If you search for the best time to post on Instagram Reels, you'll find three big studies, and they give you three different answers. Later says midnight on Monday. SocialPilot says weekday mornings between 8am and noon. Hopper HQ says Tuesday and Wednesday, 7 to 9am Eastern.
They can't all be right. I'll show you what each one found and why they disagree, and then I'll tell you what I actually tell customers when they ask me this, which is that posting time barely matters next to two other things you control. If you only read one section, read the one called "What actually decides whether a Reel gets seen."
Best Time to Post on Instagram Reels, According to Three Studies
| Study | Data | Best time for Reels | Best days |
|---|---|---|---|
| Later | Over 6 million feed posts including roughly 975,000 Reels, January to October 2024 | 12am Monday, strong from 12am to 6am | Monday |
| SocialPilot | 250,000 Reels from 30,000+ accounts, published December 2025 | 8am to 12pm | Monday through Thursday |
| Hopper HQ | Their own customers' engagement data plus public studies, published June 2026, no dataset size given | 7 to 9am Eastern | Tuesday and Wednesday |
Later: post before dawn
Later's analysis is the largest, and its headline finding is the strangest. Across the whole dataset, posts published between 3am and 6am got higher-than-average engagement, with 5am as the single best hour. For Reels specifically, 12am on Monday came out on top, with strong results anywhere between midnight and 6am.
Later's own explanation is worth quoting, because it's more honest than most: "being consistent and creating engaging content is important too, if your posts don't resonate, your posting time won't make much of a difference." Their takeaway line is "consistency matters more than perfection." Keep that in your pocket.
SocialPilot: weekday mornings
SocialPilot looked at a quarter of a million Reels and found peak engagement Monday through Thursday between 8am and noon. Their per-day breakdown has Tuesday at 8, 9 and 10am, Wednesday at 9am, 11am and 1pm, Thursday at 6am, 11am and 12pm. Weekends were weaker across the board.
Their caveat is also useful: these times "work great when targeting users across multiple regions from a single account," and results vary a lot by geography, industry and audience. In other words, this is the answer for an account that has no idea where its audience lives.
Hopper HQ: Tuesday and Wednesday, early
Hopper HQ's guide is the most recent and the least transparent about its data. It leans on their own customers plus public research and lands on three daily windows: 6 to 9am, 11am to 1pm, and 7 to 9pm Eastern, with Wednesday 7 to 9am as the single peak. For Reels, they say Tuesday or Wednesday 7 to 9am "consistently drives the strongest early engagement," and they note that Reels have "a longer distribution tail than Feed posts," which matters more than the times do.
Why the Three Studies Disagree
None of these teams is lying. They're measuring different things.
Time zones. Later's "5am" is an average across accounts in every time zone on earth. For any one creator, that number means almost nothing. Hopper reports in Eastern time. SocialPilot doesn't say. When one study says midnight and another says 8am, part of the gap is just that they're not measuring the same clock.
Different accounts. SocialPilot's users skew toward agencies and businesses. Later's include a lot of creators and brands. Hopper's are Hopper's. A study of business accounts will find business hours. A study of creators will find whenever creators post.
Different windows. Later's data ends in October 2024. SocialPilot's came out December 2025. Hopper's is from June 2026. Instagram changed how Reels get distributed in that stretch, so a two-year-old finding about "best time" may be describing an algorithm that no longer exists.
Reels don't work like feed posts. This is the big one. A feed post lives or dies in its first few hours, mostly with your followers. A Reel gets tested on small batches of non-followers over days. Hopper's "longer distribution tail" is the polite version of: the algorithm will find your Reel an audience whenever you post it, if the Reel is good.
What Actually Decides Whether a Reel Gets Seen
When a customer asks me the best time to post a Reel, I tell them it barely matters. Not "it doesn't matter at all." Barely. Next to the two things below, it's a rounding error, and I've watched people spend more energy on scheduling than on the video.
The first second. A Reel gets shown to a small group of people who don't follow you. If they swipe in the first second, it stops there. If they stay, it gets shown to more. Nothing about 8am versus 8pm changes what happens in that first second. The hook does. If you don't have a hook, you have a Reel that gets shown to 200 people at the perfect time and then dies.
Consistency. Every one of the three studies above says some version of this in the fine print, and it's the part people skip. An account that posts three Reels a week at the "wrong" time will outgrow an account that posts one perfect-timed Reel a month, every time. Consistency is also what generates the only timing data that's about you, which I'll get to.
Watch time, shares and saves come after those two. If people watch to the end and send it to someone, Instagram keeps distributing it. That's a content problem, not a calendar problem.
The Only Schedule That Works
Pick a slot you can actually keep, and keep it.
If you need a default and you have no data of your own, weekday mornings are the one window all three studies overlap on, so start there. I post my own Reels in the evening, and the evening slot I keep beats the morning slot I'd miss. The best time to post is the time you'll post.
Then hold it for at least eight Reels before you judge it. One Reel at 7am tells you nothing. Eight of them, over a month, start to tell you something. If you change the slot every week, you'll never learn anything, because you'll never have two Reels posted under the same conditions.
And whatever the slot is, make it a habit that doesn't depend on motivation. The people who post consistently aren't more disciplined. They batch. They record a week or a month of videos in one sitting and schedule them, so posting Tuesday morning doesn't require being creative Tuesday morning. I wrote up how to batch record a week of videos in one sitting, and everything in it applies to Reels.
How to Read Your Own Insights in Five Minutes
Your account has better data than any of the three studies, because it's about your audience. Here's how to use it without turning it into a hobby.
1. Find when your followers are online. Open your profile, tap the Professional dashboard, then Insights, then Total followers, and scroll to Most active times. It shows hours and days. That's your audience's clock, not a global average.
2. Look at your last eight Reels. Note the posting time and the reach for each. If the reach is all over the place, the time isn't the variable. The hook is. If the morning ones are consistently ahead, you've learned something real.
3. Pick one slot for the next month. Not two. Not "I'll alternate." One. Then look again in four weeks.
4. Ignore day-of-week advice unless you see it in your own numbers. "Don't post on weekends" is true for an agency posting to businesses and false for a fitness creator whose audience is off work. Your Insights know which one you are.
That's it. Five minutes, once a month. Anything more than that is time you should have spent recording.
Where the Time Actually Goes
If you're reading timing studies, I'd bet the real bottleneck isn't when you post. It's that making a Reel still takes an hour, so you don't make enough of them to be consistent, so timing feels like the lever you can pull. It isn't. Volume is.
That's the problem CreateSocial is built to fix. Ideas come from a knowledge base built on your own website, past content and the competitors you watch, so you're not staring at a blank page. You record with the script scrolling above the camera, in sections, in the browser or on the iPhone app. Subtitles and captions for TikTok, Instagram, YouTube, LinkedIn, Facebook and X are written from what you said. Then you drag the whole batch onto the calendar, where the Best Times mode suggests a morning, midday, afternoon or evening slot for each day, and one video with six captions schedules as a single action. We don't auto-publish. When a post is due, you get a link on your phone and post from your own account. One recording also repurposes into a LinkedIn post, an X thread or a blog post, so the week's content comes from one sitting.
We did the same exercise for the other two platforms: best time to post on TikTok, where the data is much more consistent, and best time to post on YouTube, where it matters even less than it does here.
Bottom Line
The best time to post on Instagram Reels, according to the three biggest studies, is midnight Monday, or weekday mornings, or Tuesday at 7am, depending on who you ask. The honest answer is that they're measuring different audiences on different clocks, and Reels get distributed over days anyway.
What moves a Reel is the first second and whether you show up again next week. Pick a slot you can keep, hold it for eight Reels, check your own Insights once a month, and put the rest of that energy into making more videos. If the making is the slow part, that's what we fix.
