This generator uses a different wordlist with about 18000 words.

Using a quick back-of-the-napkin calculation, you get roughly this amount of entropy from 1password's wordlist when compared to random alphanumeric strings [a-zA-Z0-9]:

  - 5 words ≈ 12 chars
  - 6 words ≈ 14 chars
  - 7 words ≈ 17 chars
  - 8 words = 19 chars

If we take 5 words as the minimum you'd want to use on a web service:

  - halvers persia dutiful manes party
  - append medalist society duke disobey
  - acoustic halo assuage upkeep dexter
  - area theist motile align trespass

As a non-native English speaker (which should be obvious from my strained speech), I'd say it's rememberable enough.
