Watch hours are the total hours people have spent watching your channel's public videos. YouTube uses them as the hard entry ticket for making money: the main route into the Partner Programme requires 4,000 public watch hours in the last 12 months, plus 1,000 subscribers.
Only public videos count. Private videos, unlisted videos and deleted videos add nothing, and deleting a video removes its hours from your total.
The window is rolling. It always looks at the last 365 days. So hours you earned 13 months ago quietly fall off the back of the count while new ones come in. A channel that stops uploading can watch its total go DOWN month after month.
Do the maths and you'll see why this number stops most channels. 4,000 hours is 240,000 minutes.
If your average viewer watches 2 minutes, you need 120,000 views inside a year to qualify. For a small channel, that's the difference of an entire career stage. The subscriber count is the easy half of the gate. The hours are the half that takes years, and that's exactly why YouTube watch hours exist as a product: it's the one meter nothing else can move.
Time watched on Shorts does NOT add to your watch hours. Shorts have their own separate gate into the Partner Programme: 10 million public Shorts views in 90 days.
This is the most common surprise in YouTube monetisation. A channel can get millions of Shorts views and still sit at 300 watch hours. If your content is mostly short vertical video, you're on the Shorts route, not the watch-hours route. Pick the route that matches what you actually make.
4,000 public watch hours in the last 12 months, plus 1,000 subscribers, for the main route. There's also a Shorts route (10 million public Shorts views in 90 days) and a lower fan-funding tier that starts at 500 subscribers.
No. Shorts watch time is counted separately and has its own entry route. Watch hours come from normal long-form videos and live streams.
Yes. The count covers the last 365 days, so old hours expire off the back. Deleting or privating videos also removes their hours.
Yes, watch hours are sold like other metrics. Delivery takes days, not minutes, because real watch time has to actually run. Remember YouTube also reviews your channel by hand at the threshold, so the content itself still has to pass a human check.
