How Long Should a Reel Be?
A Reel can run up to 20 minutes, but past 3 minutes Instagram won't recommend it to non-followers. The official limits and the right length for your goal.
By the Oposto team · · Social platforms
If you want a Reel shown to new people, keep it at 3 minutes or less. Instagram lets you record up to 20 minutes, but says Reels over 3 minutes won't be recommended to people who don't follow you. Under that ceiling, the right length is the shortest one that says everything you need to say.
These limits are current as of late September 2026 and they change often. For every format and platform rule, our Instagram guide to formats and best practices keeps them up to date.
What are the official length limits?
On its official Reels page, Instagram says you can record one or more clips adding up to 20 minutes, and that Reels over 3 minutes won't be recommended to new audiences. The creator FAQ backs this up: Instagram recommends videos of 3 minutes or less to unconnected audiences.
| Situation | Limit | Source |
|---|---|---|
| Reel recorded in the app | Up to 20 minutes | Instagram Reels page |
| Recommended to non-followers | 3 minutes max | Reels page and creator FAQ |
| Reel published through a tool (API) | 3 seconds to 15 minutes | Instagram API documentation |
The upshot: a 5-minute Reel will mostly be seen by your existing followers. If your goal is discovery, stay under 3 minutes.
Is shorter always better?
No. Instagram doesn't publish an ideal length, and there's no official "15 seconds is best" figure. What the platform does describe, in Instagram Ranking Explained, are the signals it predicts for Reels: how likely you are to share it, watch it all the way through, like it, or go to its audio page.
Watching to the end is easier on a short video, but a short, empty video won't get shared or saved. So the real question isn't "how many seconds?" but "what's the minimum length that delivers on my promise?" Every second that adds nothing is a chance for someone to swipe away.
Not too short, not too long
What a short video makes easier
- Being watched to the end
- Being rewatched on loop
What it still has to deliver
- A reason to share it
- A reason to save it
- The promise of the hook, kept
How long should your Reel be for your goal?
These are not norms published by Instagram: they're starting points to check against your own analytics.
| Goal | Starting length | Why |
|---|---|---|
| Show a product, a technique, a result | A few seconds to 30 seconds | One idea, easy to rewatch on loop. |
| Give a tip, answer a question | 30 seconds to 90 seconds | Enough time to set up the problem and answer it, no detours. |
| Walk through a method or tutorial | 1 to 3 minutes | Several steps, still under the recommendation ceiling. |
| Talk to your followers (live recap, long form) | Over 3 minutes | Fine when your existing audience is the target, not discovery. |
How do you cut a Reel down without losing the message?
- Start with the ending. Show the result, the question or the problem in the first second, no intro. Our 30 hooks by platform and format give you templates.
- One video, one idea. If you have three tips, make three Reels or a carousel.
- Cut the dead air. Pauses between sentences, "so, um," the hello at the top: anything that delays the information.
- Let the speaker finish. If someone is talking, don't chop a sentence to hit a timer: trim the script before you film. A teleprompter helps a lot, as we explain in filming yourself without memorizing a script.
- Add captions. Some of your audience watches with the sound off; on-screen text lets them follow along anyway.
If you'd rather not be on camera, length works the same way with hands, a product or a voiceover: see our 15 Reel ideas without showing your face.
What about Facebook, TikTok and YouTube?
- Facebook: since June 2025, Meta has said on its official blog that all videos are shared as Reels, with no length limit in the app. Through the publishing API, though, a Facebook Reel has to run 3 to 90 seconds.
- YouTube: a square or vertical video of 3 minutes or less is classified as a Short, per YouTube Help.
- TikTok: TikTok Help lists up to 10 minutes for a video recorded in the app and 60 minutes for an uploaded one.
So a vertical Reel under 90 seconds is the format that travels most easily from one platform to the next.
The ceiling that matters, platform by platform
- 3 min Instagram: beyond that, a Reel isn't recommended to non-followers
- 3 min YouTube: a square or vertical video up to 3 minutes is a Short
- 90 s Facebook: maximum length of a Reel published through the API
- 10 min TikTok: video recorded in the app (60 minutes if uploaded)
How do you find your ideal length?
In each Reel's Instagram insights, look at watch time, shares and saves. Compare your Reels against each other over a month: if your long ones get abandoned early, go shorter; if your short ones get no saves, they may lack substance. Change one thing at a time and give each test several posts before you judge it. And take care of the rest too: a clear topic plus a few specific hashtags help Instagram find the right viewers, as we explain in hashtags: how many, which ones and where.
