The minimum age is 12 though on the website it says 13 it is really 12.
An 11 year old could play IMVU, but shouldn't. There are lots of other games for 11 year olds to play. IMVU has some "words" that kids don't need to see. Even though you have to be 13+ to play IMVU, some kids lie about their age and still play. Hope this answers your question. :D
