Best Instagram reel length: 7, 15, 30 or 90 seconds?

The best reel length is the shortest one that delivers your point. What Instagram cares about is how much of the reel people watch, so a 12-second reel watched to the end beats a 60-second reel abandoned halfway. Here is how to choose a length for the kind of content you make.

Length	Good for	Watch out for
7–15 seconds	Jokes, transitions, product reveals, loops	Too short to teach anything
15–30 seconds	Quick tips, recipes, outfit ideas, before-afters	Padding in the middle
30–60 seconds	Step-by-step tutorials, stories, comparisons	Needs a reason to stay
60–90 seconds	Deeper explainers when retention is already strong	Big drop-offs after 20 seconds

Rules that help

• Trim until every second earns its place. Remove “ummm”, intros and silent gaps.
• If a reel is longer than 30 seconds, add a reason to stay: a countdown, a reveal at the end, a list of numbered tips.
• Loops, where the end flows into the start, encourage replays and improve watch time.
• Match the length to the idea. A single tip does not need 60 seconds.

Test it yourself

Post three reels of different lengths on the same topic over a week. Open Insights and compare average watch time and the percentage watched. Your own audience’s answer beats any rule.

If most people leave in the first three seconds, fix the hook, not the length. If they leave at the halfway point, cut the middle. Our guide to making reels that travel covers hooks in detail.
