What is the best day to post on Instagram?
Tuesday and Wednesday. In Sprout Social's March 2026 study of nearly 2 billion engagements across 307,000 profiles, these two days showed the highest peaks. Monday and Thursday have useful but shorter windows, and Friday had no significant peak at all.
Saturday had the lowest engagement of the week, with Sunday close behind.
What time should I post on Instagram in the UK?
Early to late afternoon, UK time, if your followers are mostly in the UK. The study reports local time, so these windows apply directly to a UK audience:
- Monday: 2pm to 4pm
- Tuesday: 1pm to 7pm
- Wednesday: 12pm to 9pm
- Thursday: 12pm to 2pm
Do Reels need different posting times?
Not according to the 2026 data. Sprout says the same windows apply to Reels, photos and carousels. What changes with Reels is how long they keep finding new viewers, so a strong Reel can keep working well after the first few hours.
How do you find your own best Instagram posting time?
Open Instagram Insights on a professional account and check when your followers are most active. Compare that with the windows above, pick two or three slots, and test them over four weeks. Keep whichever brings the most reach and saves.
Planning posts ahead keeps the test fair, because the times stay consistent. Unavoidably Social puts Instagram alongside your other channels on one calendar. Instagram publishing is waiting on Meta's platform review, and we say so on the channel until it is approved.
FAQs
Is it worth posting on Instagram at the weekend?
Weekend engagement is usually lower, so if you post a few times a week, weekday afternoons are the safer bet. Some consumer brands do well at weekends, which is why testing your own account matters.
How often should a small business post on Instagram?
Three to five posts a week is a realistic target for most small businesses. A steady rhythm you can keep up beats bursts of daily posting followed by silence.
Do these times apply to Instagram Stories?
The study looked at engagement with posts, not Stories. Stories are best tested separately using the reach figures in Instagram Insights.
