FAQ
What is Instagram reach?
Reach is the number of unique accounts that saw your content. It is different from impressions, which can include repeated views.
What is a good reach rate on Instagram?
It depends on account size and niche. Smaller accounts often have higher reach rates than large accounts.
How is monthly reach estimated?
The calculator multiplies estimated reach per post by posts per month. It is a rough planning estimate.
Should I use reach or impressions for brand deals?
Reach is usually cleaner because it counts unique accounts, while impressions can include repeated exposure.
Can Reels reach non-followers?
Yes. Reels can reach non-followers, so actual reach can be higher than follower-based estimates.
