How long should a reel be? My reels past 1M ran 78 to 107 s
Length against views for 57 of my reels, Instagram's 20-minute limit and its 3-minute line for reach, and why the script should set the length.
Make a reel as long as its idea needs, and keep it under 3 minutes. Instagram lets you post reels up to 20 minutes, but its help page says reels over 3 minutes won't be recommended to new audiences (read Nov 1, 2026). On my account, all five reels that passed 1M views ran 78 to 107 seconds, while my 7 to 10 second clips never reached 50K (Instagram API, Nov 1). They are animated explainers written by Claude Code, and each one lasts as long as its script.
- The limit: 20 minutes to post, 3 minutes to be shown to people who don't follow you.
- My numbers: every reel past 1M ran 78 to 107 s. Reels of 110 to 153 s had the best median, 134K.
- Not a rule: it's one account, and the length changed together with the format. Reels of the same length also stalled.
- Let the script decide: one question, answered all the way, then stop. The seconds follow.
How long should a reel be to go viral? 57 of my posts by length
On my account, every reel that passed 1M views ran between 78 and 107 seconds. The chart puts all 57 posts with a known length side by side, from 7-second tool clips in August to 153-second explainers in October.
All five are animated explainers that Claude Code wrote as code and rendered to MP4 with Full Visual, a folder for Claude Code and Codex. Each one lasts as long as the voice reading its script.
Do longer reels get more views? Not on their own
Length alone didn't do it. The same 78 to 107 second range holds my two biggest reels and six that stalled under 5,000 views.
The bigger catch: length and format changed on the same day. Until Sep 23 I posted short tool clips, a demo on top and my face at the bottom. From Sep 28 I posted full-screen explainers, most of them 78 to 153 seconds. The chart can't separate the two. My read: the explainers needed the seconds, the seconds didn't make the explainers.

The 17 to 38 second row is mostly comment-for-a-link posts, a different kind of reel. A big benchmark points somewhere else again: Socialinsider looked at 9.77M reels from brands with 1K to 1M followers (Jan to Jun 2026) and found 45 to 60 seconds had the highest median views, 10,374, and reels over 3 minutes the lowest, 4,428. Two data sets, two answers. The subject and the script move views more than the seconds do.
Nobody has to finish, either. The five reels past 1M were watched for 30 to 38 seconds on average, under half their length (API, Nov 1). What that number means and what good looks like: average watch time on Instagram reels.
How long can a reel be on Instagram in 2026?
Up to 20 minutes. Instagram's help page says "You can record and edit videos up to 20 minutes with Instagram Reels", then adds the line that matters: "Reels over 3 minutes won't be recommended to new audiences" (read Nov 1, 2026). For reach, the limit is 3 minutes.
That line dates from January 2025. Before it, reels topped out at 90 seconds. Adam Mosseri, head of Instagram, on Jan 18, 2025: "We've historically only allowed reels up to 90 seconds given our focus on short-form video, but we've heard the feedback that this is just too short for those who want to share longer stories." A guide that still says 90 seconds is out of date.

Past 2 minutes and still under 3: both reels passed 350K views.
Go deeper: 90-minute videos, and why guides quote other limits
On Oct 26, 2026 Instagram began testing Features, horizontal videos of up to 90 minutes for select creators in the US, with reels that link to the full video (The Hollywood Reporter). That's a separate format, not a longer reel. Other guides quote 15 minutes for uploads or 90 seconds for recommendations; Instagram's own page said 20 minutes and 3 minutes when I read it on Nov 1, 2026. The same page notes reels aren't available to every account yet.
Let the script set the length, not a target
Write the script first and let the seconds fall out of it: one question, answered all the way, then stop. The keyboard took 78 seconds, PS5 on a PC took 107. Different subjects, different scripts.
That's how my reels get their length. Claude Code writes the script to fit the subject, a voice reads it, and every scene is drawn to the voice, so the reel runs as long as the explanation does. How these reels are made, layer by layer: how people make those Claude reels.

Four checks on length before you post:
- Under 3 minutes, or new viewers won't be shown it.
- The question in the first line. A long reel only gets watched if the opening holds. Mine, word for word: 7 opening lines that got 110K to 13M views.
- Cut what the answer survives without. Read the script out loud and drop any sentence nobody would miss.
- Keep the picture moving with the words. Eighty seconds of one still frame is a long wait.

Questions
How long can a reel be on Instagram?
Up to 20 minutes, per Instagram's help page (Nov 1, 2026). Reels over 3 minutes won't be recommended to new audiences, so 3 minutes is the practical limit for reach.
What is the best length for Instagram reels in 2026?
There isn't one. A benchmark of 9.77M brand reels found 45 to 60 seconds best; my five reels past 1M ran 78 to 107. Use the shortest length that fully answers the question.
How many seconds should a reel be to go viral?
Length won't make a reel go viral by itself. On my account, reels from 17 to 153 seconds passed 100K views, and reels of the same lengths also stalled.
Are reels over 90 seconds still pushed less?
Not since January 2025, when Instagram moved from 90 seconds to 3 minutes. Its help page now names 3 minutes as the line for recommendations to new audiences.
Can Claude Code make a reel the right length?
It writes the script for the subject and renders the reel to the length of the voice reading it. My explainers are made that way with Full Visual, a folder for Claude Code and Codex.
