After a couple of decades, One Piece has amassed a whole bunch of chapters. To date, there are more than 1,000 chapters of the series to binge, but some simple math will help contextualize just how long it would take to read all those entries.
Clearly, One Piece has a lot of baggage behind it, but the series has thrived for decades because it is worth binging. As the series heads towards its final arc, things are only going to get wilder for the Straw Hats. So if you want to see history take place in realtime, it is certainly worth catching up on One Piece.
With 1,059 chapters at hand right now, you can simply multiply the number of chapters by eight minutes to figure out the manga's total read time. That is 8,472 minutes of reading or a little less than 142 hours. And if we divide by the days of the week, well – it seems One Piece could be read in six days if you did nothing but binge the manga.
