Why Facebook Video Size Matters

Why does Facebook ruin video quality? Why do videos post blurry on Facebook? You might think that once your video uploads to Facebook, you’re all set. But getting the video size and formatting right has a big impact on how your content performs.

  1. Better Viewer Experience: A properly sized Facebook video won’t get cropped, stretched, or show black bars.
  2. Higher Engagement: A well-sized Facebook video won’t be compressed heavily. Sharp, clear videos hold attention longer. Blurry visuals from bad compression can turn viewers away in seconds.
  3. More Visibility from the Algorithm: Facebook’s algorithm favors videos that follow its formatting rules. A small business launching a product video stands a better chance of getting seen if the video meets Facebook’s specs.
  4. Faster Load Times: Optimized Facebook video sizes load quicker and reduce bounce. For breaking news or time-sensitive content, every second counts—viewers won’t wait for a big file to buffer.

1. General Facebook Video Size (Feed, Profile, Page)

Below are the requirements on the file size, length, resolution, dimensions, video size for Facebook Feed, profile, or a business page.

Recommended Aspect Ratios:

Why is my video cropped on Facebook? This is because your video is not in the correct Facebook video size ratio. You should resize Facebook video in:

  • Landscape (16:9): This is the traditional widescreen format, ideal for cinematic content or anything designed for a broad horizontal view.
  • Vertical (9:16): 9:16 is the recommended Facebook video size ratio for mobile-first content, Stories, or Reels. Uploading in 9:16 is best if you want to maximize screen real estate on mobile.
  • Square (1:1): This Facebook video aspect ratio performs well across both mobile and desktop feeds. It's the best for engaging social media ads as it's less likely to be cropped awkwardly on different devices.
  • Portrait (4:5): A slightly less vertical option than 9:16, but still great for mobile as it occupies significant screen space without being full-screen.

Best Practices for Facebook Video Size Optimization

After you know what the best Facebook video size is, also consider these tips to make your videos shine:

  • Start with Optimal Source Quality: Before you even think about uploading, ensure your original video footage is of the highest possible quality. A well-shot, high-resolution source video will always yield better results, even after compression.
  • Fix Video Quality Issues: If your source video has flaws like blurriness or noise, address these before uploading.
  • Leverage Higher Resolutions (Upscale to 4K): Facebook supports higher resolutions like 4K, and uploading in 4K is highly recommended for the best visual quality, provided your Facebook video file size stays within limits.
  • Codec: Use H.264 for video and AAC for audio. These are widely supported and offer efficient compression, ensuring compatibility and good performance on Facebook.
  • Frame Rate: Maintain a consistent 30 or 60 fps for smoother motion.
  • Audio Quality: Clear, crisp audio is just as important as good visuals.
  • Compression Matters: Over-compressing your video can lead to significant quality loss (pixelation, artifacts). Strive for a bitrate that perfectly balances file size and visual fidelity. For 1080p, a bitrate between 5-8 Mbps for H.264 is generally good. For 4K, consider 35-45 Mbps.
  • Hook Early: Grab attention in the first 3-5 seconds, especially for feed videos and Reels. This is your window to prevent users from scrolling past.
