What's the Maximum Number of Images in a Pinterest Carousel Ad?

A Pinterest carousel ad supports a minimum of 2 and a maximum of 5 images per carousel, per Pinterest's official product specs documentation.

Image Requirements for Each Card

Non-Sales carousel ads accept JPEG or PNG files up to 20 MB per image, with an aspect ratio of either 1:1 (square) or 2:3 (portrait). Pinterest's interface for building carousels, whether PinBuilder for Ads, the bulk editor, or directly inside Ads Manager during campaign setup, applies the same per-image specs across all of them, so the limit isn't something that changes based on how the carousel gets built.

Why Pinterest's Ceiling Is Lower Than Meta's or LinkedIn's

Both Meta's Facebook and Instagram carousels and LinkedIn's Carousel ads top out at 10 cards; Pinterest's 5-image ceiling is half that. The difference reflects how people actually use Pinterest versus a feed-based platform. Pins are discovery and planning content that people often save for later, and a shorter carousel keeps the swipe-through fast enough to match that browsing behavior, rather than asking someone mid-scroll to work through a long sequence the way a product catalog carousel might on other platforms.

What Happens Below the Minimum

A single image or video with only one creative asset isn't a carousel ad at all on Pinterest, it's a Standard Pin or video ad, a separate ad format with its own specs. The 2-image floor is really the definitional line between those two ad types rather than an arbitrary rule layered onto the carousel format itself.

How This Compares Across Platforms

Lined up against the other major carousel formats, the pattern is: Meta (Facebook and Instagram) allows 2 to 10 cards, LinkedIn allows 2 to 10 cards, and Pinterest allows 2 to 5 images. An advertiser repurposing the same multi-image campaign concept across all three platforms needs to design around Pinterest's tighter 5-image ceiling first, then decide whether to extend the sequence further for Meta or LinkedIn rather than building for 10 and cutting down.

Practical Guidance

Since every image has to work within a shorter sequence than on Meta or LinkedIn, lead with the strongest image first rather than building toward a reveal, and make sure each of the 5 images can stand on its own for a Pinner who only sees part of the carousel before tapping away.

Bottom Line

Design Pinterest carousels around a maximum of 5 images that each stand on their own if someone only swipes through part of the sequence, since Pinterest's shorter ceiling rewards a tighter story more than a platform that allows 10 cards does.

Practical Guidance

• Front-load the strongest image — with only 5 slots instead of 10, the first image needs to work even harder as a standalone Pin for anyone who stops scrolling before reaching card two.
• Keep all 5 images in the same aspect ratio — mixing 1:1 and 2:3 cards in one carousel creates a visually inconsistent swipe-through, even though Pinterest technically allows either ratio per image.
