Instagram quietly rolled out a 20-minute upload ceiling for Reels in late 2025, finishing the rollout to all eligible accounts in February of this year. The change made it possible to publish long-form video on the same surface where short-form video has lived for the last five years. The catch is that Instagram's recommendation engine, which decides what gets pushed to people who do not already follow you, has not changed. Adam Mosseri confirmed in a creator Q&A on April 22 that videos longer than three minutes are not promoted to non-followers, full stop. The cap is not a soft suggestion. It is a hard line in the recommendation graph.
The practical implication is that creators now have two separate playbooks running on the same platform. The growth playbook still lives at 7 to 15 seconds for hook-driven content, where completion rates run between 78 and 91 percent according to Hootsuite's Q1 industry benchmark. Reels in that length range capture the largest share of the discovery surface and produce the highest follower-conversion rate per impression. Anything past 90 seconds shows a measurable drop in algorithmic reach, with median completion falling to 38 percent at the 60-second mark and 22 percent at the 90-second mark. By the time a Reel hits three minutes, fewer than 14 percent of viewers finish it and the algorithm reads that signal as a negative.
The retention playbook lives in the longer cuts. Once a creator has followers, longer Reels function the way an IGTV video used to before Instagram folded that surface into the Reels tab. A 6-to-10-minute Reel will get distributed to existing followers in the home feed, and the views that arrive convert at much higher rates because the audience is self-selected. Caraway, the cookware brand, ran a test in March publishing the same recipe demo as a 60-second Reel and a 9-minute Reel. The 60-second cut got 412,000 views and 47 link-in-bio clicks. The 9-minute cut got 38,000 views and 1,840 link-in-bio clicks. Different goals, different audiences, different metrics.
Mid-tier creators are running the split most aggressively. Justin Welsh's recent Instagram strategy thread in early April described his current cadence as three short Reels per week for top-of-funnel reach plus one long-form Reel per week for community, course sales, and newsletter conversion. Codie Sanchez has run a similar split since February. Brand-side, AG1, Athletic Greens' parent label, has shifted 22 percent of its short-form spend toward in-feed long-form Reels in Q1 after running a six-week test that found long-form click-through to landing pages outperformed short-form by 3.4 times when measured against new email subscriber cost.
Meta's overall video strategy across Instagram and Facebook has been pulling toward longer content for the last 18 months. Threads added video posts in late 2024, Facebook expanded long-form Reels first in early 2025, and Instagram followed last summer. The unifying logic is that YouTube and TikTok have both shown that long-form video drives session depth and ad inventory. Instagram's average session length has held at roughly 32 minutes per day per active user against TikTok's 47 minutes, and Mosseri's team has framed the long-form Reels push as a session-length play. Whether they get there depends on whether creators actually publish enough long-form content to fill the surface.
The data on what is actually working in Q1 reads as follows. Hootsuite's industry benchmark across 1.4 million Reels shows that the 7-to-15-second range delivers a median 8.7 percent engagement rate against 4.2 percent for the 60-second range and 2.1 percent for the 3-minute range. Reach to non-followers drops by approximately 47 percent for every additional minute beyond 30 seconds. Completion rate, which feeds the recommendation graph more heavily than likes or comments, falls fastest in the 30-to-90-second range. The implication for the algorithm is that a 90-second Reel needs roughly 3 times the absolute view count of a 15-second Reel to compete on the recommendation surface.
The vertical aspect ratio remains a non-negotiable. 9:16 vertical posts get 31 to 47 percent more reach than landscape or square video on the Reels surface, with the gap widest on stories that get reshared into the Reels tab. Captions, in-video text overlays in the first three seconds, and a clear hook frame are the three production elements with the largest measured impact on completion rate. Instagram's Edits app, the in-house competitor to CapCut that launched in February, has been pushing creators toward those production conventions through templates and an AI-assisted captioning tool that hits 96 percent transcription accuracy on first pass.
For the smaller creator without a paid budget, the prescription is simple. Three to five short hook-driven Reels per week for reach, one long-form Reel per week for the audience that already follows. Stop chasing the 20-minute ceiling expecting it to do what TikTok long-form does. Instagram has not built that infrastructure yet, and the algorithm punishes anyone who pretends otherwise.
