how long would it take to watch every youtube video
It would take an enormous amount of time —roughly thousands to tens of thousands of years if you tried to watch all existing YouTube videos at normal speed, and in practice you’d never actually finish because new uploads keep coming in constantly.
Why it’s so huge
Public estimates vary because nobody can count the full library exactly, but one common calculation uses hundreds of millions of videos and an average length of about 11.7 minutes, which lands around 17,800 years of nonstop watching. Another estimate using a larger video count and similar assumptions comes out even higher, around 350,000 years.
The catch
Even if you somehow caught up to today’s uploads, YouTube keeps growing while you watch, so the total target keeps moving. That means the real answer is effectively “you never finish.”
Quick feel
- Normal single-person viewing: impossibly long
- Even with many screens or accelerated viewing: still astronomical
- With continuous new uploads: never-ending
The short version: watching every YouTube video is less a task and more a mathematical joke.
