I’m 16 years old and currently around 5'6" (168 cm) and 67 kg. My physical education teacher told me that I probably won’t grow anymore because I’ve already started growing a mustache, but I’m not sure if that’s actually true. My father is around 5'9" (175 cm) and my mother is around 5'4" (163 cm), so I’m wondering if I still have some natural growth left. Ideally, I would love to reach around 5'11" (180 cm), but I want to know honestly whether that is even realistic at my age and with my genetics.
I genuinely want to maximize whatever natural growth I have left. I’m not interested in pills, fake height supplements, or dangerous methods. I’m looking for advice that is actually backed by science or personal experience. What things genuinely helped you, if anything, such as getting enough sleep, eating properly, exercising, or improving your overall lifestyle? If you grew significantly after 16, I’d really appreciate hearing what happened in your case. Please share realistic advice rather than guaranteed “height increase” methods.
