Usually, puberty starts between ages 8 and 13 in girls and ages 9 and 15 in boys. This wide range in ages may help explain why some of your friends still look like young kids whereas others look more like adults.
Everyone is different, but puberty usually starts in boys between the ages of 10 and 14. You and your friends may not start puberty at the same time. That's normal. In boys, puberty is considered precocious -- or early -- if it begins before or about age 9. Puberty is considered delayed when there are still no signs of sexual growth or development by the time a boy reaches age 14.
