Haven’t grown since 15
For context, my dad is 6’2” and my mom is 5’5”–5’6”. I’m 18, turning 19 soon, and 5’7”. I’ve always been a late bloomer and less developed than people my age. I haven’t grown much since my initial growth spurt around freshman–sophomore year; I was 5’6” at 16. I’m wondering if I’m done growing or if I could still have some growth left.
My 13-year-old brother is already about ½” taller than me, despite us having the same dad and my mom being taller than his mom. My dad also grew about 3” in his early 20s and was a late grower, though I’m not sure how much that applies to me.
I also look noticeably young for my age. I have very little facial hair—basically the same light mustache since puberty—and only recently started getting a few chin hairs and tiny strands of chest hair. Any insight would be appreciated.
Thank you all!
