Facebook Ad Image Size: Every Format and Spec (2026)

Wrong ad dimensions cost you money twice — once for the wasted impression, and again when Meta's algorithm deprioritizes your ad because it looks bad. A feed ad served at the wrong aspect ratio gets cropped. A Story ad with specs built for desktop gets black bars on mobile. A carousel card uploaded at mismatched ratios forces Meta to resize every card, introducing compression artifacts.

This is the complete reference for every Facebook ad image size in 2026. It covers paid ad placements only — if you need organic post, cover, and profile specs, see our Facebook image size guide.

Master Table: All Facebook Ad Image Sizes

Use JPG for photographic creatives and PNG for graphics with sharp text or transparent elements. Upload at the recommended resolution and let Meta scale down — never upload below the minimum width.

Feed Ads: The Highest-Traffic Placement

Feed ads appear in the main Facebook scroll on desktop and mobile. They generate the majority of impressions for most campaigns. You have three aspect ratio options, and the right choice depends on your objective.

Landscape (1200 × 628, 1.91:1)

The classic Facebook ad format. Landscape fills the feed width cleanly and works well for link click campaigns because the image, headline, and link description form a cohesive unit. Use this when your ad headline and CTA text carry as much weight as the visual.

Square (1080 × 1080, 1:1)

Square ads occupy more vertical space than landscape in the mobile feed, which means more screen real estate while users scroll. For brand awareness and engagement campaigns, square outperforms landscape in most A/B tests. It is also the same ratio used in carousel and Messenger placements, making it the most versatile format if you are running one creative across multiple placements.

Portrait (1080 × 1350, 4:5)

Portrait takes up the most vertical feed space of any format — roughly 30% more than square on mobile. For single-image conversion campaigns where stopping the scroll matters, portrait gives you the largest canvas. Facebook caps the aspect ratio at 4:5; anything taller gets cropped.

Recommendation: Default to 1080 × 1080 square if your creative runs across multiple placements. Switch to 1080 × 1350 portrait for dedicated feed campaigns optimized for conversions. Use 1200 × 628 landscape only when the ad headline and link description are central to the message.

Carousel Ads

Carousel ads display 2–10 cards that users swipe through horizontally. Each card is its own image with its own headline, description, and link — making carousels ideal for showcasing multiple products, telling a sequential story, or highlighting different features.

Specs per card:

• Resolution: 1080 × 1080 pixels
• Aspect ratio: 1:1 (all cards must match)
• Max file size: 30 MB per card
• Number of cards: 2–10

Carousel ads consistently deliver higher engagement rates than single-image ads because the swipe mechanic creates active participation. Meta's algorithm can also automatically reorder carousel cards to show the highest-performing card first (unless you disable this in campaign settings).

Design tips: Make the first card compelling enough to trigger a swipe — a partial reveal, a question, or a visual that clearly continues to the next card. Put your strongest CTA on the last card, not the first. Use consistent visual styling across all cards so the carousel reads as one cohesive unit rather than a slideshow of unrelated images.

Story and Reels Ads

Stories and Reels ads fill the entire phone screen — the most immersive ad format on Facebook. Both use the same dimensions.

Specs:

• Resolution: 1080 × 1920 pixels
• Aspect ratio: 9:16 (full-screen vertical)
• Max file size: 30 MB (images), 250 MB (video)
• Video duration: up to 120 seconds for Stories, 90 seconds for Reels

Safe zones are critical. Meta overlays your Page name and "Sponsored" label in the top ~14% of the screen. A "Learn More" or CTA button sits at the bottom ~10%. Keep all essential content — logos, headline text, key visuals — in the middle 76% of the frame (roughly 250px to 1670px from the top).

Story ads that mimic organic story aesthetics outperform polished studio creatives. Full-bleed images, bold text overlays, and direct language perform better than ads that obviously look like ads.

Collection Ads

Collection ads combine a cover image or video with a grid of product images below it. When a user taps, the ad opens a full-screen Instant Experience (formerly Canvas) showcasing your catalog.

Cover image specs:

• Resolution: 1080 × 1080 pixels (square) or 1200 × 628 pixels (landscape)
• Aspect ratio: 1:1 or 1.91:1
• Max file size: 30 MB

The product grid images are pulled from your catalog feed, so their quality depends on your product image pipeline. For the cover image — which does most of the selling — use a hero product shot or lifestyle image that represents the collection. Keep text minimal on the cover since the product grid beneath it provides the detail.

Messenger Ads

Messenger ads appear in two places: the Messenger inbox (between conversations) and as Messenger Story ads.

Inbox Ads

• Resolution: 1080 × 1080 pixels
• Aspect ratio: 1:1
• Max file size: 30 MB
• Min width: 500 px

Inbox ads sit between conversation threads, so they compete with personal messages for attention. Simple, bold visuals with a clear offer outperform complex images. Users are in a messaging context — your ad should feel like an invitation, not an interruption.

Messenger Story Ads

• Resolution: 1080 × 1920 pixels
• Aspect ratio: 9:16
• Same safe zone rules as Facebook Story ads

Messenger Story ads follow the same full-screen vertical format as Facebook Stories. The same creative often works across both placements.

Right Column Ads

Right column ads are desktop-only placements that appear in the sidebar alongside the news feed. They are small, cheap, and primarily used for retargeting campaigns where brand recognition does the heavy lifting.

Specs:

• Resolution: 1080 × 1080 pixels
• Aspect ratio: 1:1
• Min width: 254 px
• Max file size: 30 MB

The display size is small — around 254 × 254 pixels rendered on screen — so fine detail and small text become unreadable. Use a single bold image (a product shot, a logo, or a face) with minimal text. These ads rely on recognition, not persuasion.

Marketplace Ads

Marketplace ads appear alongside organic product listings. Since users browsing Marketplace are already in a shopping mindset, these placements often deliver strong ROAS for e-commerce brands.

Specs:

• Resolution: 1200 × 628 pixels
• Aspect ratio: 1.91:1
• Max file size: 30 MB
• Min width: 500 px

Marketplace ads sit next to product listings with white backgrounds and clean product photography. Match that aesthetic. A heavily designed brand ad looks out of place; a clean product-on-white image blends naturally into the browsing experience and earns more clicks.

Audience Network Ads

Audience Network extends your Facebook ads to third-party apps and websites. Two primary image formats:

Banner Ads

• Resolution: 1200 × 628 pixels
• Aspect ratio: 1.91:1
• Min width: 398 px

Interstitial Ads

• Resolution: 1080 × 1920 pixels
• Aspect ratio: 9:16
• Min width: 600 px

Audience Network placements are unpredictable — your ad could appear in a gaming app, a news reader, or a utility tool. Design for maximum clarity at small sizes. Avoid relying on context that makes sense on Facebook but not in a random mobile app.

Organic Posts vs. Paid Ads: The Specs Differ

A common mistake: using organic post image specs for paid ads, or vice versa. The two have different recommended dimensions, different minimum widths, and different rendering behavior.

The safe play: always design paid ad creatives at the exact specs in the master table above. Do not reuse an organic post image as an ad creative without verifying the aspect ratio and minimum width requirements.

Meta's Text Overlay Guidelines

The old 20% text rule — where Facebook rejected ads with more than 20% text coverage — was officially retired in 2020. But the underlying logic remains baked into Meta's ad delivery algorithm. Ads with heavy text overlays receive reduced reach and higher CPMs compared to image-dominant creatives.

What this means in practice:

• You will not get a hard rejection for text-heavy ads
• But your ad will cost more per impression and reach fewer people
• Meta's own testing shows image-first creatives outperform text-heavy ones across most objectives

Practical guidelines:

• Limit text to one headline and one short supporting line on the image
• Move detailed copy to the ad text fields (primary text, headline, description) rather than baking it into the image
• Ensure text is legible at mobile size — minimum 24px equivalent on a 1080-wide canvas
• Use high-contrast text on a semi-transparent bar rather than placing text directly on a busy photograph
• If your message requires a lot of text, consider carousel format where you can spread copy across multiple cards

Design Tips for High-Performing Ad Creative

Start with the Right Facebook Ad Image Size

Resizing a landscape photo to square by cropping blindly loses critical visual information. Start with the target dimensions from the master table, or resize cleanly with Pixotter to hit exact specs without distortion.

Mobile First, Always

Over 98% of Facebook users access the platform on mobile. Design at mobile viewport size, then verify it also works on desktop — not the other way around. What looks balanced on a 27-inch monitor can become unreadable at 375 pixels wide.

Contrast Wins the Scroll

Feed ads compete with baby photos, vacation shots, and news articles. Muted, desaturated aesthetics disappear in the feed. Bold colors, sharp edges, and strong contrast between subject and background stop the thumb.

One Clear Focal Point

If a viewer cannot identify what the ad is about within two seconds, you have lost them. One product, one face, one graphic. Not a collage of four items with three lines of text.

Compress Before Uploading

Meta recompresses every uploaded image. Uploading a 20 MB uncompressed PNG means Meta's compression decides the quality tradeoff for you — and it is not gentle. Compress your image first with Pixotter to keep control of the output quality. For photographic ads, JPG at 82–85% quality hits the sweet spot between file size and visual fidelity.

Match Creative to Placement

A Story ad cropped from a feed ad looks lazy. A Marketplace ad that looks like a display banner feels out of place. Design natively for each placement, or at minimum, verify your creative works at the target aspect ratio and context before publishing.

Frequently Asked Questions

What is the best image size for Facebook feed ads?

1080 × 1080 pixels (1:1 square) is the most versatile feed ad size — it works across feed, carousel, Messenger, and collection placements. For dedicated feed campaigns focused on conversions, 1080 × 1350 (4:5 portrait) occupies more screen space on mobile and typically delivers higher engagement.

What size are Facebook Story ads?

1080 × 1920 pixels at a 9:16 aspect ratio. This fills the entire mobile screen. Keep essential content in the middle 76% of the canvas — Meta overlays UI elements at the top and a CTA button at the bottom.

Does Facebook still enforce the 20% text rule?

No. The hard limit was removed in 2020. However, Meta's delivery algorithm still penalizes text-heavy ad images with reduced reach and higher cost per impression. Keep text minimal on the image and use the ad copy fields for detailed messaging.

What file format should I use for Facebook ads?

JPG for photographs and lifestyle imagery. PNG for graphics, logos, or anything with sharp text and edges. Both formats are accepted up to 30 MB, but uploading pre-compressed files at 1–3 MB gives you better control over quality than letting Meta's compression run on a massive source file.

Are Facebook ad sizes different from organic post sizes?

Yes. Paid ads have stricter minimum width requirements (600 px for feed ads vs. 500 px for organic posts), and Meta's algorithm applies text overlay delivery penalties only to paid creatives. The recommended dimensions also differ slightly — 1200 × 628 px for landscape ads vs. 1200 × 630 px for organic posts. Always use the ad-specific specs when building paid creative.

How do I resize an image to exact Facebook ad dimensions?

Drop your image into Pixotter's resize tool, enter the target dimensions (1080 × 1080 for square, 1080 × 1920 for Story, etc.), and download. Processing happens entirely in your browser — your image never leaves your device.

What is the maximum file size for Facebook ads?

30 MB for image ads across all placements. Video ads allow up to 4 GB. While 30 MB is generous, uploading a 25 MB image means Meta's recompression will be aggressive. Pre-compress to 1–3 MB using Pixotter's compress tool for the best results.

Can I use the same image for all Facebook ad placements?

You can, but you should not. A 1:1 square image gets cropped or pillarboxed in Story placements. A 9:16 vertical image loses its impact in a landscape feed slot. For best results, create at least three versions of each creative: square (1080 × 1080) for feed and Messenger, vertical (1080 × 1920) for Stories and Reels, and landscape (1200 × 628) for Marketplace and link ads.

Pre-Launch Checklist

Before submitting your Facebook ad creative to Ads Manager:

1. Verify pixel dimensions match the target format from the master table
2. Confirm the file is under 30 MB (aim for 1–3 MB after compression)
3. Check that essential text and logos avoid the top/bottom safe zones on Story placements
4. Preview the creative on a mobile device at actual size — not just desktop
5. Verify text overlay is minimal to avoid delivery throttling
6. Compress the image before uploading to control the quality tradeoff

Getting the facebook ad image size right is the simplest, cheapest improvement you can make to ad performance. Correct specs ensure Meta delivers your creative as intended, your budget goes to impressions instead of recompression artifacts, and your audience sees the ad you designed — not a cropped, blurry approximation.
