Best Time to Post on Instagram in 2026

Best days to post on Instagram

Relative posting strength by day, synthesized from the studies cited below. Strongest days: Wednesday, Tuesday, Thursday. Weakest: Saturday, Friday.

Best times to post, by day

Recommended posting windows in US Eastern (ET). Darker cells are peak windows; lighter cells are solid secondary options.

• Monday: Hootsuite flags a strong 3-9 p.m. block, and Buffer's top Monday slot is 7 p.m. (then 6 and 8 p.m.). Sources split on mornings, so the shared signal is mid-afternoon into evening. Hootsuite names Monday a top-three day; Buffer ranks it mid-pack.
• Tuesday: One of the most consistently strong days across sources. Sprout Social cites 1-7 p.m., Buffer's best slot is 7 p.m. (then 3 and 5 p.m.), and Hootsuite adds a secondary 5-8 a.m. morning window worth testing.
• Wednesday: The single most-cited best day. Buffer's top overall slots include Wednesday noon and 6 p.m.; Sprout Social shows a broad 12-9 p.m. peak (plus an 11 p.m. late-night spike). Strongest day to prioritize if you only post once.
• Thursday: The one day where mornings clearly win: Buffer's single best slot all week is Thursday 9 a.m. (then 8 and 7 a.m.). Sprout Social adds a 12-2 p.m. peak and Hootsuite a 4-5 p.m. window, so a midday-to-late-afternoon post is a solid second option.
• Friday: A weak day in most studies. Buffer ranks it among the worst (only late-evening 9-10 p.m. salvages it), while Hootsuite still sees a modest ~4 p.m. window. Treat as lower priority and lean late afternoon or evening.
• Saturday: The weakest day across nearly every source (Buffer, Sprout Social and Later all flag it lowest). Hootsuite sees a late-morning bump around 11 a.m. If you must post, late morning is the least-bad slot.
• Sunday: Below midweek but better than Saturday. Hootsuite cites an early-afternoon 12-3 p.m. window; Buffer's Sunday strength is concentrated late evening (9-10 p.m.). Sprout Social rates the weekend lowest overall, so test before committing budget here.

What the data says

How to use these times

1. 1

   Treat these windows as a starting hypothesis, not a rule. Open Instagram Insights (Professional Dashboard > Total Followers > Most Active Times) to see when your specific audience is online, then test posts against the aggregated windows above and keep what outperforms.

2. 2

   Match the window to the format. Later's data shows Stories peak earlier and later (a 6-8 a.m. morning window and a 7-9 p.m. evening window) while feed posts peak around 5 a.m. and carousels and feed content also do well midday-to-evening. Schedule each format to its own pattern.

3. 3

   Reconcile the morning-vs-evening split with your own data. Later's '5 a.m.' reflects catching users on their first scroll in their local timezone, while Buffer and Sprout emphasize midday-to-evening. If your audience is national, an early post can ride the algorithm's early-engagement signal into the day; if it's local, evening may convert better.

4. 4

   Post consistently before you optimize for the exact minute. Every study agrees the day-of-week and broad daypart matter far more than hitting an exact hour, and a steady cadence trains the algorithm and your audience better than chasing a single 'perfect' slot.

5. 5

   Down-weight Friday and Saturday. They are the weakest days in nearly every study, so save your strongest creative for the Tuesday-Thursday midweek peak and use weekends for lower-stakes or evergreen content.

6. 6

   Account for timezone spread. If your followers cluster on the US West Coast or span multiple zones, shift these Eastern windows accordingly. For broad national audiences, posting toward the late-morning-to-early-afternoon ET band reaches the most zones at once.

Methodology and sources

This guide aggregates publicly published best-time-to-post studies from Buffer (9.6M posts), Sprout Social (~2B engagements across ~307,000 profiles), Hootsuite (1M+ posts), and Later (6M+ feed posts), fetched directly from each publisher in 2025-2026. Crowbert has no proprietary posting dataset, so the windows above are a synthesis of those third-party studies, which disagree meaningfully (notably on early-morning vs. evening peaks because of different methodologies and timezone handling). Use these as an evidence-based starting hypothesis and personalize them with your own Instagram Insights and post-performance data.

All times are in US Eastern (ET) unless noted. Source studies report times either in the audience's own local timezone (Buffer, Later) or normalized across global profiles (Sprout Social), so treat these as a starting point and adjust to where your followers actually are. Check Instagram Insights for your audience's most-active hours and convert to their dominant timezone.
