Reddit carousel ads, built to swipe through#
Quick answer: Reddit carousel ads carry 2 to 6 image or GIF cards, each able to link somewhere different, in feed and conversation. They suit ranges, comparisons and step-by-step stories where one hero asset cannot carry the argument.

What is a carousel ad?#
A Reddit carousel ad is a promoted post with up to six swipeable cards: one headline, up to six images, and a destination URL per card. Reddit rebuilt conversation inventory so users can view and click every card, not just the first.
Cards run square at 1200 by 1200 or portrait 3:4 at 1080 by 1440, with consistent ratios across the set. The format page on Reddit carousel hub holds the current spec; the Reddit Ads hub holds the strategy.
How cards sequence a sale#
Carousels support Awareness and Reach, Traffic, Conversions, App Installs and Catalog Sales across feed and conversation, but not Lead Generation. Order the cards as an argument: hook, proof, range, price, action.
MeUndies ran promoted carousels through a conversion-lift study and reported double-digit lifts to visits, carts and purchases. Sequence beats gallery: each card should earn the swipe, not decorate it.
| Lever | What it means |
|---|---|
| Cards | 2 to 6, each with its own URL: format specs |
| Ratios | square 1200 by 1200 or portrait 1080 by 1440, never mixed |
| Objective gap | no Lead Generation; use lead gen ads for forms |
When carousels pay, and when they do not#
Run them for product ranges, feature comparisons, tutorials and multi-step offers: anywhere the buyer needs three facts, not one feeling. Ecommerce consideration lives here.
Skip them with a single hero asset. A one-card carousel is a promoted post wearing a costume, and the extra production buys nothing.
Where your cards actually show#
Feed and conversation both take carousels, so the same unit meets browsers and researchers. Landscape assets may display uncropped in the rebuilt conversation unit, but design for the small thumbnail beside live threads.
Keep text minimal on cards: conversation thumbnails punish busy creative. Simple, clean, legible at a glance, then let the swipe do the talking.
Why run carousels at all?#
Because consideration buyers compare, and a carousel is a comparison you control: your range, your order, your links, inside the thread where the comparison is happening.
The honest caveat: six mediocre cards convert worse than one strong image. Fund the photography before the format.
