How tall might i be?

im a 17 year old boy and im 5'8" my dads is short 5'6", but he was malnourished as a baby and both of his brothers and his father are much taller, more like 6 footers. my uncle on the other side (picking him because hes also a man, is about 6'0 too. i dont know about the rest of them but my granpa, told me he was one of the shortest people for his age till he was 19 and he had a growth spurt and was pretty tall then? what can i expect?
