The short answer
Organic reach is the number of different people who saw a post without any money spent to promote it: the platform’s feed and recommendations alone decided to show it to them. Paid reach is the opposite, people reached through ads or a boosted post. Reach counts each person once, however many times they saw the post.
Organic reach is usually a small share of an account’s followers, and that share shrinks as the account grows. In Socialinsider’s 2026 study of 872,075 brand posts, Instagram accounts with 1,000 to 5,000 followers reached about 6.65% of their followers per post, and accounts with 100,000 to 1 million reached about 3.5%.
Organic reach by account size
Socialinsider measured reach rate, a post’s reach divided by the account’s followers, for brand pages on Instagram and Facebook from January 2025 to August 2026. The larger the account, the smaller the share of followers each post reached, and the drop is far steeper on Facebook.
| Followers | ||
|---|---|---|
| 1,000 to 5,000 | 6.65% | 4.35% |
| 5,000 to 10,000 | 5.75% | 3.40% |
| 10,000 to 50,000 | 5.50% | 2.70% |
| 50,000 to 100,000 | 4.50% | 1.50% |
| 100,000 to 1 million | 3.50% | 0.50% |
Organic reach by post format
The same study compared formats. On Instagram, the three main formats reached a similar share of followers, with carousels slightly ahead. On Facebook, images and albums reached the most followers and links the fewest.
| Platform | Format | Reach rate |
|---|---|---|
| Carousels | 4.50% | |
| Reels | 4.10% | |
| Images | 4.00% | |
| Images | 1.20% | |
| Albums | 1.15% | |
| Text posts | 0.80% | |
| Reels | 0.55% | |
| Links | 0.20% |
Reach beyond your followers
Much of a post’s organic reach can come from people who do not follow you yet. Instagram’s Help Center explains how: “Both Facebook and Instagram may recommend content, accounts, and entities that people do not already follow. Some examples of our recommendation experiences include Explore, Reels, Accounts You May Like, and Feed.” A post shown in those places reaches past your follower count, which is why a reach rate can sometimes pass what your followers alone could explain.
What can shrink it
Reach can be cut as well as grown. Meta’s overview of the content it shows less of in Facebook Feed says its Content Distribution Guidelines describe content “we think may either be problematic or low quality, so we reduce its distribution in Feed for everyone”, and that how much it is reduced “may vary depending on the number of times the poster or commenter has violated our rules previously”. Posts built to bait reactions are one example.
Why reach rate is not the whole story
Reach rate divides by followers, but much of a post’s reach can come from people who do not follow the account at all, through recommendations, Explore or a share. A post can reach more people than an account has followers, and a format with a low reach rate among followers can still be the one that finds new people. Socialinsider notes that platforms estimate reach and count unique people only.
Organic reach also depends far more on how a single post does than on the follower count. Two posts from one account in the same week can reach very different numbers of people, because each is shown more widely only if early viewers watch, react or share.
How to use your own organic reach
Compare a post’s reach with your own recent posts, not with another account. Divide engagements by reach to get an engagement rate that counts each person once, the way Buffer’s 2026 engagement report calculates it. And watch the trend in median reach per post over months, so one post that spread widely does not hide a slow decline.
Questions
What is the difference between organic and paid reach?
Organic reach is people who saw a post through the platform’s own feed and recommendations. Paid reach is people who saw it because you paid, through an ad or a boosted post.
What is a good organic reach rate?
It depends on account size and platform. In Socialinsider’s 2026 data, Instagram brand accounts reached about 3.5% to 6.65% of followers per post, smaller accounts at the high end. Compare against your own recent posts first.
Why does organic reach go down as followers go up?
Each post is shown to the followers most likely to care, not to everyone. As an account grows, more followers are inactive or less interested, so the share reached falls even when the number of people reached rises.
Can organic reach be higher than follower count?
Yes. Reach counts everyone who saw the post, including people who do not follow you and found it through recommendations or a share.
