Meta Ad Formats
Everything in Modules 1–5 was plumbing. Now we reach the part customers actually see — and the part that, in 2026, moves your results more than any setting: the creative. Start by knowing your formats.
The main Meta ad formats are single image, video/Reels, carousel and collection, and you should choose by objective and vertical-first, not polish. Build creative in portrait and vertical, since most impressions are on mobile.
01The formats you'll actually use
| Format | What it is | Best for |
|---|---|---|
| Single image | One static image | Simplicity, retargeting, fast testing |
| Video / Reels | Short sound-on or captioned video | Storytelling, demos, cheapest reach |
| Carousel | 2–10 swipeable cards, each with its own image & link | Showing a range, steps, or multiple products |
| Collection | A hero image/video above a mini product grid | Mobile storefront feel (needs a catalog) |
There's also Advantage+ catalog ads, which pull products straight from your feed and personalise what each person sees — powerful for e-commerce once you have a catalog connected.
The best format isn't the fanciest one — it's the one that fits your goal and the creative you can actually make well. A crisp single image often beats a mediocre video. Match format to job: video to hook and tell a story, carousel to show range, single image to state an offer clearly.
02A quick tour
Single image is the workhorse: quickest to produce and perfect for testing a message or retargeting people who already know you. Video and Reels dominate attention and typically deliver the cheapest reach — the first few seconds are everything (Lesson 6.3). Carousel lets you tell a sequence or showcase several products, with each card carrying its own headline and link. Collection creates a tap-to-browse storefront inside the app for catalog-based businesses.
03Vertical is the default now
Most people never rotate their phone. With Reels driving a huge share of impressions — and Instagram's Explore feed retired into Reels in early 2026 — vertical (9:16) and portrait (4:5) are the formats to design for first. Horizontal creative now serves a shrinking minority. We'll cover exact sizes in Lesson 6.5.
Single image/video and carousel appear directly in the format picker. As of 2026, Collection and flexible-media options moved under “Format display” settings within the ad creative, so don't panic if Collection isn't on the first screen.
Meta's Advantage+ Creative can auto-adapt your asset across placements, but its auto-crop is aggressive and often unflattering. Don't rely on one square image for everything — give Meta proper vertical and portrait versions so it isn't guessing (Lesson 6.5).
