How it works
A Reel is a vertical video with sound that fills the screen. You record or upload clips, trim and arrange them, and can add music or original audio, text, captions and effects. Reels appear on your profile, in followers' feeds and in the Reels tab, where viewers swipe from one to the next.
What makes the format matter is how it is distributed. Instagram has said that most of what people see in Reels comes from accounts they do not follow, chosen by its recommendation system. That makes Reels the main way a small account can reach strangers. The signals Instagram says it weighs for Reels include whether viewers watch to the end, like, reshare and tap through to the audio.
Creators plan Reels around the first seconds, because a viewer decides almost at once whether to keep watching. A typical structure is a hook that states the payoff, the content itself, and one clear next step. Length limits and recommendation rules have changed several times. Check the sources on this page and Instagram's own pages before you plan long videos, and read your Insights to see where viewers stop watching.
A worked example
A fitness creator plans a 30-second Reel that teaches one stretch.
- Seconds 0 to 2: the hook, spoken and on screen. Fix tight hips with one stretch.
- Seconds 2 to 25: the stretch shown from two angles, with one common error to avoid.
- Seconds 25 to 30: a single next step. Save this for your next desk break.
- Two days later the retention graph in Insights shows a drop at second 12, where the second angle began. The next Reel makes that section shorter.

Common mistakes
- Opening slowly. Logos, greetings and long introductions lose viewers before the content starts.
- Treating a length limit from an old post as current. The limits have changed more than once.
- Judging a Reel by likes alone. Watch time and shares say more about whether it will be recommended.
- Putting text at the edges. The app's buttons and caption cover the bottom and the right side of the screen.
Questions people ask
How long can a Reel be?
The limits have changed several times. When this entry was reviewed, Instagram's own Reels page said that you can record and edit Reels of up to 20 minutes, and that Reels over 3 minutes are not recommended to new audiences. See the sources on this page.
What shape should a Reel be?
Vertical, in a 9:16 shape, which fills a phone screen. Keep important text away from the edges, where the interface covers it.
Do Reels get more reach than photos?
Reels are the format Instagram recommends most to people who do not follow you, so they tend to reach more strangers. There is no fixed multiplier. Compare formats in your own Insights.
