by the first slide. Portrait 4:5 (1080 by 1350) remains the classic standard and the ceiling for video; portrait 3:4 (1080 by 1440) has been natively supported for photos since May 2025 and is now the tallest post-ready size; square 1:1 (1080 by 1080) still works but wastes screen. Hashtags are capped at five per post since December 2025. Full details, with the grid-crop preview, in the size guide.
How to make a seamless carousel that connects across slides
The panoramic effect, where one image continues across slides as people swipe, is just one wide image cut into equal 4:5 or 1:1 tiles and uploaded in order. The free grid maker does exactly this in your browser: upload the image, choose seamless carousel, pick the ratio and slide count, and download the tiles named in posting order. Nothing is uploaded to us. The same tool splits an image into profile-grid tiles without cropping the important parts.
The structure that gets swiped
Slide one is a headline, not a title: it states the specific promise (“Five mistakes that make sourdough dense”) in type big enough to read in the feed, because most people decide to swipe from the first frame alone. Slides two to eight carry one idea each, in the same layout, with a small progress cue (2/8) so readers know how far they are. The last slide asks for one thing: save this, share it with someone, DM a word, book a call. Five to ten slides is the sweet spot; twenty is available but rarely earns the swipes.
The 18 carousel ideas page has hooks written for each structure, and the Hook generator in Virallized AI produces twelve opening lines per run when slide one will not come.
Carousel mistakes that cost the swipe
A first slide that reads like a title page. Paragraphs of text where a headline should be. A different layout on every slide, so the set looks like five different accounts. Slides sized for the wrong ratio, so Instagram crops the headline. No closing slide, so the reader finishes and leaves. And the biggest: a carousel with no single idea, ten slides of general tips that nobody saves because nothing in it was specific enough to need later.
Common questions
How many photos can you put in an Instagram carousel?
Up to 20 photos or videos in a single carousel post, mixed if you like. The limit was raised from 10 in 2024. Five to ten slides is the range that tends to earn the most complete swipes.
Can you mix photos and videos in an Instagram carousel?
Yes. Select any combination on the multi-select screen and they post as one carousel. Every slide takes the aspect ratio of the first slide, so plan the first one deliberately.
What size should Instagram carousel slides be?
1080 by 1350 pixels (4:5) is the classic standard and the video ceiling; 1080 by 1440 (3:4) is the tallest post-ready size for photos and matches the profile grid. Keep every slide in a carousel the same size. Square 1080 by 1080 works but shows smaller in the feed.
How do you make a carousel from one photo that connects across slides?
Cut the wide image into equal tiles at one ratio and upload them in order. Our free grid maker does it in the browser: choose seamless carousel, pick the ratio and slide count, download the tiles named in posting order.
Can you make an Instagram carousel on desktop?
Yes. On instagram.com, use the Create button and select multiple files; they post as a carousel. It is the easiest route when the slides were designed on a computer.
Do carousels get more engagement than Reels?
By engagement rate, yes: Socialinsider's 2026 benchmark puts carousels at 0.55% on average against 0.52% for Reels and 0.37% for single images. Reels still reach more non-followers, so most accounts do best with carousels for teaching and Reels for discovery.
