Facebook Carousel Image Size & Specs Guide

Facebook carousels let you show multiple images in a single swipeable post or ad. They're one of the highest-engagement formats on the platform — but they're also one of the easiest to get wrong. Upload the wrong size and Facebook crops each card differently. Mix aspect ratios and the layout breaks. Use small images and they come out blurry after compression.

This guide covers the exact image sizes, aspect ratios, and specs you need for Facebook carousels — for both organic posts and ads — plus the most common mistakes and how to avoid them.

What Are Facebook Carousels?

A Facebook carousel is a post or ad format that displays multiple images (or videos) in horizontally swipeable cards. Users swipe left to see each card, and each card can have its own headline, description, and link.

Organic carousels

• Available for Pages and personal profiles
• Support 2–10 image cards
• Each card links to the same post — no individual card links on organic posts
• Display at 1:1 (square) in the feed

Carousel ads

• Support 2–10 cards (image or video)
• Each card can have its own headline, description, URL, and CTA button
• Facebook may auto-add a final card with your Page profile and CTA
• Appear in feed, Stories, Marketplace, Audience Network, and right column
• Preview your ad carousel layout with the ad image preview tool

Carousels consistently outperform single-image posts for engagement because they invite interaction — swiping is a lower commitment than clicking, and each card is another chance to capture attention.

Facebook Carousel Image Sizes

The recommended size is the same for organic and ad carousels, but the spec requirements differ slightly by context.

Important: All cards in a carousel must use the same aspect ratio. If you upload a mix of square and landscape images, Facebook forces them all to the first card's ratio by auto-cropping — the results are unpredictable and usually bad.

Verify every card with the image size checker before uploading to make sure all dimensions match.

How Facebook Crops Carousel Images

Facebook uses center-based cropping for carousel cards. If your image isn't 1:1, Facebook crops from the center outward to force a square fit.

What happens with non-square images

• Landscape (e.g. 1200×630) — top and bottom get cropped. A 1.91:1 image loses roughly 40% of its height when forced to 1:1.
• Portrait (e.g. 1080×1350) — left and right edges get cropped. Content near the sides is cut off.
• Extreme ratios (e.g. 1920×1080) — severe cropping on all edges. Most of the image is lost.

Safe zone for carousel cards

Even at the correct 1:1 ratio, keep important content in the center 90% of each card. The outer 5% on each edge can be clipped slightly on some devices, and Facebook may add subtle rounded corners or padding that eats into edge pixels.

Use the safe zone visualizer to check what stays visible, and the image crop tool to pre-crop images to 1:1 before uploading.

Carousel Best Practices

• Use 1080×1080 for every card — this is the sharpest size after Facebook's compression. Anything smaller will look soft on high-density mobile screens.
• Keep all cards the same ratio — mixing ratios causes auto-cropping. Export every card at 1:1 from the same template.
• Tell a visual story — carousels work best when the cards create a sequence. Each card should add something new — a step, a feature, a product angle — not repeat the same message.
• Make card 1 the strongest — card 1 is the only card visible before swiping. If it doesn't stop the scroll, users never see cards 2–10. Put your boldest image and clearest hook on card 1.
• Use the last card as a CTA — the final card is your closing pitch. Use it for a clear call to action: "Shop Now," "Learn More," or a benefit summary.
• Keep text large and minimal — carousel cards are small on mobile. Text must be readable at thumbnail scale. Limit to 3–5 bold words per card. Check text coverage with the text overlay checker.
• Use high contrast between cards — if every card looks the same, there's no reason to swipe. Alternate colors, angles, or compositions to keep visual momentum.
• Design for mobile first — over 98% of Facebook users browse on mobile. Cards display small on phone screens. Bold colors, large subjects, and minimal detail perform best.

For carousel ads specifically

• Keep headlines under 40 characters — longer headlines get truncated on mobile. Write short, punchy headlines that complement the image.
• Use different headlines per card — each card's headline should describe that specific card, not repeat the same generic message across all cards.
• Test card order — Facebook can auto-optimize card order for ads. If you have a specific narrative sequence, disable auto-optimization in Ads Manager.
• Preview ad overlays — CTA buttons, headlines, and descriptions overlay the card. Check positioning with the ad image preview tool.

Common Carousel Mistakes

• Mixing aspect ratios across cards — this is the #1 carousel mistake. Upload one landscape and one square image and Facebook auto-crops both to match the first card. The result is unpredictable. Always use 1:1 for every card. Pre-crop with the image crop tool.
• Using low-resolution images — Facebook compresses every upload. If you start with a 500px image, it will look noticeably blurry after compression. Always use 1080×1080. Check with the image size checker.
• Putting text near card edges — edge content can be clipped by device rendering or rounded corners. Keep text and logos in the center 90%. Use the safe zone visualizer to verify.
• Making card 1 generic or weak — if the first card doesn't hook the viewer, they never swipe. Card 1 must be your strongest image with your clearest message.
• Using too many cards — more cards isn't always better. Most users swipe 3–5 cards. After that, engagement drops sharply. Use 3–5 high-quality cards rather than 10 mediocre ones.
• Not previewing the full set — each card may look fine individually but the set doesn't flow as a sequence. Preview all cards together with the carousel preview tool to check the overall layout and flow.
• Heavy text on ad carousel cards — Facebook's algorithm still deprioritizes text-heavy ad images. Keep text under 20% of the image area. Check each card with the text overlay checker.
• Forgetting the mobile experience — carousel cards appear smaller on mobile than you'd expect. Complex images with lots of fine detail become unreadable. Test with the thumbnail analyzer to check readability at small sizes.

Tools to Check Your Carousel Images

Check every card before uploading. A broken carousel wastes engagement and, for ads, wastes budget.
