The short answer
Make Instagram Reels at 1080 x 1920 pixels, a 9:16 vertical aspect ratio, at 30 frames per second or more, exported as an MP4. That fills the full phone screen in the Reels tab and is the size Instagram displays on most devices.
Below is every spec you are likely to need, what Instagram does with other shapes, and how covers, the profile grid and the safe zone fit in.

Why 9:16 is the right aspect ratio
A phone held upright is roughly 9:16 or taller. A 9:16 reel uses the whole screen in the Reels tab, so nothing else competes with your video. Anything wider leaves empty space above and below.
Instagram's Help Center says reels can be uploaded at aspect ratios between 1.91:1 (wide landscape) and 9:16. So a square or horizontal video will upload, but it plays as a smaller box in a vertical screen. For a reel, that wasted space usually costs attention.
If your source footage is horizontal, crop it to 9:16 in your editor and reframe each clip so the subject stays in view, or place it over a blurred copy of itself so the frame is filled. Both look better than letterboxing.
Resolution: 1080p, 1440p or 4K?
1080 x 1920 is the practical standard for organic reels. It is sharp on phone screens, uploads quickly, and leaves Instagram less to compress. Instagram's Help Center sets 720 pixels as the minimum resolution, which is fine for a quick share but noticeably softer.
Meta's ad guide lists 1440 x 2560 as the recommended resolution for Reels ads. If you are running ads, or your footage is high quality and you want a little extra headroom, exporting at 1440p is reasonable. Exporting 4K for a reel rarely helps: the file is several times bigger and the result on a phone looks the same after compression.
| Export | Pixels (9:16) | When to use |
|---|---|---|
| 720p | 720 x 1280 | Minimum; quick drafts or very slow connections |
| 1080p | 1080 x 1920 | Default for organic reels |
| 1440p | 1440 x 2560 | Reels ads, or extra headroom on high-quality footage |
Frame rate and file format
Instagram's Help Center gives 30 FPS as the minimum frame rate for reels. Shoot and export at 30 FPS for most content. If you shot at 60 FPS for smoother motion, exporting at 60 is fine, but don't convert 24 or 30 FPS footage up to 60; it adds file size without adding smoothness.
Export as MP4 with H.264 video and AAC audio. Meta's ad spec also suggests a fixed frame rate and AAC stereo audio at 128 kbps or higher, which is a sensible target for any reel. Avoid variable frame rate exports from screen recorders where you can, since they sometimes cause audio drift after upload.
File size and length limits
Meta's Reels ad spec caps files at 4 GB. A 1080p reel of a minute or two at a normal bitrate is usually far smaller, often well under 100 MB, so file size is rarely the limit you hit.
Length is more relevant. Instagram's help page on recording reels says you can record and edit reels up to 20 minutes, and that reels over 3 minutes won't be recommended to people who don't follow you. Upload limits can vary by account and roll out gradually, so if the app trims your video, check the length selector before you assume something is broken.
Reel cover size and the profile grid
Your cover is the still image that represents the reel on your profile and in some feeds. Instagram's Help Center recommends a cover of 420 x 654 pixels, a 1:1.55 ratio. In practice, most creators design the cover at the full 1080 x 1920 so it also works full screen, then keep the important part in the middle.
In January 2025 Instagram switched profiles from a square grid to a taller rectangular grid, which press coverage at the time described as 3:4. That means a 9:16 cover is trimmed at the top and bottom in the grid. Put the face, product or title in the vertical centre of the image and keep a margin on every side.
- Design the cover at 1080 x 1920
- Keep the title and subject inside the central 1080 x 1440 area
- Use large, short text: the grid thumbnail is small
- Check the crop in the cover editor before you post
Safe zones: the part of the frame you can trust
The full 1080 x 1920 frame is visible, but Instagram's interface sits on top of it: your username, caption and audio label at the bottom, and the like, comment and share buttons down the right side. Text placed there can be covered.
Meta's ad guidance for Reels says to keep roughly 14% of the top, 35% of the bottom and 6% of each side free of text and logos. On a 1080 x 1920 frame that works out to about 270 px at the top, 670 px at the bottom and 65 px on each side. Organic reels show a lighter overlay than ads, so that is a conservative margin, which is why it is a good default.
Other Instagram formats and how they relate
If you want one edit to work in several places, it helps to know the other common shapes. A 9:16 reel can also run as a Story. Feed posts are often 4:5 or 3:4, and some older content is 1:1. If you keep the main action in the centre of a 9:16 frame, a 4:5 crop of the same video usually still works.
| Format | Aspect ratio | Pixels |
|---|---|---|
| Reel / Story | 9:16 | 1080 x 1920 |
| Tall feed post | 4:5 | 1080 x 1350 |
| Grid-shaped post | 3:4 | 1080 x 1440 |
| Square post | 1:1 | 1080 x 1080 |
| Landscape | 16:9 (or up to 1.91:1) | 1920 x 1080 |
How to set the right size before you edit
Pick the canvas first, then add clips. If you start a project in 16:9 and switch at the end, every clip has to be reframed again. In most editors this is a project setting called format, canvas or aspect ratio.
Shoot vertical when you can. Phone cameras hold the subject in frame naturally in portrait, and you avoid throwing away two-thirds of a landscape frame when you crop. For photos, portrait shots crop to 9:16 far better than landscape ones.
- Set the project to 9:16 before importing
- Shoot in portrait at 1080p or higher, 30 FPS
- Reframe any horizontal clips so faces stay centred
- Export 1080 x 1920 MP4 and check it on a phone
Common size problems and fixes
| Problem | Likely cause | Fix |
|---|---|---|
| Black bars above and below | Video exported in 16:9 or 1:1 | Re-export in 9:16, reframing clips |
| Edges cut off | Video slightly wider than 9:16 | Use an exact 1080 x 1920 canvas |
| Soft or blurry result | Source under 720p, or heavy digital zoom | Use higher-resolution source and export 1080p |
| Text hidden by buttons | Text placed near the bottom or right edge | Move text into the safe zone |
| Cover cropped badly in grid | Title near the top or bottom of the cover | Centre the title in a 3:4 area |

Frequently asked questions
What size is an Instagram reel in pixels?
+
The standard Instagram reel size is 1080 x 1920 pixels, which is a 9:16 vertical aspect ratio. Meta's ad spec also lists 1440 x 2560 for Reels ads.
Can I post a horizontal video as a reel?
+
Yes. Instagram supports aspect ratios from 1.91:1 to 9:16 for reels, but a horizontal video plays as a smaller box with empty space. Cropping to 9:16 usually looks better.
What is the Instagram reel cover size?
+
Instagram's Help Center recommends 420 x 654 pixels (1:1.55). Many creators design covers at 1080 x 1920 and keep the subject and title in the centre so the grid crop doesn't cut them.
Is 4K better for Instagram reels?
+
Usually not. Instagram compresses uploads for phone screens, so 1080p looks nearly identical and uploads much faster. 1440p is a reasonable step up if you want extra headroom.
What frame rate should Instagram reels be?
+
Instagram lists 30 FPS as the minimum. Export at 30 FPS for most content, or 60 FPS if you shot at 60 for smooth motion.
