Resize preset # Resize Video for Facebook 16:91920 × 1080Letterbox Facebook accepts a wide range of aspect ratios across its surfaces. The main feed looks best at 1:1 square or 4:5 portrait on mobile because those formats take more vertical real estate. News Feed native and Page video library prefer 16:9 landscape at 1920x1080, which also repurposes cleanly to Instagram and LinkedIn. Stories and Reels on Facebook use 9:16 vertical. This tool focuses on the 16:9 landscape master, which you can then downstream into the other ratios for each surface. ## Resizing for Facebook in detail Facebook re-encodes every upload to match the destination viewer. That means an ultra-high-bitrate source does not improve the final viewing experience; it just takes longer to upload. Exporting at 1920x1080 with a moderate 6 to 10 Mbps H.264 bitrate gives Facebook a clean input to work with and lands the cleanest final stream in the feed player. Meta has announced multiple times that vertical video is prioritized, but the feed still intermixes square, portrait, and landscape. Landscape 16:9 with burned-in captions and a strong opening three seconds remains the most versatile format for cross-posting across Meta properties. ## Facebook video specifications | Setting | Value | Notes | | ----------------------- | ------------------------------ | -------------------------------------------------- | | Recommended feed ratio | 16:9 landscape or 4:5 portrait | 4:5 occupies more mobile feed space. | | Landscape resolution | 1920 x 1080 | Full HD; downscales cleanly to Reels and Stories. | | Portrait resolution | 1080 x 1350 (4:5) | Maximum vertical feed footprint without full 9:16. | | Stories and Reels ratio | 9:16 vertical | 1080x1920 native. | | Maximum duration (feed) | 240 minutes | Four hours for standard uploads. | | Maximum file size | 10 GB | Supports high-bitrate full-length content. | | Codec | H.264 MP4 with AAC | VP9 also supported at ingest. | ## When to use this preset #### Page post evergreen video Resize to 1920x1080 landscape so the same asset works for the Page timeline, Facebook Watch, and any embedded use on your website. #### Ad creative masters Start with a 1920x1080 master and produce variants: 1:1 for feed, 4:5 for mobile feed, and 9:16 for Stories in a single afternoon. #### Community Live replays Landscape exports match the Facebook Live viewer, so replays published after the stream look native. #### Cross-post to Instagram Meta's cross-posting tools move 16:9 cleanly between Facebook and Instagram, reducing production work. #### Business Page announcements Clean 1080p landscape video with professional captions performs consistently across organic feed and boosted posts. ## Frequently asked questions ### What is the best aspect ratio for Facebook video? For mobile feed engagement, 4:5 portrait at 1080x1350 or 1:1 square at 1080x1080 fills the most space as users scroll. For cross-surface use across Watch, ads, and embedded web players, 16:9 landscape at 1920x1080 is the safest master. Most teams produce both. ### Can I post vertical video to Facebook? Yes. Facebook Stories and Reels use 9:16 vertical at 1080x1920\. The main feed also supports 9:16 uploads, but they get letterboxed on desktop. For full vertical impact, post as a Reel or Story rather than a feed video. ### What is the Facebook video size limit? Facebook accepts uploads up to 10 GB per file and 240 minutes of duration for standard feed videos. Live streams and premium publisher tools have different limits. For most organic video posts, the practical ceiling is your upload connection speed, not the server cap. ### What format should I use for Facebook video? MP4 with H.264 video and AAC audio at 1080p. Facebook ingests many other formats including MOV, MKV, and WebM, but H.264 MP4 processes fastest and transcodes most reliably. This tool outputs that combination for every preset. ### Does Facebook compress videos? Yes, heavily. Facebook re-encodes every upload to normalize bitrates across its distribution network. Starting with a clean 1080p H.264 source at 6 to 10 Mbps produces the best post-transcode quality. Higher bitrates get capped at server side without a visible gain. ### How long can a Facebook video be? Up to 240 minutes (4 hours) for standard feed uploads. Live streams can run longer under publisher and creator program policies. For most business and creator use, clips under 3 minutes have the best completion rates; anything over 10 minutes benefits from chapters and a strong hook. ### What is Facebook's safe zone for video ads? Meta's ad safe zone for square and portrait video reserves the top 250 pixels and bottom 250 pixels for the ad chrome, including the advertiser name, CTA button, and post reactions. Keep logos, titles, and CTAs inside the center band to avoid cut-off in the feed. ## 100% Private: Your Video Never Leaves Your Device Resizing runs locally in your browser using FFmpeg compiled to WebAssembly.
