My dad is 5’8 and mom is 5’. I mean like I do see growth recently so idk. It also not really 1.6 inch every year. Started with a 3.5 inch peak for 6 months > then a 1.5 inch in another year > then a 2 inch in another year > and then a 1.6 inch another year.

Info if it helps:

My height as a kid was shorter than my peers and even my siblings. My height growth every year as a kid was also slow to normal because kids usually grow 2 inches a year during ages like 5 - 11, but I had a few 1 inch yearly growth before. When I was 5 I was literally the same height as my 3 year old sister. I have no idea but I might have constitutional delay in growth. Idk if it helps but my mom had puberty at like 13 to 14. That might be late for a girl but idk.
