Carousel ads are a format you choose card by card; catalog ads are built from your product catalog. Compare specs, setup and when to use each.
Carousel ads and catalog ads are not two versions of the same thing. A carousel is a format: one ad with 2 or more cards you swipe through. A catalog ad is a data source: ads built from the products in your catalog and shown to each person based on what they have done online.
That means you can choose between them on the question "do I want to hand-pick what the ad shows, or let my product catalog decide?" Pick a carousel when you have a story or a few chosen items. Pick a catalog ad when you have many products and want Meta to show each person the most relevant ones.
Creative Insights shows which creatives perform so you can repeat them.
The short answer: format vs data source
According to Meta's carousel ads guide, the carousel format lets you show 2 or more images and videos in a single ad, each with its own headline, description, link and call to action. Each image or video is called a card. You choose every card yourself.
Meta's catalog ads guide describes ads that show people the most relevant products or services from your catalog, based on their interests, intent and actions online. Meta now calls these ads with product media, and they were previously called Advantage+ catalog ads. Products are displayed for each person using events data from the Meta Pixel, app SDK or Meta on-platform signals.
Use this rule of thumb:
- You pick the cards and the order: carousel.
- The catalog and each person's behavior pick the products: catalog ad.
- The two overlap, because a catalog ad can use the carousel layout, which is why the names get confused.
Side-by-side table
| Carousel ad | Catalog ad (ads with product media) | |
|---|---|---|
| What it is | A creative format with 2 or more cards | Ads that pull products from your catalog |
| Who chooses what shows | You, card by card | Meta, per person, from your catalog |
| Content | Images and videos, each with its own headline, description and link | Product images or videos from your catalog |
| Needs a catalog | No | Yes |
| Signals used | Normal ad delivery | Events data from the Meta Pixel, app SDK or Meta on-platform signals |
| Where it runs | Placements on Facebook, Messenger, Instagram and Meta Audience Network | Sales, Traffic, Engagement, Leads or App promotion objectives |
| Where you build it | Meta Ads Manager or your Facebook Page | Ads Manager, by choosing Product media as the creative source |
| Typical use | Several products, features, a process or a story | Retargeting product viewers; reaching people who have not purchased or visited |
What each needs to run
Carousel ads
A carousel needs only creative. On Facebook, Meta's carousel ad specs set the limits:
- Cards: a minimum of 2 and a maximum of 10.
- Aspect ratios: square (1:1), 4:5 or 9:16. The 4:5 ratio is only available for catalog ads that use the carousel format and product images from your catalog.
- Images: 1:1 at 500 x 500 pixels minimum (1024 x 1024 recommended), up to 30 MB, in .jpg or .png.
- Copy limits: text 125 characters, headline 40 characters, link description 25 characters.
- Video: up to 240 minutes, with 15 seconds recommended.
Specifications vary by placement. Instagram, for example, allows 3 cards in Stories and 10 in Feed.
Catalog ads
A catalog ad needs a product catalog and signals about what people do with your products. Meta says products are displayed using events data from your Meta Pixel, app SDK or on-platform signals, so working tracking comes first. If tracking is shaky, read Conversions API vs Meta Pixel before you build.
For Sales campaigns, Meta turns on Product data by default during setup if you have a catalog. Creative options for catalog ads include dynamic overlays, image touch-ups, standard labels and image background generation, and the ads can automatically show product images or videos based on what each person is likely to engage with. For a full walkthrough of catalog setup, see Facebook ads for product catalogs.
A simple decision rule by business type
| Business | Start with | Reason |
|---|---|---|
| Store with a large catalog | Catalog ad | The catalog picks products per person; you do not hand-pick hundreds of cards |
| Store with 5 to 10 hero products | Carousel | You can choose and order the cards yourself |
| Service, course or software business | Carousel | No product catalog; cards explain steps, features or outcomes |
| Brand launching one collection | Carousel | A story across cards fits a launch |
| Store retargeting product viewers | Catalog ad | Meta lists reminding people about products they viewed but did not buy as a use case |
| Store with no catalog set up yet | Carousel | A catalog ad needs a catalog; a carousel needs only creative |
If two rows fit you, run both for a few weeks and compare, as described at the end of this guide.
When carousel ads win
Choose a carousel when you want control over the message. Meta's carousel guidance lists several uses:
- A few chosen products. Feature multiple products that link to different landing pages. Meta says this gives customers more options and can help raise clickthrough rate.
- Features of one product. Give each card one feature or benefit.
- A process. Walk people through how your business works step by step.
- A story. Use images and videos in succession to tell a narrative, or span one long image across all cards for a larger canvas.
Carousels also fit businesses without a catalog: services, courses, app promotions and local companies. If you are choosing between formats more widely, see Facebook carousel ads and types of ad creative on Meta.
When catalog ads win
Choose a catalog ad when you have more products than you could hand-pick, and your products and prices change often. Meta lists two main uses: reaching people who have shown interest in products on your website or app and reminding them about products they viewed but did not buy, and prospecting people who have not purchased or visited your website.
- Large or changing catalogs. Hand-picking cards for every product does not scale, and the catalog does the picking for you.
- Retargeting. Each person sees the products they looked at.
- Prospecting at scale. Meta can show relevant products to people who have not visited.
Using both together
You do not have to pick one. A common split is a catalog ad for retargeting and broad product reach, and a carousel for the moments where you want to tell a story, such as a launch, a bundle or a "how it works" sequence. Keep them in separate ad sets so you can read each one's results on its own.
Also remember the overlap: a catalog ad can use the carousel layout, so you can show the carousel look while the catalog decides what each person sees.
How to test and read the results
- Test one question at a time. "Hand-picked cards or catalog-chosen products?" is one test. Do not also change the offer.
- Use the same audience, budget and objective in both ad sets, and run them over the same days.
- Judge by the result you pay for. Compare cost per purchase or return on ad spend, not clicks alone. If you are unsure which to use, ROAS vs ROI explains the difference.
- Look inside the winner. A winning carousel tells you which card and hook did the work. A winning catalog ad tells you which products carried it.
- Decide in advance what counts as a clear win and how much data you need before you scale.

FAQ
What is the difference between carousel ads and catalog ads?
A carousel is a format where you choose 2 or more cards. A catalog ad pulls products from your catalog and shows each person the most relevant ones. One is a layout, the other is a data source.
What are catalog ads called now?
Meta's help page calls them ads with product media, and says they were previously called Advantage+ catalog ads. They show products from your catalog based on each person's interests, intent and actions online.
Do I need a catalog to run carousel ads?
No. A carousel only needs creative for each card. A catalog ad needs a product catalog.
How many cards can a Facebook carousel have?
From 2 to 10 cards, according to Meta's carousel ad specs. Instagram allows 3 cards in Stories and 10 in Feed.
Which is better for e-commerce?
Catalog ads suit large or changing product ranges and retargeting. Carousels suit launches, bundles and stories. Many stores run both and compare cost per purchase.
Can I use both in one campaign?
Yes, in separate ad sets so you can read the results of each. A catalog ad can also use the carousel layout.
