Nine boards, each rebuilt from a daily snapshot of the broadcasts we tracked. Every board states how it is calculated and which channels are excluded, because a ranking you cannot audit is just an opinion with a table around it.
Total estimated hours watched divided by total hours streamed in the period, across broadcasts we tracked. Channels need at least 2 streams and 3 hours of tracked airtime to appear.
The highest single viewer count we observed during the period. Because it is sampled rather than continuous, the true peak may be marginally higher.
Estimated hours watched: average concurrent viewers multiplied by broadcast duration, summed across tracked streams in the period.
Current follower total as most recently observed. Ordering reflects our latest observation, not a live reading.
Followers gained between our first and last observation inside the period. Channels tracked for less than the full period are measured only over the time we actually observed.
Percentage change in average viewers versus the immediately preceding equal period. Channels whose previous period was too small for a percentage to be meaningful are excluded rather than shown with an inflated figure.
Total tracked broadcast time in the period.
A composite of recent viewership growth, hours-watched growth, follower growth and activity, measured against each channel’s own baseline and scaled by data confidence. Deliberately not a ranking by size.
Small and mid-sized channels (10–2,000 average viewers) showing sustained growth over both 7 and 30 days, ranked by momentum against their own baseline.
What these boards do and do not cover
Rankings only include channels we track, measured only across broadcasts we actually observed. A channel we started tracking recently is measured over the time we watched it, not over its Twitch lifetime, and channels below each board’s minimum activity thresholds are left out rather than padded in with thin data.
