If you want a fun and visual way to check your passwords, take a look at the passwordmeter webpage. It contains a password checker which shows you the strength of your password and breaks it down into many factors, showing their relative weight in the equation and how well you do in each.

It adds points for character count, number count, symbol count and so on, and deducts for things like letters only passwords, consecutive numbers, sequential letters and so on.

It’s actually quite a useful tool if you have a password and want to modify it a bit. You can add a number instead of a letter, replace a consecutive letter with a symbol and so on.
