Instagram Stories by account size: reach change — 2026 vs 2025 (%)

Reader Note:
The fall holds at every account size; -24% is the largest, recorded on huge accounts.
Evidence:
Observed behaviour
Vendor interest:
Moderate — This comes from a company with a commercial interest in this market, so it is not a neutral source.
Sample:
24,364,803 Instagram posts from 375,118 accounts worldwide, covering January and February 2025 and January and February 2026 — a two-month window, not a full year. Accounts with zero publications were excluded, as were posts with zero impressions or zero interactions, so every average in the study is computed over posts that got at least one interaction. Accounts were segmented by follower size into Huge (1M+), Big (100K-1M), Medium (10K-100K), Small (2K-10K) and Tiny (0-2K). Outliers were not removed. Growth has a non-obvious definition: an account counts as having grown only if it crossed into a higher follower tier, so an account that went from 3K to 9K followers is not counted as having grown, and the study's own methodology notes that crossing Tiny to Small takes far fewer new followers than crossing Medium to Big — growth rates are therefore not comparable across tiers.
