How long should you know someone before you say "I Do"?

Hello, my baby sister is getting married. I am excited and scared at the same time. I guess she knew him informally about one year, been dating for about 2 mos, and now she is planning her wedding. I don't particular believe in a formula i.e You have to know someone xyz before you get married. But I do believe you should invest enough time and research to get to know a person. What has been your past experience of people that dated for x amount of time and how long did/ or is the relationship lasting?
