TLDR
Facebook's composer has no carousel option anymore — uploading multiple photos creates an album (grid display, tap-to-open viewer), and the true swipeable carousel with 2–10 linked cards now lives only in Meta's ads tooling. Your real options: design a strong multi-photo album (square 1080×1080 slides tile best), run the carousel as an ad if per-card links matter, or let Instagram — where carousels are native — be the format's home and Facebook the echo.
Why the carousel button is missing
Facebook used to let Pages publish organic swipeable carousels; Meta has since retired that path. Today the composer and Business Suite treat multiple photos as an album — a grid in the feed, not sliding cards — and the carousel format proper (swipeable cards, each with its own headline and destination link) survives only inside Meta's ads tooling. That's why every "how to make a carousel on Facebook" search leads to pages talking around the same awkward fact.
One caveat worth stating plainly: Meta reshuffles its composers constantly, and features come and go by region and account type. What follows is the capability model as of publication — the album, the ad format, and the Instagram route — rather than tap-by-tap screenshots that go stale in a quarter.
If this story sounds familiar, it's the same shape as X's: no native organic carousel, an advertiser-gated real one, and workable substitutes — we mapped that version in our guide to the carousel on X (Twitter).
Option 1: the multi-photo album, done deliberately
The album is what you actually control organically, and it has more going for it than its reputation. Upload several photos and Facebook builds a grid — the arrangement depends on the count and orientation of the images, with a "+N" overlay when there are more than fit. Tapping any image opens the full-screen viewer, where people move through the set in order: not a feed carousel, but a real sequence once the tap happens.
Designing for that double life follows three rules:
- Square slides, always. 1080×1080 tiles cleanly in every grid arrangement Facebook uses; mixed ratios get cropped unpredictably. (Conveniently, square is also the ad-carousel spec — the same exports serve both.)
- Message in the middle of every slide. Grid tiles crop edges; centered content survives any arrangement.
- Make the first image the argument. It gets the largest tile and decides whether anyone taps. Lead with the claim or the number, not a cover card.
The mechanics of multi-image posting — selection order, crop behavior — work like posting multiple photos on Instagram; the two platforms share Meta's plumbing under different layouts.
Option 2: the carousel ad, the only true carousel left
If you need actual swipeable cards on Facebook — for per-card links especially — it's an ad unit: 2–10 cards, each with its own image, headline, optional description, and destination URL, built in Meta's ads tooling. 1080×1080 (1:1) is the recommended card format — some placements support 4:5 or 9:16 — and whichever ratio you pick, it's one ratio across the set.
Whether that's worth money is a campaign question. The content answer is simpler: if you already design square carousel slides, they're valid carousel-ad creative as-is — a product-launch carousel that works organically on other platforms can be handed to whoever runs your ads without a redesign.
Option 3: let Instagram carry the format
For many creators the honest answer to "how do I post a carousel on Facebook" is: don't force it there. Carousels are native, first-class, and thriving one app over — an Instagram carousel post holds up to 20 swipeable slides with the full self-paced mechanic Facebook retired. Design the carousel for Instagram, publish it where the format lives, and give Facebook the album version of the same slides. Same content, each platform in its native shape — which beats forcing a swipe format onto a surface that now renders grids.
Designing slides that survive Facebook
Whichever option you pick, the slide work converges on one spec: square, centered, sharp. 1080×1080 squares tile cleanly in albums, match the carousel-ad card exactly, and reuse on every other platform's 1:1 option. Keep the message inside the middle ~70% of each slide so grid crops can't amputate it, and export clean PNGs — Facebook's compression, like everyone's, punishes pre-compressed JPGs hardest.
Design once, post everywhere Meta lets you
The manual path: design a square slide set, keep the message centered, export sharp PNGs — then post them as a deliberate album, hand them to Ads Manager as carousel cards, or publish them as an Instagram carousel and let Facebook take the echo.
The short path: xcarousel generates the designed slide set from a topic, URL, or PDF — copy, palette, layout — on an editable canvas, and the square 1080×1080 export is exactly the format all three Meta routes accept. There's no Facebook-specific preset, and none is needed: the slides are plain images, and the thinking-and-layout hour they replace is the same on every platform.
