The right Instagram Reel size is 1080 x 1920 pixels, which is a vertical 9:16 aspect ratio. A Reel at that size fills the phone screen edge to edge in the Reels tab, with no black bars and nothing cropped off.
Instagram will accept other shapes. Its help center says you can upload a Reel with any aspect ratio between 1.91:1 and 9:16, with a minimum frame rate of 30 FPS and a minimum resolution of 720 pixels. But anything that isn't 9:16 plays smaller than the screen, and anything narrower than 1080 pixels looks softer once Instagram compresses it.
Below is the full spec sheet: cover size, the 3:4 profile grid crop, safe zones for on-screen text, export settings and length limits. The specs were checked against Instagram's help center, Meta's developer documentation and Instagram's own announcements as of October 2026.

Why the right Reel size matters
Reels are the format Instagram uses most to show your content to people who don't follow you yet. They appear in the Reels tab, in Explore and in the main feed. That reach only pays off if the video looks like it belongs when it lands on someone's screen.
A Reel exported at the wrong size sends a quiet signal that it was made for somewhere else. Black bars, a soft image or a headline hidden behind the like button all give viewers a reason to swipe. The right size won't rescue a weak idea, but it removes an easy reason for people to leave in the first second.
It also saves you rework. Once you set up a 1080 x 1920 export preset, the same file works for Instagram Reels, Stories, TikTok and YouTube Shorts.
Aspect ratio and dimensions, explained
Aspect ratio is the shape of the frame. Dimensions are how many pixels fit inside that shape. A 9:16 video can be 720 x 1280 or 1080 x 1920. Both are the same shape, but the second carries more than twice as many pixels, so it keeps more detail after compression.
From aspect ratio to pixel dimensions
- 1080 x 1920 (9:16): the standard. Full screen, sharp, and the size Instagram's interface is designed around.
- 720 x 1280 (9:16): meets Instagram's 720-pixel minimum, but small text and fine textures turn mushy.
- 2160 x 3840 (9:16, 4K): uploads fine, but it's a much larger file and Instagram scales it down for playback. Only worth it if your editing workflow already runs in 4K.
What happens when the shape is wrong
Any Reel between 1.91:1 and 9:16 will upload. It just won't fill the screen:
- 16:9 landscape video plays as a thin band across the middle, with empty space above and below.
- 1:1 square video leaves wide bands at the top and bottom.
- 4:5 portrait gets closer, but still leaves gaps on a tall phone screen.
If you start with horizontal footage, reframe it to 9:16 in your editor before you upload. Zooming in inside Instagram's editor crops the edges and enlarges the pixels, which costs you sharpness.
How your Reel appears in different parts of the app
- Reels tab and full-screen view: the whole 9:16 frame.
- Profile grid: a 3:4 crop from the center of your cover image.
- Feed and Explore previews: can show a cropped version of the frame, so keep your subject near the middle.
Instagram Reel safe zones
Instagram draws its interface on top of your video. Your username, caption and audio label sit along the bottom. The like, comment, share and menu buttons stack down the right side. Anything you place in those areas can be covered.
Safe zone in pixels
Meta publishes margins for Reels ads, and they work well as a guide for regular Reels too. On a 1080 x 1920 frame:
- Top: keep about 14%, or roughly 270 px, free of text.
- Bottom: keep about 35%, or roughly 670 px, free of text.
- Sides: keep about 6%, or roughly 65 px, free on each side.
That leaves a central area of about 950 x 980 px for headlines, subtitles and logos. Ads add a call-to-action button at the bottom, so these margins are on the cautious side for organic Reels. Even so, keep anything important out of the bottom-right corner, where the caption and the button column overlap.
Check the preview before you post
Play the Reel on Instagram's preview screen before you share it. If a word in your on-screen text sits under the caption or the share button, move it up. Fixing it takes seconds. Reposting later costs you the views the first version already collected.
Export settings for a sharp upload
Instagram re-compresses every Reel it receives. You can't switch that off, but you can hand it a clean file so less detail is lost along the way.
File format and codecs
Export an MP4 (MOV also works) with H.264 video and AAC audio. Meta's developer documentation lists HEVC (H.265) as supported too, but H.264 is the most compatible choice across editing apps, phones and scheduling tools.
Frame rate and bitrate
Instagram's help center recommends a minimum of 30 FPS, and Meta's publishing API accepts anything from 23 to 60 FPS. Export at the same frame rate you filmed at, because converting 24 FPS footage to 30 FPS can add stutter. Meta's API caps Reel bitrate at 25 Mbps, so exporting above that only makes the file bigger without adding quality.
Length and file size
- Standard length: Instagram raised the Reel limit from 90 seconds to 3 minutes in January 2025.
- Longer Reels: uploads of up to 20 minutes started rolling out in late 2025. Instagram still recommends staying under 3 minutes, because longer Reels get limited distribution to people who don't follow you.
- Minimum length: 3 seconds, according to Meta's API specs.
- File size: Instagram doesn't publish an in-app cap. Tools that publish through Meta's API, including schedulers, are limited to 300 MB and 15 minutes per Reel.
For reference, a 60-second 1080 x 1920 export at 8 to 15 Mbps comes out at roughly 60 to 115 MB, well inside the API limit.
Reel cover size and the 3:4 profile grid
In January 2025, Instagram switched profile grids from squares to taller 3:4 rectangles. Your Reel cover now appears in the grid as a 3:4 crop taken from the middle of the image.
Instagram's help center lists 420 x 654 px as the recommended cover size. In practice, design your cover at 1080 x 1920 so it matches the video and stays crisp when someone opens the Reel full screen. Then keep the title and any faces inside the center 1080 x 1440 area. That's the part the grid shows. The top and bottom 240 px are trimmed.
Instagram's help center also says the cover can't be edited after upload, so set it before you tap Share. If you're building a cover from a photo, our free Instagram photo resizer helps you fit images to Instagram's sizes before you start designing.
Schedule your Reels with ViralFarm
Once your Reel is exported at 1080 x 1920, ViralFarm lets you schedule it to Instagram as a regular Reel or as a trial reel from one queue and calendar view. The same file can go to TikTok and YouTube Shorts in the same session, with a different caption for each channel.
If you're short on ideas, ViralFarm can also generate carousel slideshows from a link, a topic or pasted text, using templates modeled on posts that went viral. The free plan covers 2 channels and 20 published posts a month, with no credit card.
How Reel quality affects reach
Instagram has said that Reels ranking leans on how people respond: whether they keep watching, like and share. A crisp, full-frame video doesn't guarantee any of that. A soft or letterboxed one gives viewers an easy reason to keep scrolling.
Turn on highest-quality uploads
Instagram can lower upload quality to save data. To make sure it doesn't:
- Go to your profile and tap the menu icon in the top right.
- Under Your app and media, tap Media quality.
- Turn on Upload at highest quality.
- On the same screen, make sure Use less cellular data is off.
Menu labels shift between app versions and between iPhone and Android. If you don't see these exact names, type "media quality" into the search bar at the top of your settings.
Upload on a strong connection
Uploading over weak mobile data is one of the most common reasons a Reel looks worse than the file on your phone. Use Wi-Fi when you can. If a Reel still looks soft after that, our guide on why Instagram Stories look blurry covers the other causes, and the same fixes apply to Reels.
Frequently asked questions
Is the Instagram Reel size the same as the Story size?
Yes. Both are 1080 x 1920 pixels at 9:16. The difference is the overlay. Stories put the progress bar and your name at the top and a reply bar at the bottom, while Reels put the caption and buttons along the bottom and right side. Keep text in the center and one video works in both places.
What is the best quality setting for Instagram Reels?
Export at 1080 x 1920 as an MP4 with H.264 video and AAC audio, at 30 FPS and a bitrate under Meta's 25 Mbps cap. Then turn on Upload at highest quality in Instagram's Media quality settings and upload over Wi-Fi.
Can I post a 16:9 horizontal video as a Reel?
You can, since Instagram accepts ratios from 1.91:1 to 9:16. The video will play as a band across the middle of the screen, though, so it competes poorly with full-screen Reels. Reframe it to 9:16, or place it inside a vertical frame with a headline above and subtitles below.
What size is the Reel cover on my profile grid?
The grid shows a 3:4 crop from the center of your cover. On a 1080 x 1920 cover, that's the middle 1080 x 1440 pixels. Keep titles and faces inside that area.
How long can an Instagram Reel be?
Three minutes is the standard limit and the length Instagram recommends for reach. Uploads of up to 20 minutes have been rolling out since late 2025, but those longer Reels get limited distribution to non-followers. Scheduling tools that publish through Meta's API can post Reels of up to 15 minutes.
What's the minimum resolution for a Reel?
Instagram's help center lists 720 pixels as the minimum. Treat that as a floor, not a target. A Reel that's 1080 pixels wide holds up much better after compression.
