Mark Zuckerberg announced Instagram had reached 3 billion monthly active users on 24 September 2025, and said on Meta’s Q2 2026 earnings call that Instagram had reached 2 billion daily active users. Those two figures are the reliable backbone of any Instagram statistics page; almost everything else circulating is estimated.
Engagement, meanwhile, is going the other way. Socialinsider’s 2026 Instagram benchmark reports an average engagement rate of 0.48%, down 24% year on year.
Size
| Statistic | Figure | Source |
|---|---|---|
| Monthly active users | 3 billion | Mark Zuckerberg, 24 September 2025 |
| Daily active users | 2 billion | Mark Zuckerberg, Meta Q2 2026 earnings call |
| Time spent | grew double digits year over year in Q2 2026 | Susan Li, Meta Q2 2026 earnings call |
| Potential advertising reach | 1.99 billion | DataReportal, Digital 2026 mid-year update, April 2026 |
| Meta apps combined, daily | 3.60 billion | Meta Q2 2026 results, 29 July 2026 |
Note that DataReportal’s 1.99 billion advertising reach is lower than Meta’s own 2 billion daily actives, which shows how conservative ad-reach modelling can be against a company’s own figure. Neither is wrong; they measure different things.

United States adoption
Pew Research Center’s Americans’ Social Media Use 2025, published 20 November 2025 from a survey of 5,022 US adults fielded 5 February to 18 June 2025, reports that half of US adults (50%) ever use Instagram. That places it behind YouTube at 84% and Facebook at 71%.
Pew also finds a clear gender gap: 55% of women use Instagram against 44% of men.

Engagement in 2026
Two studies, both dividing interactions by follower count, both published in 2026:
| Study | Instagram median | Sample |
|---|---|---|
| Socialinsider 2026 Instagram benchmarks | 0.48% | 35 million posts from 447,613 accounts, Jan to Dec 2025 |
| Rival IQ / Quid 2026 benchmark report | 0.30% | 150 companies per industry from a 200,000+ company database |
The gap is sample composition, not arithmetic. Socialinsider’s formula is likes plus comments divided by followers; note that saves and shares are excluded, so a tool that counts them will report you higher than this benchmark.
Engagement by format
| Format | 2026 rate | Q2 2026 | Average posts per month |
|---|---|---|---|
| Carousel | 0.55% | 0.50% | 5 |
| Reel | 0.52% | 0.48% | 8 |
| Single image | 0.37% | 0.33% | 7 |
Carousels lead on a per-follower basis while reels are published most often. That is not a contradiction: reels usually win on reach to non-followers, carousels win on interaction from your existing audience. Which one looks better depends on the denominator you pick, which is worked through with arithmetic in what is a good engagement rate.

What is not published
Instagram does not release follower-count distributions, average reach per post, hashtag performance data, or a breakdown of reels versus feed consumption. Every “average Instagram reach” figure you encounter comes from a third-party sample of accounts that agreed to share their analytics, which skews toward brands using paid tools. That is fine as long as it is labelled, and it usually is not.
How to use these numbers
A benchmark is a starting point for comparison against your own trend, not a target. Comparing a 1,000-follower account to a 0.48% median is close to meaningless: one post that reaches beyond your followers will double your monthly rate, and a quiet week will halve it.
What holds up:
- Pick one formula, including whether saves count, and recompute your last 12 months with it. The engagement rate calculator handles the conversions.
- Split your own data by format before comparing to anything external. The 0.37% to 0.55% spread above is likely larger than any change you will get from posting times.
- Watch reach and saves separately from the rate. A falling rate with rising reach is usually growth, not decline.
For timing, the Instagram posting time data is a reasonable place to start testing, and how many hashtags to use matters less than format does.
Getting your own numbers out
Instagram’s in-app insights are useful but hard to compare across months, and they do not sit next to your other platforms. BulkPublish pulls per-post metrics back from the Instagram API and keeps them alongside the posts, so the reports export gives you raw counts you can run one consistent formula over.
