Instagram Reels length and format affect reach and completion rate. In 2026 you can upload Reels up to 90 seconds (or longer in some regions). Shorter often holds attention better; 15–30 seconds is a sweet spot for many. Here’s what to know and how to plan Reels content from one workflow.
How long can Reels be?
Reels can be from a few seconds up to 90 seconds (and in some cases longer). Instagram may extend limits over time; check the app for current caps. For most accounts, 15–30 seconds keeps viewers to the end, which helps the algorithm. Use 9:16 aspect ratio (1080×1920) so they look right in feed and Explore.
Best practices for Reels in 2026
Hook in the first 1–2 seconds. Use text overlay or captions so people watching without sound still get the message. Add a clear CTA or end frame. Plan Reels themes and captions in one place—e.g. Athenous Lab for caption ideas and Post to schedule so Reels go out with the rest of your Instagram content.
Fit Reels into your calendar
When you schedule feed posts and Reels from the same calendar, you can balance frequency and avoid clumping. Create the Reel in Instagram or your editor, then schedule the publish time in Post alongside your other channels.
