@Creideiki true, but it's still better to use paraphrases.
4-word, English, all lowercase paraphrase with single space word separators: 8.5 * 10^20 combinations of words. That is more than all the possible combinations of 10 printable ASCII characters (6.6 * 10^19), except easier to remember.
Factor in uppercase characters, punctuation (which dictionary attacks cannot find) and other languages and it's even better.
