How Long Will It Take to Read One Piece

Would it be faster to read or watch One Piece?

Most people can read manga a lot faster than they can watch anime (even if you pull the classic trick of watching at 1.5 speed with the subtitles on), so you’ll probably get through the series a lot faster if you choose to read. You’ll also skip the filler episodes, some of which are better than others.

How long would it take to finish One Piece in one day?

With 929 episodes under its belt, each of those One Piece entries runs about 20 minutes if you exclude their opening and ending themes; If you did include those songs, each episode would run about 24 minutes. If you multiply 929 by 20, you end up with 18,580 minutes. Now divide that by 60 to get 309 hours.
