Instagram Growth Study: Median Account Gains 346 Followers in First 30 Days

A growth statistics page built from 164,963 daily follower readings across 7,271 Instagram accounts reports a median gain of 346 followers over the first 30 days for 981 accounts, with 86% of them growing. The authors applied a reading window that accepts the closest measurement within three days of each target date, so missing daily readings do not discard accounts or mix in readings from the wrong day. Accounts only count toward each milestone if they still have a reading on that day, which is why sample sizes shrink from 981 at day 30 to 417 at day 90. Accounts with implausible jumps or drops, usually caused by username changes or failed readings, were excluded, along with accounts above 100,000 followers and those starting from June 2026, whose repeated counts were treated as stale data. Growth is front-loaded, with the median rising to 483 by day 60 and 533 by day 90.
