The recommended Facebook carousel ad size is 1:1 square at 1080x1080px per card, the standard format for carousel because it displays consistently across every card without cropping. Carousels support 2 to 10 cards, each with its own image or video, headline, and link, so every card should be sized identically for a smooth swipe experience.
Each carousel card uses the same 1:1 square format at 1080x1080px, in JPG or PNG for images or MP4 for video cards, matching the specs used across other Facebook placements. Square avoids the letterboxing that a mismatched aspect ratio would create when cards sit side by side.
A Facebook carousel supports a minimum of 2 and a maximum of 10 cards, each with an independent image or video, headline, description, and destination link. Most advertisers use 3 to 5 cards, since fewer than 3 barely qualifies as a sequence and more than 5 sees a drop-off in how many people swipe to the end.
Meta also supports an automatic ordering option that reshuffles cards for each viewer based on which ones are predicted to perform best, so testing does not always have to happen manually across separate ad sets. That option is useful once a carousel has run for a while and has performance data on each card, but for a new carousel it is usually better to control the order manually and put the strongest product or angle first, since some viewers stop swiping after the first one or two cards.
Each carousel card has its own headline, generally most effective under about 40 characters so it does not truncate on mobile, and a short description line beneath it. Primary ad text above the carousel is shared across all cards, so product-specific detail belongs in each card's individual headline, not the shared text.
A carousel performs best when the cards feel like one connected sequence rather than unrelated images, using a consistent background, color treatment, and framing across every card. Showing one product from multiple angles, or a small collection in a logical order, gives people a reason to swipe through all of them.
The hardest part of a DIY multi-angle carousel is usually not the design, it is getting consistent lighting and background across several separate photos of the same product taken at different times. An AI ad generator that works from a single source photo, such as Image2Ad, can produce multiple consistent angles or styled variations of the same product in the same square format, which removes the need to reshoot the product several times to fill out a card sequence.
Carousel works best for showing product variety, a step-by-step story, or multiple angles of one item, situations a single image cannot cover well. A single 1:1 or 4:5 image, covered in the main Facebook ad sizes guide, is usually the better choice for a straightforward hero shot or a simple promotional message.
As a rule of thumb, if the product story needs more than one image to make sense, such as before-and-after, several colorways, or a bundle of related items, carousel is worth the extra setup. If the campaign is a single clear offer built around one hero shot, a single image or video ad, sized using the full Facebook ad sizes and dimensions guide, is simpler to produce and just as effective.
Facebook carousel images should be 1:1 square at 1080x1080px per card. Using the same square format for every card keeps the swipe transition between cards seamless.
A Facebook carousel supports a minimum of 2 and a maximum of 10 cards. Most effective carousels use 3 to 5 cards, since engagement tends to drop off past that point.
Keep each card headline under roughly 40 characters and the description line under roughly 20-25 characters to avoid truncation on mobile. Save the broader offer or brand message for the shared primary text above the carousel.
Every card should share the same aspect ratio, background style, and color treatment so the sequence reads as one cohesive ad, but the content of each card, such as product angle or item, should vary to give people a reason to keep swiping.
It depends on the goal. Carousel is better for showing multiple angles, a small product collection, or a sequence. A single 1:1 or 4:5 image is usually better for a straightforward hero shot or a simple promotional message.
