Facebook Video Dimensions 2026: Complete Size Guide for All Formats

Facebook supports multiple video formats across Feed posts, Stories, Reels, and Live streaming, each with specific dimension requirements. Understanding the correct Facebook video dimensions ensures your content displays properly without black bars, cropping, or quality loss. This comprehensive guide covers exact specifications, technical requirements, and best practices for all Facebook video formats in 2026.

Quick Reference: Facebook Video Dimensions

Format	Dimensions	Aspect Ratio	Max Duration
Feed (Landscape)	1280×720 pixels	16:9	240 minutes
Feed (Square)	1080×1080 pixels	1:1	240 minutes
Feed (Vertical)	1080×1350 pixels	4:5	240 minutes
Facebook Reels	1080×1920 pixels	9:16	90 seconds
Facebook Stories	1080×1920 pixels	9:16	60 seconds
Facebook Live	1280×720 pixels	16:9	8 hours

Facebook Feed Video Specifications

Facebook Feed videos support three aspect ratios: landscape (16:9), square (1:1), and vertical (4:5). Choose the format that best matches your content and audience viewing habits.

Landscape Feed Videos (16:9)

Landscape videos work best for horizontal content like tutorials, vlogs, and traditional video production. This format mimics television and YouTube, making it familiar to viewers. However, on mobile devices (where most Facebook viewing occurs), landscape videos occupy less vertical screen space than square or vertical formats.

Square Feed Videos (1:1)

Square videos have become Facebook’s most popular format for Feed posts. They take up 78% more screen space on mobile devices compared to landscape videos while scrolling, resulting in higher engagement rates. Square format works well for most content types and is recommended for maximum reach.

Vertical Feed Videos (4:5)

Vertical 4:5 videos maximize mobile screen real estate while still fitting well in desktop Feed. This format provides more vertical space than square while avoiding the extreme vertical orientation of 9:16 Stories and Reels. Facebook officially recommends 4:5 for Feed videos targeting mobile users.

Facebook Reels Video Specifications

Facebook Reels compete directly with Instagram Reels and TikTok, using the same vertical 9:16 format. Reels appear in the Reels tab, Feed, and can be shared to Stories. This format emphasizes mobile-first vertical video and works best with content specifically created for short-form vertical viewing.

Unlike Feed videos, Reels require vertical orientation and have stricter duration limits. Videos longer than 90 seconds cannot be posted as Reels but can be uploaded as regular Feed videos instead.

Facebook Stories Video Specifications

Facebook Stories use the same dimensions as Reels but with slightly different duration limits and functionality. Stories disappear after 24 hours unless saved to Highlights. Videos longer than 60 seconds are automatically split into multiple sequential story segments.

Stories display in full-screen vertical format on mobile devices, providing an immersive viewing experience. The 9:16 aspect ratio ensures content fills the entire screen without black bars or cropping.

Facebook Live Video Specifications

Facebook Live supports landscape, square, and vertical formats, but landscape 16:9 remains most common for live streaming. Live videos can reach up to 8 hours in length, making them suitable for extended events, Q&A sessions, and long-form content.

After a Live stream ends, the video remains on your page as a regular video post, where viewers can watch the replay. Live videos typically receive higher organic reach during the broadcast and shortly after compared to pre-recorded uploads.

Recommended Bitrates for Quality

Resolution	Frame Rate	Recommended Bitrate
720p (1280×720)	30 fps	3000-4000 kbps
1080p (1920×1080)	30 fps	4000 kbps
1080p (1920×1080)	60 fps	4000 kbps (capped)
Vertical (1080×1920)	30 fps	3000-4000 kbps
Square (1080×1080)	30 fps	3000-4000 kbps

Facebook caps video bitrate at 4000 kbps regardless of resolution. Higher bitrates are automatically reduced during upload processing. For best results, export videos at 3000-4000 kbps using H.264 codec with AAC audio at 128 kbps or higher.

Common Facebook Video Problems and Solutions

Poor Video Quality After Upload

Facebook compresses all videos during upload. Videos uploaded at low resolution or with insufficient bitrate suffer additional quality loss from Facebook’s compression.

Solutions:

• Upload at recommended resolutions (1080p for Feed, 1080×1920 for Stories/Reels)
• Use 3000-4000 kbps bitrate when exporting
• Export with H.264 codec for best compression efficiency
• Avoid uploading videos that have already been compressed multiple times
• Wait for HD processing (can take 20-60 minutes after initial upload)

Black Bars on Video

Black bars appear when your video’s aspect ratio doesn’t match the format you’re posting to. For example, uploading a 16:9 landscape video as a Reel (9:16) results in black bars on the sides.

Solutions:

• Match aspect ratio to the posting format (16:9 for Feed landscape, 9:16 for Reels/Stories)
• Crop or reframe videos in editing software before uploading
• For Feed videos, choose the aspect ratio that matches your content
• Film or edit content specifically for each format rather than repurposing

Video Gets Cropped

Facebook’s automatic cropping can cut off important content when videos don’t match exact aspect ratios.

Solutions:

• Keep important content (faces, text, key subjects) in the center 80% of frame
• Manually crop videos to exact Facebook dimensions before uploading
• Use safe zones: leave 10% margin from all edges for critical content
• Preview videos on mobile before publishing to check cropping

Upload Failed or Stuck Processing

Large files or unsupported formats can cause upload failures or indefinite processing.

Solutions:

• Ensure file size is under limits (10 GB for Feed, 4 GB for Reels/Stories)
• Use recommended MP4 format with H.264 codec
• Compress videos if necessary while maintaining quality
• Check internet connection stability during upload
• Try uploading from desktop instead of mobile (or vice versa)

Best Practices for Facebook Videos

1. Choose the Right Format for Your Content

Use Square (1:1) when:

• Targeting mobile users (most Facebook traffic)
• Creating general content that works horizontally and vertically
• Maximizing Feed visibility and engagement
• Content doesn’t require wide horizontal framing

Use Vertical (9:16) when:

• Creating Reels or Stories content
• Filming mobile-first video
• Competing with TikTok or Instagram Reels
• Content specifically composed for vertical viewing

Use Landscape (16:9) when:

• Repurposing YouTube content
• Wide horizontal scenes are essential (landscapes, group shots)
• Professional video production
• Desktop viewers are your primary audience

2. Optimize for Silent Viewing

85% of Facebook videos are watched without sound. Add captions, use visual storytelling, and ensure your message is clear even with audio muted. Facebook’s auto-caption feature can help, but manual captions provide better accuracy.

3. Hook Viewers in the First 3 Seconds

Facebook’s algorithm prioritizes watch time. Videos that hook viewers immediately and maintain engagement perform better. Start with your most compelling content—don’t save it for later in the video.

4. Keep Important Content Centered

Different aspect ratios and devices crop content differently. Keep faces, text, and key subjects in the center 80% of the frame to ensure they’re visible across all viewing scenarios.

5. Test Different Aspect Ratios

Experiment with square, vertical, and landscape to see what performs best for your audience and content type. Engagement rates vary significantly by niche and audience demographics.

If you’re creating Facebook video ads, specifications differ slightly from organic posts:

Frequently Asked Questions

What is the best video size for Facebook?

For Feed videos, 1080×1080 pixels (1:1 square) provides the best engagement on mobile devices. For Reels and Stories, use 1080×1920 pixels (9:16 vertical). Square videos take up 78% more screen space on mobile than landscape videos while scrolling.

Does Facebook support 4K video?

Yes, Facebook supports 4K video upload (3840×2160 pixels), but most viewers won’t see 4K quality due to device limitations and Facebook’s compression. For most purposes, 1080p provides sufficient quality with more manageable file sizes.

Why does my Facebook video look blurry?

Blurry videos typically result from uploading at too low resolution, insufficient bitrate, or Facebook’s compression. Always upload at 1080p resolution with 3000-4000 kbps bitrate using H.264 codec. Wait for HD processing to complete (20-60 minutes after upload).

Can I upload vertical videos to Facebook Feed?

Yes, Facebook Feed accepts vertical videos. Use 4:5 aspect ratio (1080×1350) for best results, or 9:16 for Reels/Stories. Extreme vertical formats (like 9:16) display smaller in desktop Feed but work well on mobile.

What’s the difference between Facebook Reels and Stories?

Both use 1080×1920 pixels (9:16), but Reels last up to 90 seconds and remain on your profile permanently, while Stories last 60 seconds and disappear after 24 hours. Reels can be discovered by non-followers; Stories are primarily for existing followers.

How long can Facebook videos be?

Feed videos can be up to 240 minutes (4 hours) long. Reels are limited to 90 seconds, Stories to 60 seconds per segment, and Live streams to 8 hours continuous. Most engagement occurs in the first 60 seconds regardless of total length.

Should I upload videos directly to Facebook or share YouTube links?

Upload directly to Facebook (“native video”) for significantly better reach. Facebook’s algorithm heavily favors native video over external links. Native videos autoplay in Feed and receive higher priority in the algorithm.

What frame rate should I use for Facebook videos?

30 fps is standard and recommended for most content. Facebook supports up to 60 fps, which works well for gaming, sports, or high-motion content, but increases file size without noticeable quality improvement for most video types.

Conclusion

Facebook video dimensions vary by format: use 1080×1080 (1:1) for Feed videos targeting mobile users, 1080×1920 (9:16) for Reels and Stories, and 1280×720 or 1920×1080 (16:9) for landscape content and Live streams. Square and vertical formats significantly outperform landscape videos in mobile Feed engagement.

For best results, upload at recommended resolutions with 3000-4000 kbps bitrate using H.264 codec and AAC audio. Add captions for silent viewing, hook viewers in the first 3 seconds, and keep important content centered to account for different aspect ratios and crops across devices.
