Resize preset # Resize Video for Instagram Reels 9:161080 × 1920Letterbox Instagram Reels uses the same 9:16 vertical frame as TikTok at 1080x1920\. What is different is Instagram's UI chrome: the top bar is thicker, the caption bar sits higher, and the right-side action column (like, comment, share, save, audio avatar) covers more of the horizontal space. Content that works as a clean TikTok often gets partially hidden on Reels because the right action column eats roughly the right 90 pixels of the frame on most iPhones. Planning for the Reels safe zone specifically, not the TikTok one, makes a real difference in engagement. ## Resizing for Instagram Reels in detail This tool resizes any source into the 1080x1920 Instagram Reels frame. Letterbox mode preserves the full source with black bars top and bottom, useful if you shot horizontal and want every frame visible. Crop mode fills the frame by trimming the sides, which works when the subject is already centered. The output is a standard H.264 MP4 that Reels transcodes cleanly. Because Reels also appears in the main feed and Explore, not just the Reels tab, having a clean 1080x1920 source matters for visual consistency across the three surfaces. Every pixel is authored by you here, not by Instagram's automatic cropping. ## Instagram Reels video specifications | Setting | Value | Notes | | ---------------- | ------------------------ | --------------------------------------------------------- | | Aspect ratio | 9:16 | Native Reels format. | | Resolution | 1080 x 1920 | Full HD vertical. | | Maximum duration | 90 seconds for Reels | Longer clips become regular feed video. | | Minimum duration | 3 seconds | Below this, upload fails. | | Top safe zone | 250 pixels | Occluded by account handle, music label, and action menu. | | Bottom safe zone | 340 pixels | Covered by caption and tags. | | Right safe zone | 90 pixels | Reserved for the right-side action column. | | Codec | H.264 MP4 with AAC audio | Required for clean Reels playback. | ## When to use this preset #### Repurposing TikTok for Reels Take a 1080x1920 TikTok export and re-author with a right-side margin so Instagram's action column does not cover your subject. #### Brand campaigns Letterbox a polished 16:9 ad creative into 9:16 with brand bars on top and bottom that reinforce the logo. #### Recipe and how-to clips Crop a landscape overhead cooking shot into vertical to fill the Reels viewport and keep the subject central. #### Creator collab cross-posts Resize a collaborator's landscape podcast clip to 9:16 for a Reels promo, letterboxed with a quote overlay in the safe band. #### Feed repost from Stories Convert a 9:16 Story to a standalone Reel by re-exporting at 1080x1920 so the feed preview card is full resolution. ## Frequently asked questions ### What is the best size for Instagram Reels? Instagram recommends 1080 pixels wide by 1920 pixels tall in a 9:16 aspect ratio. That is the exact frame the Reels viewer uses on iOS and Android. Uploading at other sizes works but Instagram auto-crops, which often cuts important visual content without warning. ### What aspect ratio works for Reels? The native ratio is 9:16\. Square 1:1 and landscape 16:9 uploads are accepted but displayed inside a 9:16 viewport with black space around them, which looks cheap next to purpose-made Reels. Always resize to 9:16 before uploading if the goal is to look native in the Reels tab. ### Why is my Reel cropped? Instagram automatically crops uploads that do not match 9:16\. It picks a crop region based on its own content-detection heuristics, and the choice is often wrong. To control the crop yourself, resize to 1080x1920 before upload using letterbox or crop mode in this tool. ### How long can an Instagram Reel be? Reels can be up to 90 seconds long. Uploads longer than 90 seconds are allowed through the standard feed flow but do not appear in the Reels tab or Reels-specific algorithmic distribution, so the engagement profile is different. Keep Reels under 90 seconds when Reels placement is the goal. ### Does Instagram compress Reels? Yes, Instagram re-encodes every upload. Better source quality generally produces a better output, but extreme bitrates do not survive the transcode. Exporting at a moderate 10 to 15 Mbps 1080p gives the cleanest result after Instagram's server-side compression. ### What is the Reels safe zone? The safe zone is the region never covered by Instagram's UI. Top 250 pixels for the handle and music label, bottom 340 for the caption, right 90 for the action column. Your useful visual space is roughly 990x1330 in the center-left of the 1080x1920 frame. ### Can Reels be horizontal? Technically yes, but the Reels viewer shrinks a 16:9 upload into the 9:16 window with black bars above and below. That uses only about 42% of the visible area for actual content, which looks weak next to full-frame 9:16 creators. Always resize to 9:16. ## 100% Private: Your Video Never Leaves Your Device Resizing runs locally in your browser using FFmpeg compiled to WebAssembly.
