Facebook Ad Sizes and Specs: Complete Guide for 2026
The most versatile Facebook ad size is 1080x1080 pixels (1:1), which works across Feed, Marketplace, Carousel and Search Results placements without cropping. For Stories and Reels, the required dimensions are 1080x1920 pixels (9:16), while a 4:5 aspect ratio — either 1080x1350px or Meta's official 1440x1800px — is recommended for maximum vertical feed space. Matching the right pixel size to each placement ensures your creative displays cleanly without unwanted cropping, wasted ad spend, or a rejected review from Meta's automated ad system.

Facebook Ad Sizes at a Glance
Before diving into each placement, here is the fastest way to check your Facebook ad size across every format. This table reflects the standard specs pulled directly from Meta's own Ads Guide, and it's the quickest reference for comparing the current Facebook ad size across placements before launching a campaign.
Keeping this table bookmarked saves time whenever a new campaign launches, since designers and marketers can cross-check dimensions without digging through Meta's help center every time a creative brief goes out.
The Five Aspect Ratios, Drawn to Scale
Every Facebook placement is one of five shapes. Exporting these five files covers the entire platform — everything else is a crop of one of them.
Facebook Feed Ad Sizes
The Feed remains the highest-traffic ad placement on Facebook, so matching the exact recommended size here has the biggest impact on delivery, cost-per-click and overall ad performance. Since the Feed serves both mobile and desktop users, Meta gives advertisers flexibility across three main shapes.
Image Ad Sizes
Meta lists 1080x1080 pixels (1:1) as the recommended minimum for square content, while vertical 4:5 creatives should use 1080x1350 pixels for the best mobile screen coverage — though Meta's official help documentation specifies a higher 1440x1800 pixel option for 4:5, so either resolution is fully supported. Landscape (16:9) creatives run at 1200x628 pixels, which suits product photography or scenic imagery better than tighter crops.
- Square
- 1080 x 1080 (1:1)
- Vertical
- 1080 x 1350 or 1440 x 1800 (4:5)
- Landscape
- 1200 x 628 (1.91:1)
- Max file size
- 30 MB
- Min width
- 600 px
Video Ad Sizes
Video ads in the Feed support 1:1 (1080x1080) and 4:5 (1080x1350) aspect ratios, with the taller 4:5 format generally recommended since it occupies more vertical space on mobile and tends to earn a longer watch time. Advertisers repurposing YouTube or TV-style landscape footage should crop carefully, since simply stretching a 16:9 clip into a square frame often distorts faces and text.
- Square
- 1080 x 1080 (1:1)
- Vertical

Carousel Ad Sizes
Carousel cards use a 1:1 aspect ratio at 1080x1080 pixels per card, keeping every card visually consistent as users swipe through the sequence. Meta allows 2 to 10 cards per carousel, with each card supporting either an image or a video — ideal for showcasing multiple products, a step-by-step tutorial, or a single panoramic image split across several frames.
- Per card
- 1080 x 1080 (1:1)
- Cards allowed
- 2 to 10

- Image or video
Facebook Stories Ad Sizes
Facebook Stories require a full-screen vertical creative at 1080x1920 pixels, matching the 9:16 aspect ratio that fills the entire mobile display without black bars on either side. Because Stories auto-advance and compete with organic content from friends and pages, the first two seconds of any image or video need to grab attention immediately.
Keep key text and calls-to-action inside the safe zone — roughly 250px from the top and 250px from the bottom — to avoid overlap with Facebook's interface elements like the profile name, reply field and navigation arrows.

- 1080 x 1920 px
- Aspect ratio
- 9:16
- Safe zone
- 250 px top & bottom
Facebook Reels Ad Sizes
Ads on Facebook Reels follow the same 1080x1920 pixel, 9:16 specifications as Stories, ensuring full-screen playback without letterboxing. Creative should be designed vertical-first rather than repurposed from horizontal Feed content, since cropping a landscape video down to 9:16 often cuts off key visual elements like faces, logos or on-screen captions.
Reels also tend to reward native-feeling content, so overly polished or clearly "ad-like" video creative often underperforms compared to casual, in-app style footage.
Facebook In-Stream Video Ad Sizes
In-stream video ads play during other video content and use a landscape 16:9 format, matching the native shape of most on-platform video content such as creator uploads and live broadcasts. A minimum resolution of 1280x720 pixels is recommended, with a maximum file size of 4GB to ensure smooth playback across both mobile data connections and desktop broadband.
Because these ads interrupt a viewer already engaged with video, keeping the opening seconds relevant to the surrounding content improves completion rates significantly.

Facebook Collection Ad Sizes
Collection ads pair a cover image or video with a grid of product images beneath it, opening into a full-screen Instant Experience when a user taps the ad. The cover creative should use 1:1 or 9:16 depending on placement, while the product grid images follow a standard square 1:1 ratio for visual consistency across every thumbnail.
This format performs especially well for retail and e-commerce advertisers who want to showcase a full catalog without forcing users to leave the app.

Facebook Marketplace Ad Sizes
Marketplace placements use a square format at 1200x1200 pixels (1:1), matching how listings display natively in the feed alongside other buy-and-sell posts. A landscape or portrait image here often triggers awkward automatic cropping, so 1:1 is the safest choice for this placement — particularly since Marketplace users are scrolling quickly and comparing multiple listings at once.
Instagram Ad Placements
Instagram placements sit inside the same Meta Ads Manager campaign, and their specs overlap almost completely with Facebook's — which means a single well-planned export set covers both platforms.
Instagram Feed
Instagram Feed ads follow the same core specs as Facebook: 1080x1080 (1:1) for square posts or 1080x1350 (4:5) for portrait, with the taller ratio generally recommended for maximum feed visibility on mobile screens, where most Instagram browsing happens.
- Square
- 1080 x 1080 (1:1)
- Portrait
- 1080 x 1350 (4:5)
Instagram Explore & Stories
Explore and Stories placements use 1080x1920 pixels at a 9:16 aspect ratio, identical to Facebook Stories specs, so one vertical creative can run across both platforms without needing a separate export or resize.
- Explore
- 1080 x 1920 (9:16)
- Stories
- 1080 x 1920 (9:16)
Additional Ad Placements (Right Column, Search, Audience Network)
Three smaller placements round out the list. None of them need a bespoke design pass — each one reuses a shape you have already exported for Feed or in-stream video.
Right Column
Uses 1200x1200 pixels (1:1), matching Marketplace specs, since it displays as a compact image ad beside the desktop Feed and rarely supports video.
1200 x 1200 (1:1)Search Results
Follows standard Feed specs at 1:1 or 1.91:1, appearing directly within a user's Facebook search results alongside organic pages and posts.
1:1 or 1.91:1Audience Network
Meta's off-platform network extends delivery to partner apps and websites, supporting native, banner and interstitial formats — typically 1:1 or 16:9 image or video depending on the partner app's layout and screen orientation.
1:1 or 16:9Specs Are the Floor, Not the Strategy
Getting the pixels right only guarantees your ad renders cleanly. What actually moves performance is the creative inside the frame — which is why it helps to study what competitors are already running in each format.
