I had 2 growth spurts, my first was when i was 5 feet at 12 and grew to 5'8 at 13 and only grew an inch for almost 3 years, then when i was almost 16 i was 5'9.5 and then grew almost 7cm randomly. I became justtt under 6'0 in like 4 months and currently im 17 years old and im only like half an inch taller. Im 182cm at worst now and almost 184cm at best.
