What Is the Best Size for a Facebook Post?
The “best” Facebook post size depends on where your content appears and what you want to achieve. Here’s the data:
Mobile users make up 98.5%of Facebook’s audience, which means your dimensions must prioritize mobile display. Photo posts already outperform text posts by 35% and video posts by 44%, but only when sized correctly.
1. Facebook Feed Post Sizes (2026)
Square Format (1080 × 1080 pixels)
| Specification | Details |
| Dimensions | 1080 × 1080 px |
| Aspect Ratio | 1:1 |
| Best For | Cross-platform content, product photos, quotes |
| Performance | Works across 80% of placements |
Square posts display consistently across desktop and mobile without cropping. This is your safest choice when you need one asset to perform everywhere.
Vertical Format (1080 × 1350 pixels) – RECOMMENDED
| Specification | Details |
| Dimensions | 1080 × 1350 px |
| Aspect Ratio | 4:5 |
| Best For | Mobile-first campaigns, lifestyle content |
| Performance | Highest mobile engagement, Meta’s preferred format |
Vertical format captures more screen space on mobile devices, leading to higher click-through rates. This is Meta’s recommended dimension for feed content in 2026.
Landscape Format (1200 × 630 pixels)
| Specification | Details |
| Dimensions | 1200 × 630 px |
| Aspect Ratio | 1.91:1 |
| Best For | Link previews, blog shares, YouTube thumbnails |
| Performance | Lower engagement than vertical/square |
Landscape format works for link sharing but occupies less mobile screen space, resulting in lower engagement metrics.
Facebook Stories Size (Complete Specs)
| Specification | Image | Video |
| Dimensions | 1080 × 1920 px | 1080 × 1920 px |
| Aspect Ratio | 9:16 | 9:16 |
| Max File Size | 30 MB | 4 GB |
| Duration | 5 seconds | 1-15 seconds |
| Format | JPG, PNG | MP4, MOV |
| Safe Zone | 1080 × 1420 px (center) | 1080 × 1420 px (center) |
Critical Safe Zone Rule
Facebook’s UI elements cover your Stories content at the top and bottom. Keep important text, logos, and CTAs within the safe zone:
- Avoid: Top 250 pixels and bottom 250 pixels
- Design within: Central 1080 × 1420 pixel area
Facebook Reels Size (2026 Update)
In June 2025, Meta unified all video content as Reels with no length restrictions. While any aspect ratio technically works, vertical format remains essential for optimal performance.
| Specification | Details |
| Recommended | 1080 × 1920 px (9:16 vertical) |
| Minimum | 540 × 960 px |
| Frame Rate | 24-60 fps |
| Max File Size | 4 GB |
| Format | MP4, MOV, GIF |
| Length | No maximum (though <3 min performs best) |
Facebook Ads Image Sizes
Ad specifications are stricter than organic posts. Using minimum dimensions causes quality issues and performance penalties.
1. Feed Image Ads
| Format | Dimensions | Aspect Ratio | When to Use |
| Square | 1080 × 1080 px | 1:1 | Cross-platform campaigns |
| Vertical | 1080 × 1350 px | 4:5 | Mobile-first ads (RECOMMENDED) |
| Minimum | 600 × 600 px (square) or 600 × 750 px (vertical) | 1:1 or 4:5 | Not recommended |
Text overlay: Keep text under 20% of image area for optimal ad delivery.
2. Stories and Reels Ads
| Specification | Details |
| Dimensions | 1080 × 1920 px |
| Aspect Ratio | 9:16 (tolerance: 1%) |
| Safe Zones | Top 250 px, bottom 340 px text-free |
| Image Max | 30 MB |
| Video Max | 4 GB |
The bottom safe zone is larger for ads (340px vs 250px) to accommodate the CTA button.
3. Marketplace Ads
| Specification | Details |
| Dimensions | 1200 × 1200 px |
| Aspect Ratio | 1:1 (required) |
| Max File Size | 30 MB |
Facebook Profile and Cover Photo Sizes
1. Profile Picture
| Specification | Details |
| Recommended Upload | 800 × 800 px |
| Minimum | 170 × 170 px |
| Display – Desktop | 170 × 170 px |
| Display – Mobile | 128 × 128 px |
| Format | Displays as circle |
Upload at 800 × 800 px even though it displays smaller – this ensures crisp quality across all devices.
2. Cover Photo
| Specification | Details |
| Recommended | 851 × 315 px |
| Mobile Display | 640 × 360 px (sides cropped) |
| Safe Zone | 640 × 312 px (center) |
| Optimal File Size | <100 KB |
Cover photos display differently on mobile versus desktop. The central 640 × 312 pixels is your guaranteed visible area.
Facebook Post Sizes by Content Type
1. Link Share Posts
| Specification | Details |
| Recommended | 1200 × 630 px |
| Minimum | 600 × 315 px |
| Aspect Ratio | 1.91:1 |
| Max File Size | 8 MB |
Link preview images use Open Graph specifications. Images smaller than 600 × 315 px display but appear significantly smaller and less engaging.
2. Carousel Posts
| Specification | Details |
| Dimensions | 1080 × 1080 px |
| Aspect Ratio | 1:1 (square only) |
| Number of Cards | 2-10 images |
| Max per Image | 30 MB |
Critical rule: All carousel images must use identical dimensions. You cannot mix aspect ratios within one carousel.
3. Multiple Image Posts
When uploading 2+ images to a standard feed post (not carousel), Facebook displays them in a grid:
| Number of Images | Display Layout |
| 2 images | Side-by-side: 245 × 246 px each |
| 3 images | Top: 492 × 245 px, Bottom two: 245 × 245 px |
| 4 images | Grid: All 245 × 245 px |
| 5+ images | Same as 4, with “+[number]” overlay on last image |
Pro tip: Design all images at 1080 × 1080 px (1:1 ratio) for multi-image posts. Facebook auto-resizes for the grid, but square originals ensure even cropping.
Common Facebook Post Size Mistakes (And How to Fix Them)
Mistake #1: Using Landscape for Mobile Audiences
Problem: Landscape images (1.91:1) occupy minimal space on mobile feeds where 98.5% of users browse.
Fix: Switch to 4:5 vertical (1080 × 1350 px) or 1:1 square (1080 × 1080 px) for mobile-first content.
Mistake #2: Ignoring Safe Zones in Stories
Problem: Text and logos get covered by Facebook’s UI elements (profile icon, buttons).
Fix: Keep all important content within the central 1080 × 1420 px area – avoid top 250 px and bottom 250-340 px.
Mistake #3: Uploading Minimum Dimensions for Ads
Problem: Using 600 × 600 px (minimum) instead of 1080 × 1080 px (recommended) causes pixelation and lower ad performance.
Fix: Always use Meta’s recommended resolutions, not minimum dimensions.
Mistake #4: Wrong Cover Photo Safe Zone
Problem: Designing cover photos at full 851 × 315 px dimensions without considering mobile cropping (90 pixels lost on each side).
Fix: Design critical elements within the 640 × 312 px central safe zone.
Mistake #5: Mixing Aspect Ratios in Carousels
Problem: Uploading 1:1, 4:5, and 1.91:1 images in the same carousel causes Facebook to crop inconsistently.
Fix: Use 1080 × 1080 px for all carousel cards – Facebook only supports uniform aspect ratios per carousel.
Technical Best Practices for Facebook Post Size
1. File Format: When to Use JPG vs PNG
| Format | Use For | Why |
| JPG | Photos, gradients, cover photos | Smaller file size, faster loading |
| PNG | Text overlays, logos, graphics | Maintains sharp edges, supports transparency |
JPG compresses better and loads faster, making it ideal for most Facebook content. PNG maintains higher quality for text but creates larger files.
2. Compression Guidelines
| Element | Recommendation |
| DPI | 72 DPI (higher provides no benefit for screens) |
| File Size | Keep under 10 MB for optimal delivery |
| Compression | Pre-compress before uploading to control quality |
Facebook automatically compresses all uploaded images. Files over 15 MB experience more aggressive compression, reducing visual quality.
3. Resolution Strategy
Don’t upload at minimum dimensions. Use recommended sizes for best results:
- Feed posts: 1080 × 1080 px or 1080 × 1350 px
- Stories: 1080 × 1920 px
- Ads: Meta’s recommended (not minimum) resolutions
Starting with higher resolution and letting Facebook downscale produces better quality than uploading at minimum dimensions.
How to Choose Facebook Post Size by Goal
| Your Goal | Best Size | Aspect Ratio | Why |
| Maximum Engagement | 1080 × 1350 px | 4:5 vertical | Captures most mobile screen space |
| Cross-Platform | 1080 × 1080 px | 1:1 square | Works on Facebook, Instagram, LinkedIn |
| Website Traffic | 1200 × 630 px | 1.91:1 landscape | Optimized for link previews |
| Brand Awareness | 1080 × 1920 px | 9:16 vertical | Full-screen Stories/Reels experience |
| Product Showcase | 1080 × 1080 px | 1:1 square | Carousel format for multiple products |
Why Vertical Format Wins for Engagement
Photo posts already outperform text by 35%, but vertical format (4:5) amplifies this advantage by:
- Occupying more screen real estate on mobile
- Capturing attention during active scrolling
- Reducing likelihood of being scrolled past
For businesses developing their social media content strategy, choosing the right format multiplies the impact of every post you publish.
Facebook Post Size Requirements: What Changed in 2025-2026
1. Major Updates
June 2025 – Video Unification:
Meta unified all video content into Reels format with no length restrictions. The previous distinction between standard videos and Reels no longer exists.
2025 – Stories Safe Area Adjustment:
Safe zones adjusted for newer mobile screen dimensions, though core recommendations (avoid top 250px, bottom 250-340px) remain consistent.
2. What Stayed the Same
| Element | Status |
| Feed post dimensions | Unchanged from 2024 |
| Profile/cover sizes | No changes |
| Ad minimum/maximum dimensions | Consistent specifications |
| File size limits | 30MB images, 4GB video maintained |
Meta maintains stability in core specifications to avoid breaking existing content workflows for businesses and creators.
How Facebook Crops Images (Prevention Guide)
1. Mobile vs Desktop Cropping Behavior
| Content Type | Desktop Display | Mobile Display | What Gets Cropped |
| Cover Photos | 851 × 315 px | 640 × 360 px | 90 px each side |
| Vertical Posts | Full display | Slight top/bottom crop | Varies by device |
| Landscape Posts | Prominent | Significantly compressed | Loses visual impact |
2. Safe Zone Implementation
To prevent critical elements from getting cropped:
- Center Important Content
Keep text, logos, faces, and CTAs in the middle third of your image.
- Use Correct Aspect Ratios
Don’t force Facebook to auto-crop by uploading mismatched dimensions.
- Test on Mobile First
Preview how content looks on a phone before publishing.
- Leave Edge Padding
Maintain 50-100 pixel padding around text elements.
- Stories Specific
The safe zone is 1080 × 1420 pixels – design within this central area.
