Puberty starts at 11 and ends at 15/16. So puberty lasts nearly 5 years.
it really depends on you body and when it is ready to begin the process but for a boy it normally starts from 10-15 and females strat a bit earlier and what i mean by 10-15 is not how long it last puberty last to about 20 years old
