A carousel ad is a single ad with up to ten swipeable cards. Each card can be an image or video, with its own headline, description and link. People swipe sideways to see more. Carousels run across most Meta placements, including Facebook and Instagram Feed, Stories and Reels, though how they display varies.
When carousels work well
| Use | Example |
|---|---|
| Product range | Five bestselling colours of a T-shirt |
| One product, several angles | Front, back, detail, in use, packaging |
| Step-by-step story | Problem, product, how to use, result, offer |
| Features | One benefit per card |
| Social proof | A customer review on each card |
Carousels give people a reason to interact with the ad, and each swipe shows more of what you sell. Swipes also count as engagement, so judge carousels on link CTR and purchases, not clicks (all). They are less suited to ideas that rely on a single strong image or a continuous video story.
Carousel settings to know
- Two to ten cards. Most brands use three to six, because few people swipe through all ten.
- Automatically show best-performing cards first. Meta can reorder cards based on performance. Turn this off if the order tells a story.
- End card. You can add a final card that links to your page or profile.
- Carousel or collection. If you want a browsing experience after the tap, collection ads open a full-screen storefront instead.
- Catalogue carousels. With Advantage+ catalog ads, cards are filled from your product catalogue and personalised for each viewer.
- Aspect ratio. Square (1:1) is the usual default for carousels, and all cards must share one ratio. Check our guide to Meta ad sizes.
How to read carousel results
Ads Manager can break results down by carousel card, so you can see clicks per card. Treat these with care. Card one always gets the most views, so it naturally gets more clicks. Compare each card's clicks with how many people likely reached it, and use the breakdown to find cards that consistently underperform.
Worked example
Example: a jewellery brand tests two ads with the same budget.
| Single image | Five-card carousel | |
|---|---|---|
| Link CTR | 1.1% | 1.6% |
| Conversion rate | 3.0% | 2.4% |
| Cost per purchase | ₹540 | ₹500 |
The carousel attracts more clicks, but some go to products people browse without buying. Here it still wins on cost per purchase. In another account the result could flip, which is why you test.
Tips for better carousels
- Make the first card work on its own. Many people never swipe.
- Use a visual thread across cards, such as the same background or model, so it feels like one ad.
- Put the price or offer on the product image only if it is part of the photo, not as small text.
- Link each card to the most relevant page, not all to the home page.
- Use flexible ad format if you'd rather let Meta decide when to show a carousel and when to show a single asset.
Frequently asked questions
How many cards can a Facebook carousel ad have?
Between two and ten cards. Each card can be an image or video with its own headline, description and link. Most brands use three to six, since few people swipe through all ten.
Are carousel ads better than single image ads?
Neither wins everywhere. Carousels suit product ranges, several angles of one product or step-by-step stories. Single images and videos suit one strong idea. Test both on cost per purchase in your own account.
Can I stop Meta from reordering my carousel cards?
Yes. Turn off the option to automatically show the best-performing cards first when building the ad. Do this when the order tells a story, such as problem, solution and result.
What size should carousel images be?
Square 1:1 images are the usual default, and every card in one carousel must use the same aspect ratio. Use high-resolution images, at least 1080 by 1080 pixels, and check Meta's current ads guide for placement-specific options.
