I use KeePass' password generator, which defaults to generating random sequences of 20 uppercase, lowercase, and digit characters. Usually the passwords are between 100 and 120 bits of entropy. I try to use only letters and numbers because they are easier to type on mobile phones and other non-physical-keyboard-driven devices.
