I am a 16-year-old 5'4 male who went through puberty at age nine. my father was 6 foot 2 but my mother is 4'11. my older brother is 6 feet- but i haven't grown at all this year. am i done growing?

Maybe: No growth over the past year & a relatively early puberty suggest you are finished growing taller. Your expected final height based on cited parental numbers would be 5'9" & that still may be possible. An x-ray of your wrist/hand could identify open growth plates that suggest more upward growth is possible. If the growth plates are closed you are done.
