Facebook Reels Video Specs 2026: Size, FPS, Bitrate and Safe Zones

Quick answer: For Facebook Reels, start with a 1080×1920 vertical timeline, export an MP4 with H.264 video and AAC audio, use a constant 30 fps when possible, and keep important text inside the center safe area. Meta officially recommends 1080p and supports modern codecs, but a conventional H.264 MP4 remains the most compatible delivery file.

Best Facebook Reels export settings

Build the edit in a 1080×1920 sequence. Exporting at the same dimensions avoids an unnecessary resize before upload. Choose H.264 in an MP4 container, enable progressive scan, use square pixels, and export with a constant frame rate. A video bitrate around 8–12 Mbps is a useful starting range for clean 1080p social video; this is a practical recommendation rather than a published Meta requirement.

1. Set the sequence to 1080×1920, 9:16.
2. Match the frame rate to the source; use 30 fps for most phone and marketing content.
3. Export H.264 MP4 with progressive scan and square pixels.
4. Use VBR around 8–12 Mbps for ordinary footage and raise it for detailed motion if the file remains manageable.
5. Export AAC stereo audio at 48 kHz.
6. Watch the exported file from beginning to end before uploading.

Safe zones for text, captions and logos

Facebook overlays interface controls, the account name, caption text and engagement buttons on top of a Reel. Do not place essential text against the bottom or right edge. Keep faces and key product details near the visual center. Burned-in captions should use short lines, generous margins and strong contrast.

Should you upload 4K?

Meta recommends 1080p for Reels. A 4K master can be useful for archiving and reframing, but it is not automatically a better delivery file. Exporting a controlled 1080×1920 version lets you manage sharpening, bitrate and text size before Meta performs its own compression.

Why a Reel looks blurry after upload

• The source was downloaded from another social platform and already compressed.
• The editor enlarged a low-resolution clip to fill a vertical frame.
• The export used a very low bitrate.
• Variable frame-rate phone footage caused timing or encoding problems.
• Fine noise, confetti, water or foliage exceeded the available compression budget.
• The viewer is on a slow connection and Facebook is temporarily serving a lower-quality rendition.

Recommended workflow for creators

Keep a high-quality editing master, then create a separate Facebook delivery export. Review it on a phone, confirm that captions remain readable, and upload the original exported file instead of forwarding it through a messaging app. If the same creative will run as an ad, check the placement preview in Meta Ads Manager because ad interfaces and organic Reels can reserve different areas.

FAQ

Is 1080×1920 the best Facebook Reels size?

Yes. It fills a 9:16 phone screen and matches Meta’s 1080p recommendation.

Should Facebook Reels be 30 or 60 fps?

Use the frame rate that fits the source. Thirty fps is the safest general delivery choice. Sixty fps can help fast motion but creates more data and does not improve footage recorded at 30 fps.

Does a higher bitrate stop all compression?

No. Facebook creates its own delivery versions. A clean source helps, but extreme bitrates do not prevent platform transcoding.
