How long should a reel be in 2026? Shorter than you think

Every quarter someone asks us this in a kickoff call, so here is the current answer with the numbers behind it.

The 11 second median

Across the last 150 client reels, the median top-quartile performer ran 11 seconds. Under 15 seconds, completion rates sit above 70%. Past 30 seconds they drop under 40% for accounts below 50K followers. The algorithm rewards completion, so the short cut wins the distribution war even when the long cut is better made.

When longer wins

Three cases where we still go long: tutorials where the steps need room, story content where the payoff is the ending, and anything aimed at an audience over 45, who will actually watch a 60-second video about a product they care about. The rule we use: one idea under 15 seconds, a real story under 60, and nothing ever crosses 90.

The loop trick

Our best reels end where they started. Cut the last frame so it flows into the first and the loop counts as a replay, which inflates watch time, which buys reach. About a third of our top performers use a looped ending. Free distribution, no ad spend.

How to test it yourself

Take one idea, cut it at 10 seconds and at 35. Post them a week apart at the same time of day. Read completion rate, not views, views lie. That is exactly what we run for retainer clients in month one before locking a format. The hooks post covers what to put in the first two seconds once the length is sorted.

Completion rate is the metric. Views are just the applause it buys.
