Best time to post on Instagram (and how to find yours)

Search for the best time to post on Instagram and you'll find four big studies with four different answers. This guide shows what each one measured, why they disagree, and how to find the hours that suit your own followers. Everything below was checked in October 2026.

What the studies say about the best time to post on Instagram

Four social media companies have Instagram timing studies with 2026 dates. Before you trust a headline, look at what each one measured.

Notice the dates in the second column. Later's 2026 page uses posts from 2024, Buffer's covers 2024 and 2025, and Hootsuite's page calls its data its 2025 analysis. Sprout's is the newest, but it covers only three months, from late November to late February, a stretch that includes the end-of-year holidays.

The biggest clash is the early morning. Later found posts published between 3 and 6 a.m. did better than average on every day of the week. Buffer's data names 1 to 5 a.m. as the worst time to post on any day, and Sprout advises avoiding early mornings.

Best time to post Reels on Instagram

Reels split the studies again:

• Sprout Social says its best times for Reels mirror its overall best times, the same midweek afternoons as for photos.
• Buffer suggests evenings, 6–11 p.m., with Wednesday and Thursday strongest. Buffer notes it looked at all post types together, so these aren't Reels-only times.
• Later analyzed over 975,000 Reels and found midnight (12 a.m.) the best time, with Monday the best day for Reels.

So for Reels, the honest answer is to test. Compare Reels with Reels, not with photo posts, because formats can behave differently: Later, for example, found different best times for Reels and carousels. Before you start, make sure your Reels are the right size and length, since a Reel that gets cropped or cut short won't tell you much about timing.

Best day to post on Instagram, day by day

Tuesday is the one day that Sprout, Buffer and Hootsuite all rank among their best. Sprout names Tuesday and Wednesday, Buffer names Wednesday (then Thursday and Tuesday), and Hootsuite names Monday, Tuesday and Thursday. Later picks Monday. If you came here for the best time to post on Instagram today, find today's row:

Later's day-by-day best times are mostly very early: between 3 and 6 a.m. on weekdays, 5 a.m. on Saturday, and midnight, 5 a.m. or 11 p.m. on Sunday. Treat any row as a guess to test, not a rule.

Our free best time to post tool shows these times on your own clock when your followers live in another time zone, and the free content calendar planner lays your test posts out over a month.

Why the studies disagree

Each study answers a slightly different question with a different group of accounts:

• Different accounts. Each company studies posts from its own customers, and their followers live in different places and use Instagram at different hours.
• Different measures. Sprout counts engagements. Buffer uses the median engagement rate (likes, comments, shares and saves divided by followers), so a few viral posts don't skew it. Later also measures engagement rates.
• Different periods. The data runs from January 2024 to February 2026, and each study covers a different slice of it.
• Different ideas about competition. Later suggests early posts face less competition and catch people's first scroll of the day. Sprout's advice is the opposite: post when your audience is already actively scrolling.

Instagram's own explanation of ranking helps here. In Instagram ranking explained (May 2023), Adam Mosseri lists how quickly people like, comment, share and save a post, and when it was posted, among the signals for Feed. So timing can help a post get early interactions. But the hours that matter are the ones when your followers are around, and no average knows those.

How to find your own best time on Instagram

Instagram shows when your followers are active, free, in Insights. According to Instagram's Help Center, insights are available to public accounts, and the follower insights appear once you have at least 100 followers.

1. Tap Profile or your profile picture at the bottom right.
2. Tap Professional dashboard. On a personal account, tap Your dashboard.
3. If you can't see your dashboard on your profile, tap More to open Settings and activity, then tap Insights under For professionals (or Your dashboard under Your insights and tools on a personal account).
4. Tap your followers insight (the Help Center calls it Total followers). Along with growth, top locations and age range, it shows the times your followers are most active on Instagram.
5. Check the top locations too. If most of your followers live in another time zone, plan in theirs.

You can choose a date range anywhere within the last 90 days. Look at the chart on more than one occasion before you decide, because a holiday or one busy week can shift it.

A simple 2–4 week test plan

The most active times show when your followers are online. A short test shows when your posts actually do well.

1. Pick three slots: your followers' busiest hour from Insights, one hour before it, and one time from the studies above that you've never tried, such as early morning.
2. Post at least three times in each slot over two to four weeks, spread across different days.
3. Keep everything else similar. Test Reels against Reels and photos against photos, with similar topics and lengths.
4. Compare posts at the same age, for example three days after posting. Tap View insights under each post or Reel to see its views and interactions.
5. For each slot, look at the middle result, not the best one. One post that takes off can make a slot look better than it is.
6. Keep the winning slot and test one new time each month. Your audience changes as you grow.

How to post at your best time with Unisenda

Once you know your slots, scheduling means you don't have to be on your phone at 5 a.m. or 9 p.m. to hit them. You don't need another app for that: if your account is public, Instagram's own app can schedule reels, photos and carousels up to 30 days ahead, up to 25 posts a day. A scheduler like Unisenda helps when you also post to other networks or want your test slots laid out on a weekly calendar. Unisenda posts to Instagram professional accounts (Business or Creator):

1. Connect your Instagram account in Connections. You approve access on Facebook's own screen, through the Facebook Page your account is linked to; Unisenda never asks for your password.
2. Click Create post, select your Instagram account and add your photos or video. In the Instagram tab, choose the format: a photo, a carousel of up to 20 photos, a Reel or a Story (Stories need a Business account). For a Reel, pick a Cover from a frame or an uploaded image, and add a song from Instagram's licensed music library if you like.
3. Click Schedule for, pick the date and the time to the minute, check the time zone shown, then click Schedule. Unisenda uses your device's time zone, so if your followers live elsewhere, convert their busiest hour to your time first.
4. Save your usual setup as a Preset. Presets remember your accounts, caption, image shape and time of day, so your usual slot is filled in for you. You still choose the date.
5. To lay out a test, open Calendar and choose Week. It's an hour-by-hour planner: click an empty hour to start a post at that time, or drag a scheduled post to another day or hour (with Undo).

Before you schedule, Unisenda flags things Instagram would reject, such as a photo shape it won't take. Scheduled posts go out from Unisenda's servers, so your phone and computer can be off, and each post's result links to the live post. Unisenda doesn't show analytics, so you'll still compare results in Instagram Insights.
