Best time to post on Instagram

The week, by how many studies agree

Each cell is one hour. The darker it is, the more of the 4 studies we plot name that hour for Instagram. It counts agreement between studies, not engagement - these samples measured different things and cannot be averaged.

What is specific to Instagram

• Instagram ranks the feed rather than ordering it by clock, so posting time works through early engagement rather than through who happens to be scrolling. Buffer puts it plainly: timing "isn't as critical as it was in the chronological-feed days" but "still plays a role".
• Later and Hootsuite both describe the same mechanism from opposite ends - Later says the algorithm "prioritizes content that receives quick initial interactions", Hootsuite that it "loves posts that get lots of likes, comments, shares, and saves right after being posted". What you are timing is the first hour, not the whole day.
• Metricool measured the largest Instagram sample we found, 24.4 million posts, and states no timezone anywhere on the page. We cite them below and leave them off the map, because an hour with no clock cannot be placed on one.

Where the studies contradict each other

Every other page on this subject prints one confident grid. These are the places our sources flatly disagree, with both sides named, because that disagreement is the most useful thing we found.

Why this matters less than the rest of the page suggests

Every study on this page is published by a company that sells scheduling software, and most of them tell you plainly that timing is a small lever. We think that is the single most useful thing in the whole category, so we put it here rather than at the bottom.

Only one study we found measured the size of the effect instead of just ranking hours. AuthoredUp, across more than 3 million LinkedIn posts, found the gap between the best and worst day is under 10% for personal profiles, and that weekday against weekend engagement lands within roughly 7%. Company Pages see a larger swing, about 1.7 times between Wednesday and Sunday.

Set against that, the studies here disagree with each other by up to sixteen hours on the same platform. When the disagreement between sources is far larger than the effect any of them measures, precision to the hour is false precision.

The honest version: post in the broad window your audience is awake and reachable, keep the cadence steady, and spend the effort you saved on the post itself. Then replace all of this with your own analytics as soon as you have enough of your own posts to read.

• “Timing can't save a weak post. Think of it as the cherry on top of your strategy, not the cake itself.”

• “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.”

Questions

What is the best time to post on Instagram?

Across the four studies we plot, weekday late mornings to early evenings draw the most agreement, with Tuesday and Wednesday the most consistently named days. No single hour is agreed on: Later says 5am, Metricool says 8pm to 9pm, and Hootsuite calls Later's hour one of the worst of the day. The heatmap on this page shows where they overlap instead of picking a winner for you.

What is the worst time to post on Instagram?

The only near-agreement is the small hours. Hootsuite names late nights after 10pm and early mornings before 8am as worst, and Sprout names weekends as its worst days - though Sprout simply publishes no weekend data rather than measuring it as poor.

Do these times need converting to my timezone?

Not for Instagram. Sprout, Buffer, Hootsuite and Later all publish Instagram windows already normalised to the reader's local time, so the heatmap shows them as published, on your clock. None of them publishes how that normalisation is done.

Does posting time still matter now the feed is ranked?

Less than the studies selling scheduling tools imply, and their own words say so. Buffer: "timing can't save a weak post. Think of it as the cherry on top of your strategy, not the cake itself." Timing works by helping a post collect early engagement, which is a real but second-order effect next to whether the post is worth engaging with.

How often should the schedule change?

Rarely, on this evidence. These studies are refreshed roughly yearly and disagree with each other more than any of them moves year to year, so chasing an updated grid every quarter is noise. Your own audience's data beats all of them.

How we built this

We read each study's own page, transcribed its day-by-day windows, and recorded the clock it publishes on. The heatmap shades each hour by how many independent studies name it. It is a count of agreement, not an engagement score: we never blend numbers from studies that measured different things in different ways.

A study only reaches the map if we can put its hours on a clock. Metricool measures the largest samples in this category and states no timezone on any page we read, so its hours are quoted in the text and left off the grid. HubSpot surveys marketers about what they believe rather than measuring posts, so it is left off too. Both are listed with the rest, with the reason attached.

Most publishers now normalise their windows to the reader's local time, so we plot those as published rather than converting them - converting an already-local window is how these pages usually go wrong. Later's TikTok windows are the exception, published in PST, so those we convert to your clock with daylight saving resolved for today.
