Instagram Reel size in 2026: aspect ratio, resolution, cover size and the safe zone
The Instagram Reel size that fills a phone screen is 1080 x 1920 pixels, a 9:16 vertical frame. Instagram's own help page states that a reel can be uploaded at any aspect ratio between 1.91:1 and 9:16, with a minimum resolution of 720 pixels and a minimum frame rate of 30 frames per second, and that the recommended cover size is 420 x 654 pixels, a 1:1.55 ratio (help.instagram.com/1038071743007909, checked September 2026). This guide turns those figures into an export setting, shows where the Reels interface covers the picture, and explains how to produce a reel from stills or a text description.
What is the Instagram Reels aspect ratio?
Instagram accepts reels from 1.91:1 (wide) to 9:16 (tall); 9:16 is the ratio that fills the screen in the Reels feed, so 1080 x 1920 is the size to export unless you deliberately want a smaller, letterboxed picture.
| Spec | Instagram's figure (checked Sept 2026) | Practical export |
|---|---|---|
| Aspect ratio | Between 1.91:1 and 9:16 | 9:16 for full screen |
| Minimum resolution | 720 pixels | 1080 x 1920 |
| Minimum frame rate | 30 fps | 30 fps, or 60 for fast motion |
| Cover photo | 420 x 654 recommended (1:1.55) | Export the cover at 1080 x 1683, the same ratio at higher resolution |
| Quality setting | "Upload at highest quality" toggle in Media quality settings | Turn it on; uploads take longer and look sharper |

The lower bound matters for repurposed content. A 16:9 clip (1.78:1) is inside the accepted range, so it uploads as a reel, but it appears as a letterboxed strip with the interface around it. A 4:5 clip (1080 x 1350) sits comfortably in the range and shows larger than 16:9 while still leaving room for the caption below. Full-screen impact needs 9:16.
Where does the Reels interface cover your video?
Instagram does not publish safe-zone coordinates, so this is tested practice: the bottom quarter carries the username, caption, audio label and any product tags; the right edge carries the like, comment, share and menu icons stacked vertically; the top carries the Reels title bar. Keep faces, product shots and on-screen text inside the middle 60% of the height and the left 75% of the width. Captions sit best just above the vertical midpoint. The aspect ratio resizer and safe-zone preview overlays the Reels interface on your own frame, at 9:16, 4:5, 1:1 and 16:9, so the crop is decided before the export rather than after the upload.
What is the Instagram Reel cover size?
Instagram recommends 420 x 654 pixels, a 1:1.55 ratio, and notes the cover cannot be changed after upload. Export the cover at that ratio but at higher resolution, 1080 x 1683, because it is downscaled cleanly and looks sharp on the profile grid. On the grid the cover is cropped to a 3:4 tile, and in the feed it may be cropped to a square, so keep the subject in the centre of the cover and any title text in the middle third of its height. The Instagram post size reference lists every placement's pixels and the grid's safe area.
How do you make a reel from photos or text?
- Set the ratio first. Generate or crop every asset at 9:16 before anything else; a horizontal image cropped to vertical afterwards loses two-thirds of its width. The crop image for video tool shows exactly what a 9:16 crop removes from a photo.
- Make the stills. The AI image generator renders at 9:16 directly; keep one style description across the set so the reel cuts together.
- Animate the beats that need motion. Image to video turns a still into a 9:16 clip of 4, 6, 8, 10 seconds in PrismPoster's Video Studio. A 15-second reel is two to four clips; a 60-second reel is an edit of several.
- Add the sound. Reels are watched with sound more than most feeds. A track generated to the reel's length from the AI music generator costs 25 credits and arrives with stems.
- Cut at 30 fps or 60 fps. Instagram's minimum is 30; 60 fps helps only for fast motion and doubles the file size.
- Export 1080 x 1920, H.264 MP4, and turn on "Upload at highest quality" in Instagram's media settings before uploading.
The composition rules that make a vertical frame work, including where to put a face and how to handle text, are in the vertical video guide; the generation-specific workflow is in the AI reels generator guide. The reel then also fits YouTube Shorts and TikTok without re-editing, because all three use the same 9:16 frame; only the overlay positions differ, which is why the safe-zone preview shows each platform separately.
What resolution and bitrate keep a reel sharp?
Export at 1080 x 1920 with a bitrate of roughly 8 to 12 Mbps for 30 fps H.264, higher for 60 fps. Instagram re-encodes every upload, so the goal is to give it a clean, high-bitrate source rather than a small file; a heavily compressed source gets compressed again and shows blocking in dark areas and gradients. The video bitrate calculator turns a target file size or a target quality into the bitrate to set.
Publishing on more than one platform? The sizing rules for other surfaces are in YouTube Shorts size and length, YouTube thumbnail size, YouTube banner size, Facebook cover photo size, and LinkedIn banner size.
Frequently Asked Questions
What size should an Instagram Reel be?
1080 x 1920 pixels at 9:16. Instagram accepts anything from 1.91:1 to 9:16 with at least 720 pixels of resolution and 30 fps, per its help page in September 2026, but only 9:16 fills the screen.
Can I upload a 16:9 video as a reel?
Yes; 16:9 (1.78:1) is inside Instagram's accepted 1.91:1 to 9:16 range. It plays as a letterboxed strip with the interface around it rather than full screen, so crop or pad it to 9:16 if you want the full frame.
What is the Instagram Reel cover photo size?
Instagram recommends 420 x 654 pixels (1:1.55). Export at 1080 x 1683 for a sharper result at the same ratio, keep the subject centred because the grid crops it to 3:4, and choose carefully, since the cover cannot be changed after upload.
How long can an Instagram Reel be?
Instagram's Reels size page does not state a maximum length as of September 2026. AI-generated reels are assembled from clips of 4, 6, 8, 10 seconds on a timeline, so the practical length is decided by the edit, not the generator.
