Use a single image ad when you have one clear message and want a fast test. Use a carousel when you have several products, several features or a story that needs steps. Neither wins every time, so test both with equal spend on your own account.

## Side by side

| | Single image ad | Carousel ad |
|---|---|---|
| What it is | One image, one headline, one link | 2 to 10 cards on Facebook and Instagram feed, each with its own headline, link and call to action |
| Best for | One offer, one product, a clear hook | A range, a catalogue, product features, a process |
| Effort to make | Low | Higher: one asset per card |
| Risk | One message to carry the whole ad | People may swipe past the first card |
| Where it shows | Most placements | Facebook, Messenger, Instagram and Audience Network |

Limits and use cases are from Meta's help pages on [carousel ads](https://www.facebook.com/business/help/773889936018967) and [carousel design specifications](https://www.facebook.com/business/help/1114358518575630), checked 2026-10-20.

## What Meta says carousels are good for

Meta lists these uses:

- Feature several products that link to different landing pages
- Highlight several features of one product
- Tell a story or explain a process
- Show one large image spread across all cards

Meta also notes that a carousel may appear as a slideshow video when it expects that to help results.

## Limits worth knowing

- Cards: 2 minimum, 10 maximum on Facebook and on Instagram feed. Instagram Stories allows 3.
- Facebook accepts 1:1 or 9:16. The 4:5 shape is only for Advantage+ catalogue carousels.
- Instagram feed uses 1:1 or 4:5. Images are JPG or PNG up to 30 MB.
- Facebook text is 125 characters and the headline 40.

## A worked example

Say you sell four kurtas priced from INR 1,299 to INR 1,899. You test for five days on the same audience, and each ad spends INR 2,500 in total. These numbers are made up.

| | Single image (best seller) | Carousel (all four) |
|---|---|---|
| Spend | INR 2,500 | INR 2,500 |
| Link clicks | 300 | 380 |
| Cost per click | INR 8.33 | INR 6.58 |
| Purchases | 5 | 4 |
| Cost per purchase | INR 500 | INR 625 |

The carousel won on clicks, but the single image won on purchases. Judge by [cost per purchase](/glossary/cpa), not cost per click. Five days is a small sample, so run it longer before you act. See [how to build a creative testing budget](/guides/how-to-build-a-creative-testing-budget).

If your catalogue is large, [Advantage+ catalog ads](/glossary/advantage-plus-catalog-ads) build the cards for you from your product feed.

Marxx reads your connected Meta ad account in full and tags creative by hook, angle, format and offer, so you can see carousels against single images in your own results. We make it, so weigh that. See [creative intelligence](/features/creative-intelligence).

## FAQ

### Do carousels get better results than single images?

Not always. It depends on your product, offer and audience. Test both with equal budgets and compare cost per purchase or lead.

### How many cards should a carousel have?

Meta allows 2 to 10 on feed. Put your strongest card first, since many people never swipe.

### Can a carousel use video?

Yes. Meta says a carousel can mix images and videos. Instagram Stories carousels are capped at 3 cards and 15-second videos, so check the placement before you build.
