The best time to post Instagram Reels is when your followers are most active, which you can find in Instagram insights under "Most active times". Posting shortly before peak activity gives your Reel a strong start.
However, Reels can continue gaining views for days as Instagram tests them with new audiences. Content quality matters more than timing. Test different posting times and compare initial performance, then choose a consistent schedule.
Step-by-step plan
Check "Most active times" in insights.
Post shortly before peak activity.
Test different times for two weeks.
Compare initial and seven-day performance.
Choose a consistent schedule.
Example: a creator tests posting at 9 a.m. and 7 p.m. Evening Reels get 20% more views in the first day, but seven-day totals are similar, showing quality still matters most.
Why this works
Instagram has said its three most important ranking signals for Reels are watch time, likes per reach and sends per reach, with sends weighted heavily for reaching non-followers. Original content is favoured: Instagram reduces the reach of reposted clips and recycled videos carrying other apps' watermarks. Trial reels let you test a Reel on non-followers before your followers see it, which makes Instagram one of the easiest platforms to experiment on without hurting your profile.
Common mistake to avoid
Obsessing over posting time while neglecting content quality. Reels keep reaching new audiences for days, so the hook matters more than the hour.
Pro tip
Share each new Reel to your Story right after posting. It sends your most engaged followers to the Reel early, strengthening its first test.
