Frequently asked questions

Because neither of you can see the real number. YouTube publishes subscriber counts rounded to three significant figures, so every live counter is projecting inside the same rounding window using its own assumptions about growth. Two sites using different growth estimates will drift apart by thousands within hours and both be inside the window YouTube publishes.

What differs is honesty about it. This site tells you which reading its number is anchored to, how old that reading is, how the growth rate was measured, and roughly how wrong it might be.

It did until 2019. Rounding was introduced partly to reduce the minute-by-minute obsession with the counter — subscriber-count races had become a genre in themselves — and partly to smooth the visible effect of spam-account removals. The exact figure is still available to the channel owner in YouTube Studio; it is just no longer public.

Live means we are actively polling that channel and the anchor reading is under two minutes old. This happens while someone has the page open.

Estimated means the number is projected forward from the most recent daily reading. It is still built on a real measurement, just not a recent one.

Stale means no reading has landed in over thirty-six hours and the projection has been running unchecked for too long to lean on. Treat the number as indicative.

Those are the digits we do not actually know. YouTube’s rounding leaves a window of possible true values; the dimmed digits mark the part of the displayed number that falls inside it. The window narrows on its own as a channel grows without crossing into the next rounding bucket, and collapses when it does cross.

The one-day figure is usually close, because the dominant error is the rounding window rather than the growth rate. Beyond a month the growth rate dominates, and the honest answer is that the range matters more than the centre line — which is why the range is published next to it rather than hidden.

A projection assumes the current pace continues. That assumption is broken every time a video takes off, a channel goes quiet, or YouTube purges spam accounts. The methodology page sets out the error model in full.

A machine, once a day, from a fact sheet of the statistics we calculated. It is not given access to anything beyond those figures and is instructed not to introduce numbers of its own, so it can be uninteresting but it cannot invent a subscriber count. Every one is dated and labelled. There is more detail under how it works.

Search for it on the home page. Looking a channel up adds it to the tracked set for everyone, so the second person to search for it gets an instant answer and it costs no further API quota. Channels that hide their subscriber count cannot be tracked, because there is nothing to read.

No. An account only saves your tracked list to the server so it follows you between devices; without one the list lives in your own browser’s storage. There is no paywall on any number.

No, and it is worth saying so on a site built around the number. A subscriber count includes long-dormant accounts and tells you nothing about how many people actually watch. Views per subscriber, shown in the trend detail on each channel page, is a better rough guide to whether an audience is engaged than the headline figure is.
